Phillips 58PUS7805/12 No Picture

[Bloopeta]

Phillips 58PUS7805/12, was told it had sound no picture, sometimes picture would come back then go again?

From what I have seen myself, its just blank illuminated screen. Tried unplugging each ribbon cable from Tcon in turn.

When one is unplugged, I get half sceen, clear picture.

With other unplugged, get half screen but with thin horizontal lines

Any ideas? Or is it likely a bad panel?

Try the tape-cut off method.

Try the tape-cut off method.

Any idea which pins from and to please?

Also would that be on the cable that gives the pic with lines when connected?

Can be very tough to get it right, maybe start with 15 pins on one side of the cable of the bad side, then unblock one at a time and see if there's an improvement.

Good video there but also I have seen where you need more than one line blocked, guess it just depends on the short: https://www.youtube.com/watch?v=pfrRhw7-ZII

Can also check the little mlc caps on that bad side panel driver board for shorts or very low ohms.
