After installing a Pascal / Flippp board in a Spider-man I'm restoring, I'm getting every segment lit up very bright only on players 1 and 3 for a few seconds then blowing the onboard fuse (60V). However, displays for players 2 and 4 work perfectly and goes through the typical Flippp startup. If I have only display 1 or 3 connected, it will take longer to blow. If I connect the credits display, it blows almost immediately (all connecting/disconnecting done without the game on).
Per Pascal's FAQ, P1, P3, and credits are connected so it would make sense they are all having the same issue. I inspected and tried to narrow it down to a bad display. Between swapping displays in my other fully working Spider-man and P2/P4, all displays work, except when in P1 or P3. I even swapped the credits display and both work in my other Spider-man. Since I think I've ruled out the displays being the culprit, I'm thinking it has to be a connector. I had already repinned A1J3 and A1J2 as I was having a similar problem with the original boards before upgrading to the Flippp board.
Could it be the connectors for P1/P3/Credit? I have connectors on hand that are the correct size but it looks like the connection is different as those connectors have wires coming in and out of them, I assume since they are daisy chained. There isn't a ton of information out there about repinning these, at least compared to that of repinning the connectors for the boards.
Any thoughts/ideas on what this issue could be? Thank you
