RECEPTION PROBLEMS (EXTERNAL TO THE TV)
• 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.
• 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.
• RADIO FREQUENCY INTERFERENCE:
The interference produces moving ripples or diagonal streaks, and in
some cases, causes loss of contrast in the picture.
