Sounds like the CPU is not starting/running reliably. I would replace all the IC sockets on the main and voice boards. Those are all single swipe sockets and can wear out after all this time.

Quoted from chad:I think Schwaggs is referring to the cpu on thesound board itself.?
That is what I meant, thanks.
Quoted from RandyW:%
The CPU is working fine, as the game boots and plays. Also, as stated in the first post.. every board was sent off and repaired. I have ordered a new speech board from PinballPCB, but it will likely be a while before it arrives. In the meantime, I will keep chasing down the other issues.
The sound board is it's own computer. The program to run the computer is stored in the ROM chips. If the connection to the ROM chips is flakey, the computer can stop or not start at all.
If you don't want to have the sockets replaced, you can try reseating the ROM chips on the sound and voice boards. Sometimes that improves the connection enough to get the board to run.
