I have an issue that I haven't been able to verify, but my wife has had it come up twice. She told me that she played a game and the left flipper stuck up and wouldn't go down. I came down to check and everything worked perfect for me. Flipper strength was perfect, just like the other side. I checked the flipper mech and the plunger goes through the sleeve/coil like butter. No restriction at all. I told her to play a game this morning and low and behold, the flipper stuck up again. She says it was when she hit the flipper button, not when the game was turned on or the start button was hit. I'll be looking when I get home from work. I'd guess a stuck end of stroke switch? If it was electrical, I'd guess that it would stick up as soon as turned on and I wouldn't have had been able to play all those games without issue. Any input is appreciated. I'll be home around 1 today.
