Quoted from WoodpilePin:I am honestly not trying to troll, I will submit pictures, the more frustrating thing is there were so many plays on the machine. Pat Powers has indicated that the board could have been a returned board with plays but again they have been so terrible at communicating it has been frustrating.
I will say i think they may reuse PCBs. A friend's Metallica had a flipper transistor go out. When the driver board was removed from the NIB purchased game for the first time ever there was obvious rework already done to the board. A couple of parts had been replaced in the past already as there was flux residue and different date codes on a few things. So either Stern reused a board that had been sent back for service or the game needed things fixed around the time of assembly / initial testing.
I don't think this is necessarily a bad thing. The rework was done pretty well besides they didn't clean up flux residue.
