Texasclaw, this may not be of any use, but going back over this page and page 3. I found out that you've replaced your lnbf. Well, I changed one out once (actually more than once), and had problems similar to what you appear to be having. Some channels would be OK and some channels would not come in. I was even getting signal strength on some of the channels, but they wouldn't come in. I figured the PID's must be off, so I played around with them, but I couldn't get the channels to come in. Very long story, put short, I had to delete the channels completely from the system and start from scratch. After doing this, the channels scanned in. My summation was that the different lnbf caused different readings in the receiver and the old readings were so close they caused an interference with the new readings and it gave me blank channels. I don't know if this is what is happening to you, but it could be? You can try this with one channel, write down what's currently in your receiver (so you will have it, if you need it), then delete everything to do with that one channel, that includes the channel as well as all information saved from scans from possibly 2-3 different menu's in the receiver. Try to delete everything to do with that channel, then do a new scan. If it doesn't show up, try a manual scan. Good Luck!
