I have this SNES jr that will only load a game up occasionally and when it does, it only stays on for about 20 seconds before resetting to a blank screen. I have cleaned the cartridge port, av connection is good, power is fine, fuse not blown, and as far as I can tell, the 7805 is ok. Would a faulty capacitor cause this sort of problem? They all look fine but I don't have a way to test them properly.
