Not able to access the full set of front door self test options on a Mr. & Mrs. Pac man.
The self test works for the switched lamps, display, solenoids, switches and game over tune. After the game over tune all displays go blank and no matter how many times I press the self test switch nothing else is presented. Even pressing self test 22 or more times does not restart the machine.
Any assistance appreciated.
Thanks John

Resolved issue: There was the slightest bit of corrosion on the off board battery holder. Replaced and could then access the bookkeeping settings.

Hey Bob, best to replace the battery memory (5101 - U8) with NVRAM!
Battery corrosion kills many a board...
