One TV in the house gets interference on the higher channels (50 and
up). This has been happening for over a week now. One minute it's
fine, the next there is nothing but "snow," and static noise. There
seems to be no cause of this, and it does not effect any of the other
TVs, 2 of which have premium cable and 3 that have basic, just like
the one with the problem. There was interference on a radio that
plugs into an outlet, but not with a radio that runs off batteries,
even though they are in the same place. The radio problem, however,
was bad about a week ago, but then the interference just stopped.
This TV problem goes on all day and night long. We have no new
appliances or anything like that. Any ideas?

Thanks.
