Can the receiver maybe be bad? I have a traxis 3500 with an xtreme II lnb. I get horizontal fine but no vertical. I am going through an sg2100 motor. Can I check the voltages out of the receiver? When I choose vertical for lnb type when I am on a H channel the channel goes away so I am thinking that the receiver is switching voltage up to the lnb. short of swapping out the lnb I am not sure what else to try. I have a winegard dish. I have an old direcpc dish I found for free a while ago, I will see if that lnb will fit my setup. Can anyone recommend a decent LNB? Thanks.
