Explanation/Solution
• Picture quality depends on the signal content. See Quick Setup Guide
(supplied) to display the best possible picture for that signal.
• Content and signal quality are controls 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.
• Check cable/antenna connections.
• Check the antenna location and direction.
• Check if the antenna is broken or bent.
• Check if the antenna has reached the end of its serviceable life. (3-5 years
in normal use, 1-2 years at the seaside.)
• 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.
• Adjust the Picture Mode options in the Picture settings (see page 29).
• If you set the Power Saving mode to Low or High, it will enhance the
black level.
• Make sure that the antenna is connected using a 75-ohm coaxial cable
(not supplied).
• Keep the antenna cable away from other connecting cords.
• To avoid TV interference, make sure to use an undamaged antenna cable.
• Transporting the TV from a cold to a warm location or a sudden change
in room temperature may cause moisture condensation, resulting in a
blurry picture or poor color. Turn off your TV and wait a few hours
before powering on again.
• Check the volume control.
• Press MUTING or VOL + so that "Muting" disappears from the screen (see
page 21).
• Set Speakers to TV Speakers in the Sound settings (see page 32). If
it is set to Audio System, sound is not output from the TV's speakers
regardless of the TV's volume control.
• When using HDMI input with Super Audio CD or DVD-Audio,
DIGITAL AUDIO OUT (OPTICAL) may not provide an audio signal.
• When tuned to a digital channel with Alternate Audio, the broadcaster
may not be broadcasting your preferred Alternate Audio language.
Press OPTIONS, highlight and select Alternate Audio, and change the
Alternate Audio language (see page 32).
• Make sure that the antenna is connected using a 75-ohm coaxial cable
(not supplied).
• Keep the antenna cable away from other connecting cords.
• To avoid TV interference, make sure to use an undamaged antenna cable.
• Set Speakers to Audio System in the Sound settings (see page 32).
• Verify that the Video1/Component Selection (see page 40) is set to
the current input type in use. We suggest leaving this setting to Auto.
