repair lines on lcd screen free sample

TV screen lines are an irritating occurrence, and many different issues with the TV can cause them. This article will go over what causes this, whether or not you can fix it depending on the cause, and how to fix it.

When any part of a TV"s display gets damaged, corrupted, or is defective, it can cause lines to appear on the screen. Some TV parts that can cause horizontal lines to appear are the LCD panel, T-Con board, or row drivers.

Issues with these parts can happen for many reasons, and the way your lines appear can tell you a lot about what"s wrong. If the lines are new, one of these parts was likely damaged.

If you"re seeing colored horizontal lines, it may be because of the T-Con board. If other parts don"t seem to be an issue, this part of the TV could be causing the lines.

If lines appear on your TV, you"ll want to inspect the TV itself. You can fix some issues that cause lines to appear, but others may require a professional or a new TV altogether. Some of the most common causes of horizontal lines are:

LCD screen damage. The LCD provides your TV display with light. If you"re handy, you might be able to fix this by doing a little work with the insides of the TV, which you can read about below.

Other devices you"ve connected to the TV. They may also be having issues of their own or might not be compatible with your TV. In this case, you"ll have to inspect the device instead of the TV.

All these issues can be fixed, though it ranges in difficulty. If you"re unsure how to repair your TV, you may want to get the TV professionally repaired.

Knock or tap on the back of your TV. If the issue is with cable connections, this could solve the problem. It could also indicate a problem with your T-Con board. It won"t fix the issue, and the lines may reappear, but it can give some insight into the problem. If it"s your T-Con board, you"ll want to have T-Con replaced.

Run a picture test on your TV. It"s a built-in feature on newer TV"s which allows you to see if the TV display is corrupted. Doing this may look different depending on your TV, but generally, you can go into the settings and find a support option or just a picture test option.

Take a look at the LCD screen. If it"s damaged, you may want to get the screen repaired or replaced. It may be a less costly option than buying a new TV altogether.

Vertical lines on a TV appear for the same reasons as horizontal lines: loose cables and wires, screen damage, or a faulty T-Con board. Leaving the TV turned on for too long can also cause vertical lines.

The steps for fixing lines on your TV will also work to fix TV glitches like flicker and stutter. For example, check the cables and connectors and ensure there"s no issue with your input device.

If your TV screen looks blue, it could be faulty connections, a defective backlight, or incorrect color settings. Some LED TVs naturally have a blue tint, which you can offset by changing the color temperature.

To fix screen burn on a TV, adjust the brightness settings and enable pixel-shift. Sometimes playing a colorful video with fast-moving action for half an hour might help.

Actually, not every damage in #LCD screen requires screen replacement.There are repairable damage categories, and there are the irreparable ones. For example...

Bought a new smartphone or want to check on the old smartphone matrix display? In this program you can test your LCD screen for the presence of dead / broken pixels and repair it. You can detect any stuck or dead pixel on your LCD screen.

If you detect any stuck or dead pixels you will be able to try to cure them. Provide easy way to fix the stuck pixel. The program will try to use different means for the treatment of stuck pixels. Also works for screen burn-in. Start and wait on the smartphone or tablet this app until the dead pixel or stuck pixel has been repaired or unstuck.

Dead pixel is stuck point or several points of the matrix screen, which does not properly reflect the color. Sometimes they are almost invisible, and you can be the owner of them without even noticing it. There are several treatments for dead pixels screen. Mechanical - physical impact directly on the affected area and a soft-that and it has me. We strongly recommend not to use the first method is for advanced users, as it is dangerous for the screen matrix.

The program can repair: Partial sub-pixel defects, Stuck sub-pixels, Dead or Broken (bad) pixels, Stuck versus dead pixels, Dark dot defects, Bright dot defects, phantoms (matrix burnup).

If within a few hours of program works the pixels is not revived, so they can not be brought back to life in this way - contact the service center. Fix your screen with this programm.

I"ve moved up 3 phone models since using this, an A21, A42, now a Samsung Z Fold 4. This app still works wonderfully! I don"t get noticeable lag, however after running this I notice a differece. I tap (or swipe) with one finger, but crazy fast with a light touch. I run this once a month or so, then it always feels better, smoother, and even quicker. I wouldn"t say this is a "last resort" app, but a great maintenance app. Kudos! Been using a while now, very happy! (only a 5 second ad at end too!)

Q:"Vertical lines on iPhone 11 screen!! This is what happen to my phone after I bought it 3 days. Several lines appeared on the screen suddenly. Any idea why it happens? Any other user facing the same problem with me?" – From an iPhone 11 user

There are always a large number of reports from users stating that they find vertical lines on iPhone screen. This is an old problem, starting with the iPhone 4 and continuing through the iPhone X, 11 and 13. the color of the lines may vary from black, red, blue, green, pink, grey or purple. It could result from physical damage and software problems. Anyway, to solve this problem, you should follow the 10 solutions below, so that you can get rid of the lines while reducing the cost of the repair to the minimum.

The colored lines on the iPhone screen in vertical direction could be caused by a few things. No matter which specific situation you"re encountering, the following content will give you some idea of why.

The vertical line problem often occurs with Apple users and you might not know what to do when it appears on your screen. Here a video tutorial will lead you to the right place and guide you to fix this issue clearly.

A force restart is similar to taking out the battery and putting it back on. It is going to completely shut down all the apps and programs running on your iPhone. Whenever you see there are lines across the screen, you can fix it easily by hard rebooting your iPhone. After the hard reboot, the lines on the screen may disappear. To hard restart your iPhone, follow the tutorial enclosed below.

iPhone 6 or former iPhones: Press the "Power" and "Home" button on your iPhone simultaneously for around 13 seconds. You will feel the vibration of the phone, then it will turn on.

iPhone 8 and later iPhones: Press the "Volume Up" button and release it quickly, then press the "Volume Down" button and release it quickly; then hold the "Power" button until you see the Apple logo on the screen.

It might seem ridiculous, but in some cases, iPhone screen lines vertical problem are caused by things as little as water drops or dust. These things can be difficult to notice when you have a screen protector on the screen. If the water drops or dust get stuck between the screen and the screen protector, it is natural that there will be vertical lines across the screen. Therefore, you might as well remove the screen protector, clean the screen with a cloth and see if the lines have gone.

Essentially, cycle charging means charging the battery to 100%, then using it until it drains to 0%. When the phone is charged to capacity again, the vertical lines might disappear.

It is also possible for vertical lines to appear when LCD cables become disconnected from the logic board during sudden jolts or a fall. A slightly shifted iPhone screen does not necessarily mean that it is damaged; it is just a slight shift.

It might be workable to remove the vertical lines by gently pushing the iPhone"s screen back into place to reconnect the cables with the logic board. Make sure that you do not apply too much pressure to the screen in order to prevent the screen from breaking further. The steps are as follows:

This issue may result from the bugs of some outdated iOS versions. A user complains to us that vertical lines on iPhone 5s screen, and simply updating the system works. We understand that some users may think that iOS updates are useless in general, but that is not true. Except for the updates of new features, iOS update often contains bug fixes, which is very important to the normal function of the iPhone.

Step 2. If there is an available update, press the "Download and Install" button to confirm your update. The updating process will begin, what you need to do is just make sure the Wi-Fi connection is good and wait for the update to finish.

Firstly, install and launch Joyoshare UltFix on the computer. Next, plug your iPhone into the computer, and click on iOS System Repair section. After that, hit the "Start" button to proceed.

You are now in the mode selection window. To avoid losing data, choose the "Standard Repair" and click on right-arrow button. If your device failed to be detected, refer to the on-screen operations to enter DFU/recoevry mode.

Some of the info about your iPhone will be displayed on the screen. Make sure all the info is correct and change the wrong points. Then click the "Download" button to download the matching firmware package.

Lastly, click the "Repair" button. The downloaded firmware package will be unzipped, and the program will start to fix the vertical lines on your iPhone screen. A few minutes later, the repairing process will finish, and the lines on the screen will disappear.

No matter is purple vertical lines on iPhone screen, or other colors, these ways may help you. A factory reset will be needed in the way. In this process, your device is wiped and returned to its original factory settings. All your data will be lost. Before restoring your data, ensure that it has been backed up. To revert to factory settings:

Step 6. Ensure that the factory reset is completed by giving the device some time to do so. You should check whether the vertical lines have disappeared after restarting your device.

Another alternative to restore your iPhone with vertical lines to default settings is to using iTunes. As we all know, iTunes always be regarded as an official Apple solution to help troubleshoot some software issues. You can make it by directly connecting iPhone to the latest version of iTunes, click iPhone device sign, then go to Summary → Restore iPhone → Restore.

The DFU mode, Device Firmware Update, can be tested to restore your iPhone. This way clears data on your iPhone and reloads settings by default. You can first enter DFU mode and then do operations below:

As we mentioned in the beginning, the vertical lines on your iPhone screen are usually a sign of physical damage to your hardware. If you see the lines after dropping your phone, it is very likely the screen or the motherboard is damaged. In this case, letting the Apple technicians fix the hardware damages will be much safer than repairing it on your own.

It is common for smartphone devices to have vertical lines. A variety of gadgets are affected, not just iOS devices. Luckily, vertical lines on iPhone screen can be dealt with by most of the solutions listed here. Note that some of the methods mentioned above may lead to data loss, so we strongly recommend you to back up data in advance or use Joyoshare iOS System Recovery directly, which will not cause data loss and has a very high success rate. We hope that one of the methods in this article can help you.

Have you ever left your TV or monitor on for days, stuck on the same image? You return to your screen, only to find an image burned into the display. No matter what you do, it won"t go away. It is a permanent image burn.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

In some cases, you can minimize the image burn effect. In others, you can remove the image burn completely, so long as it hasn"t been burning too long.

Before flat-screens and crystal displays, most TVs and monitors featured CRT (Cathode Ray Tube) technology. In CRTs, individual pixels comprise a red, blue, and green phosphor component. Depending on the intensity of each phosphor component, the pixel appears to the human eye as a unique color.

When a particular still image remains for too long, the intensity of each phosphor component diminishes at an uneven rate. The result is a ghost image on the screen, which is known as image burning.

Plasma displays use plasma, a gaseous substance containing free-flowing ions. When the plasma is not in use, the particles in the plasma are uncharged and display nothing. With the introduction of an electric current, the ions become charged and begin colliding, releasing photons of light.

This is a very simplified version of how a plasma screen works. However, the main thing to understand is that plasma screens use phosphor material (like CRTs) to turn those photons into images.

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

First, let"s tackle plasma screen burn-in. Remember why CRTs experience image burn? When a still image remains on the screen for too long, the phosphor components in each pixel wear out at different rates. The uneven burn rates leave behind a ghost image, forever etched into the screen.

Plasma screens also suffer from phosphor deterioration. Plasma burning occurs when pixels on the screen are damaged through long exposure. The phosphor loses its intensity and only shows the light it was fed repeatedly. In this case, the still image, which causes the burn.

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

Image retention is a different issue from image burn (although it is a precursor to image burn). For example, you"re using an image of a steam train as a reference point for a drawing. You have the steam train image on your screen for a few hours before you decide to play a video game instead.

When you load up the video game on the screen, you can still see the faint outline of the steam train on the screen. The steam train image will remain for a short while, but the movement and color changes of the video game (or film, TV show, or other media type) should erase the retained image.

The other thing to consider is that LED and OLED image burn-in, when it happens, is irreversible. That"s because of how LED and OLED screens work. Individual pixels within an LED display decay when they emit light.

Under normal use, an LED, OLED, or QLED screen won"t suffer image burn. However, if you leave your screen on a single channel for hours every day, then burn-in can become an issue, as it would with almost any screen.

Issues arise when a screen shows a single news channel 24 hours a day, every day, causing channel logos to burn-in, along with the outline of the scrolling news ticker and so on. News channels are a well-known source of television burn-in, no matter the screen type.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

The best fix for screen burn is to prevent it in the first place. Okay, that isn"t super useful if your screen is already experiencing image burn. However, you should always try not to leave your screen on a still image for too long. The time it takes for an image to burn-in varies from screen to screen, between manufacturers, sizes, and panel type.

My personal rule of thumb is to turn off the display if I plan on being away for more than 15 minutes. That way, it is difficult to get caught out, plus you save yourself money on electricity costs and monitor or TV wear and tear.

Another prevention method is to reduce screen contrast as much as you can. Unfortunately, most screens aren"t calibrated correctly, often pushing the contrast and brightness settings too high.

Lower contrast means the lighting across your screen is more even. This means less strain on specific areas of the screen, which helps protect against image burning.

If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.

Unfortunately, this won"t work for extreme cases. Some TVs will have a built-in pattern swiping option that basically accomplishes the same thing (filling your screen with random patterns).

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

Other modern screens feature built-in screen refresh functions that the manufacturer will advise using to remove image retention and image burn issues.

The best tool for fixing ghost images is JScreenFix. The original program helps fix monitors with dead pixels, but the same company also released an "advanced" version of the tool, known as JScreenFix Deluxe.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

You can find the free version of the Deluxe app online, but it is limited to 20 minutes running at a time. Furthermore, we"re not going to link out to the versions you can find online as we cannot verify the security of these installations. If you do use the Deluxe version, you do so at your own risk.

Another option is to set a completely white desktop background and leaving to run for a few hours. The solid color might reset the image burn. A solid color background is more likely to help with image persistence than image burn, but it is still worth trying.

If you have television burn-in, you can attach a laptop to your TV using an HDMI cable, extend your desktop to the television, and share the white screensaver. Hopefully, that will shift your television burn-in.

The team over at ScreenBurnFixer offers a few different ways you can attempt to fix screen burn on your TV or monitor. As with any other screen burn-in fixes, their chance of working depends on the scale of the issue.

You can head to the ScreenBurnFixer Video page and find a video that matches your screen type, then let the video play for as long as possible (we"re talking multiple hours, not a quick half an hour blast). Alternatively, head to the Chart page and find your device or a device that matches your specifications.

There are several ways you can attempt to fix screen burn-in. The results will vary between the screen type and the level of burn-in. A screen with extensive image burn may not clear entirely, although you might see an improvement.

Some screen degradation over time is understandable. However, if you follow the steps in this guide, you"ll protect your screen from image burn before it becomes a permanent issue.

However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.

If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.

Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.

A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.

Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.

A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.

Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!

On top of call difficulties, a broken speaker can also cause problems when watching videos or listening to podcasts. First, carefully check your phone to determine if there is any external damage. If nothing is visible, make sure the latest software update is installed on your device. In addition, try some basic troubleshooting by turning your phone on and off while leaving it unplugged.

Once a phone has water damage — from small spills to a full liquid plunge — there’s often no easy fix. The first step should be to check if your smartphone’s Liquid Contact Indicator has been activated. Most models, including Apple, LG and Samsung, have small visible indicators to show whether water damage has occurred. Consider peace of mind for those inevitable accidents with Verizon’s Verizon Protect or  Total Mobile Protection. Not only is your phone covered if it gets water damage, you may be eligible for a full replacement that same day.

From the rays in a hot car to a sunny day spent at the beach, high temps and direct sunlight can cause serious and lasting damage to a smartphone. Extreme heat can damage a smartphone’s internal components and result in slower speeds or even loss of data. And often the damage is not visible from the outside.

Before you panic, get your phone back to room temperature and exit all apps. Look over the exterior of the phone to see if the battery, which is especially sensitive to extreme heat, has leaked. And in all future situations, make sure to follow manufacturer recommendations. For example, Apple recommends not using a smartphone in temperatures above 95 degrees Fahrenheit.

I’ve owned a Toshiba M55-S3294 since October, 2005. I’ve seen your first example on my own laptop only once and it went away when I rebooted the machine and has never appeared again but it’s nice to know replacing the LCD isn’t to hard after reading around your site.

I do have another question about the same laptop. Can the lid over (mine is copper) be removed without taking the LCD out? I’ve read you can change the color, so before I go looking for one on eBay, I wanted to know what I was getting myself into.

Since you’re in the business, do you have any M55 covers for sale? I tried eBay. No luck. I’m wanting the grey/platium colored one. Currently I have the copper color.

I have a Satellite P30 and today a vertical strip approximately 1 inch wide down the left hand side of the screen turned white. I can move my mouse cursor over to where the “Start” button is in Windows, and activate the “Start” button, however, I can’t see the button or the mouse cursor. Any ideas what might be the cause and solution to this problem?

Most likely it’s the LCD screen problem. Just in case try to connect an external monitor and check out the video output. If you see the same vertical strip (very unlikely), then it’s onboard video problem – the motherboard problem. If the external video is fine, then I would suspect the LCD screen itself. Try to twist the screen, apply some tension to it. Does the vertical strip changes location, color or width?

my screen is dim, it flickers but no lines like in these exampes. the external monitor works fine. i have a m35x-s111 sometimes i can make out whats on the screen but most of the time its to dim. please help. great site

I have an interensting situation. When first powered on, there is a pink tint to the display. After about 10-15 seconds, the display blanks out. If I shine a flashlight on the display, I can see that there ie everything there. If I close the lid and place the machine into suspend mode and open it again, the display lights up and then goes off again. I have determined there is a magnetic switch near the keypad that places the machine into suspend mode. If I place a small magnet near the proper spot, the system goes into suspend mode and then will come out again. As I do this the display lights up for a few seconds and then off again. Keeping a magnet near the switch seems to keep it on for a while longer.

My question is this. Is this switch bad or is there a problem with the backlight or FL inverter? I think it is the switch but, I would like your opinion.

i have a prob that i don’t see discussed yet…..i’m in dire need of help….my toshiba a70 has a prob..it only displays about 11 inches of video on the screen…the right side 3 or 4 inches are black…it works well on an external monitor…no luck updating drivers… also it does the same thing in safe mode…..please gimme a holla on where to go and what to do.i heard you were the best out there

Turn on the laptop and go into BIOS setup. I believe you’ll have to hit ESC key on start up for this laptop to enter the setup. Do you see the same lines when you are in BIOS? If not, then I would say that’s software issue and re-imaging the drive will fix the problem. If the lines are still there, even when you are in BIOS, then it would be a hardware related problem, most likely a bad screen.

I have a Pro-Star 8790. Everything was running fine until a couple months ago. My video distorts at random and forces me to restart my laptop. But I’ve noticed that it only does it when the laptop is plugged in. I listened and heard a quiet clicking noise coming from my power supply (like small sparks) and decided that that was the problem. Now, I’ve bought a brand new AC adapter and it didn’t solve the problem at all. My screen still distorts forcing a restart. I know it’s not a driver problem either. My video card is integrated into my system. I now think it is a video card problem. Does this mean my video card/laptop is fried?

Have you tried to connect an external monitor to the laptop? What about external video, is it bad too? If both screens – internal LCD and external monitor display the same distorted video, then I would suspect the system board. Let me know how it goes with the external video output.

hi, there i have slight problem with my lcd unfortunately the top 8 cm of my screen are gray and do not work, i assume it is completely broken a therefore wish to replace it however my warranty has run out. so i plan on doing it myself, i have two questions relating to this and would really appreciate if you could help me answer them. First of all the laptop in question is a fujitsu-siemens Amilo m7400 and i was wondering if i could replace my lcd with my friends Amilo m7405, in terms of resolution and size they seem identical, however i would appreciate if you could tell me whether or not i am barking up the right tree, my thoughts were that since they were the same model basically that fujitsu would probably have used the same lcd. secondly could you possibly tell me were i could get hold of some sort of manual or instructions. thanks.

It has gotten progressively worse over time. If you apply some pressure to the screen frame, the display will return to normal and the small vertical line will go away. I would assume that this is a loose connection? I intend to remove the frame and re-seat the inverter, LCD cable and do some cleaning. Does this seem like a failing LCD screen? The computer is slightly over a year old.

I would try removing the LCD and putting it back and hope for a miracle. Last month it helped me to “fix” a bad LCD on IBM ThinkPad. The screen was bad, it had some horizontal lines on it. Reseating cables and replacing the video cable didn’t help. But, after I removed the screen and put it back I got a perfect video. I think that when I put all screws on sides back in place, they stretched the screen somehow and made it work fine. I’ve never seen the customer again. I don’t know if it’s going to help you, but I think it worth trying.

I forgot to mention that the screen goes dim every couple of minutes as well. If you give the back of the screen a light tap, it will return to normal. Can you give me any ideas of where to look for a replacement LCD if that is the problem?

With backlight it could be a loose connection problem, try reseating cables on the inverter board. To find a replacement screen, you’ll have to search by the part number. You can find the part number on the back of the LCD screen and it looks like: A000002050 (you might have different part number). Try searching through Google or on eBay. LCD screens are very expensive and very often it doesn’t make any sense to replace the screen, it’s better to buy a new laptop.

If you cannot find the part number for the LCD, give me more info about your laptop: model number and part number from the bottom and I’ll look up a part number for you.

just an update, but disassembling the LCD and re-seating the connections as well as the inverter seems to have fixed the problem. Thanks for your advice.

hello sir, i have a compaq armada M700 laptop…since yesterday i am getting a horizontal line exactly at the middle of the screen. every thing is working absolutely fine. the line is about half a milimitre thick. what should i do…take it to a techician or can i repair it myself

I woke up this morning, turn on my Dell Inspiron 6000 and theres a vertical line. Reboot, Reboot in safe mode and line still there and everything runs fine. After reading the great info on this site it seems a my screen has gone bad. Below is a link to my screen while XP is booting. I need a new screen right? Just wanted to get some feedback before I go spending on one. Thanks in advance.

It looks like a bad screen. From my experience, this kind of failure (thin vertical line across the screen) is not related to a failed video cable, bad connection or bad video card.

I have blue and purple vertical lines along the bottom 40% of my laptop screen and absolutely no image (entirely lines). The top 60% of the screen works great! I tried contacting Gateway but they won’t even answer me as to what it could possibly be without me paying them $3 per minute for cusomter support! Argh! Any advice on why only part of the screen is on the fritz? Thank you.

Start laptop troubleshooting with connecting an external monitor. That’s the first thing to do when you have a bad image on the LCD screen. If the same blue and purple vertical lines occur on the external monitor, then it’s the motherboard (video card) problem. If the external video is fine, then I would say that you might have a bad LCD screen.

Hi I have a Satellite p35-s605,which has developed a red horizontal line on the display,when connected to an ext monitor there is no line,guess Lcd problem also have reinstaled the os and drivers,

I have a gateway m500 that fell off a desk and crack the LCD. I couldnt use the external monitor so we sent it in for warranty to use the external display. I bought another lcd, put it in, replaced the cables,and now I get color with vertical lines but no picture. Now that I have replaced all of this, my external monitor no longer works. Do you have any ideas on what needs to be replaced next? please let me know. Thank you

I have a Gateway 400SD4. When you first turn on the laptop you can see data on the screen but just for s second then the screen goes white, quite brite too! You cannot see any data on the screen. The external monitor looks great. Any ideas? Thanks!

Have you tested if the laptop works fine with an external screen before you replaced the internal LCD? Disconnect the internal video cable from the motherboard and test it again with an external screen. If you still get the same lines on the external video, even when internal LCD is disconnected, then I would say that’s a bad motherboard (video card if it’s a separate module).

If the external monitor works fine after you disconnect the video cable from the motherboard, connect the cable back and test it again. It might be just a loose connection. If you still have the same bad video, then you might have a bad screen.

It’s hard to guess. First of all, I would check if the video cable on the back of the LCD screen makes a good connection with the screen. I’m not sure if it’s going to help you, but I know that on some Toshiba laptop the same white screen appears when the video cable is not seated properly.

If reseating cables doesn’t help, then it could be either the motherboard or the screen problem. I would say most likely it’s a bad screen but I’m not 100% confident.

Thanks for your response. I took the laptop apart and checked every wire in the cable going to the display and could not find any problems with the cable. Even found there is a fuse on the circuit board but that was OK. I put the unit back together and now it’s working! I think you were right, probably just a loose cable as the connection to the LCD itself does not feel that secure.

I was a laptop technician in a company that only uses Dell, IBM and Compaq. I just recently started my own business in a Flea Market and have come across Toshiba laptops that recently needed screen replacements due to accidents and dc-inline jacks that need to be replaced. Your website is a life saver for a tech that is new to the Toshiba brand. I will continue to contribute what I can as I use your website.

I have a dell 9400 with a wuxga true life display. Recently the video card was changed and then the lcd had a blueish tint and no blacks whatsoever. When plugged into a crt all the colors are fine and the video card works good as well. Dell is sending someone out to replace the motherboard and video card, i was wondering if you have ever run into this problem and the cause…Before the lcd was replaced it was wavy and the windows logo during start up was shadowing.. along with distortions to the color. The wavy ness is pretty much gone but no blacks color distortion and a blue tint remaiins… any ideas? why would they change the motherboard?

I haven’t seen a laptop screen with bluish tint yet, but I’ve seen a reddish tint many times. In most cases, if the reddish tint appears on both screens – internal LCD and external monitor, it’s the system board/video card problem. If the reddish screen appears only on the internal LCD screen but not on the external monitor, then I would suspect the screen itself first. I guess the same would apply to a bluish tint.

I think they are replacing the motherboard just as a precaution. Please, let us know what parts Dell technician will replace and if it fixes the problem.

was supposed to be bringing a Nvidea 7900 go gs. Anyway he changed the motherboard and then later i reinstalled the blue tint video card. ( i had to do it later because he installed the ati x1400 and i had to uninstall it then put back in the nvidea. When i did the blue tint was still there but not on the external monitor. Now this is really wierd. Remember the card i mentioned that was doa? Well i installed that just to see if it would work it did this time… not sure if it will die later on… Here is the thing with that i noticed about the Nvidea Cards today as i was looking at them… The 2 cards that i had 1 was the blueish tint one and the other one was the DOA card each of them had different Assembly Revision Codes on them…The Blue Tint one had A001 (JULY 06)

I was wondering if it had a reaction to the bios of the motherboard.. cause the bios has changed from A01 to A02 when the motherboard was installed…. i dont know i am still lost

They are sending out another card…. Dont know What assbly revisions are only that i BM both cards and the newer (blue tint ) A001 revised card had a 900 score and when i tested the A000 (DOA) had 600 score???

you problem could possibly be the vga cable, or connection of the vga cable. when you check this problem please make sure that your laptop in completely turn off the battery is removed, whit screen is signe of fauly cable or disconnected cable, that is the case if the laptop works on external monitor, else check you video memory. this sort of problem could also couse by dry joint, at mother board chip, or cable connection area.

Thank you for providing all of the laptop lcd tips. I have 2 laptops with pretty much the same issue with a very dim screen or no backlight. Both laptops are fine on external monitor.

The first laptop is an Acer Aspire 3000 that is dim throughout the boot process but a Toshiba M45 has a good screen for about 10 seconds, flickers and then goes dim. I am suspecting both laptops to have a bad FL inverter that needs replacing. Do you have any other suggestions to try? Thanks.

I’ve posted some laptop video troubleshooting tips in this post. Most likely it’s just a failed FL inverter board on both laptops. If Acer Aspire 3000 has a regular lid close switch (not a magnetic one), make sure it’s not stuck and moves freely.

i order inverter board-it light up but the back ground is white, character is black and desk top icon or windows had bad color like low 16 bit color ressolution, the color look like example 2 above but no line. Hook up SVGA work ok.

I have reseated cable hardness from lcd to mothe board so many time. My question is…is it the inverter i have ordered and replaced is bad. I think the invert board is to convert small dc voltage into high RMS voltage to ignite the backligh and control

I recently purchased a toshiba satellite p35-s609 from ebay, my problem is similar to bernie’s in which when booting up there will be a couple red lines on the left side of the screen, while installing windows xp I noticed that there is a reddish hue and diminished color (the white sunburst gradient cirles on the background of the windows turn into reddish circles), this problem is not duplicated on an external monitor. I found that if I tilt the laptop a little will reset the color and brightness to its normal display and stay like that as long as it is kept in that position (which is a little awkward at times). Could this hopefully just be a loose connection from the LCD to the motherboard? I have yet to open it up and wondering what my current options are.

I’ve never seen that FL inverter causes such a problem. You a right, the inverter convert voltage for the backlight bulb, but from my knowledge it cannot affect colors on the screen. I guess you might have a failed video cable, but most likely it’s a bad screen.

BTW, look inside the video connector on the motherboard and video connector on the back of the LCD screen. Check if there are any bent pins. Last week I had to repair Toshiba Satellite P30 with a backlight problem. After 15 minutes of testing I discovered that couple pins inside the connector on the motherboard were bent and the video cable didn’t seat properly. The problem was fixed after I carefully straightened the pins.

In the top navigation bar there is a tab “Laptop Parts”. In there I listed 2-3 companies who sell LCD screens for Toshiba. We worked with Spare Parts Warehouse and AG Parts (used to be ID parts) and don’t have any complaints. Man, screens are expensive.

What does work though is if I leave the lcd screen connected but remove it from the case (so it’s not touching the laptop) the lines go away. Is this a grounding issue. It seems like I am close to fixing it but can’t figure it out…

Hi there. Who wrote this article ? I was wonder what he meant exactly about the 5205 failed board, that ‘failed the microscope utility test’ on the BGA video memory.. What does that mean ? You’ve inspected the ball grid array, and some of those balls were cold soldered ? Why didn’t you just reflow it ?

Satellite 5205 has an onboard graphics controller (integrated into the system board) with a dedicated video memory (external, not shared). You can test the video memory with a utility called “MicroScope”. So I did run the video memory test and it failed. I guess it’s possible to replace the video memory but we do not repair system boards unless it’s something simple like a failed power jack.

Hi! I just got a new laptop: the HP Pavilion DV8333EA and I’m already facing problems! It’s not a major issue but there seems to be a strong pink tint between text on my lcd screen; particularly between vertical characters such as ‘t’, ‘l’ and ‘i’. It’s quite distracting and I didn’t expect such from a brand new laptop. How can I resolve this?

Is your laptop still under warranty? It could be a major issue with the LCD screen or with the video card. A new computer shouldn’t have any pink tint between characters.

Connect an external monitor and turn on the laptop. If you can see the same pink tint on the external monitor, then it could be related to the motherboard (video card). If the external monitor displays characters fine and the problem appears only on the internal LCD screen, then it could be the screen problem.

Test the laptop with an external monitor attached. If the external video as bad as the internal, then it could be the motherboard (or video card) failure. If the external video is fine, and you have a problem only with the internal LCD, then I would check if the video cable got loose. Probably you’ll have to reseat both connections – one on the motherboard and one on the back of the LCD screen. If reseating the cable will not help, probably it’s a hardware issue.

How about this one. Toshiba A105-S2716 Laptop and everything is working fine. Then the screen goes grey with a few white lines running horizontal across it. The external monitor is working fine, and if I cycle through the Fn-F5 key, the LCD starts working again for awhile. Also, if I reboot it starts to work again for awhile. The time it takes to go to the grey screen is intermittent though. It could be 2 minutes or 20. I’m not sure which component may be bad. Thanks for a great site.

Yeah that’s a weird one. I’ve seen a few Satellite 105 laptops with a problem like that. It works fine for 10-15 minutes and then the screen goes gray with a few horizontal white lines.

When I got a Satellite A105 laptop with this problem for the first time it took me just 10 minutes to troubleshoot it. I connected an external monitor and set the video output on both screens. After 10-15 minutes the internal LCD screen failed but the external video was fine. I just ordered a new screen and video cable (as a precaution) because it looked like 100% LCD issue. BUT replacing the screen with video cable DIDN’T fix the problem. The same gray screen appeared after about 10 minutes. Reflashing the BIOS didn’t help either. After that I ordered a new system board and the problem was fixed.

I don’t want you to encourage buying a new system board right away, because in your case it could be just a bad screen. That’s would be nice if you can find a spare LCD screen and test it for a while. But from my experience this kind of failure on Satellite A105 laptops is caused by faulty system board. As I said before, that’s a wired one.

Hi, i have a prob similar to the 1st one that has been discussed. There r lot of horizontal lines that appear on the lcd and the whole display looks inverted and out of focus. Is the problem very common with M55s?

Hi there. I’ve recently inherited an Inspiron 8000 which works perfectly apart from one thing. When the display resolution is set to the lowest setting the windows desktop is off centre, to the bottom right of the screen.When the resolution is set to the highest setting the right and bottom 3 inches of the desktop are off the screen! I have updated bios,drivers,reformatted the hard drive and re-installed windows. Any help would be much appreciated.

Make sure to install a correct video driver. You said that the video is not displayed correctly on the lowest and highest settings, do you have any other settings, something in the middle?

I have installed the latest nvidia driver for the graphics card to no avail. The screen is offset in any resolution. I should mention that the bios and bios splash screen are also off centre. When the laptop is connected to an external monitor everything is fine. I have checked that the graphics card and connectors are all seated correctly.Any other thoughts would be gratefully received.

So it’s not software failure at all, because the screen is off center even before the operating system starts loading. You’ve already updated the BIOS, so it’s not the BIOS issue.

I afraid that it could be either the video card failure or the LCD failure. I cannot narrow it down without test LCD. I don’t think that the video cable can cause such problem.

My notebook’s screen has blue background colour even then it should be black, for example at startup or in DOS command prompt window, so the colours of the screen are distorted. I can send photo to email. External monitor working absolutely OK, even then I replaced the LCD panel the problem persisted. What do you recommend to check?

So you’ve replaced the LCD screen and still have the same problem? Man, that’s was an expensive one, but at least you know that’s not the screen problem.

Have you tried to reseat the video cable on the motherboard? I would try it next. You’ll have to open up the notebook, but you don’t have to buy any part. When you unplug the video cable from the motherboard, take a look inside the connector. Make sure that all pins (if you have any) are straight and not bent. If you still experience the same problem after you reseated the video cable, I would probably replace the cable (it’s much cheaper then the motherboard). The final step would be replacing the motherboard, nothing else left.

I ran DELL diagnostics and it found an error in the display adapter – ie. Intel 82852/82855 Graphics controller. This is ONBOARD video. What can I do??? Is there any way of replacing the chip without the whole motherboard?

If you experience a problem with the video output on the laptop LCD screen but not on the external monitor, then in most cases it would indicate a display related issue. If onboard video card is bad, the same video problem usually appears on both screens, internal and external. It’s not a rule, but from my experience it’s correct most of the time. I think that you have a problem with the LCD screen but after you mentioned this:

Hey thanks for your reply. It’s got me stumped. I changed the inverter and cable and no difference. The diagnostics clearly say that LCD, inverter, cable are all fine. Problem with adaptor…go figure. The most annoying thing is that it was only 1 year and 9 months old when it had this problem. The laptop is absolutely mint condition, I have used it as a ‘desktop’, not even taken it out more than 5 ocassions! If I need a laptop I’m gonna use my girlfriend’s Intel Macbook. Gonna build my own desktop, that way I can fix it easily.

I have an old 5105-S901 which, within a few minutes of running, shows an increasing amount of random pixel trash on the screen – similar to some of your screenshots (both on LCD and external monitor; shows as corrupted ASCII characters during boot-up). In 640×480 (safe mode) it works relatively stable for a while, but it crashes with ‘unknown hardware failure’ within minutes if it’s running in higher resolutions. After spending countless hours of testing, cleaning, replacing memory and experimenting, I found out that it’s a temperature issue with the video card. The Nvidia chip is getting extremely hot (burnt my finger twice) and if I spray liquid ice on it, the pixel trash immediately goes away. The video card has no active cooling, so I guess it became defective from permanent overheating over the years. I’m not quite sure what to do now – I can’t leave the laptop open all the time and spray stuff on it every 5 minutes. A new video card is ridiculously expensive ($350 – Walmart has a complete laptop for that price) and I wonder if and for how long it would solve the problem. I already force the CPU fan to run permantently at 100%, but that doesn’t help the video card. Is there a way to improve the video card’s cooling in my laptop model ? Have others experienced similar problems?

Believe me, you are not along. We’ve seen the same problem with this unit many times before, but usually our customers decline any repair because of unbelievably expensive video card.

I have a used ThinkPad T40. I’ve noticed that if direct sunlight hits the back of the screen (the cover), the screen gets multi-colored lines all over. The couple of times that my roommate left the computer in the sun, the lines would disappear after we’d let it cool down. I can only blame myself for this, but the other day I left the laptop near the window, and the sun attacked it once again. Now it’s been two days and many reboots, and I only get picture (on the top half of the screen) when I first turn the laptop on, then it goes to colored or grey lines. I haven’t found any info on the net about screens overheating in sunlight – but is this possible? Is something permanently fried, or can it be tweaked?

I’ve never ever seen or heard about laptop screen overheating in sunlight. Probably I should sacrifice one of my laptops and leave it in the sun to see if I can reproduce the problem.
