LNB Problem (Can see only Odd from 119)

[Mdknapp]

Hi all,

I have a problem with my setup and I have tried just about everythign to fix it. I can't think of anything else other than a bad lnb... but perhaps someone else can help me out.

I have a sw-64 switch hooked up to 119, 110, and 61.5. This setup worked perfectly until it simply stopped receiving signals from 119 evens about 3 weeks ago.

To try to trouble shoot I removed the sw-64 from the equation.And set it up with an sw-21 to both 110 and 119. This did not work as 110 e/o still came in and 119 o but not even. I tried each lead from 119 with 110 and each time it was the same problem... so I don't think it is the cabling to the lnb.

I also tried both my 501s (I have a 4900 as well) and both my 501s had the same problems in both setups from the sw-21.

Now, I have not made sure the lnb is clear of bird dung on the end of it (could that cause a problem) as it is hard to get to. Does anyone have *any* other ideas of what could be wrong other than a bad lnb?

To confirm the checkswitch shows simply an X for the satellite and an X for the transponder where the 119 even should be.

Any ideas or guidance are really appreciated!

Hi Matt,

Do you have two dual lnbs on the Dish 500?

You can set the point dish screen to 119 odd then even and measure the voltage on the cable at the lnb (with switches bypassed). If the voltage is switching and you still cannot get signal from 119 even but odd is ok then it does look like a bad lnb.

From your statement below it seems you have not connected a cable from the receiver directly into each port of the 119 lnb and tested.

Remember to do a check switch after changing a configuration.

You can also swap the LNBFs move 110 to the 119 port and move the 119 to the 110 port the problem should switch to 110 if the lnbf is bad.
