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.
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
interference from car ignition system, neon lamps,
electric drills, or other electrical appliance.
Other information
Ghost
Ghosts are caused by the television signal
following two paths. One is the direct path, the
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.
If the TV is crashed

press the Power button again to reset TV.
