You said in an earlier post that you didn't know it was them. And you also add that you noticed an effect which shows that one of these little beasties in that can was OK.
I have wondered in the past if this was some sort of batch problem, as I have a few sets here with the original transistors in and they are OK! Just a thought.
Have you injected a signal at the volume control (Middle pin) and see if you can hear it. Either a signal generator or an I-Pod type thingy will do? The output transistors do tend to fail on these. Easier to change as well.
Prove a fault before you start swapping bits. Don't just rely on hearsay or other people, check for yourself. Oh, and try heating the transistor up. Sometimes works. Or cut the screen lead...

If we've always had that, why is the car boot open? You aren't smuggling in another old TV are you...?
