I have a 1980 Amazing Spider-Man pinball machine where the center 3 Bank of targets is stuck. The reason they are stuck is because the solenoid is constantly energized leaving me to believe that there is a problem with the mainboard. Does anybody have a manual and can tell me which triac I'm looking for?

Left bank reset is A3J4 pin 6.

Strobes for the three targets are on A1J6 pins 1,2,3 and the returns are all on A1J6 pin 11

Hope that helps direct you.

Can’t read chip names from the control board on the soft copy I have here, but will check if it’s better in my hard copy.

Possibly Q61 Q62 pair if it’s the coil driver...solenoid 5? But not clearly marked on schematic as the left bank solenoid. But it maps correctly to the harness diagram (pin 6 is solenoid 5)
