After starting Fathom, there are seven MPU blinks but then this happens:

1. Two, and only two, lamps blink: "In sequence" and "Extra Ball when flashing"
2. The solenoid at the Cave Trap eject hole is activated a couple of times.
3. The game won't reach attract mode and a game can't be started (the two lamps described above continue to blink, but the other lamps remain off).
4. The displays are off, except for "Credits".

I have done diagnostics and then everything seems to work (lamps, solenoids, displays,...). There seems to be a problem with switch 42 but that shouldn't stop the game from starting.

I should mention that the sound isn't working (waiting for parts) but that shouldn't keep the game fram starting.

I would really appreciate advice!

I'm sure you'll get plenty of advice here, but given this era of Bally's, have the plugs and pins on the MPU, Solenoid Driver Board been rebuilt yet? Has the Power supply been rebuilt yet? If not, diagnosing these early Bally's can be like chasing your tail. You could try methodically removing and reseating the plugs on the back box boards to see if anything changes. If things do change it's a good indication the plugs and pins need to be rebuilt. Just my $.02.

Are all the balls (3) in the game and accounted for? The game won't start if there are only 1 or 2 ball(s) present.

Sorry, I meant the game won't start if there are no balls or only 1 ball present.....
