I've been working on an Atari Airborne Avenger. The score display board wasn't showing the 90 volts that it needs. I discovered that the B4 and A4 chips were both bad and pulling the voltage down. I replaced those chips and the voltage looked good. However, when I plug the display in to the board, those same chips fried again. Can a display cause this or must there be something else wrong with the board?

I hope you're not unplugging/plugging them in with the power on. That's a sure way to fry things!

Nope.
