Most types of television interference can be remedied by adjusting the height and position of
the VHF/UHF antenna. Outdoor antennas are recommended for best results if not using cable
or a satellite. The most common types of television interference are shown below. If one of
these symptoms appear when the TV is connected to a Cable TV system, the disturbance may
be caused by the local cable company broadcast.
IGNITION:
Black spots or horizontal streaks may appear, picture may flutter
or drift. Usually caused by interference from automobile ignition
systems, neonlamps, electric drills and other electric appliances.
GHOSTS:
Ghosts are caused by the television signal following two paths.
One is the direct path and the other is reflected from tall buildings,
hills or other objects. Changing the direction or position of the
antenna may improve the reception.
SNOW:
If your receiver is located in the fringe area of a television station
where the signalis weak, your picture may be marred by the
appearance of small dots. When the signal is extremely weak,
it may be necessary to install an external antenna to improve
the picture.
RADIO FREQUENCY INTERFERENCE:
This interference produces moving ripples or diagonal streaks,
and in some cases, causes loss of contrast in the picture.
PICTURE SIZE VARIATION:
A slight picture size variation is quite normal when you adjust
the CONTRAST or BRIGHTNESS setting.
