Well, I would start by asking if there are some typical things to check. I see a lot of mention about the two large capacitors in front of the (main?) transformer - are these usually the main culprits of various failing internal components? Further, how would I check a capacitor to see if it's good or not? I know how to check resistors, but just about everything else in there is a mystery to me. But I'm a sponge - will learn everything I can.

Is it true that I could have swapped in a good stereo, only to be ruining it by running it behind those cap's, if they are in fact bad?

Could the capacitors be contributing to the TV arbitrary blackscreen on/off problem I mentioned earlier?

Since the other unit had good sound, I'm tempted to test its capacitors and compare. But again, there's that how-do-you-check-a-capacitor thing.

Thanks again for any help...
