And then (we) were on the case! My wife just purchased a Whodunnit and it arrived tonight. It powered up nicely, but we're having a problem. The first time that you activate the right flipper, it sticks in the "up" position and won't come down. If you power down the machine, it comes down immediately.

Tried playing the game in Novice mode to test it more--after about thirty seconds of game play, the flipper will begin firing randomly, and sometimes even return to the down position--only to become stuck "up" again when activated.

We tried reseating connectors on the opto board. No joy. Still waiting on a manual--so thoughts?

Thanks in advance.

Turned out to be a wire that was shorting out near the coil. It's fixed and machine is working well. Anyone know where you can find a "Tony's Palace" plastic? Our machine is missing this one--but otherwise in good shape.

And can someone point me towards nice looking custom instruction cards for this machine?

Glad to be on the case!

TECH:
My newly acquired Who Dunnit pinball machine has a strange problem. It plays fine for game after game, but after any extended period of inactivity, the machine will begin to behave strangely. "Autofire" (ball save) will fire over and over, but flippers won't work at all. When you finally switch off the game to reset, the machine always powers up with the following error message:

Check Fuses F115, F116, and Opto 12V Supply.

Fuse F116, a slow-blow 3 amp fuse is always blown. Replace it and the game functions normally again for awhile---then several games later, same problem again.

I've tried burn-in to induce the failure, but nothing happens.

Any clue where to begin troubleshooting this one?

Thanks in advance.
