Hi Guys. Just needing some help diagnosing a frustrating problem I’m having with my Star Trek.
While playing a game it occasionally kicks out an extra ball when it shouldn’t and sometimes it thinks a ball has drained even though it’s still in play.
I recently changed the trough optos (reciever and transmitter) but that hasn’t helped the problem.
I’ve been through the head box and checked all plugs are seated properly and there are no blown fuses.
I’m not sure if it’s related-but several of the play field insert LEDs brighten up when the flipper buttons are pressed.
Can somebody please help.

Sometime the trough gets divots in it that can cause problems they sell an insert or get out the old Dremel.

Have you tried wiggling the trough opto plugs while in switch test mode?

Gonna vote for wiggling the trough opto plugs connected to the new boards. Have more then once found a bad ground connector on them and when a flipper or something with a little force goes off the board shuts off and back on quickly causing all kinds of trouble

Thanks for the suggestions- I’ll test it when I’m back (away for Christmas).
All the best for the holidays
