It appears I have lost my 99 odd signal. The test channel (563) just gives me a 771 searching for signal. I can not receive many of my HD channels, including HDNM and my HD locals. I'm getting the same thing on both of my HR20-700 receivers. I have a Slimline-5 dish. All of the other test channels, including the 99 Even test channel are fine. Does it make sense that I would lose my HD locals & HDNM if I lost 99 odd? Also, does this mean the dish or LNB is bad? Or could this be a pointing problem? Any advice is welcome!
