Gottlieb Countdown - Part 2

I replaced all the boards (power supply, CPU, and driver board) along with the cables form a working Count-down.

The machine boots and everything seems to light up as it should.

However, none of the buttons on the coin door work. I cannot start a game, add credits or even go into maintenance mode.

Any suggestions on how to get to the next step and actually get a game to start (add credits, go into setup mode, start a game, etc.)?

Thanks in advance!

This is a typical symptom of the cabinet switches not registering onto the MPU. Or, damaged chips on the switch matrix on the MPU.

Did you check (and replace if needed) the pins in the J6 connector on the MPU, when you checked the SLAM switch not reporting issue earlier?

Good luck!

The Mpu is new. It is a replacement board (modernized) that was working fine in the other countdown.

Perhaps the wire from the door to the MPU is no good

Thanks for the advice.
