TROUBLESHOOTING

Before calling a service technician, review following information for possible causes and
solutions for the problem you are experiencing.
NO PICTURE, NO SOUND
1. 1. Check if the fuse or circuit breaker is
working.
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
1. Change the colour system.
2. Adjust the saturation.
3. Try another channel. Black-white program
may be received.
REMOTE CONTROL DOES NOT WORK
1. Change the batteries.
2. Batteries are not installed correctly.
3. Main power is not connected.
NO PICTURE, NORMAL SOUND
1. Adjust the brightness and contrast.
2. Broadcasting failure may happen.
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.
