This is in all likelihood a cable problem and has fooled me many times. Double check the connections of the wiring harness between each of the boards to make absolutely certain that they are tight. Let me guess, the bass works and it's the mid and treble that don't correct? Double check the little cables that have what looks like an oversized phone jack connectors. THese are the data cables and must be positively connected. They must be pushed in until you hear the locking little "click". Nina at PDS technical support tells me she receives calls from techs on this more than any other problem. As mentioned, I've overlooked this one myself. If this is not it then it is possible that you have a bad board, but in all the systems I have installed or repaired I have never seen one that didn't work at all. Typically when one goes bad a section of 6 notes will stop working. This is because every six notes shares a tiny little board mounted fuse. These are the little green resister looking thingees placed after each of the 6 sets of rectifiers going out to the connector pins.
