    So when I turn on all digits are bright and crisp but after a few minutes - Display Digits 1,3,5,7 go slightly dimmer on all Player 1,2,3,4 displays.

    Is that something on the Master Display board or the 74154 on the MPU?

    The credit/ball display is 100% all the time...

    Then after a while the displays start to sort of flicker...

    Then after a while longer the displays start losing digits and the controlled Lamps start flickering and losing some lamps too... very weird!

    So something common between the controlled lamps and the displays which can affect stability but yet the game still plays...?

    Replaced the 75154 on the MPU - No difference...
