The problem started a week ago, all the sudden, the guide is showing all the channel as "To Be Announced". The receiver is the HR20-700 hooking up to a SWM16 with a DECA as per instruction from DBStalk. Everything was working fine until a week ago. I've went through the dish setup, reset everything, the guide is there after each of these steps but after an hour or if I turn it off and back on, all channel will said TBA. I've called DTV and they are sending a tech over because they think it is my signal but I have 5 other receivers all are working just fine. Any one has any idea what I can do to fix this? DTV tech won't be coming for another 4 days. TIA.
