The Lois ramp on the mini playfield has stopped registering. I do notice that the other optos that register both outside loop shots have the red led lit, but not the Lois shot.

Could this be a faulty opto? Replacing or switching the best option to check right now?

Totally agree, was hoping for a more simple solution....that mini pf'd is a bugger!

Just want to check but I can just swap the optos (connectors, not the actual optos themselves) where they go into the board on the underneath of the pf'd.

If it works do I presume this is a board problem on the original opto connector? and the flip side is if the opto doesn't it a dead opto?

Ok, so I plugged the Lois connectors into the Brian or Stewie...can't remeber...doesn't matter anyway as it registered. The opto glowed red and recognised the ball passing them.....

Does this mean I have a fault on the board itself?? Looks clean, no real issues that I can see....any help guys?

Yeah, it is removable....only a very small pcb...

Np, it's weird....the board looks very very good....eh...but what do I know....

Thanks for the help guys...had a weird feeling that i need to plug the thing in and try it again...did so and little bugger worked!!

Pull my hair out....all fixed now. Cheers.
