I have a fireball classic that had every single scoring display die. The coin and ball number display also died. Every display previously worked, they all just went dead very suddenly. Everything else still works.

I'm still pretty new at all of this stuff so I tried to do the basic stuff like check fuses and all of those were good. I also re-seated every connector. Since every display was previously working and they all died at once, I'm assuming the displays are still good and mayube something on the MPU died? Is that the correct board to be looking at? Or do I need to be troubleshooting something else?

You nailed it right on the head! I didn't realize there was a fuse on that board. Swapped it out and everything is fine! Thank you so much for the help!
