Have a tekken 4 that works great but no sound. I have adjusted the knob hav gone into test menu. If I cross the red/white audio wirers I hear hum from speaker.
Any help would be very appreciated.
Thanks
 
I don't know a remedy but maybe something to try is replace the red/white rca wires with a different set and see if that makes a difference? I've had rca wires go bad on me before.. it's something that just happens.
 
Thanks but no luck. I tried also hookin the audio wires directly to my tv and no luck either. Has anybody else run into this before?
 
Maybe the volume potentimeter on the I/O board is busted? You have another I/O to try or someone in your area that has one?
 
If I hold the red n white together and adjust the knob I hear the hum change pitch so I think that's working. I also bypassed the I/o n hooked to my tv but no luck but also not sureif that would work.
 
any update?

i also have a tekken 4 machine with no sound, have you narrowed down your issue?
