I am hoping you can please help me. I have spent the last three days going through your website trying to figure out was is wrong with my cx7150 to no luck. Please let me explain. two years ago i replace my cx7150, or (RMA) . Another unit was sent out, at that time I couldn't figure how to set it up. so i never use it. Recently I thought i would try again to set it up, but not able to again. I am disable and i truly having the hardest time with this. I WOULD love to use this system one day. please help.
