This chassis was recapped and reflowed and has worked fine for a while. All the sudden it died. Fuse is good, checked all the solder joints, voltage regulator tests fine, checked the traces. What should I check next?
 
do you have 120V AC going in? are the power wires broken? did one of the plug crimps break? is R103 bad? it's a very simple power supply. most likely you lost a quick disconnect off the isolation transformer or something silly, which I always solder those wires on for this exact reason. the rest of the game is powering up?
