I could use some help with repairing mine as well.
Mine has no picture/no sound.
Right now I am just focusing on trying to get a white dot on the screen..
I have done a cap kit replace on the analog board and I have already bought all the caps for the logic board, as well as new sockets and ICs for the logic board.
I've checked the A/C voltage off the transformer and it is reading about 21VAC across the two red wires on the power switch/volume knob.
I've checked voltages on the wires going to the CRT yoke and I am reading:
Brown wire: 132VDC
Black wire: 0VDC
Gray wire: 0VDC
Blue wire 10.4VDC
White wire: 48.9VDC
I can see a faint orange glow in the yoke of the crt but nothing on the front. no white dot or anything.
I'd love to get mine working as well before I have to just part it out and sell it..
I have scopes, logic probes, multimeters, soldering equipment, and general electronics engineering knowledge but I am clueless about repairing this thing.
Anyone willing to help me out??
