line down lcd screen factory
Vertical lines appearing on LCD screen is very common. Whether the screen belongs to a laptop computer or desktop PC, mobile phone, or even a television, the fault is usually due to the ribbon cable and its connections.
A faulty ribbon cable can cause all sorts of havoc manifesting in bright vertical lines. Sometimes they can be coloured lines such as blue, green, grey, black, and red. The lines can appear thick or thin and on just one-half of the screen. Sometimes the fault will manifest as two vertical white lines. You can even get horizontal lines as well.
If you have lines appearing on the LCD screen, then the first simple thing to check is the seating of the ribbon cable that connects the display panel to the motherboard. Most of the time, the fault is with the poor connection made by the ribbon cable.
One of the most common problems with ribbon cables is oxidation of the contacts. It can happen either on the ribbon cable contacts or on the socket contacts. Manufacturers often use a mix of gold and copper for the electrical contacts, however, if they have not used enough gold, then oxidation occurs over time. This results in a working television or laptop screen suddenly exhibiting lines.
One of the most common faults with laptops is that the ribbon cable connecting to the LCD panel cracks. It typically fails near the hinge area due to flexing in that region, and over time, some of the tracks on the plastic cable breaks. I have seen these types of faults on many laptops. It does not matter whether it is a Lenovo, IBM, Acer, Samsung, Toshiba, or even a MacBook Pro!
This type of fault can also occur on LCD televisions; however, it tends to be on new units, where the box has received an impact during transit from the factory.
I used this same method of troubleshooting to repair an LCD television recently. Modern televisions have a video out socket, and if you feed the signal from that to another monitor, you can check for the quality of the video display. If the external monitor does not show lines, then you know for sure that it is a connection issue. Hence, this method of troubleshooting works for some of the modern televisions as well.
When half of the vertical interlace is missing showing a picture that is broken up vertically, the display appears with vertical lines. This is usually due to a cracked ribbon cable.
Generally, for laptops a replacement cable is always required due to it breaking near the hinge. I had this Dell laptop and replacing the LCD ribbon cable solved the problem. I managed to buy a replacement from Dell for a modest price £6.00. The laptop was just outside the warranty period; however, they still shipped out the cable free of charge. This is the reason why people buy Dell. In my experience Dell tend to stand by their customers and products, and their prices for replacement parts are realistic and down to earth.
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.

Several times, your Android phone screen starts flickering or flashing. In such a situation, the best way to fix the issue is by putting the device into safe mode. This will give you an idea of whether the issue is related to apps or others. And then delete the apps causing problem.
So, above are the methods that will help you resolve vertical lines on phone screen Android.However, in case you lost any of your Android device’s data, use the
Power down the computer and unplug all peripherals. If you are using a laptop, take its battery out by flipping it upside down and sliding the battery release latch. Press and hold the power button for 15 or 20 seconds to clear all residual power from the system. Some of the computer’s power might have been transmitting to the monitor, causing it to short out. Reconnect everything and turn the system back on to see if the lines are gone.
Unplug the monitor from the back of the computer and wait a few seconds until it displays a message “No signal.” If the no signal message also has vertical lines, you know the problem is in the monitor and not in your computer. Press the “Menu” button on the screen and then use the other buttons to browse for a “Factory Settings” mode. Select this mode to reset the monitor to its original settings. If the lines persist, the monitor may have been dropped or exposed to a magnet -- which can’t be fixed.
Reconnect and turn the computer back on. Look for the lines at boot up: if you see lines before Windows loads, the problem is either with the video card, the video connection cable -- whether HDMI or VGA -- or the monitor itself. If the lines only appear in Windows, the problem is a Windows setting -- most likely the refresh rate. Right-click on the Desktop once Windows loads and choose “Screen Resolution.” Click “Advanced Settings,” “Monitor,” and then lower the refresh rate to see if the lines disappear.

Ours is a Sony Bravia that is now over 10 years old. Several months ago we started noticing lines, especially on the left (our left) side of the screen. They’d go away after the tv warmed up. Then we started noticing it was darker on that side of the screen, but again, after the tv warmed up the screen would be normal. Then about two months ago it started getting worse and didn’t ever get completely better, even after the tv warmed up. So I watched some youtube videos that all talked about the ribbon cables becoming loose over time and to apply pressure along the top and see if that made it better, and if so, it was a loose cable and if you put electrical tape or something that would help keep the pressure, it would fix the problem. Hubby pressed along the top and sure enough, when he pressed in one spot on the left side suddenly the picture cleared up. Stayed good for about a week, then problems again, pressed again, fixed again. A week or so later, same problem, but this time when he pressed on it nothing got better.
So I decided to take the cover off and look at it better. As I was pressing on the tops of the ribbon cables that run down from the top of the frame, for a minute it got better but then suddenly there was a wide white vertical line, with a thin green one down the center of it, running down the front of the screen, and it was perfectly aligned with one of the cables. So now I still have the dark side of the screen, and some ghosting, and some lines, but now this bright white streak/line right down the front. Another weird thing is that if the whole screen is bright (like watching a show set in a snowy place) then the darkness even on the left side is basically gone, but if the scene is dark at all, that side is almost black. I don’t know if it means that particular ribbon cable is bad, or if something is loose, if things need to be replaced or what. It’s very frustrating as it’s been a great tv. Hubby wants to just buy a new one, but even if he does I would still like to try and figure out this one as it could then go in another room.
For example, it could signal that the power supply is either failing or faulty. In other cases, it could mean you have not connected the HDMI cable well, or there is a poor connection between the processing board and the panel. But another cause could be the picture does not fit the screen exactly.
When you see black vertical lines on your TV screen, the first step is to identify the primary cause of the problem. Start by testing the picture, check your cable connections, and verify that your external devices are working well.
You can also try changing channels to determine whether the lines appear on all channels. Understand that lines on a TV screen can either be a hardware or software issue.
Ideally, aspect ratio, screen resolution, and horizontal or vertical scan frequencies are settings that affect picture display on most TVs. In this case, refer to the external device’s user manual to adjust the picture format settings.
Your TV software runs the device. An outdated software program can cause many problems like vertical lines, poor picture quality, or failure to install apps.
In some cases, a TV fails to process a combination of image settings you have provided. That can cause many picture errors, including flickering lines on TV. While you can go through all the settings one by one, consider resetting your device.
Sometimes vertical lines on an LCD display could mean a damaged T-Con board. The T-Con or timing control card controls the timing of pixels displayed on the screen. If your T-Con board is faulty, the only solution is to repair or replace it.
If you see Samsung TV vertical black lines on the screen, check whether the lines are permanent or moving. If they are moving, your input source is incorrect. Disconnect and reconnect the video cable or HDMI to check if it resolves the issue.
Thirdly, you may come across a problem with your Samsung Smart TV whereby colored lines appear on the edge of your TV screen. The lines may be black, white, or green along the top, bottom, or side of the screen.
The issue occurs when you have set the picture size of your TV to JustScan or Screen Fit. Samsung calls the lines an Overscan line. If your setting is JustScan, the picture resolution of specific programs will not fill the screen, thus causing the lines.
You can resolve the issue by setting the picture size on your Samsung TV to 16:9. The setting will extend the picture beyond the edges and eliminate the Overscan line.
You can fix a TV screen with lines in different ways. For example, you can change channels to see if the lines appear on all changes, change the input source, check cable connections, or power-cycle your device.

So, why there are green lines on a monitor? Well, several factors might be at play if the displays attached to your PC aren’t operating correctly. It’s conceivable that your adapter or cable connection is the problem. Change the cable if it doesn’t work. If nudging doesn’t work, try another.
Throughout this post, we’ll explain why green lines occur on your display and the best techniques to remedy them. The extra information will be invaluable in fixing all of your monitor’s green lining concerns. It’s time to delve in!
There are a variety of possible causes for horizontal green lines or vertical lines on your computer screen, from outdated video card drivers to damaged ribbon cables and improper video cable connections. To determine whether the problem is software or hardware, you may examine the BIOS settings.
When you see a green line on your computer screen, you should inspect your display for any faults, including all the connectors. There might be a problem with the cable causing the monitor’s color to lose signal.
It would help if you examined the possibility that your computer has been infected with a virus or other malicious software. While this isn’t one of the most prevalent reasons for a green vertical line on the display, it’s still possible.
Faulty graphics drivers might also cause problems with your monitor’s connection to the computer. However, although this is the most common symptom, it may also be seen in the form of green lines on a monitor.
Because Windows 10 does not contain the BIOS, any horizontal or vertical striations on your display problem result from a software problem. If you don’t see any horizontal or vertical lines on your Windows 10 computer screen, this is likely a hardware problem.
It’s possible that your computer’s drivers don’t cause the flickering green lines on your display if they occur immediately after the computer has started up and not on the initial screen while the machine is starting up.
You may also try downloading the drivers from the hardware manufacturer’s website if it doesn’t work. Make sure you’re looking at “Display adapters” (in this case, “NVIDIA GeForce 9800 GTX/9800 GTX+”) and the graphics card’s name.
This is the standard procedure to remove the green lines on the monitor, regardless of whether your motherboard is set to UEFI or a classic BIOS configuration:
The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.
Monitoring a computer’s refresh rate can help identify and correct problems with graphics performance. The monitor’s refresh rate refers to how often the screen updates its image. A slow refresh rate can cause visual artifacts, such as green lines, on the screen.
Collectively, these lines indicate that the monitor is not keeping up with the latest graphics rendering instructions. This can lead to an overall degraded experience when using the computer.
The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.
Knowing your screen resolution, even if you aren’t an engineer or a photographer. You can appreciate your multimedia activities better if you know what you have and what you can do. In Windows 10, you may verify your screen’s native resolution by following these steps:
The resolution may be changed by selecting a different option from the drop-down menu. You should only view content that is compatible with your computer’s capabilities.
Be sure to switch off your display when not in use. A screen saver program and turning off the display when it’s not in use will significantly prolong the monitor’s life.
The green line of death seems to be caused by a hardware problem based on the current symptoms. If you go back in time, you may discover similar problems on non-Apple devices. This problem only appeared on OLED-display phones, to be more exact.
There may be more to the problem with water damage than just a replacement screen, but it’s typically just a matter of getting a new LCD or OLED display.
Due to obsolete GPU drivers, the green lines on a Windows 10 laptop are standard. Using specialist driver update tools, you may repair this problem. One of the most prevalent reasons for this issue is a malfunctioning laptop display.
Your phone’s LCD might be damaged if you don’t mend a cracked screen right away. Damage to the LCD screen might occur if dust penetrates the screen cracks. Your phone’s LCD screen might be damaged if you drop it in water or other liquid.
That’s all about the green lines on the monitor from us. An external display with bothersome vertical lines or horizontal lines may be fixed by testing the image to determine what causes these lines on the computer monitor.
It doesn’t matter whether the computer, cable box, or any other input source is to blame; the monitor, its LCD screen, or internal hardware is to blame.

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.
Investigations into technical problems, including which systems, batches, and date ranges are affected, are rigorous, and we strive for accuracy. Unfortunately, not every technical problem can be traced down to the root cause. But in every case, we try to proceed appropriately and in all fairness to affected customers.
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.
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

We hope that one of the methods in this article can help you.
Pull up your menu display---If the lines show up behind the menu display then more than likely it"s not your main board% (You have sound and picture so I don"t think it"s power board related%)---So let"s look at the T-Con board---
The T-CON board, short for timing control board, is the part of an LCD screen that relays messages between the device"s processor -- it"s brain -- and the display itself. The T-CON board is responsible for synchronizing different parts of the screen with the information it receives from the processor. When the T-CON board fails, the timing between different parts of the board is disrupted, leading to errant lines, both horizontal and vertical, as well as pixelation
In this picture of your T-con board you will have to also clean the 2 upper flex cables to your screen. 1 is vertical the other is horizontal.If this still does not help then it could be screen failure.
