Hello everyone. Thanks for the forum I've been a long time lurker but I finally got frustrated enough to join. So any help would be greatly appreciated. For starters I'm not an expert in any means but consider myself teachable and handy. With that I have DirecTV with a slimline 5 dish and a HR 23-700 reciever. I started losing channels I noticed a week or so ago, not all but certain ones like history, espn, and some others. It started that I would lose them at certain times of the day, mainly mid day. However eventually I lost them for good. Sometimes it will say searching for satelite on input 1 and sometimes it will say input 2. I checked my signal strengths and they seem fine from what I know. What I don't know is how the different satellites 99, 101, 110, etc work because I seem to get signal on 110 except for 4 12 20 28 transponders, reading I gues those are "spot" and I do get my local channels. However the other 99, 110 I don't think I am getting from them, and that is where my common sense ends. I think I might have a bad LNB but like I said I really don't understand how it all works so I don't know. Thanks for anyone who takes the time to read this and let me know what you think.
