Hi all. Just wanted to pick your brains on how to determine where to go with my haunted house issue. I rebuilt the power supply because I wasn’t getting any voltage to my displays. It took care of the issue, but eventually booting became intermittent, and now rarely boots. I have repinned all of the connectors on the power board, and the connector that goes from the power supply to the main board. I ended up buying a replacement power supply board because they are cheap, and It didn’t change a thing.

When it’s not booting, the flashers work on the backglass, the gi works, some of the inserts light up on the playfields. None of the coils kick on, and there is a 0 on the credit display.

Again, not really sure where to start, so any help is greatly appreciated.
