    All Right guys, I have an amazing Black Knight here that has no speech, everything else works great all other sounds , game play is flawless, game is near flawless . I’ve reseated the speech roms, all connectors on every board, checked fuses, you name it. What’s next to try a new set of Speech roms? I’ll do It if I have to because this game is well worth it. Attached is a pick of the sound board and the game .

    Was the speech working, but now it isn't--or was it never working to begin with?

    Also, do you have Clay's system 3-7 guides? He has a very good troubleshooting section for the sound/speech boards.

    The speech has never worked since I got it.

    Likely that you have a resistor on the sound board that needs to be cut.

    It's kind of obvious, but did you try turning the potentiometer on the upper left of the speech board? If it's turned all the way in one direction you won't hear speech, just sound.

    Replace all the caps on that board... I always start there...

    All the individual components are in stock

    You think caps could be causing the issue with the speech?
    I adjusted the volume on the board it increases the sound volume but that's it.

    Also I have a firepower as well that works fine...could I swap the sound board over to my black knight without damaging anything to test.

    I've swapped mine, so I'd say yes.

    i misread that only the speech doesn’t work and sound are ok

    #14 4 years ago

    Yeah...sounds are ok.

    Did you do this... (know it’s obvious)

    Update...and things got worse. I was playing the game for days since I got it and all was well except.the speech. But the other day I turned it on and notice a the upper right coil locked burning out the corresponding transistors. So I will replace the transistor and all.the caps on the old power supply before I proceed. I failed to mention that the displays are scrolling which I've ready is an issue with failed caps on the power supply...I wonder if the bad caps may have caused the coil to lock and blow the transistor?

    Any updates on this? My BK doesn't talk either. I swapped the speech board with the one in my Firepower. Both boards seem to work fine in FP with the FP roms. Neither work in BK with the BK ROMs.

    Does anyone know if I put a board in FP with the BK ROMs whether the test will play the BK speech?

    I'm leaning towards new speech ROMs but I don't want to waste money if it might be something else...
