Sproadic Error Code 771 on HD-HR25-700 - All Channels

Since the move of my equipment to our new home 2 months ago, the problem occurs with only this 1 box (all other boxes are fine). It affects all channels but cycles in and out. It will go for days without happening and then it will happen a few times. Sometimes it will come back on all by itself without touching anything... outage lasts anywhere from 1 minute to 5+ minutes.  I've replaced the connector on the end of the cable and that reduced the problem from constant to the periodic outage above. Is a service call in my future?

What the model numbers of your other boxes?

What happens if you swap this "bad" H25 with a good box?  Does the problem follow the "bad" box, or stay in that room?

I swapped boxes and the problem stayed with the room. After some debugging, it turned out to be a bad cable somewhere between the splitter in the attic and the box. I ran a new 20' cable and walla! Thinking about it... that cable was the original from when "CableTV" was 1st installed in the home in 1987.  Never thought a cable could just go bad, but after speaking with several folks, they say it happens all the time with older cables.  Thanks for your help!
