RECEPTION PROBLEMS 

 

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.

This Projection Television incorporates advanced power surge protection technology
