Reception disturbances
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 satellite. The most common types of television

symptoms appear when the television is
connected to a Cable TV system, the
disturbance may be caused by the local cable

Symptom Possible cause Possible solution
IGNITION: Black spots or horizontal
streaks may appear, picture may
flutter or drift. Usually caused by
interference from automobile
ignition systems, neon lamps,
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 signal is 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 normal
when you adjust the CONTRAST or
BRIGHTNESS setting.
