A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color. https://itstillworks.com/causes-horizontal-lines-lcd-panel-37988.html

Hi Paul,
The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.

Hi, possible causes for horizontal line on screen are,

Phone Screen problem and,
The flex of a phone.

When a screen displays horizontal lines on the screen, is when screen of the phone is getting damaged due to phone falling on the ground,or hitting phone on an object can cause horizontal line on a screen.
Solution to this problem is to replace the screen of the phone.



The flex of the phone can also cause horizontal lines on a screen. The flex is a thread like object inside the phone that makes the phone to function properly in terms of the display..

When the flex is getting damaged, it can cause such horizontal line on the screen display.

Solution for this problem,is to replace the flex.
Note : flex can be found only on slide phones.

Thanks for using fixya........

i have a whie line going horizontal all the way across the sceen. how do i get rid of it?

horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.
