Well, it seems that the LNB is not bad (I found no shorts and there was different readings from pos-center to neg-side and vice versa).
Sadly, I'm going to start removing everything (including the pole that I had to put in the backyard).
I would like to thank all of you for your patience and guidance, but it just wasn't meant to be. It was too much time invested with no results so my wife has demanded that I cut my loses.
Thanks you for all the help!
Why would you want to give up so easily? after all the investment, you have one last thing to check before throwing in the towel. have you verified that your receiver is working correctly? Receivers can appear to work, they can boot up, navigate the menu, etc., but if the LNB voltage tap on the power supply is smoked then you won't get any signal. This occurs when you've make and break LNB coax connections without turning the stb power off. I have repaired 2 stb's due to this because 2 of my friend's played around with their dishes and then called me to rescue them. If you have another stb or access to one, try it!
EDIT: Most power supplies can be repaired easily. Capacitors blow easily when you don't power off the stb.
