2. Plug another electrical device into the
outlet to make sure it is working or turned
on.
3. Poor power plug contact with the outlet.
4. Check the signal source.
NO COLOR

may be received.

NORMAL PICTURE, NO SOUND
1. Press the volume up button to increase
volume.
2. Volume is set to mute, press MUTE to
restore sound.
3. Change the sound system.
4. Broadcasting failure may happen.
UNORDERLY RIPPLES ON THE PICTURE
It is usually caused by local interference, such
as cars, daylight lamps and hair dryers. Adjust
the antenna to minimize the interference.
BLANK SCREEN IN PC MODE
(only for models with PC terminals)
Perhaps the TV cannot recognize the PC set
resolution. Choosing the best resolution or
other standard resolutions for the Windows
system is recommended. Set refresh rate to
60Hz.
SNOWY DOTS AND INTERFERENCE
If the antenna is located in the fringe area of
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
which follows two paths. One is the direct
path, the other is reflected off 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 cases, loss of
contrast in the picture. Detect and remove
the radio interference source.
Note :
If the problem persists after applying the
solutions, please contact your local support
centre.
