    OK it is a SL3-SWM LNB, (however the 3rd of 4 port statement is a bit confusing). Dave29 does know his SWM equipment, so it is interesting to know some may have all 4 "ports". Seems like a confusing design decision to me.

    On to the problem. SWM installs are usually very straightforward. Thus i now vote for bad LNB. If no setup gets you working a new LNB is in order.

    Our posts were crossing and now I see yours.
    Some terminology is confusing me.
    If you have a SWM-LNB, not sure why you have a SWM designation all the way to the right of your description. You shouldn't have an additional SWM on a SWM-LNB.
    Try this.

    SWM-LNB<----Power inserter with power to the SWM-LNB<-------->Splitter to TV's

    Be sure the power is going to the SWM-LNB. The Power output of the P.I. maybe labelled SWM. If that works, add the ground pass through between the the LNB and P.Inserter. and you are done.

    And after changing any setup, you must reboot the IRD every time, each one of them.

    Yeah, the other 3 ports partially protrude out and are casted over, the 3rd port over is the actual threaded port that is used. It is not confusing if you see it, I just may have not described it that well.:)

    Yep. I've tried two different splitters, both the same model.

    Anyways, I moved the PI to the splitter location like:
    Satellite-->Ground-->SWM Splitter-->PI-->Primary Receiver
    ..............................................-->Secondary Receivers

    The primary Receiver is recieving all programming again, working great, great signal strength. The other 2 locations are still only getting transponders 1,3,27,29,31 on satellite 101, and everything else is of course, 0

    edit: And yes I have been rebooting the IRD's and PI each time. If I see "Hello your receiver is starting up" one more time I'm gonna shoot myself.

    Another thought is to bypass the ground, Check all cables & connectors.
    Start as simple as possible.
    LNB to PI , PI to receiver. Add splitter and use same power plug for two receivers (home wiring ground abnormality can cause funny activity on receivers) and add variables.

    Good luck
    It's not supposed to be this hard

    I have several so thats why I was confused. Mine, SL5-SWM and SL3-SWM , only have one threaded port (F connector).

    Did you try unplugging the receivers that aren't working, then plug them back in one at a time? Also, do they show they are connected to a swm dish in the satellite setup?

    As others have suggested, unplug all (non working) receivers, then plug them back in one at a time and bring them up. Don't move to the next until the one you are working on is working.

    Make sure each receiver is properly set for the SWM type of dish in satellite setup.

    If you can't get them going that way, move each receiver, one at a time, to the location that is working and try them there. And/or move the working receiver to a non-working location and test it there. That will help you identify if you have a wiring problem.

    Ok, so I swapped out the LNB to an SL5 I had laying around. Still having the same problem, but a little different. I am getting signals on more transponders, both even and odd numbered. I'm attaching a picture.

    Does anyone have any ideas. I have swapped out every single component by now...

    As you can see I'm getting a lot of transponders signal at 100 but it is still not working...

    Did you check the Sat setup screen to see if you have the right dish and multiswitch highlighted?

    I didn't see the suggestion for removing the SWS8 splitter and connecting the receiver directly to the SWMLine dish as a test?

    All of his receivers will work, hooked up 1 at a time, to the Power Inserter.

    Okay, then could the splitter be bad?

    if that is a fact , then its a bad splitter. how are your wires run in that house ? are they all fed directly from where you have that splitter at ? alot of times behind a wallplate or something there is an old cable splitter or something that will do exactly what you are getting. I unplug everything. Then I plug in the power inserter. Then I run thru the house and plug in all my receivers to power. then i go thru 1 by 1 and set them up. any other way things get screwy for me !! If you do it exactly like that, and individually you have had each one working without the splitter, then my vote would be a bad splitter. Ive seen that happen more than once on a swm job. Ive never seen a SWM LNB that works on just 1 but not the other 2. Its definitely possible though but if you swapped it and its doing same thing then i doubt it.

    I would keep it as simple as possible.

    I have attached a picture of the splitter you are using, and properly labeled the ports.

    Place the Power Inserter, at one of the IRD locations. 1 short cable from the IRD to the "Signal to IRD" port of the PI. Home run cable from "Power to SWM" port on the PI to the RED "OUT" port on the splitter. Connect your other 2 home run cables to any of the other white "OUT" ports. Connect the cable from your ground/dish to the RED "In From SWM" port located in the middle of the splitter and noted in the attached picture.

    Plug in PI, Plug in IRD at PI location, Plug in 2nd IRD, Plug in 3rd IRD, Watch TV.

    If symptoms persist, replace Power Inserter

    I've seen cabling for cable tv where multiple rooms are "daisy chained" instead of "home runned". Check those wall plates and see if there are splitters inside the low voltage boxes. I've seen this mostly with low voltage boxes being back to back.

    I home rolled a Slimline 5 regular system to a SL5-SWM on June 13th and had no problem.

    Just a couple of thoughts in order of what I'd do first:

    You can troubleshoot by running a new RG6 line from the splitter to one of the remote receivers (bring the receiver to the splitter if this is physically possible). If it works, then you can check each of the other ports one at a time to verify the splitter is working on all ports. Also, if the receiver works, this is 100 percent an indication that the problem is with your internal wiring in the house and now you know where to start looking. If it fails, then you have a dish LNB/splitter/outside wiring issue.

    When looking at transponder strength, forward past 103c. You will find SWM listed as if it was a satellite (at least it is there on my HR20 when set to SL5-SWM). Capture a picture of the readings on the primary and one of the remote receivers at a time. What this does is show the SWM channels and what kind of signal strength they get. The channels in use by other receivers can show up as a 0. So if you have bad readings on certain channels, it may give some insight what is wrong.

    Also, how far is the dish from power inverter? DirecTV recommends 15 feet minimum for 'rain fade' margin.

    Finally, be careful of getting the power output side of the power inverter connected such that it feeds the other receivers. I have heard this kills receivers.

    So have you swapped the lines on the splitter to see if the IRD that is working prior to the swap around of cables stops working and a non working receiver starts to work?

    I hate to ask but what are all the model numbers of your receivers?

    They are all H21's so I am familiar with the Satellite 103 fail. That usually fixes itself once I force a software update and reset.

    Anyways I went back to the original splitter since that didn't seem to be the issue after I swapped out the LNB. Once I swapped out the LNB I was able to get one of the secondary recievers working, which leads me to believe that the LNB was an issue, maybe I wired it wrong and blew it, maybe it was defective LNB.

    One of the other recievers still won't work. I;m getting great signal on 119, 110, nothing on 99/103 and random transponders on 101. (check my earlier post- I attached a pic). This reciever successfully works in the other two locations, so I think my problem was a combination of the LNB and now wiring issues to one of those locations. Although it is weird that about half the satellites work and half don't...

    As far as the wiring goes it is brand new RG6 all around. This is a 30 yr old office building that did not have any pre-existing wiring at all. The satellite is about 20-30 ft away from ground, splitter & PI. The PI is wired after the splitter in the room where the splitter is.

    I'm trying to figure out why that one room won't work. I used the same spool of wire for the other two rooms (in fact one of those rooms has 3 barrel connectors between the splitter and the receiver, but is only 30-40 ft away). The room with the primary receiver is located furthest away from the splitter (~100 ft).

    The room that refuses to work is just one cable beginning at the splitter and ending at a wall plate barrel connector. I've tried removing the barrel connector and wiring directly to receiver but it still doesn't work.

    I guess that one cable HAS to be defective, but for the life of me I cannot figure out how?

    Oh and I forgot who asked, but I have tried different ports on the splitter.
