I hate this kind of detective work; it can be so frustrating. But then again very satisfying when resolved.

Retrace setting on my HD STB (3 choices) affects audio and pic. to varying degrees depending on WHICH channel you surf if set incorrectly. Time for a little “Process of elimination” until someone sees your symptoms and has an epiphany.

What was changed in your system just prior to this occurrence? Did you only add in a new 1050, or as many do when adding one thing, leads to changing another while they are at it.
Anything else changed recently? A strip surge protector, new interconnects the STB or dish were upgraded ?

You mention (when surfing) Are you hearing this only for seconds at a time as signal locks in, as you surf, or does the channel exhibit the behavior constantly when selected?
What is your signal strength on the dish locked in at?
A method, (very tedious) but often what it takes. Disconnect every part of the system, if you have DVD/VHS etc. Disconnect EVERYTHING, leaving only your connections between the display, basic STB, and 1050 active. Use the most basic setup, Video direct from SAT to Display, audio into 1050. Don’t go through any video switching in your receiver. (Sorry …not familiar with the 1050) If you are using multiple paths take these connections down to only one choice, so that if you have S-Video and Component for video, only start with one connection. Is it gone? Then change to the other video connection, is it back? Etc.

Before you go to all this trouble, I would confirm (details of what has been changed/added will help), that it is not a faulty STB. And double-check manual settings for that unit. I’ll try to find what I can on yours if you will list, the full model designation.
(Is there an owners manual acessabile on-line for your unit..I can access?)
