Quoted from ChrisHibler:
I would suspect the TIP-102 for that flippers “hold” power has failed. On the FlipTronics board, diode test each of the TIP-102s, comparing results.

Chris, help me understand the Fliptronics circuit here.

If the TIP-102 for the hold failed open, wouldn't the flipper just drop back down?

Or do both kick and hold transistors stay closed during the hold phase, and with the hold transistor failed, only the kick part of the circuit stays energized, overheating the coil?
