• Some functions and pictures shown in this manual are available on specific models only.
• You can keep your TV in optimum operating condition by upgrading to the latest firmware (www.samsung.com >
support) by USB.
• This TFT LED panel uses a panel consisting of sub pixels which require sophisticated technology to produce.
However, there may be a few bright or dark pixels on the screen. These pixels will have no impact on the
performance of the product.
Poor picture
First of all, please perform the Picture Test and confirm that your TV is properly displaying the test image.
• Go to MENU > Support > Self Diagnosis > Picture Test
If the test image is properly displayed, the poor picture may be caused by the source or signal.
The TV image does not look as good as it did in the store.
• If you have an analog cable or satellite box, upgrade to a digital set top box. Use HDMI or Component cables to
deliver HD (high definition) picture quality.
• Cable or satellite box subscribers: Try HD 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 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: macroblock error, small block, dots, pixelization.
• Compression of video contents may cause picture distortion, especially in fast moving pictures such as sports
and action movies.
• Low signal level can cause picture distortion. This is not a TV problem.
• Mobile phones used close to the TV (up to 1 m) may cause noise in picture on analog and digital TV.
Color is wrong or missing.
• If you're using component connection, make sure the component cables are connected to the correct jacks.
Incorrect or loose connections may cause color problems or a blank screen.
There is poor color or brightness.
• Adjust the Picture options in the TV menu. (Go to Picture Mode / Color / Brightness / Sharpness)
• Adjust Energy Saving option in the TV menu (Go to MENU > System > Eco Solution > Energy Saving)
• Try resetting the picture to view the default picture setting. (Go to MENU > Picture > Reset Picture)
