Hi Pinside,
I have a switch issue with ST:TNG and am hoping you can figure it out because I am out of ideas. The game constantly put balls in the shooter lane. After hours of troubleshooting i found that switches #32 (Under L. Gun Sw.2), #42 (Under L. Lock Sw. 3) and #82 (Rift) all don't work. They are all in the same row #2. All other switches I tested worked just fine including others in row 2. I tried a know good xmit opto (it works with another opto receiver) and and soldiered in a spare receive opto for switch #32 as that was the first switch I saw out so I decided to start there but it didn't make a difference. I re-seated all cables on the cpu board and opto board under the play field with no change. Any ideas on where to start looking?
Thanks,
Brent
