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.

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.

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.

Vertical and horizontal lines on the best desktop monitors can ruin the immersive effect from your display, which is especially frustrating if you’ve invested into your monitor, like one of the best curved gaming monitors. To find out how to fix annoying vertical lines or horizontal lines on an external monitor, you’ll first want to test the picture to find out what causes these lines on the computer monitor, whether the problem is from the PC, cable box or another input source, or if the fault is with the monitor, its LCD panel or internal hardware itself. And while on the topic of “vertical” lines, there are vertical monitors that exist to help make certain professions or hobbies more efficient, like coding and streaming.

The first option is to test out the image on your favorite computer screen without any peripherals connected. To do this, disconnect all cable connections and use the remote control or the control panel to disconnect Bluetooth and WiFi, if your external monitor is so equipped. If there are no vertical or horizontal lines on the default picture or menu screen, then the problem is likely due to your PC or input device, or to your cable connections. If the lines still appear, then the issue is likely to be with the external monitor itself.

If the monitor shows lines when not connected to any cables or input method, the problem is likely with the monitor itself. Image issues such as lines can be caused by damaged internal ribbon cables or the LCD panel itself. If this is the case, the repair process will depend on what the hardware problem is, whether you have a flat or curved computer monitor. If you see light leaking on the edges of your monitor screen, you may have blacklight bleed, which you can learn about in our resource content on what is blacklight bleed.

If the lines go away when your external monitor has no input, then you’ll want to look for a connection issue or an issue with your PC or laptop’s graphics drivers, driver settings, or picture settings. Additionally, you may want to check for any input lag issues with your monitor at this time.

Make sure all cables are connected securely. A loose connector can cause various picture issues including gray lines, pink lines or green lines.You may want to unplug your monitor from the input device and check the condition of the ports. You may be able to see if there are any bent or broken pins in the connectors of these input terminals. Double-check the cables if you have two monitors. If you need more organization in your space, consider the best dual monitor mount. Don’t use a paperclip or other metal object to try and clear out a VGA terminal.

A screen resolution adjustment may also help. If the device picture settings are not compatible with the monitor’s native resolution, you may see errors such as lines on the screen. On a windows PC, setting a display resolution or refresh rate that is not supported can damage a monitor.This is more often a risk with older CRT monitors.

Warning: If the device picture settings are not compatible with the monitor’s native resolution, you may see errors such as lines on the screen. On a windows PC, setting a display resolution or refresh rate that is not supported can damage a monitor

I suddenly have a thin black line, probably exactly 1 pixel wide, running vertically from top to bottom on my monitor. Could that be a display card problem is it more likely to be the monitor?

I get this "flickering" line as well. Sometimes it"s faint, sometimes it"s on/off, sometimes it permanent. A reboot or turning monitor on and off helps.

It also moves, that is, it"s not the same line of pixels that gets affected. But it is only on the right side of the monitor, so far. But It appears to be the same few lines that gets affected.

Now, you would think it"s the graphics card, but no. I took my Apple TV 4K and connected it to my monitor with it"s own HDMI cable which is connected to the TV. The line appeared there as well.

It has to be some poor/bad connection to the LCD display and internal components. Or a faulty/cheap capacitor (not flux) of some sort. Perhaps it get"s overloaded after some use time (heat) and it stutters "something", because it"s never at a fresh cold restart, always after some time. I"m not a technical expert FYI.

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.

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.

Watching your mobile screen with those white or black vertical/horizontal lines is annoying. In short, it’s tough to use a phone with these lines appearing on the screen. Typically, this issue is associated with the LCD, caused by a faulty hardware component in your device due to some accidental fall or water damage. Phones with such damages can only be fixed at a phone repair center.

Before you head on to the fixes, let’s make your phone data safe. Sometimes, these lines are irreversible, and even the solutions you’re up to try may be followed by some sort of data loss. Therefore, the first thing you should do is make a backup of important files and apps on your device. Some popular ways for data back in Android devices are via:

If there’re white lines on the screen, this solution may prove effective. A battery cycle is when you charge a mobile to 100% and let it drain to 0% again. Usually, the lines will disappear soon as you charge the battery fully.

If the above methods don’t work, it’s time to try this masterstroke. Using your phone in a safe mode will confirm if the lines are because of some faulty app or software.

Check if the lines are gone! If yes (hopefully), then a third-party app is the culprit. Now uninstall the latest downloaded applications until the issue is gone. OR you should try the Solution:4

Suppose the lines are still visible. Then the issue is most likely due to some hardware failure- and the best option for you is to take your device to a reliable repair center.

When a Samsung TV has a connection or processing problem, you are likely to get vertical lines and ghosting. Besides, when the panel and processing board are poorly connected it may show the error. Also, this may happen if the scalar PCB, T-Con, or Cof -IC is faulty.

When the T-Con board is not working, or the wiring is faulty, it disconnects the TV from the screen. The disconnection makes the screen images follow each other with blurred edges. Also, when there is a poor connection between the panel and the processing board, you will likely see a single vertical line on your Samsung TV.

Besides, a fault in any of the components of your TV screen is likely to cause the problem. For instance, a fault in the scalar PCB, responsible for supplying the pixel data on the motherboard and the T-Con board, is likely to cause the problem. The T-con serves as the timing control card. So, when it is faulty, it means that it may not control the timing of pixels on the screen adequately.

Cof-iC connection problem – if you cannot connect the screen to the other part of the television, it makes it difficult for the screen to get the right pixel information. If the Cof-IC is damaged, you must replace it using the Tab bonding machine and connect the Tv components to the screen.

Loose cables and wires- loose control board cables or even grounding issues are likely to damage the screen. The solution to the problem is to have the loose wire fixed. You may also temporarily fix the problem by tapping on the back. It may stop showing the lines temporarily. However, you may try to troubleshoot the problem and fix the broken wire.

When the T-con board stops working or a loose flat cable connection, it may cause vertical lines to appear on your TV. Also, when the T-Con board is defective and not working, or there is a loose flat cable connection or a damaged T-Con board module, you are likely to end up with vertical-colored lines on your TV screen.

Besides, when the Tv frames rust and spreads to the adjacent flat cable connector, it can cause vertical-colored lines on the screen. Also, when humidity spreads to the flat cable connector, it can make the LED TV rust and result in colored lines on the screen.

The work of the T-Con is to control or synchronize image formation timing. It does this by turning the LED/LCD panel on so as to bring up images. Its shape varies depending on the TV brand. So, when a cable connecting it to the T-Con is not working due to dirt or impurities, or rust, it is likely to result in vertical; colored lines on your TV screen.

When the images on the screen are blurry or follow each other, we call it a ghosting problem. In some cases, when images move too fast, they may get distorted, and you are likely to have clouded effects. But this is likely to happen if the Auto Motion Plus is off.

You may then need to reset the picture setting by pressing the home button and going to locations on the screen. Proceed to choose pictures at the top of your left-hand side and click on the expert setting. Go to the Auto Motion Plus settings, click on it and press enter on the remote control.

Your TV will bring the vertical lines on the screen if it has a processing problem. This may result from a poor connection between the panel and the processing board. Luckily, this is a common problem that you can fix on your own.

In some cases, the vertical lines could result from a faulty component. Here are some components that may have a problem and possible ways of fixing them.

T-Con –a fault in the timing control card makes it difficult for the pixels to appear on time. It results in vertical lines. You can fix the problem by repairing the loose T-con or replacing it with a new one.

Cof-IC- it connects the screen to the other parts of your television. If it is damaged, no pixels will reach the screen. Therefore, you can fix it by replacing the Cof-IC using the tab bonding machine.

Vertical lines or ghosting is a common issue not just in Samsung TVs but also in other brands. It may result from a faulty component or a disconnection. Ensure to troubleshoot the source of the problem before trying to fix it. If it is a defective component, get an expert to replace it.

Your LCD produces specific colors and images by altering the colors of the thousands of tiny pixels in the screen. Three subpixels – colored red, green and blue – make up each pixel, and tiny transistors inside the screen electronically trigger the correct color. Various factors can cause these pixels to become stuck on a particular color, including damage to the screen itself or manufacturing defects. Stuck pixels can appear as single tiny dots on your screen, or as entire green lines on your monitor that run the length of it.

Three components are required to properly display an image on the LCD screen – the graphics card, the monitor and the cables that connect them – and you need to investigate these individually if you"re wondering "why does my monitor have green lines?" A problem with any one of these components could cause undesirable lines, each requiring a different method of repair. Plug a second monitor into your computer to see if the lines appear on the new screen. If they do, the issue originates with the computer"s graphics card.

Examine your video cables for signs of damage or wear, and replace if necessary. Check your monitor"s display settings and change them for optimum performance. Once you"ve ascertained that the issue does indeed lie with the LCD, you can address the stuck pixels accordingly.

Pixels stuck in the “on” position may revert to normal operation with a little pressure, according to Geekflare. Use a small piece of tape to show where the line runs and turn your screen off. Slightly dampen a soft cloth and apply gentle pressure to the stuck pixel line. Don"t press too hard or you may make the problem worse. The idea is to gently flex the screen material and encourage the pixels inside to shift out of the permanent “on” position. Work slowly, applying gentle pressure along the whole line. Turn the screen back on when you"ve finished to see the line"s response. Repeat as necessary until all pixels are back to normal.

Using out-of-date drivers can cause various display issues, and your green line may be evidence of this. Check the driver versions for your graphics card and monitor to ensure you"re using the latest releases. Visit the website of your computer or monitor manufacturer to search for updates for your devices. Keep your operating system updated as well, to encourage proper communication between all components.

Stuck pixels sometime respond to quick cycling of the colors, which essentially works the “kinks” out of the subpixels and allows them to work the way they should. You can find various “pixel fixer” programs online as free downloads, including Jscreen Fix, Undead Pixel and Stuck Pixel Fixer. (See Resources.) These programs cycle your screen through different colors to unstick the stuck pixel line, and can take anywhere from 20 minutes to an hour or more to run. DigitalTrends points out that Jscreen Fix also works on mobile, so if you have a green line on an iPhone screen, you can use this fix.

If your attempts to revive your stuck pixel line are unsuccessful, you may have to seek more professional guidance for a solution. Depending on the age of your monitor or laptop, you can contact the manufacturer or an experienced repair technician for help. Check your warranty, as some manufacturers replace LCDs with more than a few dead pixels within a certain time frame. For those LCDs out of warranty, you"ll have to decide whether repair or replacement is a better option.

TV has vertical colored lines on the screen. This is a common issue with many TVs. Vertical colored lines usually show on a TV screen when the T-Con board is not working properly. Many times this can simply be caused from wiring that is not securely fastened. Other times the T-Con Board itself may be faulty and need to be replaced.

A TV screen that shows vertical colors may be caused from a loose cable wiring, loose board, a control board “grounding” issue, a damaged screen, or a faulty T-Con board. A loose wire or bad T-Con board is explained below.

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 you experience a TV showing colored vertical lines, try gently tapping in different areas on the back of the TV, you may see the vertical colored lines go away completely or they might decrease in intensity. If so, you may simply have a loose wiring cable. This is not a permanent solution, but may prevent the vertical colored lines from showing temporarily. To fix this permanently, you need to troubleshoot the issue and find out which wiring harness may be loose, faulty or damaged.

NOTE: Be sure you do some troubleshooting before you order any new parts. This article is meant for the most common issues concerning vertical colored lines on a TV screen. If you are having similar issues, you may have to troubleshoot a bit more to find the true issue.

All the methods to troubleshoot why your LED LCD TV has vertical colored lines applies to all brands of TVs – The T-Con board functions the same in all Televisions and all the above info can be used on any and all TVs with a malfunctioning T-Con Board.
