If the controller doesn't respond to the +/- gain control buttons, I would assume something is wrong with it. It should be warrentied. I'd return it to the parts counter for an exchange.
Actually, I would first un- and then re-install the controller to make sure that both harness plugs and each wire in both plugs are securely seated in the controller. This could be a minor wiring glitch caused by a bent pin or broken wire. You can also use a multimeter to check voltage and grounds of the leads as described in earlier posts of this thread. Then take it back if you can't make it work.
