Capcom released an update to use a "standard" multivoltage display for Pinball Magic. Just like other Capcom games that use this same boardset, it was a small aux power supply board that mounts separately in the backbox, and a simple harness to plug it in. The standard Capcom power supply does not provide the DMD voltages. A good idea (simplified design) but ended up being bad in practice, since all other games used the multi-voltage DMDs.
I have one or two spares of the aux display boards. LMK if you decide to go that route.
