What channel does your samsung tv need to be on to watch your dish network?

The channel your TV would need to be on to watch the DISH Network programming would be dependent upon how you have the receiver connected to the TV, for ex are you using an HDMI cable, CO axle cables, or an RCA cable? If you're using an HDMI cable then generally you would need to have your TV on the HDMI 1 or HDMI 2 input, if you're using CO axle then it would most likely be channel 3 or 4, and if you're using RCA then it is generally input video 1 or 2 or composite.
