•IGNITION NOISE:
Black spots or horizontal streaks may appear, picture may flutter or drift.
Usually caused by interference from automobile ignition systems, neon
lamps, electrical drills and other electrical 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 some
other objects. Changing the direction or position of the antenna may
improve reception. Ghosting may also be caused by defects in the
antenna system such as unshielded leads or connecting several sets to
the same antenna without using multiple antenna couplers.
Ghosting occurring when the TV is connected to a cable TV system may
indicate a bad cable wire or loose connection. Confirm that the cable wire
is properly connected.
•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 a special antenna to improve the picture.
Snowing occurring when the TV is connected to a cable TV system may
indicate a bad cable wire or loose connection. Confirm that the cable wire
is properly connected.
•RADIO FREQUENCY INTERFERENCE:
The interference produces moving ripples or diagonal streaks, and in
some cases, causes loss of contrast in the picture.
