  • S.P.Y. (Special Project Y - Konami) Repair Log

    Symptom: On starting a game some music plays for a few seconds then stops, no sound f/x. During diagnosis the sound died completely, so no sound at all, just a rapid ?ticking? sound from the speaker all the time (even when not playing a game).
    Cure: One dead output on pin 9 of the LS374 at location B13, the rest stuck low. Replaced IC and this restored all the music and sound f/x
