I've had this game for almost 20 years now. I had some of the reset issues at a previous residence due to line voltage issues, but otherwise, it's been a solid machine.
Last night, I went to power it up, and barely got into the boot process before it 'shut off.' Power was still there, could hear the speakers working, but no actual sounds. Turning off and back on, you can hear power being applied, but no "POST beep" and D19, 20 and 21 are off. LED 2 and 3 on the power driver board are off as well.
My voltages on the power/driver board:
TP2: .2 (<--- yeah, makes me sad)
I tried unplugging all ribbon cables from the MPU, no change. I also unplugged/reseated J101, J102, J114 on the power board, and J210 on the MPC, no change.
I found a blown fuse (F113). 5A, 250V. I replaced, and got a short sound out of the speakers, and the fuse blew pretty much instantly. Anyone got an idea of where I should start looking to find the cause? The machine hasn't been moved, and no work has been done on it, excepting my checks after this issue cropped up.
