    The machine turns on and the LED on the MPU module A4 blinks and there is the start up tone. From there all the lights, other than the scores come on. The self test button does nothing. The start button does nothing.

    This unit had the same problem about a year ago. All the fuses were swapped out and it worked for about twenty games or so. In mid play the scores blacked out, the flippers stopped working, the sound stopped, the ball drained and here i am again. I have checked the fuses. They do look good.

    Any suggestions?

    A video of the boot up and state of the game would help. Assuming you are getting 7 flashes on the MPU, but verifying would help. It all starts with power and connectors. I would recommend taking out the solenoid board and reflowing the connectors. Replace the original large filter caps while your at it. Measure all the voltages and confirm they are correct.

    "All the lights come on" - do you mean the controlled lamps are blinking correctly in attract mode? Or do you just mean the general illumination lights?
