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 color
1. Change the color 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 Vol+ button to increase volume.
2. Volume is set to mute, press the mute button 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 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. Suggest 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.
Other Information
1. Adjust the position and orientation of the indoor or
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.
