    Actually scratch that, I looked at it just now and C49 was very wiggly. I touched the iron to the pads to reflow them and the positive pad on C49 lifted right off. Now I need to figure out where to reroute it to.

    Actually I was only partially correct, the sub board is indeed the reason why there's no CD audio, the main board is the reason for no power, still trying to figure that out though.

    Is this even salvagable? I don't know where I can bypass the positive pad for C49.

    Edit: Okay for future reference, you can connect the positive lead to pin 28 (VCC) on the chip right above it. It's a decoupling cap, and it isn't necessary for the system to function, so unfortunately it's not the problem.

    Wow man that board looks like itís in pretty bad shape, looks like capacitor fluid stains around them pads, probably one of the reasons they lifted up, you cleaning them up with alcohol and cue tips to stop further corrosion ? Also see rust on other parts in that pic, wonder if someone stored the unit in a humid place.

    It's from North Carolina so yeah it probably sat in a humid basement or attic for years. I've been applying some 91% isopropyl alcohol to a toothbrush and scrubbing away at it. It did work very well for a couple years though. It also looks much better in person than it does on camera, for what it's worth.
