Title: BALLY PRO - ZERO DISPLAY Post by: FOXSSLOTS1 on September 29, 2009, 03:30:27 PM I have several boards that I am trying in a game - all display a ZERO in the top (win?) display - tried doing a saferam clear. Have ram clear chips - tried them (not sure what I have to do - move jumper - hold psuedo coin test) anyway - zero stays - no matter what I do. RESOLVED - bad boards and power supplies.
