Troubleshooting a non-working Tron Machine. Just refurbished the cabinet, brought into the game room and it failed to start. Power supply LED flashes on briefly when powering up, hear the monitor power up but no power to the CPU. Verified connections, troubleshot by removing cables and found that when connecting J2 connector on the audio board, the PS LED would remain lite. Pulled the boards and reseating IC chips. Problem still persist. Looking for advice or maybe sending boards our for repair.
