Troubleshooting
Most problems you encounter with your TV can be corrected by consulting the following troubleshooting list.
Snowy dots and interference
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.
1.
Adjust the position and orientation of the indoor/
outdoor antenna.
2.
Check the connection of antenna.
3.
Fine tune the channel.
4.
Try another channel. Broadcasting failure may
happen.
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 appliance.
Ghost
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.
Radio frequency interference
This interference produces moving ripples or diagonal
streaks, and in some case, loss of contrast in the
picture. Find out and remove the radio interference
source.
* To bring you better visual experience, please remove
all labels from TV front panel and screen before use.
