no picture on LG 37 inch tv.

[Mikeyboy2007]

Hi guys got a LG 37LH3000 LCD tv which has no picture. Backlights etc kick in no problem but no picture. Fuse on tcon tests fine.

Tcon board part number is 6870C-0247A

Is there any repair that can be done or would it just be a tcon replace ?

discovered this wasnt a T-Con problem. in actual fact it was a panel failure. notices a very thin 1 pixel line of white on the very top of screen moving back and forward, im guessing that was the "No Signal" trying to display.
