I've committed a cardinal sin, I messed up. There, the elephant is out of the room. In a rush to get the playfield back into my Williams Comet and play a game, I hooked up the black playfield connector to the white backbox connector, and same with the white playfield connector to the black backbox. They are unfortunately the same size and keyed the same way, but the colors should have tipped me off.

I was able to get some good pointers from this thread -

But the suggestions were pretty general on what I likely broke. The symptoms now of the game are a 'system failure', or 7, on the MPU. Looking at the schematics, I can't figure out what to start replacing. I would appreciate any pointers anyone could offer that has maybe gone through this themselves or for a customer. I have some experience replacing PIA's and would like to give it a try myself first. Here is a link to the schematic -

Thanks in advance!

Thanks for the replies everyone, I really appreciate it. I have some PM's in to those who may be interested in repairing it, but keep the suggestions coming.

A little more information. After hooking them up wrong and turning it on, the right flipper locked on. I quickly turned it off (maybe 3 seconds). I reseated all the connectors and checked the flipper switch before trying again. Same issue, another 3 seconds before shutting it off. I fixed the connectors at that point after kicking myself along with checking all of the fuses, none of which were blown.

OP here. Way back when this happened I eventually sent my boards off to be repaired. I sent my mpu and sound boards to Jerry at game room service. He quoted me one to two hours of labor plus parts. It wasn't to expensive at that time. Figured I would comment here so that people don't have to email me. It worked perfectly after receiving the boards back.
