When I revived an RCA 8 inch portable a couple years ago I had a lot
Of fun viewing all the waveforms with my oscilloscope. It ended up nearly working like new aside from some "jail bars" I could never track down the cause of. I have also used the oscilloscope to align FM radios with a sweep frequency generator, and countless amounts of audio equipment repairs. TV sets are complex enough that every time I work on one it seems the problems aren't the same, however I do have some background in electronics.
