The Emperor is full of hacks (25MC46Z)

[Carmine]

We all like to find that unmolested old set that grandpa kept in the living room, serviced by a friend who did honest skilled work... Well I did pick up one of those sets over Christmas, but this ain't it! (I'll post the other pics soon)

Do keep in mind that before dis-assembly, this TV did produce a reasonable picture, and was operated for an hour... here and there. The CRT was OK, so long as you weren't big on the color blue.



So I've embarked upon fixing this thing while I have the time off work, or at least making it better.



Here are some of the hacks I'm hoping someone here might be able to help me with (I'll attack the stereo section again tomorrow).

Below is a bulging 100 mfd/450v cap that was soldered between the chassis and one of the test points on top of the chassis (actually one terminal to the right of the arrow). I don't know what function it serves because I don't have a schematic, but I've pointed it out in the picture below. There is a silicon rectifier in this same area, if that helps. I rather wonder if this thing was even connected near the end, given the very bad solder job... it just fell off under the weight of the cap itself.



Next photo is below the chassis. Some kind of disc cap with most of the exterior coating flaked off (thus I can't read it's electrical rating). I have a feeling this is not an original part either, because if you look where the arrow is pointing, there is a broken-off spade connector loaded with solder that's just floating off in space.



The next items are not critical (for now)...

Something with red wires has been cut off from this part of the space-command circuitry...?



Nice way to wire-in a replacement tuner motor... I've already fixed this one.



And my own temp-hack repair, a cut-off rubber thumb replacing the fine-tuning belt. Looks like it was just about to break. Since replaced with a neoprene o-ring.
