DJM-900 No Master Volume - Indicator Lights never turn on

I just bought the DJM-900 mixer along with a couple CDJ-2000 decks a couple weeks ago and until yesterday was just using headphones to listen to my mixes.  However I decided I wanted to hear it on speakers to get more of a live feel and so I used the Master2 output using RCA cables of course to connect to a Pioneer receiver (normally used for my home theater).  The problem is I get zero master volume and the indicator lights for the master volume have literally never illuminated.  I did read the Troubleshooting section of the manual and read to change the MASTER ATT to -6db which I've done.  I've tried everything else I know of to make it work and still nothing.

Somebody please help me see those beautiful lights and hear some beautiful music!  Thanks!
