Hello all, I've had an issue with my Scared Stiff where it would start acting nutty in the middle of a game (serving up multiple balls and generally disregarding the optos). The last time this happened I noticed that the LED on the playfield-mounted 16 opto board was not on when the game was powered up. I re-seated the connectors and that solved the issue. I of course, checked all the connectors involved elsewhere and checked fuses F101 and F109 for power as well. This was a year or so ago.
Fast forward to today, and the game again exhibits the same flaky behavior in the middle of a game. I power cycle the game and get the "Check fuses" error message. I immediately go to the 16 PCB opto board, and the light is again, off. This time, re-seating things and checking fuses does not solve the issue, so I checked for 12v at pins 12+13 at connector J5 on the opto board. There is voltage there (actually read 13.5 volts or so), but no LED.
Did the board crap out?
I am at the limits of my troubleshooting skills here, and would greatly appreciate some guidance as to what to do next!
Thanks very much for looking!
