Whether or not you can fix it depends on the cause
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.
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:
All these issues can be fixed, though it ranges in difficulty.
Here are some things you can try to fix those lines appearing on your TV, starting with the easiest options to try.
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.
Change your TV's settings. This step might work for you if the issue isn't because of damage. First, try switching the TV input from different HDMI ports or AV ports. Doing this can rule out problems with specific inputs.
Run a picture test on your TV. It's a built-in feature on newer TV's which allows you to see if the TV display is corrupted. Doing this may look different depending on your TV, but generally, you can go into the settings and find a support option or just a picture test option.
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.
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.
Connections between TV parts may also get interrupted, causing horizontal lines. Sometimes this may happen on its own, or if the TV was 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.
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.
