Troubleshooting

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

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.

all labels from TV front panel and screen before use.
