    I have an old installation with a slimline dish going to a SWM-8 and then an 8 port green label splitter with a power inverter. I have two HR24 and a DECA ethernet adapter connected to it. Used to have HR20s so needed the additional ports.

    During the last few months, I started to get transponders going to zero and back up to mid-90s after a few seconds. Sending a refresh signal and a reboot took care of it, except it would happen again after a month or so. AT&T online sees the receivers as offline, even though they are online.

    Tonight, both receivers went dark and got 775 messages. Rebooting did nothing and could not send a reset signal cause I could not log in (apparently servers went down is what I was told when trying to reset passwords even though that wasn't it). Power Cycled the power inserter (even though it was green) and was back up.

    D* wanted to do a truck roll for $20 but refused. I'm not on contract and very close to jump to YTV and Sling (for Spanish tier - I have an old Option package). Not doing any protection plan nor extending contract. Besides the dish which is old but still works, what should I replace?

    Power inserter? SWM-8? Splitter? (I do have a 4 port splitter that I could replace it with).

    I had a SWM-8 go bad, but that's only cuz the idiot who serviced my A/C decided to bury it in the insulation in the attic. I only went up to the attic cuz my TV went out... surprised that thing didn't start a fire, it was hot when I pulled it out of the insulation.

    I'd start with that, it's a cheap part and likely the culprit. I had similar symptoms.

    Call them back and let them come out.
    They will put you in a new LNB. This LNB will do away with the need for the SWM 8 box that you have.
    They will cure all your problems.

    Your issue Could also be Just "water Damage" of Exposed RG6 Connectors

    A service call -Will NOT Start any New Contract -- as long if you need a receiver replacement -and they replace it -Like for like --NO contract -- Hardware (lnB) Wire -Switch -or Splitters do NOT create a contract

    The power inserter is easy to test for voltage. It's either 21 or 29 volts.

    Sounds like the exact issue I had last summer. Turned out to be a bad LNB.

    But it does create $100 charge ;) unless you have PP. I specifically put my SWIM in the attic so I could service it myself. The Swim / PI / splitter generally come as a single bundle on eBay for a lot less then a $100.

    A SWM8 will run fine on a PI21. Directv doesn't spec that, but the SWM8 doesn't draw enough power to come close to maxing out a PI21 unless you had a long run of CCS wasting power also. Even a SWM16 would work, but then you are getting too close for comfort to the output wattage for that to be a good idea.
