Recapped Power and Sound boards (sound works now), installed new MPU to Driver board connector, reflowed all other connectors, installed new AA batteries (battery holder/MPU free of corrosion), checked/replaced all fuses.
On power up, the 2 MPU LEDs flash twice then go out. GI lights up okay, but game goes into ‘audits’ mode. If I open coin door and off/on a few times I get sounds and displays flash and sometimes a solenoid or two fire, but displays either go on, then off after a few seconds or stay on but game will not register credits.
I swapped out driver board with a known working unit from my FLASH but symptoms are the same.
Any and all suggestions greatly appreciated!
