If that cap is bothering you please remove it from the circuit.

I'm measuring a negative voltage at point TS8-3 and everything to the right of that in the TV's Audio Circuit, everything to the left of that measures normally (or as normally as a still malfunctioning TV can measure) which is the 210V that is supposed to be the 245V B+ Supply which is currently only measuring 210V right now.
