    I have an f14 that plays fine, but I've lost sounds 1-9 on the sound test. (Basically all voices). I am pretty good with a soldering iron and basic circuits, but I have no idea where to begin here. I have an oscilloscope and a dvm, so I should be equipped enough to test. I just need help. Would anyone please be kind enough to guide me?
    Thanks

    Check your ribbon cable coming off the sound board to the mpu. Also check the audio amps capacitors and Cvsd chip

    Lots of threads on what to check.
