I got a new LNB for my Dish , I live in Nevada and can get a good signal . I put the new LNB on and only get some channels most HD 300 and up and almost none from 3 to 80's . I put on Old LNB and all is good . I was told I need a new V code by calling shaw. Since I live so far south should I even bother calling ? It looks like I wont be picking up the new HD channels anyways. Any info would be great. Thank you
