    Notice that you have no "odds" on 103 tuner 1, just the "even" transponders. It's highly likely that you don't have any odds on the 119 satellite on tuner 1 as well, if this is a cabling/connector problem on the tuner 1 line, since these signals also require 13v + 22khz tone signal voltage. You may not have any odds on 101 tuner 1 either. (13v, no tone)

    The first step is to swap the antenna lines to see if the problem moves from tuner 1 to tuner 2. Just the antenna lines, not the BBC's attached to the back of the receiver. If the problem doesn't move, it's not in the cabling/connectors. Then switch the BBC's to see if the bad tuner swaps places, and you can leave the antenna lines in place.

    Please look at your 119 odds on tuner 1, and then report the results of the swapping lines and BBC's.

    Hmmm,

    Both of my signal meters have female connectors and so does every LNB if have ever seen. This cable has male on one end and female on the other. Installed ten or so older IRDs and they never had a patch cord just to test the signal with. Its almost not long enough for that...would only be about 6 inches comming out of the dish. Not sure... Anyone else get this cable with HR20 or 21...if it is a test cord did anyone get it with H20 or 21? I would love to know. I would call DTV but I don't but they know less about it than we do.

    IF YOU ARE HAVING 771 ON SOME HD CHANNELS WITH AN HR-20 RECEIVER I WOULD PUT THIS CABLE IN! Worked for me.

    An update: replacing the faulty cable was only a partial solution for me. The signal is still lower, just not low enough to lose signal completely. Instead, if the tuner is left tuned to one of the 'problematic' channels for a few hours, the sound will eventually drop, and never come back (until you change channels).

    I wouldn't be surprised if this problem existed in all HR20 installations, just that many will either have short cable runs (not enough signal loss to see a problem) or don't view the problematic channels, or just don't know enough to recognize a defect in DTV's setup when they see it.

    It's not in the receiver box; it's in the Slimline box. It's used at the dish so that the LNB doesn't have to be removed in order to insert a signal meter for re-alignment. It has a female on one end so that when connected to the antenna line no permanent barrel adapter is required.

    This is not a typical characteristic of the HR20-100 Sat 110 Tuner 2 Bug. Did you ever try the 3' patch cord?

    This means that you should try replacing your BBC's.....

    What's the difference here? Are you saying you reversed them out at the grounding block? This sounds like a separate issue with that cable only.

    Your facts are not entirely characteristic of the problem most are reporting lately with the HR20-100's on the 110 satellite, tuner 2 only. You may have that problem, but that's not all you have. I think you should get on the phone and get DirecTV to send you some replacement BBC's, based on what you have reported here so far. It's clear that you also had some problem with one of your antenna lines, which you corrected. From what you've posted, you still have not tried the 3' patch cord between the BBC and the receiver on tuner 2, and your BBC's are suspect. It appears you possibly have three different problems, and you've fixed one of them.

    That question has been asked and answered. Not all HR20-100's are effected. Although you may well be right that quite a few more may be effected than have been detected by users. Most people never check their tuner 2 signal levels on 110, and if they had signals in the 60's and 70's, they probably wouldn't notice the problem. It's only when they get in the 40's and 50's that the 771's start showing up on the 110 channels, 70, 71, and 73-78.

    I am also a new customer having this same problem. I'm not getting two HD channels, HDNet and ESPN2HD. When the Installer first came about 3 weeks ago, everything worked fine, after a heavy rain storm I lost just these two channels. The sent a tech out last week and he said the problem was due to a tree in the way and left. I called D* back and said this was unacceptable as these channels worked before and now they no longer work, they are sending someone back out today to see about moving where the initial installer mounted the dish. However, after reading this topic I'm wondering if where the dish is located is affecting the problem. I have two receivers, the main receiver, the one with the problem is a HR21-200 the second receiver is just a R15-500 that doesn't get HD channels. When I originally called into D* for the first call regarding the problem they had me go through a signal check and the person I spoke with said all of my signal levels were fine. I'm thinking about changing the cables going into the back of the receiver along with the BBC connectors based on what I've read in this topic but any other suggestions would be appreciated. Thanks in advance.

    I get zeros across the board for every transponder on every satellite on tuner 2. It appears this tuner may have gone kaput in my HR-20 100.

    It is true that those two channels come from the 119 satellite, which is ~20 degrees to the right and ~25 degrees above the center-line of the dish, which is aimed at the 101 satellite. (The ~25 degrees comes from the fact that the LNB is offset from the center-line of the dish.) It doesn't explain why you were able to receive it previously, unless that's a mighty fast-growing tree.:)

    Take a look at all your satellite signal strengths. If your 103(c)'s (national HD's) are mostly all in the 90's where they should be, but your 119's are low across the board, there's probably a line-of-sight issue. It is possible that if your 119's are zero across the board, the 119 section of your LNB died.

    Menu Button > Parental, Fav's and Setup > System Setup > Satellite > View Signal Strength. Use the arrows on the remote to change to 103(c) and 119. Be sure and check both tuners.

    It sure does.....have you ever done a Menu > ---- > Reset > Restart Recorder, powered down, and pulled the plug on that thing for a couple of hours before it has a chance to re-start?

    Probably not any that you are supposed to receive, unless you have a waiver for east coast DNS stations (ABC NY, CBS NY, etc.)

    Your 103(c)'s look great, but the 119's are terrible. How 'bout that tree? Can you visually confirm it's the probable culprit?

    Switched tuner 1 and 2 not switching the BBC's.

    103(s) Tuner 2 which is now connected to tuner 1
    0 0 0 0 0 0 NA NA
    NA NA NA NA NA NA 94 92
    96 46 0 94 54 0 96 0

    0 0 0 0 0 0 NA NA
    NA NA NA NA NA NA 0 0
    0 0 0 94 0 0 0 0
    NA NA NA NA NA NA NA NA

    103(c) Tuner 1 which is connected to 2
    0 94 0 92 0 92 0 94
    0 93 0 95 0 95 NA NA

    All NA

    I then switched the BBC's and placed the correct antenna line. Tuner 1 is still showing zeros for odds. What additional information do you need or troubleshooting steps I can perform.

    I take it that "Tuner 1" (big "T") means the antenna line that was connected to the Sat In 1 input ("tuner 1"). That is that you're saying you swapped the antenna lines, but not the BBC's in Step 1.

    Then I think you're saying that in Step 2 you put the original antenna line back on Sat In 1 (tuner 1), but you swapped the BBC's, and now the problem has switched back to tuner 1 on the menu pages.

    If this is all correct, the BBC's are OK, and there's a problem in the antenna line you had originally connected to the Sat In 1 (tuner 1) input. You'll need to check all the connectors in that line by removing them and inspecting for corrosion or perhaps a tiny piece of the braid shorting across to the center conductor (looking into the end of the connector.) Be especially aware of connectors that were loose and both sides of wall plate pass-through adapters.

    It's very common in new installations to find loose connectors, including those connected to the LNB inside the LNB support arm, but especially at the grounding block where the lines enter the house. Any slight corrosion build up in a loose connector can interrupt a 13v switching current, but an 18v one will make it across the corrosion. Re-tighten all connectors until just snug with a 7/16" wrench.

    Also make sure there's no diplexers for OTA antennas or cable TV-type splitters installed somewhere in this cable line from some previous installation.

    This cable was not in the Slimline box. I am absolutely possitive because I put the slimline up several days before I received the IRD. The night that I opened the box for the IRD I couldn't figure out what it was for. It is kinda short...like 20" (I haven't measured it) I thought it might have something to do with the RF Remote port that I am not using so I put it back in the box. Won't work for what you are suggesting...and just how many times am I going to realign this dish??? I hope never like all my other installs. By the way the it is still working with this cable in...take it out and 771. DirecTV owes everyone and explaination on this one.

    Last Saturday I finally had a tech come to start the process of figuring out the problem. After going through the standard steps of narrowing down the problem, he agreed it was strictly a Tuner 2 issue with the HR20-100. He replaced all the connections inside and outside of the house, replaced the BBC converters (now my 4th pair) and replaced the box with a new HR20-100 as a test of last resort.

    It's finally been a few days without any problems, but then again, I haven't fully recovered my list of programs to record which was HD heavy. Who knows if the issue will reappear, but for now, it's working smoothly.

    I have the "771...searching for signal" issue as well, but mine is with an HR20-700. It alternates between Tuner 1 or Tuner 2 sort of randomly. Here is more info that makes me think software is at the heart of the issue.

    I have a HR20-100 and a HR20-700 on the same Zinwell switch (the standard 5x8 model that comes with HD installs) and Slimline dish. Signals on 101 are all 95 and higher with 13 transponders at 100 on both receivers. Signals from 103c are in the low to mid 90s on all active transponders. My dish has been tweaked.

    Sometimes I turn on the HR20-700 and the current channel is blank and "searching for signal" on either tuner 1 or 2. It varies. Downstairs on my HR20-100 both tuners are fine. To me that rules out the dish. Since the affected tuner on the -700 varies, that eliminates cabling and the multi-switch in my mind since both tuners see the problem and are different cables and different switch ports. All cabling is RG6 Quad-Shield.

    Everytime this happens, all it takes is rebooting the HR20-700 from the menu and the problem is fixed (until it happens again some hours or days later). I have found two things that will trigger it. First, if I change channels on the -700 rapidly, I can frequently cause the 771 error. Once you get it, you can only clear it by rebooting. Another thing that will trigger it is actually losing signal on a tuner due to rain fade. I'm in the deep south and we have "frog strangling" thunderstorms down here...:lol: When you lose signal on a tuner in the HR20-700, it frequently never comes back until you reboot. My downstairs HR20-100 recovers fine during the same event on either tuner.

    This all makes me think software is the heart of the problem. Otherwise, why does a simple reboot fix it? I don't touch cables or BBCs, I just reboot and it's fixed- no matter which tuner was having the 771 issue.

    This started- to the best of my recollection- when code was added to support the SWM. At least around the time I started seeing guys with SWMs in the CE forum talking about seeing version info for the SWM on the setup screens, I started seeing this irritating 771 problem.

    Adding the cable helped for a few days...back to 771. Only on Tuner 2...never Tuner 1...and only on 110 Satelite.

    Why don't you try a 3' cable, which seems to work for quite a few folks, instead of that shorter one you're using?
