I have problem with my TZ game. Basically, when I use the plunger and shoot the ball into the scoop, after it pops out of the slot machine scoop if I press both flipper buttons it causes the game to reset (GI goes off, DMD goes off, then it goes back to "Testing...").
I have two LED light mods that light up the scoops that I made myself. I noticed that they can sometimes make a short (the metal wires from the resistor or LED can sometimes touch the metal elements of the playfield, so I covered them with insulating tape). Could this be the reason the game shuts off? I'm guessing something else is up since flippers aren't really related to GI lighting.
