Hi all. I recently bought my first pin, TSPP (though I had an old EM game at my parents house growing up). I am having a problem with both upper right flippers. The lower right flipper always works perfectly, but about 5% of the time the upper 2 right flippers don't trigger or trigger on a delay. Both the upper right flipper on the main playfield and the right flipper on the upper playfield move together always though - meaning when the upper right flipper on the main playfield doesn't go, neither does the upper playfield flipper. They are always synchonized exactly. I've check all the connections and nothing seemed loose. Any suggestions for what the issue might be? Thanks in advance.
