I also have a satillite dish hooked up to the T.V. (if that makes a difference). Someone told me to use an s-video connector since my t.v. does not accept the vga cable. I connected the s-video to my t.v. and my laptop and I still don't have a picture or sound on it. When I switch the input on my t.v., it shows that the s-video is connected, but still nothing! HELP!!!!!!
