Twilight Zone Gumball Entry not working.
Also both opto on horse shoe loop not working. They are right next to magnet on loop.
Led lite on opto board. BUT as I am in test mode, I press on the opto board and it says Gumball Entry opto activated...
I am pulling the board and looking for cold soder?

Also oddly as I turn on game the slot coil fires a few times then stops. So does another coil I can't locate but I think it is the coil involved with the ball lock, top right. Not sure if related or not.

FIXED!
Opto pcb had 2 bad LM339 chips.
Funny that if I touched it with my finger super lightly on the back legs of the chips, in test mode it said I activated the gumball opto, (which is one of the three opto's not working btw)

Also the phantom coil firing at game power turn on went away.
