I have a Gottlieb Monte Carlo I am trying to get running. After 10-15
seconds of play the machine would lock up, reset, or just generally go nuts.
I have already:
- Checked the voltage at C1 on the CPU - it's good
- Replaced the 500 OHM trim pot on the power supply. The voltage is good - 5
volts.
- Checked the connectors on the power supply. I did not replace them, but
they appear to be OK.
- Checked the ground wires on the transformer in the cabinet and made
certain that they were all connected
After the above efforts, I'm getting 5 volts nice and steady on the MPU. GI
comes on. The score display, sounds, game, etc. is totally out.
The red LED is always on on the sound board. If I disconnect the logic
board, the solenoid fires a ball into the shooter lane, but there is no
sound FX, score, gameplay etc.
If I disconnect the sound board, there is no change in the game.
This is one of my all-time favorite games (I love what I love), so I'd love
to get it going. Any ideas as to what to do next is greatly appreciated!
