The picture is distorted.
The compression of video content may cause picture distortions, especially in fast moving
pictures from sports programs and action movies.
If the signal reception is weak or poor, screen distortion may be visible but it is not a
malfunction.
Mobile phones used close to the TV (within 3.2 ft) may cause noise on analog and digital
channels.
The color is wrong or
missing.
If you’re using a Component connection, make sure that the Component cables are connected
to the correct jacks.
Incorrect or loose connections may cause color problems or a blank screen.
