I have found something strange in tuner setup. transponder 12012 V 29500 3/4 28.2e Will show no signal if you try to scan it. if you go to tuner config and set your tuner to 25.5 e you can then scan that transponder and other HD transponders and the HD channels will work but obviously the channels that are scanned on 28.2 then say tuner fail. This is using a fixed dish pointed at 28.2
