Ok, looking for some help.
I'm working on a project Joker Poker and I've got most everything running except for the credit display at this point. I have repinned several of the display connectors themselves including A5, and i've repined A1-J2 and A1-J3 completely.
I've tested a new power supply and verified i have 60v, 42v and 4v and 8v at the PS. I even pulled my pi-1/x4 from my Sinbad and tested the JP with that.
I have verified that the credit display itself is working, by testing in one of my other 2 machines.
So not sure what else to check at this point, open to ideas... I'm almost thinking i need to start checking the continuity on every wire going to the A5 display (ugh).
Thanks for any insight!
