Poor picture

Picture quality not as good as
viewed at the store

• Picture quality depends on the signal content. See Quick Setup Guide

(supplied) to display the best possible picture for that signal.

Broadcast HD formats have
poor quality

• Content and signal quality are regulated by the signal provider. Many HD

channels and content are actually upscaled versions of standard-definition
broadcasts. The picture is affected by the quality of the signal received, which
varies between channel and program.

• Confirm the picture quality by selecting Signal Diagnostics in the Product

Support settings (page 40). Then select Sample Image (or Additional
first). An HD image will display on the screen to confirm routine
panel operation. If your normal picture quality is worse than this sample image,
it is most likely due to the signal provided by the broadcaster.

Double images or ghosts

• Check the antenna location and direction.
• Set the Motion Enhancer to Standard or Off (see page 42).

Only snow and noise appear
on the screen

• Check if the antenna has reached the end of its serviceable life. (3-5 years in

normal use, 1-2 years at the seaside.)

Dotted lines or stripes

• Keep the TV away from noise sources such as cars, motorcycles, or hair-dryers.
• If using 300 ohm twin lead, move the excess lead away from the TV or try using

75 ohm coaxial cable instead.
