I need help with my new Samsung TV. When trying to watch Netflix, I get the picture but no sound except the sound from the cable network that I had on before connecting to Netflix. I have a BlueRay Phillips surround sound connected to the TV. With my old LG tv, I had to turn off the surround sound and turn up the volume on the cable remote but this does not work. I have 3 remotes in front of me at this point (cable remote, BlueRay remote and Samsung TV remote)--none of which will give me sound on Netflix. There is an HMDI cord plus a red, blue and green plug in plugged into the back of the TV. thanks for any help you can give me!
