Hope its all fixed. My TSPP starting to get an erection problem too, have to try all this out.

Ironic that your Avatar is a WOZ - still hoping?

different set up john
is it getting stuck and then dropping when the ball hits it or is it standing at attention as soon as the machine is turned on?

if it is getting stuck and then dropping it may just be that there is not enough gap between the flipper bush and the flipper.
try pulling up and pushing down on the flipper ( you want to pull up on the flipper so the shaft that goes through the playfield moves, i don't want you to mimic the movement of the flipper when you press the button when doing this) there should be some movement


there should be enough of a gap between the pawl and the bush to fit a tool that looks like this.


I have found quite a few sterns made after 2002 to have absolutely no gap at all from factory
 
if there is enough movement then mimic the flipper up and down movement,
if it is not moving freely then the flipper plunger may be mushroomed at the end and catching on the sleeve (yellow circle on the right in the photo below)
this photo is of a wpc flipper but the plungers mushroom the same way


if it is going straight up as soon as you turn on the machine then you have a blown mosfet on the driver board

Thanks Andy. I'll give it a fiddle.
