Re: LG 55ub830v - Back Light, Sound but no picture

Hi Yohnsee,
Thanks for the reply! In the other thread someone mentioned swapping the main board resolved the issue similar to this - is it possible the part of the main board has failed so it gives off sound but no picture and if so are there any checks I can do? also if the panel has failed is there much I can do to fix it? does the fact I can get some colours by removing ribbons mean anything at all? Thanks again!

Hi Guys!

I was given an LG 55uf850V by a friend who was told by LG that the panel had failed and would cost far too much to replace (All diagnosed over the phone). Can they really diagnose this so confidently over the phone?

Anyway I took the back off etc and after some googling thought I would swap the tcon due to it's low cost and easy replacement - It arrived yesterday and it made no difference (also replaced the ribbons as the second board came with some).

I have read a thread on here about a similar model tv (55ub850v) and it has a very similar...
