Little background on the game, super clean, no corrosion, all serial number matching and I've owned for 14 years. All switches tested and confirmed working including the three in the lanes that are need to work for the phantom flippers, the switch, opto and proximity all register fine and multiple times in test mode. Phantom is not disabled in settings, for the heck of it I turned it off and on, and I cleared the Phantom data. I also did a factory reset, went beyond that and pulled the batteries, and I've also tried a completely different MPU board with different chips except the security chip. No credit dot. Proximity boards are fine, and yes, it used to work just can't say how long ago it stopped working.
If you know or don't know the game, by hitting the Phantom targets, it spells out PHANTOM and says on the DMD "Complete for Phantom Flip", but mine says Complete for 500,000" I have read one reference that if it thinks the switches (switch, opto, prox) aren't working, it has to relearn and will reset it self after about 10 plays. Well 15 plays later it's still not working for me and is only awarding 500,000. Stumped.
