lcd screen vertical lines free sample

Whether they"re red, green, or blue, vertical lines on a computer monitor aren"t a good sign. Although it could mean your monitor is getting old and may soon need a replacement, it may just be you have a faulty HDMI or DisplayPort cable. Alternatively, it may be your graphics drivers need updating, or you need to restart your monitor or PC.

Vertical lines on a monitor are one of three core problems: the display panel itself is defective, the connection between your computer and the display is faulty, or it"s receiving erroneous information.

There isn"t much you can do about the former unless your monitor is within its warranty period, but the others have some relatively easy fixes which might get rid of the vertical lines on your computer screen.

The first step to getting rid of vertical lines on your monitor is to see if it"s to do with the display itself or some other issue. Open your monitor"s menu system and see if the vertical lines show up even over the top of the menu screen.

If your monitor"s menu isn"t in the right place to test whether the lines are on the screen or to do with the connection, you can also unplug the monitor and see if the lines are still present when it is powered on without anything connected to the display.

The exact cause of the vertical lines on your computer screen will only be apparent if and when you fix it, so it"s best to start trying these examples to see what works.

Update your graphics drivers. If your graphics drivers are outdated, there may be a compatibility issue causing the vertical lines. Update your graphics drivers to see if it resolves the issue.

Try the monitor on another PC. If you can, test the monitor on a different PC. If the lines are still present, the monitor or the cables are to blame and need replacing. However, if you"ve tried all of the above and the lines aren"t there, you may have a problem with your PC itself.

Horizontal lines may indicate overheating, physical damage, or a screen resolution issue. To fix the issue, check the monitor connection and resolution, and remove any magnets nearby. Also, turn the monitor on and off, restart the computer, and connect your computer to a different monitor to test it.

To fix ghosting (screen burn) on a monitor, try shutting down the monitor and leaving it off for 48 hours. Another option: Use an all-white screensaver and let it run on your display for several hours. You can also try a software tool that fixes stuck pixels, such as JScreenFix.

Computer screen, like any component of a computer, may fail to work. Today in this post from MiniTool, the topic – vertical lines on monitor will be discussed. What causes vertical lines on computer monitor? How to troubleshoot this issue? You can get the answers after reading this article.

When using your computer, you may find the monitor or computer screen isn’t working properly, for example, monitor not displaying a full screen that has been talked about in our previous post. Additionally, you may encounter another issue: your computer screen has lines running through it in Windows 10/8/7.

What causes vertical lines on computer monitor? Lines on computer screen can be triggered by various issues including outdated graphics card driver, defective ribbon cables, incorrect video cable connections, damage of the screen, etc.

The main reason for computer vertical lines may be the outdated or incompatible graphics card driver. To fix this issue, it is quite easy and you only need to update the driver.

Incorrect screen resolution setting may result in vertical lines on computer screen in Windows 7/8/10. So you can try adjusting the setting to get rid of the trouble.

As mentioned above, the vertical lines on monitor can be related to the incorrect video cable connection. To fix this issue, you can reconnect the video cable to the screen and check if the lines are gone.

Sometimes lines on monitor may be related to the ribbon cable that connects your laptop’s screen to its motherboard. The cable may be worn out and even crack over time.

Are there vertical lines on monitor in Windows 10/8/7? This post has shown you how to fix the problem. Just try these methods above to troubleshoot it if you are bothered by computer screen lines.

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 that has been existing since iPhone 4, and the color of the lines may vary from red, black, blue, or purple. It could result from physical damage and software problems. Anyway, to solve this problem, you should follow the 8 solutions below, so that you can get rid of the lines while reducing the cost of the repair to the minimum.

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 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 on LCDs when LCD cables become disconnected from the logic board during sudden jolts or a fall. A slightly shifted iPhone screen does not necessarily mean it is damaged; it is just a slight shift.

It might be possible 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.

In some cases, system error will result in vertical lines on the iPhone screen. The easiest solution is Joyoshare UltFix. It is a professional iOS repair tool that provides two modes to repair more than 150 iOS issues. Joyoshare UltFix fully supports iOS 16 and is compatible with almost all models of iPhone, iPad, iPod, and Apple TV.

The strongest advantage of this program is that it is able to repair iOS issues, including the iPhone screen vertical lines, without any data loss. Besides, the software will put your iPhone into Recovery mode with one-click. If the lines on the screen are so thick that it blocks the screen, you can also use the Advanced Mode to restore the iPhone to its normal state.

Some of the info about your iPhone will be displayed on the screen. Make sure all the info is correct and change the wrong parts. Then press 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 clean and returned to its original factory settings. All your data will be lost during this process. 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.

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 a lot 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 should be able to 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 use Joyoshare iOS System Recovery directly, which will not lead to data loss and has a very high success rate. We hope that one of the methods in this article can help you.

Back in April last year, Lionel blogged about a vertical line issue that could potentially affect customers who own 17" Inspiron 9200, 9300, and XPS Gen 2 notebook LCDs.

After engaging our engineering and product group teams, as well as the LCD manufacturer, to investigate and isolate the cause of this issue, we narrowed the problem down to a specific part within a certain date range. During that research, we found that the part may also affect the Inspiron 6000, 8600, Latitude D800, D810, and Precision Mobile Workstation M60 and M70 LCDs. That led to Lionel"s second blog post on the topic.

We"ve taken steps to contact those who may be affected to offer a warranty replacement and also put in place measures to rectify any out of pocket expense incurred by out of warranty customers who replaced the affected screens in the past.

That said, there are other variables that can lead to vertical and horizontal lines on other system types regardless of size or model. Lines on an LCD can appear sporadically, at random places on the screen, and for what appears to be for no reason at all. These lines can be caused by normal LCD failures brought on by a multitude of variables, which I"ll try to cover here. Vertical lines tend to be a more common issue in notebooks, primarily because they are subjected to more wear and tear on a daily basis than a desktop LCD.

The most common cause of these lines is simply a loose connection. As notebook systems are carried around, no matter how careful we try to be, they have a tendency to be bumped, jarred, and even sometimes the heart stopping drop. Though today"s notebooks are designed to better absorb and dissipate small shocks, it can still have adverse affects on the notebook"s internal components. A good bump or series of bumps and random movements can cause the LCD cable to become loose. The connection remains intact, but some breaks in the signal can lead to impurities in the reproduction of the image on the screen. Think of a loosely-fastened garden hose… water will still be directed and outputted through the end of the hose, but some water is lost at the connection. This is easily fixed by tightening the hose. Similarly, the LCD can usually be fixed by simply making sure the connection is secure. (Service manuals for Dell systems can be found here on support.dell.com.)

If these simple fixes don"t seem to work, then we need to look at the actual failure possibilities. Vertical or horizontal lines that don"t disappear after the basic troubleshooting are usually caused by circumstantial failures. The most common type of failure that leads to lines on the display is an open circuit connection between the driver IC (flexible circuit board) and LCD glass. This is usually caused by external stresses (mechanical, thermal, etc…), which causes the flex circuit to detach from the glass. The variables leading to the detachment are wide and are dependant on individual cases. With the amount of travel and various operating environments of a notebook, pinpointing the exact cause can be near impossible, unless of course the problem immediately follows a catastrophic event such as dropping the notebook or prolonged exposure to heat or cold, such as leaving the system in a car.

If you are experiencing any problem with lines on your LCD and your system is not one of the potentially affected units, or in the date range outlined in Lionel"s earlier posts, please contact technical support to troubleshoot and identify possible fixes. See below for details on how to do that.

This problem occurs because of a hardware limitation that is known as "tearing." Tearing is a video artifact in which the top portion of the screen shows a different frame of video than the bottom portion. This is more noticeable during scenes that contain fast motion. There may be a noticeable horizontal line at the point where the two frames meet.

When it is playing video content such as a DVD, the operating system has to synchronize playback with the display redraw rate. The video frame is updated during the vertical blanking interval so that the complete, correct frame will be displayed without any tearing every time that the video card refreshes the monitor.

If you experience noticeable cut lines or tearing, and not only when you play a DVD movie, the display may be configured to a refresh rate that one of your monitors does not support. If this is the case, you can resolve the issue by configuring the display to a refresh rate that is supported by all monitors.

On a modern LCD TV screen, white (or any color) vertical lines appear when the individual “tab bonded” wire connections of the ribbon cable servicing a column of pixels on the LCD display begin to fail. It could also be a loose connection of the ribbon cable between the t-con and display.

Subsequently, question is, why has a line appeared on my TV? When a TV is showing vertical colored lines, a loose wire cable in the TV might be the cause. If you knock on the back of the TV, the vertical colored lines MAY disappear temporarily. This is a sign that a cable is loose or the T-Con board is faulty.

If your flat-screen TV has the dreaded vertical lines, half of the screen has turned darker, the screen is cracked, or the screen is broken, this can be repaired but may cost more than you paid for the complete TV. If your screen is cracked or broken, you can try replacing the Screen, LCD, Plasma, or LED part.

Since you have coloured vertical lines try replacing the tcon board first. (supplier example only). They"re not that expensive and if it is the problem it saves a lot of time as well.

- If the power cord is connected to a surge protector or power switch, remove the cord from that device and connect it directly to the outlet. This is for testing purposes. Removing such devices assists in determining if the light display or the white lines on the LCD are related to the device or the Brother machine.

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.

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 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.

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 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! 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.

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.

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?

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.
