Problem - Bally 7 digit score display on player 4 is flickering. Almost like it's strobing brighter and darker throughout the segments.
What I've done already - I reflowed solder on the header pins along with the glass display pins. I've done continuity checks on all associated work. Everything checks out. I've tested the transistors which all fall within .5 to .6 ohms. All the resistors look fine. No burning. I've swapped connectors with the player 3 and it still does the same thing. Also, I've connected player 4's connector to player 3's display and no issues. The problem is isolated to this display. My final thought is that the glass is just shot.
I would appreciate any other suggestions prior to just ordering a new display.
