So a while ago I got a Macintosh LC, power supply was dead but in the meantime I was able to get it working by connecting it to an ATX power supply. It had no sound but otherwise seemed to work fine. Obviously the capacitors were at fault there, so I got new capacitors and set to work...
... except now the damn thing won't work anymore. I checked my capacitors a billion times, they're installed correctly and the soldering is good. I cleaned the motherboard as much as I could. Still nothing.
Actually it's outputting a video signal at the correct resolution, but that's about it. The screen stays black, no audio, no sign of life.
I'm thinking of checking and redoing my capacitors one by one incase something got stuck under one and is shorting things... but first want to see if I can save myself that trouble. Also, should I also replace C9? On my board it's a big 2200µF capacitor, and it looks good (no leaking gunk, no bulging), so I didn't replace it. Could that be wrecking havoc?
