Hey all,
I'm a newbie to working on pins. I found the awesome pinrepair site and read it top to bottom. My only idea left is to get a new cpu, so wanted some guidance first.
Some quick background. Dad bought dragon as an xmas present back in the 90s. It worked great! No free play mod. He said it was a way for us to save for college (we knew where the key was hidden). Years later I have a game room want to have pinball. It didn't start up... Bad power supply. So, bought a new one. It is now working great, but has two issues.
1. Won't save high score and credits don't decrease. High score showed 444444 on all displays. Voltage to memory chip was good, so I bought a new chip from docent. Put that in tonight, reset memory, still doesn't store. Shows 155555 now.
2. It takes 4-5 off and on cycles to get displays to work. First its black, then ghosting, then works until turned off. I have new cables on order from docent.
Any help or advice would be greatly appreciated!
