How do I stop my DISH TV network from turning itself off at night?

My TV comes up with this message that says the dish will be turned off due to inactivity... yes I haven't turned the channel because I'm watching this channel. Also I like to leave my TV on at night for the noise, the dish turns itself off EVERY night causing my computer to have the "snow" affect and make that horrible loud noise that woke me up. How do I make it so the dish stops turning itself off?
