TECH: We decided to replace the last stock board in our CFTBL with a brand new Rottendog A12697-1 MPU. We also replaced the back-up batteries, and did a factory reset on the game. Fired it back up, and now the game will not start. It's set up for free play, and nothing obvious is wrong. Game seems otherwise normal...but the start button doesn't light, and pressing it has no effect. Tried manually adding credits to the game (just in case.) No joy.

I'm not even sure how to begin troubleshooting this problem. Checked all the connectors and reseated them again. Still no job. Any suggestions?

The machine is in attract mode. The start switch does not light up (it did previously). In Switch Test mode, the start switch is not detected when pressed. I have a multimeter and can trace continuity but I'm not sure of the best way to accomplish this. Should I unplug the connector that holds these wires, and measure from the connector back to the button?

I can get into the service menu. Anything else I should check?

Thanks for all the assistance.

The problem turned out to be a connector on another board that lead from a "cabinet switch" that had become disconnected. Once reconnected, the game started right up.

We played the game a few times, and then had to go into another room to do some work. We left the machine on, planning to return to play more games later. A few hours later, we heard three loud "knocks" from the gameroom, similar to the sound of the knocker on a pinball machine. I went in to investigate, and finding nothing amiss decided to play a quick game on CFTBL.

The game will start, but now the flippers don't work at all. Back to the troubleshooting drawing board....
