Troubleshooting
If the TV seems to have a problem, first try this list of possible problems and solutions. If none of these
troubleshooting tips apply, visit “www.samsung.com”, then click on Support, or call Samsung customer
service centre.
Picture Quality
• First of all, please perform the Picture Test and confirm that your TV is properly displaying test
image. (go to MENU - Support - Self Diagnosis - Picture Test ) If the test image is properly
displayed, the poor picture may caused by the source or signal.
The TV image does not look as good as it did in the store.
• If you have an analogue cable box or satellite box, upgrade to a digital cable box or satellite box.
Use HDMI cables to deliver HD (high definition) picture quality.
• Cable/Satellite subscribers: Try digital stations from the channel line up.
• Aerial connection: Try HD stations after performing Search for channels .
• Many HD channels are up scaled from SD (Standard Definition) contents.
• Adjust the cable box or satellite box video output resolution to 1080i or 720p.
• Make sure you are watching the TV at the minimum recommended distance based on the size and
definition of the signal.
The picture is distorted: macro block, small block, dots, pixelisation error.
• Compression of video contents may cause picture distortion especially in fast moving pictures
such as sports and action movies.
• Low signal level or bad quality can cause picture distortion. This is not a TV issue.
• Mobile phones used close to the TV (cca up to 1m) may cause noise in picture on analogue and
digital TV.
There is poor colour or brightness.
• Adjust the Picture options in the TV menu. (go to Picture Mode / Colour / Brightness / Contrast /
Sharpness / Shadow detail )
• Adjust Energy saving option in the TV menu. (go to MENU - Picture - Eco settings - Energy
saving )
• Try resetting the picture to view the default picture settings. (go to MENU - Picture - Picture
Mode , then press Reset to Defaults )
There is a dotted line on the edge of the screen.
• If the picture size is set to Auto fill , change it to 16:9 Overscan .
• Change the cable box or satellite box resolution.
When changing channels, the picture freezes or is distorted or delayed.
• If connected with a cable box or satellite box, please try to reset the cable box or satellite box.
Reconnect the AC power cord and wait until the cable box or satellite box reboots. It may take up
