Kind of embarrassed, I slipped testing my power supply and the 24v pin shorted out with the pin next to it and now I just get a white screen all the voltages seem to still be there but I thought the 24v just Pierre the coin counter, so anyone have an idea what I could try?

Before that happened I am getting very odd garbage in the screen and after ordering new rom chips and some tweaking it was trying to play music and I could se random sprites and such, I'll post pictures after u find a replacement t power supply or fix mine.
 
i carry the best cap kits for all the original power supplies if you need and fuses. they are all very low esr, high hour, 105c caps and fit perfectly with case size and lead spacing.
 
24V pin @edgeconnector or P4?

If P4, nothing should happen.
If edgeconnector, the pin beside 24V is on one side GND, so the 24V and the 12V off the PSU are dead. If the pin at the other side was shortened the audio-IC MB3712 @6R can be dead.
 
It was on the power supply pins directly, while I have it open I'm going to reflow the solder just in case that was part of the issue.
