while the xbox was on, the fan shorted, but after I fixed that short, the motherboard is still shorted somewhere (from testing continuity from 5v to ground).
Ive checked for solder splashes and stuff, and I can't find the source of the short, but my ohm meter says its shorted, and the PSU just makes a buzzing noise when I try to power it on.
I think that when the fan shorted it may have damaged the the fan's power regulator (or chip, or whatever controls the fan speed), and shorted it out. (but oddly only 5v is shorted, not 12v or 3.3)
Anybody know where this is located, so I can remove it? (and replace it from a broken 1.0)
Thanks. The worlds only battery powered Xbox is nothing without a working mobo!!
