What Causes a Line on a TV Screen?
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.
Can You Fix a TV Screen With 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.Loose cables causing a bad connection to the TV. If you’ve moved your TV around at all, this could be the reason you see lines.Other devices you’ve connected to the TV. They may also be having issues of their own or might not be compatible with your TV. In this case, you’ll have to inspect the device instead of the TV.
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.
