My 3100 freezes every once in a while. Called Bell, they went thru the checks with me and said they reprogrammed my card but it still freezes. Their explanation is my receiver is the problem and I need to buy a new one....any other suggestions??
Possibly a cabling issue? If you watch the signal strength screen (menu 6-1-1), does the signal strength stay constant or does it suddently dip down to 10% and then back up again? I have seen cabling issues cause freezing. Are you able to borrow a friend's receiver for an hour or two (invite them by for coffee?) and confirm?
