ERROR 602 "Point Dish can not be run since a tuner can not be acquired for either Satellite Input 1 or Satellite Input 2." I just replaced a defective hard drive, did the proper procedure for restoring 921 image (L055, L277 method). Everything went fine until after the hard drive was successfully remarried. For some reason the receiver keeps rebooting when satellite inputs 1 & 2 are connected to my dish. When they are not, it just says "Acquiring signal.....", but then just goes to a blank screen. When I call up the Menu and try to do a switch check, it comes up with the error above. Anyone have any ideas as to how I can cure this?
