Im wondering if anyone else has ran into this with the xpin 7volution displays.
So my 6 digit displays worked fine, but I was rolling the scores a little easy so I made the game harder by making it harder to score extra balls, but was still able to roll score so I got the xpin 7digit displays. But here is the problem...when hooked up I have lights on the playfield that lock on and others that are off. The connector at J1 on cpu that the xpin boards plug into use some pins for the auxiliary light board. I remove the xpin boards and connect J1 and lights work as the should. I've also changed out the cpu for an Alltek and have the same results. Just to make sure it wasn't my mpu. Seems strange...looking at the back of the xpin boards, you can see where the traces run straight across...pin for pin for pins 11thru19. The ones that I believe are for the auxiliary light board.
I've contacted xpin and they are looking into it, but if anyone here has seen this and could help with any input I'd appreciate it?
