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.
