Hey Guys! I just picked up a Bally Cybernaut yesterday in "non-working" condition. The overall condition of the machine is GREAT but unfortunately I'd rather play it then just stare at it's beauty!!
Here's the issue:
- Game boots up perfectly everytime. Flicker flash followed by ONE flash, 2 second pause and then 6 more flashes for a total of 7 flashes. As far as I know, this means everything on the MPU is working as it should.
- Game then goes into attract mode as it should and the insert lights flash as they should.
- I can add credits using the credit button (microswitch rigged to the coin return button) and that's all good.
- When I press the START button, the drop targets reset and then NOTHING?!!? The game locks up and no coils work and I can't enter the test screen. I have to power cycle it and then it will boot again. Yesterday I had it where it would kick a ball out and the upkicker would fire the ball out of the hole after plunging the ball but now nothing again?!?!
From what I can tell, 99% of the coils work fine in the coil test minus the right sling (even though it will work if i use a ball to activate the switch. Also, it seems that the previous owner may have been fiddling with the plumb bob tilt by attaching a wire to it so it would be inactive. I have removed that wire as I like leaving my tilts in place on my games.
I thought, at first, that it was in a constant state of "tilt" after seeing he was attempting to disable it. When the ball would kick into the shooter lane yesterday, the game acted very similar to what a game would do if tilted. Upkickers and slings would work but flippers were off, etc.
Anyways, I not desperate yet but instead of ripping what little hair I have left out, I figured I'd ask you brilliant Pinside folks!
Thanks a MILLION!
