The diode on that coil is bad, missing, or broken at one lug.

That's typical behavior for DE when the coil diode has a problem.

No, that's not what I'm saying.

On DE games with the Deger flipper board, if the diode on the flipper coil is broken, you can get the symtoms you describe. Try replacing the diode on the flipper coil.

From here: http://techniek.flipperwinkel.nl/desega/index2.htm#flip0

"Flipper Gets Stuck in the Up Position...
Before proceeding with repair, first determine if the stuck flipper is a mechanical or electrical problem. If the flipper is stuck in the "up" position, turn the game off. Does the flipper return to its normal "down" position? If so, the problem is electrical. Otherwise if the flipper stays up even when the game is turned off, then the problem is mechanical.

Electrical: On Deger (Playboy, Monday Night Football) and solidstate flipper games (Robocop and later), check the flipper coil diode. If the flipper coil diode is broken or shorted on, the flipper coil will stay energized after using it. Replace this diode with a new 1N4004 or 1N4007 diode. The counter EMF (Electro-Motive Force) produced by the magnetic field in the coil collapsing is a reverse polarity voltage. This reverse polarity voltage can cause damage to the flipper board. In most cases, it will gate the SCR (Silicon Controlled Rectifier) in the holding voltage circuit, causing the flipper to remain energized as if the player was holding the cabinet flipper button in. This was mentioned in service bulletin number 58. "
