Troubleshooting

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

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 col

 setting.

2. Try another channel. Black-white program may be received.

Remote control does not work

1. Change the batteries.
2. Batteries are not installed correctly. 
3. Main power is not connected.

No picture, normal sound

1. Adjust the brightness and contrast.
2. Broadcasting failure may have occurred.

Normal picture, no sound

1. Press the 

Vol+

 button to increase volume.

2. Volume is set to mute, press the mute button to restore sound.
3. Broadcasting failure may have occurred.

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. 

Blank screen in VGA mode

Perhaps the TV can not recognize the resolution set by the PC. 
It is suggested to change to the best resolution or other standard 
resolutions of the Windows system.

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 the antenna.
3. Try another channel. Broadcasting failure may have occurred.

Ignition

Black spots or horizontal streaks appear, or the picture flutters or drifts. 
This is usually caused by interference from car ignition systems, neon 
lamps, electric drills, or other electrical appliances.

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.
