I am not a pro on this. but if you had a bad diode or windings otherwise shorted I imagine that could destroy your coil and burn the transistor too.
Quoted from pintechev:Parts don’t last forever. And flipper transistors get used a lot. Replace it and play the game. If it goes again quickly, we can debug. You should enjoy the game.
Great advice
I am having a holding issue on myWPC95 flippers occasionally. I am just finishing rebuilding them and will fire them up tomorrow. I suspect it will play better until something else goes wrong.
