    Default gottlieb system 1 repair Countdown

    I have a countdown No chimes

    On power on.
    Ball kicks out and the solenoid stays on.
    Also the coin door solenoid seems stuck on.

    I have a replacement power supply and driver board.
    My CPU has been repaired.

    Thoughts?

    I assume you have checked resistance on the solenoid?

    Has to be done when desoldered.

    Yes it is good and replaced in case.
    Found a video that shows that the solenoids click after 5 seconds of boot up.
    Mine do not.
    But the game functions normal all except for the kick out.
    When started the ball kicks out but since it is stuck on you cant play.

    Thinking it is the bridge rectifier but not sure.
    Hope to find replacement ones

    OK so in desperation I got the PI-1 CPU replacement board from Flipp
    Great board so far:
    Fixed the outhole kicker problem and game is playable
    BUT....
    My score displays are now doing odd things
    Player 1 & 3 lose first digit
    Players 2 & 4 are losing 2nd digit
    Can put in old CPU board and the displays are working so no damage there.
    Have sent an email to Flipp for help.

    Also I have lost most back glass lights, not sure when that happened.
    Any help from the forums appreciated!
