Looking for some help, I emailed Swemmer electronics and getting I reply back.
I had someone reach out to me to help fix their Diamond Lady. They said they had a new MPU installed and everything was working, moved from NY to NC and now game will not boot. There are no manuals for the board and I have never messed with them.
Game will power on and GI comes on, no display lights and the only lights that are sequencing are the 4 or 5 spade insert lights that will blink down the line, but that’s it. All the led lights on the MPU are lite up as if it is working correctly. I checked all connections and reseated all chips and same issue.
Thanks for anyone’s help
