OK. The backside of that E-cap board looks pretty bad. Need to remove those two 22Ω resistors. and verify that all the traces have continuity. From one point to the next point. Also need to look over the backside of the other power supply board. Checking for solder bridges , missing or cracked traces and bad solder connections.
Those two " pass "transistors with the little heatsinks will get replaced in one of the service bulletins. But check the solder connections for the ones installed.They run hot and like to unsolder themselves.
Look these bulletins over when you get a chance.
