Surround cuts out??? (by 2 users)

Are you useing a digital audio cable when its cutting on & off? How long between the on & off? I have the same problem when I use a digital audio cable or a coaxial audio cable from my DVD player. To use the surround (6 CH) feature you need to use the 6 channel RCA jacks and if what ever your hooking up dosent have the RCA outputs your out of luck. My DVD player does have the 6 channel outputs and they work but the digital cables won't work. What are you connecting to it? I think something is wrong with the digital circuit board in mine, I would like to replace it and see. Reading your manual will help understand the 6 channel RCA and fiber optic digital cables. I hope any of this helped.
