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.

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 in 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.

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.

If you find a damaged part, you can either consult a repair service or professional repair technician, or you might want to fix it yourself using an electronics repair kit. Use caution when removing ports, and always unplug a monitor before working on a repair.You may need to consult the owners manuals to see what types of repair tools will be needed.If the cable is faulty, the solution may be just to buy a replacement cable.

That may be the best path if you need to immediately fix your monitor and can’t spend time researching and repairing the damaged part on your own, like if you use your monitor for work like a monitor for video editing.

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.

LED TV or LCD TV Panel Repair - Horizontal Line & Vertical Line or Bar Problem.Walton or PHILIPS 32 inch LED TV Vertical Line with Horizontal line problem, ...

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.

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

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

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.

The only thing bothering me is most forums seem to reference one or two thick black lines going right to left; It seems like every other millimeter is a black line. It flickers a bit, and every now and then, the whole screen freezes, the left side of the screen starts growing vertical lines covering and distorting up to half the screen, and then the whole thing just goes back to a thousand black lines covering the screen.

I"ve tried opening the menu and the lines are over it, leading me to think it is, in fact, the lcd panel. If it"s the LCD Panel, I"ve already priced one out, I just want some confirmation before I make this purchase, as it"s $151. I got the TV free from a friend, and he never got to use it because of this issue (it"s brand new).

UPDATE: I can"t find the display any longer, so I was wondering if I could put a different model, same size LCD panel in the TV and still have it work?
