Installed a Zinwell WB68 to add a 5t receiver. Noticed two things that have me puzzled. First, on my H20-100, the system test states "LNB Output Failure" but I seem to be receiving everything I'm subscribed to. Second relates to the Slimline dish. When I called to upgrade my system for the "new" HD I guess I expected to have 5 LNB's. When I access the receiver setup page the system asks which type of dish I have and defaults to the "3 LNB Oval" selection. I'm in the Dayton, OH (45458) DMA if that's any help. Is this normal and, if not, should I run setup again and select the 5 LNB option? Are my two concerns related? Note, I did not run setup again after installing the Zinwell as everything appeared to work correctly. Any advice is appreciated. (I've also posted this to the DirecTV Forums lookin gor an answer)
