PROBLEMS OF PICTURE
The most common types of picture problems are as follows:
IGNITION
Black spots or horizontal streaks appear, or the picture flutters or drifts. This is usually caused
by interference from car ignition system, neon lamps, electric drills, or other electrical appliances.
GHOSTS
Ghosts are caused by the television signal following two paths. One is the direct path, 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 the antenna is located in the fringe area of a television signal where the signal is weak, the picture
may be marred by dots. When the signal is extremely weak, it may be necessary to install a special
antenna to improve the reception.
RADIO FREQUENCY
INTERFERENCE
This interference produces moving ripples or diagonal streaks, and in some case, loss of contrast in
the picture.
CRT DEGAUSSING
If the TV screen has been magnetized with improper color appearing on the particular area of screen,
please power off the TV (or unplug AC cord), after 10 minutes, then turn on the main power (or plug in
AC cord), repeat the above process until the improper color disappear.
