Re: LG Plasma 50PS11, No picture but still has sound

I measured VZB (tough to tell where to measure) on the zsus board at 112 V. This doesn't match any voltages on the pan sticker.

Would this point to a bad zsus board?...

Re: LG Plasma 50PS11, No picture but still has sound

See attached pics.
1st pic is Ysus VS+
2nd pic is Ysus VA+
3rd pic is a closeup of Y sus power input?
4th pic is Ysus +5V
5th pic is Zsus VS
6th pic is Zsus +5V

Any ideas what I should check to help isolate the issue?
Thanks for the help....

Hello,

Just looking for some diagnostic advice for my 50" LG plasma, since i'm too cheap to buy a new TV.

TV has a lot of hours on it, recently the picture stopped working but the sound still works. I have browsed these forums and some youtube channels and started some diagnostics.

So far I have tried running the board with the Y-Sustain disconnected, upper Y drive disconnected, lower Y drive disconnected and the z sustain board disconnected.

There was no picture in any of these cases and I have power on both sides of the fuse on...
