LG 37LH7000 no image, horizontal lines

[mitsukiso]

i guess that it'a an easy question for you guys
so the TV has no image but several thin horisontal lines (sorry for poor quality of picture). it doesn't show menu or change "image". sound ok
i guess it's a T-Con board issue, just to be sure before buying one. Ribbons and cables are okay, tryed to clean them with rubber and alcohol. Thank you for help!

T-CON Bds don't give horizontal lines when they fail. Your problem here is either a failing Main Bd of failed cables (Main Bd to T-CON Bd) Clean the cables with Isopropyl alcohol and make sure to re-seat them correctly.

Tcon must be tested at least power supply tensions. No one can play at Bingo with only a partial picture..

Change the processor? Mmmh, i think rarely fails it..

The T-CON processor usually gets a little hot. I don't think that is your problem, though.
