OK, I got the Galaga home and started digging around in it... There's power to the monitor and marquee light but everything there's no communication between the boards and anything, no image on the screen, no reaction from coin drops...
Somewhere in the past someone installed a new power switcher where the problem board normally is. I checked power across this and things came back good. I pulled and cleaned the boards as much as I could but nothing changed with the status. I didn't pull the ROMs because they seem pretty stuck. I didn't want to pull too hard and mess things up. The boards look good.
Also, there was another board that came with this that plugs into the main board at the top then the harness plugs into this. Any udea what it is? It didn't show up in the schematics.
Any idea where to go next? Or, anyone want to take this monkey off my back for $250.00?
