[QUOTE="Ge0, post: 5554488, member: 582277"] Chances are you fried all the power supply primary side MOSFETS (little square things). I'd replace them all even though all do not look burnt. Chances are the others are gone (or **** close to it) too. The intrinsic body diode inside those suckers can't handle much current. The tricky part is replacing them. It's not just a matter of desoldering the leads on one and replacing it with another. The Drain tab is probably soldered to an aluminum clad substrate. This is difficult as hell to desolder the devices from without exceeding their thermal rating. I've done this before VERY carefully with a blow torch. Beyond that there is not much you can do.
