Hey guys thanks for acceptance too group.
So I currently have a Bally’s Evil Knievel pinball machine that I’m trying to get going again. Originally replaced with new MPU and board was not getting any voltage. I replaced one of the factory connectors that powers board. Once done board now has power. Light Blinks twice quick then another 5x following. Game lights up and makes opening game chimes. My problem now is that when on all of the score and ball in play boards do not show any. Numbers at all( can see dim back lighting in each on screens). Tested voltage at each on the boards and all are getting 5v. If I open door and hit the test button, all the solenoids test fine. But other then that none of the display tests happen. Also when I hit the credit button upon start up the game with make the chimes as if game will start but no balls will be sent or flippers won’t work at this point. Hoping my screen/ display problem is what is holding up game start.
Any info or help would be greatly appreciated. Have checked all voltages at tests points and all fuses and all are what they should
Be. Thank you for any info.
