    On Tuesday at 14:30 my receiver displayed error code 771a, with diagnostic 51. I know that means the swm power inserter problems. I tried unplugging it, verified all connections, etc. Well Wednesday night it started working again. Thursday morning it wasn't working again, and now Thursday night, its working again. I don't know what to do. I have a service call set up for Sunday.

    Any advice?

    Unless you have a spare power inserter there's nothing you can do until they show up on Sunday. It may also be the LNB that has gone bad. Best thing to do is just wait until Sunday and let the tech diagnose the issue.

    So the DTV tech came out to check my problems. Like I said, the system started working on Thursday by itself, well turns out there was a short in one of the barrel connectors in the cable from the ground block to the LNB. He was able to replicate the problem when he wiggled on the wires. He replace the barrel connectors and problem solved.

    Terrific news!

    Connectors, cables, and the like are often the "hidden culprits".

    Enjoy your newfound fixed HD!

    Great News!!!

    Bad or Loose connectors or bad cables are often the "hidden culprits".

    Enjoy.

    Glad to hear it's working but I'm just going to throw this out there.

    There shouldn't be any barrels in line from the lnb to the groundblock.

    That's a QC fail. Should be one continuous piece with a messenger ground wire attached.

    cheers

    don't the preconfigured swm lnb's use pigtails?

    I finally had time to test it myself. They shut down the computer Cabe Ethernet Media Center and tried to record two different programs. One that was already underway and that was about to begin for the future. Both programs successfully registered. Apparently Media Center does not require an active Internet connection to record shows. It's a bit strange that the error code using the same. I am very interested to know what the error code 771 / 2. Knowing that I would help prevent future Missed recordings.

    There were not any barrel connectors in line, it was the connector at the LNB that was bad. The LNB did not have a prefab pig tail. Once that connector was replaced and reconnected the short on the power inserter cleared and service was restored.

    And just to add/clarification. You can use a pigtail. There is nothing wrong with that. But if there is a barrel half way down from the dish, then it's a fail.

    Pig tails are a necessity on service calls. You can't always reach the LNB to peak a dish.

    The real issue is one solid piece of cable with a ground wire attached to it.


    (This is all just QA/QC procedure.) Personally one barrel in-line is most likely not going to make a difference.
