daylight lamps and hair driers. Adjust the antenna to
minimize the interference.
Snowy dots, blocking 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, show blocking or break-ups. 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. Fine tune the channel.
4. Try another channel. Broadcasting failure may
happen.
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.
Playback of video is causing picture freeze/
macro blocks or similar distortion, especially
