Have an asteroids cocktail table as a vocational high school project. Not sure where to start, but here is current status.
1. No image. Red LED lit on monitor card. Also red LED lit on MPU board.
2. No game play without image. There is a buzz/beep when any button in pressed, no other sounds.
3. Checked voltages, and the 36 volt on the power supply reads 18v. These are red wires on the J5 connector. These wires trace to the MPU board, so it is not getting the power it needs?
Bad transformer? Seems like the 2 red wires are low by 1/2 coming out of the transformer. There does not seem to be any damage to the transformer.
Any suggestions?
