Sigh... This is long.
My old TV, a Thompson-made RCA, was getting on in years and the tube was getting, well, crappy. Picture fuzzy, badly overscanned, etc. So this resulted in a trip to the TV shop. $20 bought me an American-made RCA Colortrak 2000 with the CTC-131 Chassis. It had been abandoned by its owner after having the picture tube (or should I say "kinescope", as RCA still called it then!) changed, and was partly disassembled, though the TV shop man made all the connections for me, not that I could have screwed it up, as everything is keyed in that set anyway. Upon getting it home and assembling it, I discover that it doesn't turn on. When you plug it in, you can hear the caps energize, and the big cap in the power supply does give 167 volts (and big blue sparks if you're careless with your meter!), and there is +5v at the switch (which works), as best as I can tell, it doesn't power up. Some Q+A at Badcaps (read the thread here:
http://www.badcaps.net/forum/showthread.php?t=5048 if you feel like it) seemed to have narrowed it down to either a dead microcontroller or bad solder joints in the control box. Trying with a remote with or without the keypad hooked up did nothing, as did disconnecting the remote sensor and trying the keypad. Anything else I can do here, or is it time to seek out a new Micro for this set?
