Quoted from JadedHesher:

Hey, how goes it ?

I would then take every single fuse in the game (yes all of them, even under the playfield) and literally throw them all out. Then with the help of the manual go and replace them all.

- why? seems like a total waste of money to throw away good parts. If they are the wrong rating of course replace with the correct fuse. but throwing away perfectly good fuses is silly.

Anyway back to the OP. It sounds like a connection issue to me. It could be on the MPU, it could be the socket for the CPU or the ASIC. Or the pin of the ASIC was bent/damaged during the transfer. Could also be an intermittent issue with the CPU chip, as it heats up a leg is losing continuity and things go off the rails from their. Which brand of board did you go with for your replacements for the MPU and Driver board?
