I finished setting this system up today and I am having a few problems. I connected my cable box using component cables into the cable/sat in plugs. I am getting sound, but no picture. Also, I am having to turn the receiver up to about 70 to 75 to get a good, loud sound. Is this normal? THere was a little bit of back ground noise during the Audessey setup so I will run it again without my little one in the house. I have also read about the active bass setting. How do you turn this on? The sound coming out of the sub is not that loud, once again, it may be that I have to redo the Auddessey setup.
