Issues Solutions and Explanations
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/set top box, upgrade to a digital set top box. Use
HDMI cables to deliver HD (high definition) picture quality.
• Cable/Satellite 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/Set top 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 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 / 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 settings. (go to MENU - Picture -
Reset Picture)
There is a dotted line on
the edge of the screen.
• If the picture size is set to Screen Fit, change it to 16:9.
• Change cable/satellite box resolution.
