Regulated 5v supply problem for Mr + Mrs Pacman pinball
I'm getting about 5.4v at the regulated 5v supply test points, and thus the game is not booting. The unregulated 11.9v supply is measuring over 15v. I've replaced the bridge rectifier diodes for the 11.9 supply and installed a rebuild kit for the 5v regulator circuit. No change! What's up???
Power supply board is AS-2518-54 and solenoid/regulator board is AS-2518-22.
