Troubleshooting
Most problems you encounter with your TV can be
corrected by consulting the following troubleshooting list.

2. Plug another electrical device into the outlet to make
sure it is working or turned on.
3. Power plug is in a bad contact with the outlet.
4. Check the signal source.

Normal picture, no sound
It is usually caused by local interference, such as cars,
daylight lamps and hair driers. Adjust the antenna to
minimize the interference.
Unorderly ripples on the picture
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.

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.
Snowy dots and interference
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.
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.
Ignition
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.
