I recently bought a broken v1.0 xbox. I tested everything and it is just the PSU that is busted.
After some cleaning, I found what looks like a small burn spot on the underside of the psu.
here are some pics I took to help with my explanation.
Any expert modders know how I can "resurrect" this PSU?
the burn mark doesn't appear to be in any of the solder points - actually it's on the dark green of the circuit board.
It doesn't look like anything serious, but I just don't know what this burn spot affects.
