& also, Is this display still available new anywhere
Those displays are unlike the bally ones, they dont have any circuitry on the display, so all you need to do is replace the glass, they are available.
Have you tried swapping the display with one of the others, it might not be the display, it might be the master driver.
Hi, yep swapped them around, pretty sure the display is crook, looks to be shorting out & sending the other displays crazy, once unplugged all is good,
