The display on my HG that is supposed to show the credits and ball in play is all zeros. I swapped it with the player 4 display and am getting the same results. I put the game in test mode and it doesn't count up numbers like the other displays, just stays at zero. I did a little searching and found a thread where a guy had a similar problem and they told him to look at I think it was J1 on the MPU board. He jiggled his around and got it to work but I had reset the mpu connectors the other day but it didn't change anything. Should I change out the crimp contacts on the connector for the display next?
