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.

Have you tried a different outlet? Maybe it has a bad ground.

Try plugging this TV into a different wall outlet, preferably on a different
circuit. If the problem goes away, replace the outlet. If the problem remains,
swap this TV with one of the ones that isn't having a problem. If the problem
follows the TV, then replace the TV; if not, then repair or replace the cable
to the problem location.

I have a similar problem with one AM radio station. In the office,
one radio works all the time pretty well on this station 50 miles
away. The same day or night.

In the bedroom, another radio works fine at night, but during the
daytiem it either gets a lot of interference, or on other days it is
totally impossible to hear.

Also with apparently 5 other TVs and probably lots of splits along the
way, you may have a marginal signal left on the cable.

We had the same problem in a large house we were remodeling.

The cable company (Time Warner) provided us with a booster for the
whole system.

It worked like a charm.

If I remember right t cost between 80 and 100 dollars.

Bargain really.

They also advised us not to buy splitters from the home centers (ie
Home Depot or Lowes) as the quality of those is not so good.

Hope this helps.

These are both using antennas, and only 50 feet from each other.

It's a real pain to move one radio, but I guess I could move the
office/bedroom one to the bedroom and see how it works there.

Unless the radio interference exactly coincides with the TV problem, I
think you have a TV tuner problem. Try running the signal into an old
VCR and use that as your tuner and see if the problem goes away.

Possible interference sources include aircraft and ground radar (near
airports), cellular phone towers and cell phones (the new GSM band
phones are particulary nasty), abandoned antenna amps (possibly in
neighbors' houses) that may have been disconnected from RF cables, but
are still powered up. Also power lines, (the intensity can vary with
the current load throughout the day.)

Then there are the old fashioned sources of interference, electric
motors, vacuum cleaners, paper shredders, can openers, etc.

The timing and freqency can be clues to what is causing the problem.
For example, periodic interference every few seconds or so can be a
radar unit. Often these come on at the same time of the day.

A ham radio operator with a spectrum analyzer can help you track this
stuff down if you are motivated enough.

AM Stations come in different varieties. Some of them switch power or
change radiation patterns at specific times defined as local sunrise
or sunset. Weak stations usually come in only at night when the
ionosphere is hundreds of miles higher.

I think the OP should wiggle the cable connector at the back of the TV.
It's common for the solder connections that hold that to be cracked and
intermittent. An easy fix if that's it. MIght even just be a bad
connector on the cable itself.

.... A good suggestion. Also, make sure you are using high quality
cables such as the RG-58U Quad shield type cable. Cables with a
cheap shield will both radiate and absorb interference from external
sources. For example, a poorly shielded customer cable coax jumper
from wall outlet to the customer's tv may pick up interference from
broadcast stations. Since CH2-13 is the same frequency allotment for
both cable or broadcast tv, and since the cable signal may be delayed
due to satellite source or lots of amps in the line, the interference
is likely to be severe.

A discrete, sudden ON/OFF type of interferece is a good indication
that the source is man-made (i.e. public safety radio, radar, aircraft
communications, etc.)
