    I have a Demolition Man that has been in good working order until recently. When I try to play the game, it will power up and start the game without issue. After ~10-15 seconds of game play, the power cuts out completely for 5-10 seconds and than comes back on again. Any ideas on what to look at first.

    Is there any battery damage on your MPU?

    No damage on the MPU. Batteries are in remote holder.

    Has a Rottendog MPU and DMD controller boards.

    No visually apparent swelling on any caps.

    I will see if the guide you recommended can steer me to the answer. Thank you.

    Unplug the game. Inside the cabinet by the rear wall. Pull back the rubber boot over the electrical hook up coming into the game. Be sure the lugs are clean and on tight.

    Power cord tight in wall and rear of the game ?

    Check and post all the Driver Board Power Supply voltages first

    I worked through the list in the troubleshooting guide and got to the reseating all the connectors on the boards and it appears like the issue may be gone. I will try again soon with the machine cold again to make sure it isn't a failed thermistor.

    Thanks for the advise all.
