08 Troubleshooting and Maintenance
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
• First of all, please perform the Picture Test and confirm that your TV is properly displaying test image.
(go to MENUm - 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
or Component 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 Auto tuning.
• 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.
Colour is wrong or missing.
• If you're using a component connection, make sure the component cables are connected to the correct
jacks. Incorrect or loose connections may cause colour problems or a blank screen.
