I have a Nitro Ground Shaker that I’m fixing up. The display in the match/credit position lights with all 0’s all the time. It is also a little bit duller than all the other displays. The problem is not in the display itself. I already tried swapping multiple good working displays. Also there is a new Alltek mpu board in the machine. I checked continuity through each wire for credit display. All real good. Tried wiggling wire harness with no change.
Please help!!

What does it do when you run the display test?

Same thing when you run display test.

Are you using 6-digit displays? Can you post a video of what it's doing.

Did look at the mpu connector ?

Continuity Through harness from display to mpu all less than 1 ohm

Fixed! Replaced connector pins on both sides of harness. Works good now. ‍♂️
