Note some of the ground symbols are different. Gotta use the right one when measuring.
MOST of the set uses one hot GND. If the set was newer it would
probably use a SMPS and that would add a GND. But with those
the chassis GND is cold.

Ah! Okay, yes, I know about that. That's what I meant when I said the AV input. It's isolated by a optical input chip and then it uses T501 for its power I guess.
I did replace that filter cap, and I can't see any garbage in that circuit.
As far as I can tell, it's not in the video. I can inject and RGB signal into the Jungle IC and completely blank the video signal and the bars are still there
