I have a 1984 Mitsubishi CS1984R 20" Stereo TV. It powers on, the channel change display comes up, but It seems I'm not getting any power to the Cathode Ray Tube, and there's no lights on the audio panel. I'm kind of against junking it as this set was working great beforehand.
A possible cause might have been accidentally bumping into the power button a few times rapidly while cleaning, I read this wears on parts of the circuit.
Looking around inside, the service labels were floating around loose, I managed to retrieve one with a plastic ruler and dump the other out. Thankfully one of them gave me the location to all the fuses inside the TV. I can';t get THAT good of a look but it appears they all are unbroken (probably need to discharge the Anode Cap and dig deeper to be sure).
Also on my visual inspection, I see there's a weird spring/fuse-internals looking thing screwed onto a metal heatsink for the HOT just under a large ceramic case resistor. The "spring" is bent and pointing down toward a seemingly corroded hole on the Flyback transformer.

I'm kind of new at working on the old CRT TV side of things, but I feel with the retro things me and the family are into it might be a good idea to learn. Would love to get this thing fixed, the picture on it was amazing enough to use my old Tandy 1000 PC iwth it, even for text mode.
