Quoted from DruTheFu:

For example, when I select Lamp 75 "Power Payoff" to test, not only does lamp 75 light up as it should, but lamps 84 (Piano Red) and 85 (Slot Machine) also light up

It looks like "84 Piano Red" is on the same ROW as "74 Power Pay-Off" and on the same COLUMN with "85 Slot Machine"

Maybe the Piano Red socket is mis-wired, or something on the CPU relating to it?

Again, I'm not the expert on this, but others on here are!

I would Definitely invest in the Rottendog Power Driver board. If for no other reason, as a back up while this one gets sent out to be fixed by a professional.

For whatever it's worth, When I purchased my who Dunnit, all the playfield flashers were locked on, but still flashed brighter, when the game called for it. I thought it had major board issues, but soon discovered it was a plug in the wrong spot

The plug connector at J107 for the playfield flashers was accidentally plugged into the J106 spot. Even though the plug is a 6-pin, and J106 spot is a 5-pin male, it was pushed on hanging off the RH side by 1 pin.

Moved the plug to where it needed to be a fixed ALL of them. For whatever it's worth
