Check the capacitors on the 5volt rail.
They normally pop if the psu is old/er after a power surge.

I see this alot with older 500's, the switch mode psu's just die, they will be working fine, then you turn them off and they don't come back on.
I have yet to see a fuse blow on any of the samsung system PSU's.
Plenty of dead psu's from various systems but no fuses blown I just had the same problem. The switch seems to have beenthe problem. I took the top off, re-seated the cables going to the switch. The copper seems to have been oxidized. Also, I think I may have a bad PSU as well, because half of my phones do not come on.
