How to Fix Smart TV Vertical and Horizontal Lines? A complete Guide by Shams Al Sahil UAE
Vertical and Horizontal lines on a TV screen are among the common issue which happens in smart TVs. This issue commonly occurs in LED, LCD, QLED, and Neo QLED TVs. The colors of the lines can be different, black, white, red, or multicolored. These colors define different issue related to TV. The most common issue occurs due to following reason.
Faulty T-Con or Loose Cable
The loose power cable or any other cable may cause this issue. If its due to loose cable unplugging and plugging it again can help to resolve this issue. However, it may happen due to faulty T-Con, a T-Con is the timing controller board, which sends signals from the main board to the panel. If the ribbon connecting the panel and T-Con becomes loose, damaged or corroded then possibly there will be a single or multiple vertical lines appearing on TV screen. Surprisingly these lines may disappear after a time but it doesn’t mean the issue is resolved it may come up anytime again.
These types of issue’s are mostly found in Samsung, Sony, LG, Hisense, and TCL smart TV’s
COF / Tab Bond Problem
Every LED/LCD panel has a tiny chip-on film know as COF which controls the pixels. These can get loose, overheated or damaged due to aging. These lines may be permanent or disappear and reappear over time. Lines may run from top to end. This issue is serious and is considered as panel-level damaged.
Board Failure
If there is an issue with the board, it may be due to short circuit, overheating, faulty IC or moisture exposure. Such damage can cause multi colored lines or lines covering half screen of the TV.
Liquid Damage
It may occur due to high moisture levels, cleaning sprays, or using an indoor tv for outdoor purposes. The liquid damage can burn panel circuit and cause vertical lines that maybe colored or black one or sometimes flickering lines that will appear and disappear continuously.
Software Issue
This is rare but can be cause by a firmware bug that may generate a vertical line on screen. These lines disappear as soon as the TV is restarted. It may appear again after sometime. Updating the software can resolve this issue.
