    I have lost certain channels on all of my receivers today.
    I am missing all the channel that correspond to the even transponders on Sat 101.
    When I go to the signal strength test, all of the even transponders are 0%
    The odd transponders are around 97%
    What is causing this?

    Most likely a multiswitch and/or dish failure.
    Do you have any splitters or anything installed on your sat line?

    It is possible that the tuner went bad.

    Did you introduce a new receiver?

    Have you tried a restart of the unit

    I have 3 receivers and they are all experiencing the same problem.
    Must be the muti switch of the LNB.
    thanks

    I would check all of the cable connections.

    Could also be one bad cable, the 18V sat. 101° between dish and switch.

    Cheers,

    Remove the power for 15 min and try again. Tried and true.

    Huh. I had the same problem which went away when I relocated the receiver. That would have been the only time power was disconnected. Maybe that's how it got fixed. You may have solved my mystery.

    Yes it could be the cable.
    I had a lot of rain yesterday and it could have got moisture into the cable.
    I have another dish mounted on a tripod.
    I am going to set it up and use it to troubleshoot..
    I was just looking for an explanation of why it was effecting all the odd transponders and not the even ones.
    And it is only 101.

    Well if you have a multi-switch, it could be just that cable with the problem.
    101 "odd" uses 13 Volts DC & 101 "even" uses 18 Volts DC to select the transponders.
    So From your first post... it looks like the dish isn't getting the 18 Volts.

    I swapped the cable with a piece of coax I had here, and it's fixed.
    There is no visible damage on that piece of bad coax at all.
    It just proves coax is a strange animal.
    At least I don't have to wait until Tuesday night when the DTV repair guy was coming to watch TV again.
    I will make him crawl under the house to run the new line though.

    It's funny that you and I had identical problems at the same time with two completely different causes. Strange animal indeed.
