Does the game work otherwise? In other words do you get three balls, flipper action, pops, kickers and scoring noises, and then the game finishes up and the Game Over light comes on?

If not then something has gone wrong, start with my tips here:

After that post results and you may get some help. Tell us what you did and what the game does in response...

Interesting failure. All the other lights work in the game? Did you try the Lamp Test to check that out?

The displays run off much the same power as the rest of the game, so I'd be looking for loose connections on the plugs on the MPU that feed the displays...try disconnecting all the displays except for the 1st player (power off!) and then turn on and see if it lights up. Note that the first press of the Self Test button is Display Test, they should display all the numbers in sequence on all digits at the same time. If the 1st player doesn't work, then (game off!!) unplug it and try the 2nd player.

What I am trying to find here is that one display could take down all the rest, so we are trying each display separately (and Display Test each) to see if that is the problem.

Check that the proper voltages are present at the displays before going too far - schematics are a big help here. I sell large size copies (22 X 34) or 11X17s that are quite legible by the way...
