Bought a US Neo Geo last weekend, and discovered the you could use both 110V and 230V
So, i made a 220V plug and turned it on, and there was a flash (blown fuse)
well, discovered a switch i should have moved to 220V (AAAAARH! - well, you learn as long as you live..)

So i did, changed the blown fuse (the one in there was a 250V 3A, the closest i got was a 250V 3.15A - hope that will do????) pluged in the power, and.... nothing..... hmmm
Then there´s this one, is it an automatic fuse of some sort? and can i change it?:

If your monitor and marquee light fixture were also plugged in, then they likely got damaged to. The AC output connectors on the power supply are wired in parallel with the AC power input connector. Thus if you fed the power supply 220, then the monitor and light fixture also got fed 220 volts.

The black "thing" on the back of the power supply box is a 5 amp circuit breaker (push to reset type). That is supposed to trip if something major happens to the power supply and whatever else is plugged into it. Notice I said "supposed to". Things don't always happen that way.

If the power supply is still appearing dead, I would unscrew the circuit board inside the power supply (power disconnected from the wall of course) and flip it over to inspect it. You may have blown off a copper foil trace or two when you fed it 220 volts.
