Hi, read numerous posts regarding SW34 failing to see/recognize LNB's. I have a new Superdish 121 with SW34. Running check switch shows only the 110 LNB as connected. Never sees 121 or 119 LNB says... "error detected, check connections" Well we checked and replaced the cables, same answer. Moved 110 cable around non switch and it moved between ports 1 ,2 & 3 when re-running switch check.
Is it likely that I have a bad LNB for both 119 & 121 ? Do I need some sort of signal in order for the switch to recognize the 119 or 121 LNB's ? (I didn't think so)
Spent hours and hours messing with this, could really use some expert assistance. Thanks so much.

What I did before connecting to the switch was connected each lnb, 110, 119 & 121 directly to the receiver, when I made sure I had all sats and peaked them, I then connected the cables to the switch, this way you can determine if it is a switch or lnb problem, of course once you have eliminated it being a cable problem which I think you did

What Sandman said. Yes, you do need to have signal before using the switch.

Finally, you better be using a DP34 and not an SW34. It's really hard to connect cables to something that doesn't exist. ;)

A DP LNB will be recognized by a switch test if it is working and attached to the switch. It should list the LNB type and will say N.C.(for not connected). The LNBs from the 119 and 121 should be llisted as feeds, and they will be listed on the installed switch something like this:

DP34, DP Dual, DP Single, DP Single.

once you verify that you are seeing the LNBs, then you will have to check the pointing of your dish. It is entirely possible to get a signal from the 110 and not the 119 and 121 if the dish's settings have been altered.

The FSS and closest LNB on a SuperDish (which show up as "feed" on a properly alligned dish) need to be able to see a satellite in order to report to a DP34.

You need to have a signal on these two LNBs before the switch will see them.

Yes, it is a DP34 switch, sorry. Still trying to determine if a signal is required in order for the switch to recognize the LNB. The dual 110 LNB reports in fine, the 119 and 121 always show "no conn".

Well, 3 out of 4 experts posting in your thread agree, and if larry stops back, he'll probably see th error of his ways. ;) I don't know what else you want.

Always peak on 119...on the first port than 110 and finally 105 or 121...If the signal still not there ...Verify location anything obstructing? Sounds that way... :confused:

I ran a check switch on a SD install with the 121/119 last week. It came up as feed/feed no signal. I will check it out on my next opportunity. The DP design is supposed to allow for the receiver to detect the LNB regardless of whether it has a signal or not. If I am wrong, it wouldn't be the first time.


Yeah, unfortunately, I have been unable to get online that often lately. Hopefully that will correct itself soon.

I tweaked my 105 in by connecting a direct cable to the 119 LNB and getting a decent lock on that (with proper skew and elevation set for 105, of course) then moving the direct cable over to 105 and peaking that to the best I could. 70's appeared, and amazingly enough when I connected to the 110 LNB and 119 LNBF I had signals there too!

Which is something like the manual tells you to do. :D
