Issues Solutions and Explanations
The picture is distorted:
macroblock error, small
block, dots, pixelization. • The compression of video contents may cause picture distortion,
especially in fast moving pictures such as sports and action movies.
• A weak signal can cause picture distortion. This is not a TV problem.
• Mobile phones used close to the TV (within 3.3 ft) may cause noise
in the picture on analog and digital channels.
Color 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 color problems or a blank screen.
