Hi- The right flipper on my CFTBL occasionally stays up after releasing the flipper button. So far, I've replaced the coil, coil sleeve, the coil stop, spring and EOS switch. I've also checked and cleaned the flipper button. I've noticed that when the flipper is stuck up, it will not return down with hand pressure. When I turn the power off, it falls right back into place. I could compete a full flipper rebuild by changing the plunger, link and pawl-but the flipper assembly is moving very smoothly so I don't think those parts are causing this issue.Swap left and right flipper button opto boards. If the problem moves to the flipper, then flipper button opto board has an issue. If not bad diode on coil or a problem on the fliptronics board.
Whats next to check? Sound like any specific cause?
thanks!

I disagree on changing the coils. That won't solve the problem the OP is having, and just wastes time I'm afraid.
He has determined the problem is on the Fliptronics Board and I agree
with his procedure and assessment. The Hold transistor for the coil is
most likely defective and needs to be replaced.

I agree the OP wasn't very clear about 'hand pressure' meant in grams/foot-pounds but if the main coil was stuck on he would have
noticed the smoke soon enough...and probably mentioned it.

is the same with a broken diode lead on a flipper coil. Turn game on.
Start a game, push flipper button, it locks on. A transistor issue
would lock on at power up.
LTG : )
Yes, but if the diode was open on the coil it would fry the transistor
and it would never turn off, power off and back on and it would still be shorted. It might well be the LM339, but Id start with the hold
transistor on the chance it has biasing issues...
One thing the OP could try - start a game, and with the flipper not energized try lifting the tip of the flipper up. If it pulls and stays
up I would say, pretty safely, that the hold transistor has shorted. In
many cases the hold coil isn't strong enough to lift the flipper, so
this test - without pushing the flipper button - will test that theory.
