Why is my TV skipping channels it has no picture just a snowy screen?

It is hooked up to Dish Network Satellite Cable DVR nothing has been disconnected from the DVR is my TV going to work or is it broke

Update:

It is a 2002 Sony Rear Projection TV & this Sunday I will be adjusting the Convergence Box inside the TV because of Vertical Green Lines the picture isn't distorted not seeing double of the same item on TV.

    You're on the TV tuner and not the AV input where the DVR is connected. For instance on my TV this would be INPUT 6.

    Your TV needs to bet set to the channel or input to see the signal from the Dish box. Then you leave it there; you change channels with the Dish box.
