Tonight the set wouldn't start again, there were voltages missing in some places where I knew they should be, poked and prodded, checked Diodes and so on but nothing.
Finally I just took the soldering iron and soldered a lug on a terminal strip that I had poked previously when the set mysteriously started running, sure enough it started running again. The connection on the lug looked fine but maybe it was a cold solder joint somehow, I'll see tomorrow if it'll still run but it worked all evening while I was trying to figure out the video problem.
If I disconnect any of the RGB wires on the CRT socket board that particular color goes away so I know the CRT is responding, the Picture control grounds the Base of a small transistor and that seems to be working OK too.
I'm not sure how the brightness control works just yet.
I just found and bought a factory service manual for this thing on eBay so perhaps when I get that I may be able to figure this out.
I suspect bad caps too but without knowing which ones are in what circuit it could be difficult to figure out, I don't want to go through the expense of shotgunning them right now either, not until I see a picture on this thing.
