Quoted from Alaskanzen:I have a similar and odd issue, perhaps.
Having replaced and testing my optos, and showing them as functioning on the opto board (I have an aftermarket 5 opto board with led indicators) my machine won't register the 'G" drop when engaged. The aftermarket opto board indicates it is functioning but no sound and no register occurs within the game itself. Assuming I don't just have a run of bad optos (I did try two replacements for the G drop target, no change) any thoughts as to what might cause this? Thanks!
5 opto board or 7 opto board
