Have you opened it up yet?
As others have said, start with the fuse, then the bridge rectifier, then the capacitor...
It's possible with the large cap that is in there that the fuse popped before the voltage got high enough to fry other things. But it's pretty dicey...
Be sure to inspect the big capacitor (if it didn't blow). If it is bulging anywhere, it needs to be replaced... It doesn't take a lot of excess voltage to make an electrolytic capacitor explode.
Also, check for burned traces...
