I've upgraded my 5lnb dish to a SWM 5lnb but lost some channels in the process. Could there be something wrong with the LNB?

I have two HR20-700's hooked up, both with no B-Band converters (as it's a SWM based system). Is it just that it's not aligned properly?

Here are my satellite readings:

Are these ss readings consistent with both dvrs? If so, it's likely alignment or bad lnb, what else? Did you simply swap one lnb for another? If so, have you tried adjusting the dish? If you do try to adjust it, do so in very small increments.

I have tried readjusting the dish And can peak 101 a bit more but 99 still doesn't come in. Both dvrs and both tuners show similar numbers. I don't want to have to but another lnb but does that seem like the culprit? It was new from solid signal, isn't it rare for lnbs to be bad?

Looks like an alignment problem to me. Your 103ca and 103cb signals are low also, they should all be in the high 80s or 90s.
I re-peaked the dish, got 101 to all in the 90s, with a couple of high 80s

But, 103ca is still high 70s, low 80s
103cb are all mid 80s

With 101 being mostly in the 90's, I thought I'd at least get something from 99, which is what made me think it was a bad LNB. How else can I peak it better than the dithering method on 101? I just use the receiver to peak with, putting the signal strength meter on 101 on an odd transponder.

I then peaked the elevation, then peaked the azimuth. Is there some special trick for 99? When I did it before, I followed the exact same procedure, but the 99 came in fine.

Use the lowest strength transponder on 103ca to tune it using the meter on your receiver (in single transponder mode, not all transponder mode). Once you get that peaked, then check 99.

BTW, make sure all the nuts are loose on the mount where the az and el can move, or you will just be turning the screw, and not actually moving the dish. Im sure you know this, but I have seen it happen before.

Also, hit the (-) sign on the remote, and verify is reports it is SWM connected.

I did loosen the az and el screws first, I can see how people would miss that, but I did catch that.

It is in SWM mode for sure, that was the first thing I re-checked.

I'll try peaking it on 103ca. It's dark already now or I'd be back up there doing it tonight. I thought I would only need to peak on 101 (that's what I did on 3 other SWMline installs and it worked fine, guess this one is just difficult).
