This is my first NIB pin....Great game...I have had it for a few months. I starting noticing last month when the ball went in the mystery hole one of the pop bumpers would go off twice and it would also show this on the dmd screen too. Now it happens all the time and even if the ball auto loads on start of a game the same pop will go off sometimes.

I looked underneath for a lose wire or connection, Nothing found. During game play all pops and mystery do work and register correctly.

Haven't called stern yet, Anyone have an idea? One fellow pinsider I chat with told me to check the leaf switch in the pop that goes off. Anyone have this issue or an idea ?

Thanks

Will do that tonight. Didn't know I could do that from the bottom, Thought I had to take the pop cap off.

Thanks

Issue finally fixed. Turns out mystery hole scoop switch diode was installed backwards from factory.
