replace the fuse with a screw and turn it on, when you see smoke coming its good time to unplug the unit.... the part resonsible for the issue should still be smoking when you look at it :P
Then you know what the part is and you can try finding a replacement... also, it is good idea to check surrounding parts and test them out, otherwise your replacement part will burn again.

Retronerd,

Japan runs on 100v AC. If you were powering it with an EU (230V) -> USA (120V) stepdown transformer that might have led to it's premature death.

When a power supply fails like this it usually means the switching transistor has failed. It often takes with it some surrounding components like the bridge rectifier, driving circuit, etc. Ignore the advice from Tiido, unless you want to start a fire in your Saturn.

fire is always fun :P

I have 1 board with an exploded switching transistor...

Are you serious, that sounds dangerous?

I have a power supply from a PAL unit, someone here was going to buy the CDROM I also have and I was going to just give them the power supply too, but I haven't heard back in awhile.

If anyone wants it, cover the shipping and it's yours.

no, not too serious, as viletim said, you can create a bonfire out of your Saturn...
