Panasonic tc-63R50N color tv
HOT ok. 106v at Collector.
no HV
no heater.
sound ok.
can change channels + adjust volume.
this set has a separate p/s board using an STR51213.
tested resistance on this ic, no pins shorted.
the chopper is making a squealing noise while turned on.
done the usual, esr caps, checked all the big resistors, transistors.
what should i look at next?
