    I have a 3 LNB Terk S23 dish that I put up a few years ago. I have it connected to 3 DirecTV receivers, 1 high definition and 2 standard. Recently I have noticed poor reception, pixelization, dropouts, and no reception on some channels on my HD receiver. Mostly it has been SciFi, Discovery, The Science Channel and I can't get FX at all at the moment. I assumed if I was having a problem on the HD receiver that I was having the same problem on all receivers. Well, I spent most of the afternoon on a ladder yesterday re-aiming my dish. When I was done I still had the same problem on my HD receiver. So, I went upstairs to tell my wife the bad news about some channels not working and noticed she was watching FX! What is going on with my system?

    That dish has 4 outputs right? It sounds like you should have ane xtra output from the dish. Move the connection that feeds your HD receiver to the unused output on your 3-LNB. Also I would check the connectors on that run. Sometimes corrosion might occur on the inside of the F connector or the center conductor. If you have the tools, replace the F connectors.

    Do you have consistant signal strenghts accross all the satellites (A,B,and C) and all receivers?

    Yes, it has 4 outputs. I'll try the extra one and check for corrosion. I don't think I can check for Sat C on the standard definition receivers can I? I'll check just in case.

    Thank you very much for the suggestions. :)

    SAT C is at 110 degree. I have several SD receivers and have signal for SAT C. I installed my current 3-LNB in 2/05 w/ no leaves on trees, come spring I lost 1/2 of my HD channels. I had to move the dish 10 to the left because of the leaves.
    I'm not sure, but there are folks on this forum and AVSforum.com that may be able to tell you (or point you in the right direction) which SAT's and transponders broadcast which channels. I don't know if that will help you or not.

    Let us know what happens.

    As I think think about I don't think that last bit of info. is going to help in this situation.

    One thing you could do of course is switch out receivers. You won't have HD capabilities but it tell you if your HD receiver is going bad.

    One of my standard receivers is able to get a strong signal from Sat C so maybe I do have a bad connection on my HD receiver. Can't check right now because it's raining.

    A year ago I had a similar problem on my HD receiver (all OK on my SD receivers). Finally I called Terk and they sent me a new set of LNBs (a swap basis) and that fixed it.

    Did you try switching the coax cables at the dish? If there's a bad cable or connector the problem will move from one receiver to the other.

    I finally was able to get back up on the ladder yesterday and tried switching the cables. No help. Either my Sat C LNB is bad or my HD receiver is bad. DirecTV coming out this Friday to install HD DVR and new dish. I will post when I find out if that solves the problem with the old HD receiver.

    I had a similar problem with my HR10-250. Sat B would say Rt side not detected and i had a loss of channels. After hours of messing around and phone calls to D* I decied to buy a new LNB. Well turns out it was just a very minor adjustment on the dish that was needed. I did find out that all (or most) of the transponders should come in at a minimum of 50 or better. The minute I wanted 80+ I'd lose reception on some channels. Anyway, I have a new LNB if you need it!

    Well I had my HR-10 250 installed today and it working flawlessly. I did find out though that my Hughes HD receiver was the culpret and not the dish or splitter. Now I have to convince D* that I need to have them replace my broken HD receiver at no charge and everything will be good.
