OK, here's my other question. Thinking the Dish 500 LNB is defective, I took the entire thing down and put the 300 dish back up with the LNB that goes with THAT one. Now, when I turn on the receiver to try and get the Point Signal screen, I get nothing but "snow". I just changed the batteries in my remote 2 weeks ago, but when I press the system info button, nothing happens. I have also tried unplugging the 301 receiver for awhile, reinserting the smart card, still nothing. I need help before I call Comcast to come out.
