i have a kong board that has some weird issues, when you turn the machine on the background music starts to play and is stuck on during attract mode. after 10 minutes or so the board will stop and go to a white screen (same screen as no power to the pcbs).

so i decided to test the nintendo power supply, i am only getting millivolts of dc on every pin for connector p09 and p10.and 13 - 15 volts of ac ripple on all pins in connectors p09 and p10 too....how is the pcb even running the little bit of time it does??
and who sells cap kits for nintendo kong power supplies? and is it hard to get into those power supplies? or just get a switcher?
