Picture Issues
When the TV has a picture problem, these steps may help resolve the problem.
Press / button on your remote control and select Settings > Support > Self Diagnosis > Picture
Test.
Before you review the list of problems and solutions below, use Picture Test to determine if the problem is
caused by the TV. Picture Test displays a high definition picture that you can examine for flaws or faults.
• If the test picture does not appear or there is noise or distortion, the TV may have a problem. Contact the
service company in your country/region.
• If the test picture is displayed properly, there may be a problem with an external device. Please check the
connections.
• If the problem persists, check the signal strength or refer to the external device's user manual.
Problem Possible Solutions
The picture is distorted.
• The compression of video content may cause picture distortions,
especially in fast moving pictures from sports programmes 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 1m) may cause noise on
analogue and digital channels.
The picture is blurry or
flickering, or cuts out
momentarily.
•
Press / button on your remote control and select Settings >
Picture > Picture Mode Settings > Sharpness. You can try to increase
or decrease the Sharpness.
• If you use an external antenna, check the direction, position and
connection of the antenna.
• Adjust the direction of your antenna, or reset or fine tune the channel.
