Unorderly
ripples on the

Adjust the antenna to minimize the interference.
Blank screen in
pc mode
Perhaps the TV cannot recognize the resolution set by the PC. Suggest changing
to the best resolution or other standard resolutions of Windows system. Set refresh
rate to be 60 Hz.
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.
