i'm having a problem on my JJP PotC where 3 targets are not registering hits. It doesn't seem to be the physical metal leaf part - i can physically get the two pieces to touch and the switch doesn't register. I can't find any lose connections under the playfield. Am i right that if that was the issue the whole column would be out? (at the moment the other targets on drive 2 eg. the SPOT Gold target, are working fine).
Can anyone suggest what I should try next?
