Hm, yep that's the 4 amp 3.3 volt power supply. Out of curiosity what happens when you plug it in now?
Do you have a volt meter and know how to use it? I'd be really curious to see if the 1 volt power line is up; it feeds off the 12 volt supply line. If that's working and the 3.3 volt short could be cleared you could power the board up with a small bench supply and it might work again. But man that is a serious hack.
Speaking of serious hacks, I have a board coming in with a blown set of 1 volt FETs. I'm going to try powering it off the danger board with jumper wires; technically it might work. Then again the voltage drop might be too much but what the heck?
:-) Keeps me out of trouble.

I just get the red light near the power connector, none of the other LED's light up at the front or back.
I have a multimeter to test with. I just need to know where to test. I haven't had a chance to look at the board layout and see what is what.
I'ts certainly the most tightly packed board I have ever had to look at.
It's not too bad. Grab the schematics by googling for sc-mainboard-1.0, it's a PDF from BFL. Once opened take a look at the board layout. On the opposite side from the power plug (top side) you will see a square hole, then a space, then five more holes. Right by the JTAG port.
Those are the voltage test points. They are:
ground 1-volt 3.3-volts 5.0-volts 12 volts.
All reference to ground. See what you find with the board plugged in.
