I am having a problem with the bottom segment on all the displays. In the master display board schematics, it's segment "d".
On player 1, player 2, and the credit / match, the segment is always on. (In the pictures, please keep in mind player 1 and player 2 look the same, in some pics the backglass blocks view)
On player 3 and player 4, the segment is always off.
I am thinking there is something wrong on the master display board? Based on the symptom, is it possible to identify a certain component or bad IC that would cause this?
