The display was working with garbled info on the top display and the bottom display was working perfectly. I turned the game off and now both displays are off. The 32v is reading at 25volts and the other voltages read slightly lower as well from the transformer. The 5 volt power supply is putting out exactly 5 v D.C. I adjusted accordingly. The connector is jumpered at the transformer for 110v setting as required and I have 120 at the house supply. Does anybody have any info for these system 80b nightmares? I have re pinned every connector related to the display power and data feeds. I have also performed all of the ground mods at the transformer base and the individual boards behind the backglass. All fuses are good. Also I have a new daughter board piggyback installed and the game plays fine with audio and multiball. I tried pulling the starter and the backglass bulb and it didn't make a bit of difference. The game itself plays fine other than the display issue. The display no longer works ?.
