  • Gottlieb System 3 Skips Right to Self-Test

    From Kerry Imming@21:1/5 to All on Fri Dec 13 08:48:02 2024
    I am trying to help with a problem with an Operation Thunder (1992).

    Pressing the TEST button should allow you to select SELF-TEST,
    BOOKKEEPING, or ADJUSTMENTS. Instead, the game skips directly in to
    test mode.

    Isolating/disconnecting the switch matrix did not help so I'm pretty
    sure it's not another game switch causing issues.

    According to PinWiki, access to settings may be blocked by a "tournament board", but that only applies to later System 3 games.

    Any ideas on how to troubleshoot this?

    Thanks John. I'll have him check that out.

    Al I can think of is if the switch matrix I/O is damaged on the board,
    then it could go directly to SELF-TEST...and unplugging the switch
    inputs wouldn't change that.

    Diode Test the Switch Returns to see if any gates are blown.
