    On video you will notice that when start is pressed, there is no startup sound before ball is kicked to shooter lane. Also at ball drain the sound of the bonus countdown is way wrong. Otherwise the playfiled works fine. It is not the sound board either as a known good one I borrowed does the same thing.

    Also the game over sound never occurs.

    Do all the sound channels fire in coil test?

    It sounds like one of the sound solenoid triggers is not working correctly. Remember that the sound triggers comes from the driver board and activates the sound board sound one pulse at a time.
    As a quick test I recommend taking an alligator clip and put one end on the ground strap in the back box and momentarily touch the metal part of the transistors #9 to #13 and listen if all are making a sound when touched. If one dosent trigger a sound, either the transistor itself (TIP102 / TIP 122) or the connection from the driver board to the sound board for said transistor is broken.
