TROUBLESHOOTING
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 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 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.
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.
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 PC 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 Windows system.
Set refresh rate to be 60Hz.
