    I've been struggling with this problem for over a month. I have 2 rca directv 18" dishs, each with dual lnb's. I have one pointed at 110 and one at 119. I connected 5' of rg6 cable from each to a sw21 switch. I connected 30' of rg6 cable to the sw21 and to my 7100 receiver. I get it to see a sw21 switch but it says multi dish problem detected. I get 119 odd and 110 even and 110 odd. I don't get 119 even. If I switch the 119 and 110 dish inputs on the sw21 I get 119 odd and 110 odd, no evens. Any ideas what could be wrong?

    Have you tried running the lines directly to the receiver to verify that you are getting the corrrect signal. If you are, then I would have to say that you may have a bad switch. D* LNBs are the same as Legacy E*s so it should work. Was the SW21 new?

    I tried running direct to the receiver and get good signal on both 119 and 110. But I don't get it on all transponders. Just most of them, dosen't seem to make a difference if there odd and even I don't get some of both.

    I bought another sw21 switch and I get the same problem. One switch is the microroyal sw21, it dosent say sw21x on it. The other switch is the one with 2 inputs on one side and the output on the opposite side.

    Sounds like bad cable connections or that you have a splitter between or something between the sw21 that does not pass the switching signal from the receiver to the switch.

    Also the switch is coming up as sw21 3 sat. Should it be only 2 sat? 110 and 119?

    I get 119 odd and 110 even and 110 odd. I don't get 119 even.
    If I switch the 119 and 110 dish inputs on the sw21 I get 119 odd and 110 odd, no evens.
    The same exact thing happens when I tried a completly different sw21 switch.

    How are you hooking these up ?

    As suggested above, I'd do a direct connection between each dish to your receiver, doing the check switch test.

    Do this on both outputs of the 119 dish and the same on the 110 dish.
    It is possible that your LNBs have gone bad also.

    If the tests above are OK, then hook in the SW21 (one output from each LNB to the inputs of the SW21, output of SW21 to your receiver), then do the Check Switch test again. It should show connections to all (119 Even and odd, 110 even and odd). Then do the other one.

    You may also want to check your cables / connectors for corrosion, especially to the 119 dish LNB.

    Hook each dish direct to the receiver and do check switch test? What should it say? no switch detected? How do I know if an LNB is bad?

    A number one do you have one or 2 dish rcvrs?7100's are very finicky, for some reason while hooking up sw-21's you have to hook the left side of the lnb on 119 & 110 into the same switch.No problems with sw42 switches if you can find them.

    Unfortunately I only have one receiver to test with.

    One dish dosen't get 119 even when I do switch test no matter what. I swapped cables, switches, LNB's, everything except for the actual dish. It does get good sat signal though. Maybe I need to change the dish?

    Have you tried the direct connection yet? On both LNB feeds (one at a time obviously).
    If so, do you get even and odd on both?

    Ya I tried it and I got 110 odds and evens and 119 odds. I could never get 119 evens. I swapped cables, switches, and LNB's. Everything besides the dish. I could not get 119 evens.

    I swapped the dishs and realigned it. I still only get 119 odds. I can't get 119 evens. Any idea why?

    In dish signal meter I get signal locked on everything except for transponders 1, 3, 9. I get no good signal on 1 and 3 and 50 strength on 9.

    Not all transponders are operational on all satellites. 119-1 -3 -9 are all spotbeams that you may not have where you are.

    Use TP #11 & 12 for both 110 & 119 to determine "goodness". For details you can check here.

    BINGO - just saw your post #3 - sounds like your LNBs are OK - the missing transponders are probably correct - click the link above if you want to confirm it blow-by-blow, but it's probably not necessary.

    So, now let's go back to the SW-21. What 'dishsystems' said is a good idea - if for no other reason than consistency.
    1. Connect 119-left to SW-21 Sat #1, 110-left to Sat #2.
    2. Disconnect sat feed from receiver and pull power plug.
    3. Power it up and run Check Switch. This will reset it.
    4. Connect the sat feed and run Check Switch again.
    Life should be good and it's time for a beer and some TV.

    I followed your instructions, 1 through 4. Still the same problem, no 119 even. The only thing left is the receiver. Is it possible the receiver is injured?

    have you just tried checking your programming to see if your channel are there? The 7100's have had so many software issues it may just not be listing the test correctly.JUst cacel out after the switch test and do your usual 10 minute update and check your channels.If it is a bad rcvr usually all even transponders will be out.(common for all even transponders to be out from surge damage)

    If you haven't swapped the LNBs on the 2 dishes, try that.

    If the problem follows the LNB, then you need an new LNB. If it doesn't, then you need a new cable. It's that simple at this point.

    I swapped the LNB's and the cables. They're not the problem. I swapped everything except for the receiver.

    Then you're down to a bad receiver.
