Thanks for the reply, it made me take a better look. My board had a cap in place of the battery and when i looked really close the cap was starting to leak. Replaced it with a remote battery pack and solved problem.

I think i have this finally completely working. The only issue i know of now is the o and the n in coney light up at the same time. Gotta see what i can find

I have a coney island that the D on the playfield lights that say Island is not working. I thought it was probably the socket so i changed it and no change. I assume this light is controlled on the light board. Short of testing all the transistors is there a listing for the location?
Thanks

Q39 it was. Also traced back to the resistor and it looked like it had been hit by something so I replaced it also and the D is working again! Thanks Slgerber!

Haven’t looked at this thread in a while, i remember how helpful Viperrwk was. Just curious, anybody know what happened to him?
