Answer: The most likely cause of horizontal lines on your LED TV screen is a partial failure of the array of transparent LCD pixels that make up the screen.
Each pixel is actually made up of three smaller pixels that emit red, green, and blue light.
If one of these small pixels fails to light up, you’ll see a horizontal line on the screen.
Other possible causes of horizontal lines on your LED TV include:
· A loose connection between the LCD panel and the controller board. Check all of the connections and make sure they’re snug.
· A problem with the controller board itself. This is a much more serious problem that will require professional repair.

How do I get rid of the horizontal line on my LED TV?
Answer:
There are a few potential causes of a horizontal line on an LED TV.
One possibility is that the backlight is not evenly distributing light across the screen, causing a dark line to appear.
Another possibility is that there is something obstructing the view of the LED array, which can cause a bright or dark line to appear on the screen.
Finally, if there are any loose cables or connectors connected to the TV, those could also be causing the problem.
If you’re able to determine what’s causing the horizontal line on your TV, then you can take appropriate steps to fix it.
If it’s due to an obstruction blocking light from getting to the LEDs, then cleaning or replacing the obstruction may fix the issue.

What does it mean when your TV has lines?
Answer: When a TV has lines, it means that the image is not being displayed correctly.
This could be because of a problem with the TV itself, or because of a problem with the source of the image (e.g., a cable box, satellite box, streaming device, etc.).
If you’re seeing lines on your TV screen, try restarting your TV and all of your other devices.
If that doesn’t work, call your cable or satellite company to see if there’s an issue with their service.
If there’s still no fix, you may need to have your TV serviced.
