Another (maybe? hopefully? simple problem on an AFM I would love some help with -
The flasher in the playfield set between the 3 pop bumpers does not work at all. The entire game has LED including flashers. Every other flasher in the game works.
The TIP102 transistor associated with this flasher is Q30 (Jets). When I grounded the tab of the TIP102 with a lead on alligator clips, the flasher lit up. So there is no issue with the bulb or the wiring from the bulb to the board.
I replaced the TIP102 and the flasher is still not working. There are no apparent board defects (solder bridges, scratched traces, burned traces, etc)
The game reports no errors and has no credit dot.
What else could cause the flasher to be INOP if the wiring is good all the way, the bulb is good and the TIP102 is good/brand new?
