The displays decided to start acting up on my meteor. The issue is strange, and I have not encountered it before. Before explaining the issue all connection joints on the displays have been reflowed, and I have moved displays around to see if the issue is display specific.

In attract mode for high score display, the first digit is out on each display. When the high score alternates to "00" in attract mode the third display show "05" and the fourth displays does not light at all. During a game, all displays work properly with the exception of the third display. While scoring points all digits work properly on the third display. However, once the player turn ends the first digit does not light when the current score is displayed.

Am I looking at a MPU problem? It is running an Alltek all-in-one mpu board.

Thank you for the replies. Yes, I forgot to mention all digits display correctly during the display test.

Unplugging one card at a time does not change the behavior.

This morning the displays decided to act a little differently. During attract mode all digits were displayed except for the first digit. When it alternated to "00" only the first display showed "00". All other displays were blank. During game all displays worked correctly except for the third display which exhibited the same behavior as before.

Yes, here is the update.

The pin has an Alltek board. I was having some issues with another pin and pulled the Alltek board from the Meteor and installed it in the problematic pin for troubleshooting purposes. When I reinstalled the Alltek board in the Meteor I began having display issues. I completely cleared the Alltek board - removed battery, did a hard reset - and that resolved the problem. Evidently some of the settings from the other pin did not clear by just resetting the on-board switches. For good measure, I also repinned the connectors from the board.
