Tech came out today. Right off the bat he tried telling me that 103(b) wasn't lit up yet, and that everything was normal. After showing him that I was getting readings on the even transponders, and then showing him this forum, he finally started to believe me.
We tracked the problem down to a connector on the LNB, it was bad. After that, the odd and even transponders lit up.
As he left, he said, "It's sad when the customer knows more about what's going on with Directv than us techs do." He wrote down this website though, and said he'd start coming here daily to find out what's going on.
I actually felt stupid for not checking the F-connectors on the LNB (I did check all the others).
