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.
