Quoted from Gotfrogs:Troubleshooting with JJP identified that one of the drop target coils had burned up.
Bad coil and bad transistor driving it.

Q421 IRL540 Page C-100 and Page D-123 in the manual.

Quoted from Gotfrogs:What does the coil in the picture I posted even do?
Knocks the drop target down.
Quoted from Gotfrogs:is there a way to test the Q421 IRL540 with the coil removed?
Yes. Check Youtube for short videos on how to test a transistor.

Quoted from irishpin:I have a 6 month old RR and the Winkie Target stays down all the time. What should I look for that would cause the target to stay down at all times?
Switch at the bottom of the mech is loose, fell off, or needs adjusting. So the game doesn't know if the drop target is up or down.

Quoted from Gotfrogs:I need to figure out why this is happening.
Not too much to it. Coil shoves it up, coil can knock it down. Be sure that switch is working properly so one of the coils doesn't continue to fire.
Then the transistor that drives it. Be sure it is soldered in good. And check continuity of each leg to a spot on the board away from where the legs are soldered to the board. Losing across or through board continuity can muck up the works. A weak, broken or cracked trace to one of the transistor legs can be hard to see and cause problems.
$80 a coil sounds excessive.
