Reviving this rather than starting a new thread. The third display has decided to show a single "1" in the first digit at the start of a single or double player game. If I start a 3 player or 4 player game it correctly displays "0". Since "1" is not a possible score for the first digit I am guessing there is an issue with the display board itself?

I probably should have given a description of the boards. It is running an after market cpu board. I will check connections and interchange the displays to see if the problem follows the display or stays with the player.

Thanks
