The third display on my Joker Poker has decided to show a "1" in the first digit at start up for one and two player games - I believe this is segment h. If I start a three player game the display shows "0" correctly and scores correctly. I swapped the displays around and the issues stays with the third player so it is not a problem with the display itself. Strange issue that just cropped up.
It has a ni-wumpf mpu and original driver board and power supply.
Thanks for any suggestions.
