I have someone coming to pick up my Haunted House tomorrow. We decided to play it a couple more times before sending it on it's way. We were playing a three player game and While the ball was on the upper playfield the player 2 display went crazy and everything locked up. I immediately shut it off and restarted it. The game booted correctly, but now the start button, test button and coin up don't work. I replaced Z14 and U4, but no luck. Any help would be greatly appreciated.

BTW. All mods have been done to this machine. The connectors have been rebuilt, the ground mods completed, the upkicker mod, the pbdb mods all have been done. The game has been working flawlessly for a while. Anyone got any ideas?

There are two slam switches in that game that must be CLOSED, otherwise
the game won't start up. These switches are in series. One is located
on the coin door (right under the lock I think). Check it to make sure
it is closed and that the wires are firmly attached.


The other slam switch is in the rolling-tilt ball cage on left wall
inside main cabinet. This one should be closed too and have good wire
connections. When the ball rolls up the cage (toward the back of the
machine), then it should actuate this switch and OPEN the circuit, which
will reboot the machine.

Check both switches to make sure they're closed.
Additionally, check the switch matrix connector coming off the MPU board
in the back (A1J6 I think?) It must be connected securely and connector
pins inside it must be very clean and making good contact with the
board, otherwise this can be the source of the two slam switches not
being "seen" as closed by the MPU, and the game won't start up.

Also another common cause of
the displays showing "000000"'s is if the coin lockout wire (used to prevent
coins from going into cashbox if a problem exists) is probably jammed into the
coin switch blades. This is a common occurance when folks have their game on
money play and then try to trip the coin switch with their fingers. The correct
way to manually activate the coin switch by your finger on a Gottlieb pinball is
to push up on the triangular bit of wire that is very close to the front of the
coin holder, on the bottom-this pushes the coin trip wire down and gives you
your credits. There is a triangular manual push point on all coin units in the
Gottleib pins that used the bladed coin switch assemblies.

I have done the slam switch mod on this machine, so I don't think that is the issue. I also went back and changed z15 with no change. It's not coming up with all 000000's. It boots properly. After about 5 seconds the displays come on, the sound comes on and then the displays alternate between 00000's and 770000.

Sounds like it has reset back to factory settings, which would wipe out all credits to start a game.
 
Why does this stuff always seem to happen the Eve that a game is being sold or traded? I have stories of my own that mirror this!

Hope you get the issue resolved and it's something simple.
 
I think it's resolved. I won't know until tomorrow when the Ni-Wumpf board arrives. The guy that was going to buy it drove 6 hours to get here, so I agreed to order the new board if he wanted to stay over another night at his relatives house. We split the cost of the board and he'll end up with a bullet proof machine when it's all said and done.

Worst feeling ever. This is always when this shit happens. Outside of this particular hobby, only test driving motorcycles, before selling them, seems to be worse!
 
Yep. That was a crappy day. Stayed up all night trying to find the problem. Never did. I ordered the new board and had it overnighted. I met the buyer at the house the next day when the new board arrived. I showed him how to install it and I set it up for him. The game worked perfect. It's down in Corpus Christi now. Kinda miss it.:(

You are a seller's seller. I love these above and beyond stories. Makes me proud of people here at KLOV. Although, you do get 10 demerits for selling the HH! Just sayin.
