HELP.......Flipper stuck up ....

Hello. Sorry to revive such an old thread, but I think it makes sense to have all the flipper stuck tech together...

Please help me. I was putting side blades on my Twilight Zone and when I fired it back up to start a game, the upper left (piano shot) flipper stays energized. I think it is different from the OP, because you have to start a game to get it to stay up, not just power on. Also in coil test all flipper functions work, but the hold test of the upper left does nothing.

By reading this thread I'm taking it is less likely a transistor issue, and more mechanical? I lean that way since I had the playfield gyrating to get the inner artwork on and I may have bumped something. Please see the photo below, but everything seems good to me.

I've got a guys weekend at my house next week and hope to resolve it stat.

Thanks,
Chris

no, when turning the machine off it drops.

^^^^winner!

Thanks so much. Just futzing with the left flipper button/board/blade seems to have fixed it.
