A relay on the solenoid driver board controls the flippers. See or listen to it pull in during self test and at the start of a game. If it does pull in the contacts in the relay might still be bad. The solder connections on the solenoid driver board and the fuse/rectifier board need to be checked for cracked connections. reflow connections as needed. If the relay doesn't pull in , it's driven by a driver transistor on the board that needs to be checked. If I remember correctly the relay coil voltage is 48v(somewhat uncommon) but still should be available from great plains electronics.
