JRChristenson:
I've finally started taking a good look at this machine. It looks like the main board (CPU?) and the power supply board both need to be replaced. My question is this: How likely is it that I will spend $400 + replacing those things and still have a pinball machine that doesn't work?

Any thoughts?

I've done it.  gameplan sharpshooter with burned/corroded mpu.  New mpu and I hoped it would make it all better.  turns out, no.  I'm considering unlooming the entire playfield harness to try to track down shorts. 

replacement boards are no guarantee of anything unless you've done the work to narrow down the problems to the specific board. 

I would get the power working first (giving correct voltages at the board test points), then see what else is going on from there. The other boards need correct power before they can be tested accurately. 

JRChristenson:
I haven't really done anything with this yet except a few minutes here and there. Can anyone tell me what price card this would have had in it?

where are you located? maybe someone is close by and could come over and give you a hand.

MameMaster!:
Rottendog will refund your money if it's not the board.

So far I haven't had to use that = as replacing my Power Board worked for me.

I then sent my old one to coinop cauldron to fix as an extra.
