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.
