Yes, I have got into the plate voltage on a pair of 6146 finals on a small CW transmitter one time. (not fun, rest assured). I have not taken the back off yet, but that was going to be my next step. Try to figure out what was what, if there were reasonable numbers on the chips that look like the audio section google them to see what surfaces. Then take the sig gen and inject audio on the 3.5mm input for a computer using VGA as the video. See if I can see audio on the chip that appears to be the audio amp, if so but see nothing out look and see if it is the chip or associated circuitry. Remember this tv was built back in the time of the puffing caps, remember all those millions of little green electrolytic caps that were put out on the market with the wrong electrolyte? Back in those days I worked with glass container inspectors, the servo amps in those machines were of course full of capacitors little GREEN buggers, and almost all of them had the green plague. I had to replace a life worth of servo amps due to that issue. Those and a Netgear switch we used in those machines had the little green ones across -5vdc in the on board power supply of the switch. I have one setting on my desk here flashing away, they were just swap- ping them out and tossing the old ones, I took some home and swapped out the bad caps and now I have nice gigabit switches. Those were little 8 port ProSafe Gigabit switches the GS108.
Oh yes there are a LOT Of complaints about Westinghouse, I got this TV/mon- itor for $75, It has worked well until now, the video is great, makes a great monitor to use in a training room. Now where is the screw driver I need to remove those back screws....
