6. TROUBLESHOOTING
6.1 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 cases, 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, power off
the TV (or unplug AC cord). After 10 minutes, turn on the main power(or plug in AC cord). Repeat the above
process until improper color disappear.
