    **EDIT: Added another prize as some felt my original package was underwhelming (My wife said my package was "fine" but I was disappointed with the tone she used). Added a metal novelty sign for the winner. See pic.**

    My F-14 started acting oddly all at once. The left lane save kickback coil would start firing like a jackrabbit on a date for no apparent reason, and stop just as quickly. Soon into the game, the upper VUK wouldn't fire the ball into the lock, and then two balls would be loaded into the shooter lane, rendering the game unplayable. Turn game off and back on, and in attract mode whenever the game fired up sound and the topper, the ball save coil would fire again like a desperate red head swiping right on Tinder. I looked high and low for shorts and re-seated cables/connectors to no avail. And as these coils were not in the same row or column, I was baffled.

    Eventually, I found the culprit. Do you have a guess?

    First one to correctly post the answer wins the prize. If no one does, the closest guess will win.

    Grand prize is: 2 BRAND NEW Solo Cups (red in color), 4 gently used 555 bulbs, and a piece of string (manufacture and length unknown)

    Good luck, and remember... H.I.O.P (Hey, it's only pinball)

    A/C relay for solenoid bank select?

    No, but thanks for playing! Unfortunately I can't afford a consolation prize... I have pinball machines

    Loose screw fell behind circuit board.

    Quoted from chad:

    Loose screw fell behind circuit board.

    My wife did find a few screws loose, but that was me. Not the pin. Thanks for your guess!

    #7 45 days ago
    Quoted from bluebomber:

    "I'm sure it just needs a fuse"

    That was going to be my selling point if I couldn't figure it out

    Transistor on a coil or switch?

    #9 45 days ago

    Nice prizes, but I am stumped.

    #10 45 days ago
    Quoted from 2manypins:

    Transistor on a coil or switch?

    Ah, dude... so close. But no. Maybe you have too many pins.

    #11 45 days ago

    Did I mention the Solo Cups are dimple free??

    #12 45 days ago

    My guess is that you had a switch matrix wire wire coming into contact with either your GI string or the light matrix. This was sending false closures the the MPU, triggering coils.

    #13 45 days ago

    Short to ground somewhere on the driver board

    #14 45 days ago

    Left a tool that shorted stuff out.

    #15 45 days ago

    All great guesses. Obviously you all have experience with some crazy shit.

    But no....

    Thanks for playing. Vanna please show them the door.

    Loose/bad ribbon cable?

    Bad / broken diode?

    #17 45 days ago
    Quoted from erak:

    "and re-seated cables/connectors to no avail"

    Good day... I SAID GOOD DAY.

    But thanks for the guess

    Loose CPU or game ROM chip.

    #21 44 days ago

    diode reversed on the upper vuk switch

    #22 44 days ago
    Quoted from GRUMPY:

    Loose CPU or game ROM chip.

    Ugh. That reminds me of the No Fear I had...the ASIC socket was cracked. I missed it, and my wife found it. Replaced that sucker and it was great after that, but that was some fun soldering times..

    #23 44 days ago

    Power supply capacitors....

    #24 44 days ago

    Awe, shit Morty. They are trying so hard.

    But NOPE suckers.

    Thanks for playing!

    #25 44 days ago

    You replaced a flipper coil and a drop of solder fell on the large diode board on the bottom of the playfield causing havoc.

    #26 44 days ago
    Quoted from pinballplusMN:

    I wish... that would have been an easy find. But Wrong!!

    NO SOUP FOR YOU!!!

    Thanks for playing

    #27 44 days ago

    Too many balls?

    #28 44 days ago

    solder splash on a switch....

    #29 44 days ago

    This game has 4 balls... already 2 too many. So no.

    No solder drips.

    The reason was so damn stupid... but the symptoms were so weird.

    Keep guessing!!!

    #30 44 days ago

    A literal bug in the machine

    #31 44 days ago
    Quoted from TreyBo69:

    A literal bug in the machine

    Gremlin is the accepted term in my f**ked up mind.

    But, no.

    Thanks for playing.

    Keep the line moving.

    Got a mouse in there ( under the cups now)

    #33 44 days ago
    Quoted from rvdv:

    Got a mouse in there ( under the cups now)

    If the mouse was under my cup now, it would be pretty fucked up.

    It's happy hour in Hudsonville.

    But no.

    Thanks for playing, get your parking ticket validated on your way out.

    One of the wires in switch came unsoldered or if ball trough has led switch it was out?

    #35 44 days ago

    Did this start happening on its own or had the game been worked on just recently?

    If no recent work done, battery acid damage on driver board causing switch matrix confusion or a cracked diode lead on a switch or flipper coil.

    If recent work done, diode installed backwards

    #36 44 days ago
    Quoted from holminone:

    Getting closer, but NO!

    Thanks for the response

    Broken spring in a coil?

    #40 44 days ago
    Quoted from guss:

    Hahaha... best answer yet, and very close.

    But unfortunately no.

    #41 44 days ago
    Quoted from holminone:

    Getting closer, but no.

    C'mon... who wants those bitchin Solo cups?? That is like a $0.49 value.

    Gawd....

    Broken ball trough switch actuator broke off and found its way over to the kickback rollover switch.

    #43 44 days ago
    Quoted from mikat11:

    Broken ball trough switch actuator broke off and found its way over to the kickback rollover switch.

    That sounds fricken cool... but no.

    You guys have seen some shit, I gotta give it to you.

    But this was not that.

    Shorted flasher?

    #48 44 days ago
    Quoted from EasternBloc:

    Benthic monkfish lay an egg in the VUK again?

    It didn't smell like fish, and I checked my fingers to be certain...

    Quoted from ryan1234:
