Whether they appear as thin or thick, black or white, in the center of your screen or along the border, vertical lines on a TV or computer screen certainly interfere with your viewing experience. Unfortunately, these lines may signify a severe technical problem that"s disrupting the signal between the unit"s processor and its liquid-crystal display, or LCD, screen.

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. The only fix is to have the T-CON board replaced, which generally means replacing the whole LCD screen and usually the entire device with it.

TABs, or tape-automated bondings, are an integral part of any LCD monitor. These bondings digitize the information they receive from the processor and send it to the tiny transistors that create the electrical currents that ultimately affect which colors you see on screen. A TAB fault -- also called a TAB failure -- happens when these bondings are damaged or otherwise disconnected from the processor. When this happens, entire rows or columns of pixels go dark because they aren"t receiving any messages from the processor to create their colors. TABs can usually be reattached by a professional TV repair person but over time may become so loose and so repetitively problematic that they may need to be replaced entirely.

Short for low-voltage differential signaling, LVDS cable systems use twisted copper wires to carry high-performance data. This technology is more energy efficient than earlier electrical systems used in LCD products and can reduce the electricity costs to power the unit. However, when the copper wire that makes up the LVDS is compromised, through either a jolting impact or residual damage, it interferes with the signal it transports from the processor to the LCD screen. As with a T-CON board failure, this results in pixelation as well as vertical and horizontal lines on the screen.

While some vertical lines are the result of damage to your screen, other causes have nothing to do with you, your screen or even how you use it. Instead, the lines may be tied to the video source. Anything that interferes with an Internet, cable or satellite signal, such as an improperly aligned satellite dish or a frayed coaxial cable, has the potential to cause picture distortion, including but not limited to lines on the screen and pixel problems. Even the source itself can transmit images with lines on it; for example, a local TV news station that suffers signal interference during a live shot may broadcast images with lines, pixelation or ghosting.

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 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.

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.

Immediately upon initial installation, it had thin colored vertical lines, about 20-30 lines, in a vertical band about ten inches wide, right in the middle of the screen.

It has a very interesting set of white nearly-horizontal lines which appear at its bottom-most part/border. These lines swirl into a vertex at the right one third of the bottom of the black area. These lines are thin and grayish-white.

I have an Asus Eee PC 1000HA netbook, which I"ve been happy with for years. Lately there have been some vertical blue lines in the upper-right quadrant of the display. They don"t show up on screen captures, so they"re clearly hardware rather than software related. They also appear both in Windows XP and Debian GNU/Linux.

I am not very familiar with LCD hardware. Would this be the result of a loose connector, or physical damage to the LCD panel itself, or a timing chip, or what? If I find a junk 1000HA somewhere, could I swap out the panel? I"m not afraid of a screwdriver and I dont mind cracking cases. I did look online for replacment panels, but all the larger suppliers seem to be out. It"s an old system for a netbook and I suspect parts haven"t been made for a while.

3. #Shaking module, if vertical lines disappear or reappear, then it can be judged that the possible cause is COF pin broken, and the crease should be found under the OM microscope.

4. #Press the LCD glass side of the panel, if the vertical lines disappear or reappear, it can be judged that the cause of poor contact, OM checking should be able to find the poor contact.

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.

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.

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:

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.

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.
