Third orange cap from the bottom of this row, look at the loose floating trace, damaged or cooked? You may need to repair and mask such traces! verify against a machine of the same revision that it's also going to the correct place.

The PCB need a clean up and any solder showing a void may need a reflow, do not put pressure on any pads or traces, let the solder do the work.

needed more light to see in the keyboard connector and UNDER it.

So fix that stuff up and replace the mylar, make sure your power supply isn't shutting down under full load. That trace under the cap is a problem and needs attention. It's kind of what I expected to find. Trace repair and mask, mylar and clean up and possible 4051's, power supply, then double check your socket legs, pokey, gtia, pia. swapping with know good ones. I suspect with some touch up, trace repair and mylar, as well as power you will be fine though. Never hurts to go the distance.

You either had a short or still have a short by the looks of that trace.
