Is it easy to blow LNB?

[covcomm]

I decided I wanted to move my Dish from a roof mount to a pole attached to the eve of the garage. Could not get it aimed, I moved it back to the roof mount and lined up the marks, I marked azm and elev with a sharpy. No go.

Ideas? Any dealers in houston where I can get another LNB?

TIA!!!

What makes you think it's the lnb? Sounds more like a L O S (line of sight) problem. You moved it, now you need to get it back where it was? I say this because it's very very rare for the lnb to go bad, although it can happen.
On another note, it could be a good idea to have a backup lnb...?

You really can't blow and LNB, even if you dropped the thing it will probably still work.

You probably don't have your alignment right or its an issue with the cable

Thx... I moved it back to the roof mount pole where it was. LOS is clear. I just wanted to make sure I was not fighting a bad LNB. The coax I was using to align it at the new position had a connection issue. It was intermittant. I was worried the make/break that happened two times wacked the LNB. I will go back out in the morning and make sure it is all lined back up.

I dropped a few LNB"s off my roof. The casing may crack but the LNB is still good

Was the receiver powered off while disconnecting the cables? Also, I would carefully inspect the cable ends if all was well before and alignment is back where it was.

Yes the receiver was off when disconnecting. I have seen many warnings about that on here so I was worried that perhaps the connection problem I had with my jumper caused some damage. I have a coolsat 5000 and the signal strength dropped way off a couple of times as I was attempting to aim. I am going back out there in a few minutes....

in my experience if you are using an disequ switch and dont turn off the ird and switching out lmbf's its possible to take out and lmbf or switch or both. i dropped an express view lmb once from a roof of my brother-inlaws cottage it survived .

I'm with AMC1 on this one, I have also toasted (only) 1 LNB because I accidentally left reciver ON with a 22khz/DiseqC switch in the mix. Luckily I had another one to test with so I could verify it was gone - got a replacement and that is what did it.
