    Hey guys, question for you. I have an HR44-200 with two mini clients. Also have two older DVRs that share playlists with the genie.

    Came home from being gone for a week to 771 error...but it was cloudy outside so I thought nothing of it. This morning, same thing, but with no clouds. On my genie, some channels come in clear, some give 771.

    I ran a signal test and posted the results below. My assumption is that something has broken, but I don't know what. Any idea what these results would indicate? Thanks!

    Notice that every other vertical lines of signals are zero.
    This could be a bad connection in the coax.
    It could be a bad LNB.
    It could be a bad SWM 16 box ( If your system has 1 of those ).

    Thanks. I have 2 SWM 4s.

    Everything worked perfectly until a week ago so I doubt its a bad coax connection, but maybe?

    DTV is sending a tech out tomorrow, looks like they'll be replacing something.

    Is there anything I can do to try and isolate the issue?

    The things you refer to are not what I was talking about.
    What you described is called a splitter.

    The SWM 16 box turns an old LNB using 4 coax cable to it into the SWM system that only uses 1 coax per receiver. They are probably 6 times the size of the splitter you have.

    Good, the tech will find the problem and fix it.
    Please update us with what he found. Some, like me, learn from reading what the solution was.

    With a tech scheduled for tomorrow I would not mess with it.

    Sorry about that, yes, I know exactly what you're talking about. Once he diagnoses and solves, I'll let you know. Thanks for your help!

    I'd say its your SWM. I saw similar symptoms when mine went out. Cheaper to buy one and replace it yourself then a tech call ;).

    But he probably has a SWM16, in which case it could be the SWM it could be the cables it could be the LNB. Since he doesn't even know what he has ("2 SWM 4s") he's probably better off having Directv fix it.

    If you have all info about your dish [LNBF], cables, possible SWiM switch and splitters, we could make more educated guess...
    Does the installer come ?

    Odd transponders use 13V, even use 18V, from receiver to select odd or even. If you have 4 wires to LNB, this suggests one is bad (cable, connector, something). If your LNB is SWM, then it is a defect in the LNB itself. All of your odd transponders are out, so the 13V choice isn't available for whatever reason. Much more detailed description of your system would allow better suggestions, but with installer due so soon, isn't worth the effort.

    UPDATE: tech came and found water in my SWM 16. He switched out my LNB for a new one (he said it was digital?) and basically bypassed my SWM 16 and plugged one cable from the satellite directly into a power adapter from there into my splitters.

    All is working well. Would love for you guys to help me understand what he actually did.

    Thanks!

    It's DSWM LNB, support 22 "channels" eg individual transponders, also it should have RB [reverse band] support (for future expansion … yeah, now the future is not bright for that :( - look at other thread's discussion like "T-16 launch")

    The older dswm lnbs only support 13 tuners. That could be what was installed.

    They aren't making those anymore. Directv has a policy now of installing only a SL3RB LNB for all new installs, so that's probably all he has on the truck anymore. No more SL5, no more second dish for internationals, the content of 95 & 119 are both mirrored on reverse band now to allow one LNB to work for all customers.

    I knew the 13 channel dswms were older, but didn't know only the RB lnbs are being used now. Thanks for the info.

    He posted a picture of the LNBF - it's DLNB Gen2.
