I scanned G10 with my Viewsat 2000 and got everything. When I went bac to watch today I had no signal or picture on the 11720 TP. I get all of the 11800 channels perfectly. I could not get the channels back by either a regular scan or blind scan. I swapped the receiver out for a Traxis 3500 and it found them all immediately. I have the latest frimware in the Viewsat and it did find them first try yesterday when I set it up. Any ideas would be appreciatted.
