Check the RCA cables in the back, make sure they are plugged in correctly, if not that can cause a snow picture on TV2. TV2 Should be on Air mode and set to CH 60.
Choose the channel guide button on your remote, check and see if your programming is coming in, if not call Dish to send a programming hit to your receiver.
If it's a silver colored VIP211, it's one of the older models and should be replaced soon. (They go defective very often.) Contact Dish and call them to have it replaced, they can either ship you out a replacement receiver or have a tech come out to replace it. If you activate Dish protect silver on your account it can save you from the $95 tech visit fee. Hope this helps! :)
You can Google the exact model number of your TV. One of the pages that comes up will be from the manufacturer and will contain the manual under SUPPORT or DOWNLOADS.
Did you connect to the output of a box? If so then it will usually come through your him I and doesn't require a scan. If cable set your menu setting to cable and not antenna.
