Troubleshooting
Most problems you encounter with your TV can be corrected
by consulting the following troubleshooting list.
No picture, no sound
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. Power plug is in a bad contact with the outlet.
4. Check the signal source.
No colour
1. Adjust the colour setting.
2. 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 have occurred.
Normal picture, no sound
1. Press the volume up button to increase volume.
2. Volume is set to mute, press the mute button to restore sound.
3. Broadcasting failure may have occurred.
Unorderly ripples on the picture
It is usually caused by local interference, such as cars, daylight
lamps and hair driers. Adjust the antenna to minimize the
interference.
Blank screen in VGA mode
Perhaps the TV can not recognize the resolution set by the PC.
It is suggested to change to the best resolution or other standard
resolutions of the Windows system.
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 the antenna.
3. Try another channel. Broadcasting failure may have occurred.
Ignition
Black spots or horizontal streaks appear, or the picture flutters
or drifts. This is usually caused by interference from car ignition
systems, neon lamps, electric drills, or other electrical appliances.
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.
