Got off the phone with dish rep about pixellation on Mtv2 and they said it might be a bad transponder in the lnb. They suggested I take them to the dealer to test them. I figured if I just swapped the 110 and 119 lnbs that would rule out if one of them was bad. I did it and still have the problem. All the connections are tight. It is only on the channels with transponder 21 which I only have a few. I have a signal strength of 112. Any ideas?
