Sighhh...It seems like most of the time I'm working on these things vs playing. Anyway, as the title says, my TZ now has a limp upper right flipper. It flips but barley and not enough to move the ball. All the other flips are strong. I checked the coil, connections, EoS, ect all look good. So, I pulled the fliptronics board and tested the transistors. Transistor Q2 that corresponding with the upper right flipper, tests out at .8 ohms vs the others all test between 4-5. Could this be my culprit? I like how these transistors are nice and big!

Thanks Markmon. I'm have a STTNG I could swap with and I suppose that would be the same as the upper right flipper on it. These transistors look relatively simple to change out so, I may order a couple of them with the plan to replace.

I replaced the Q2 transitor today and that appeared to be the fix. In fact I wonder if the flipper was suffering from power loss for a while because it almost has too much punch now. It slams the ball hard into the camera shot.

I was pleased to have it fixed at the first shot though, feels good.
