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

utters 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 reected

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.

* To bring you better visual experience, please remove

all labels from TV front panel and screen before use.

No picture, no sound

1. Check if the fuse or circuit breaker is working.

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.

No color

1. Change the color system.

2. Adjust the saturation.

3. Try another channel. Black-white program may be

received.

Remote control does not work

1. Change the batteries.

2. Batteries are not installed correctly.

No picture, normal sound

1. Adjust the brightness and contrast.

2. Broadcasting failure may happen.

Normal picture, no sound

2. Volume is set to mute, press the MUTE button to

restore sound.

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.
