Pulled it from a dead Tekken 4 cab. Checked it out, I/O board powered up, DVD drive was powering up and spooling, key was present and in place. So I opened the case and found a 4 pin power connector in the back going to the 246 mobo unhooked. I thought "oh wow, this will be easy" so I plugged it in and powered on. Immediately nasty white smoke started puffing out of it. I cut it off and disassembled the unit. It burned out a component just beyond the 2 VGA outputs, it looks like a small non polarized cap but its got 3 legs. It melted pretty bad.
Any ideas what went wrong here? I couldn't find a TP on board to check the +5 but I was at 5.1-5.2 ish at the jamma I/O so if anything I was low or near par at the board.
