Quoted from pintime:I had the same problem on WHO dunnit followed all the steps the voltages ,bridge rectifiers tested OK .Reseated all connectors and checked all grounds also the under playfield connectors were not fulled seated when i checked them .Dont know if it was one connector or a combination but it plays fine know
Most likely will yield only a temporary fix (if it was a connector).
Of course the best way to rule out connectors & isolate the bad one is to reseat them individually followed by a test with a meter and/or duplicating the reset condition.
Start with the important ones listed chronologically in the guide that import or export power.
Better yet, just follow the guide step by step.
