Hello I have a Dataeast Simpsons game with rebuilt power suppy and display recapped with the following issue:'

On the lower display only there are two segements (m and i) that are turned on when they shouldn't be for certain characters? When the character scrolls to the left the improperly lite segments travel with the character.

My question is this an issue with the logic on the display board or is it coming from the cpu? Any thoughts are appreciated.

Don

Wanted to update for other's that may run into this issue. Turned out to be the display glass causing the issue replaced the display glass and now working fine.
