directional outdoor antenna (if applicable).

another channel.

an S-video cable to the VIDEO 1 input at the
same time ( page 14).
Chapter 8: Troubleshooting
Noisy picture
• If you are watching an analog channel (off-air

CableClear ®
feature to reduce visible interference in the TV picture
( page 54).

you press
on the remote control or TV, press
a second time, which will change to the next video
input source and display the Input Selection window.
Cannot view external signals or channel 3 or 4

Input Lock is set to Off ( page 48).
Poor color or no color

another channel.
• Adjust the Tint and/or Color ( page 42).
Poor composite or S-video picture
• If the TV is connected to an external A/V device
(e.g., DVD player, video game system, set-top
box, etc.) try using a ColorStream or HDMI video
connection instead.
Picture and sound are out of sync
• As with all products that contain a digital display,
in rare instances, when viewing certain content
(e.g.. television broadcasts, video games, DVDs),
you may notice that the sound and picture are
slightly out of sync. This phenomenon can be
caused by various factors including, without
limitation, video processing within the TV, video
processing in an attached gaming system, and
video processing or different compression rates
used by broadcasters in their programming. You
may want to try one or more of the following
suggestions, which may help to reduce the effect
of this phenomenon:
– If the TV is connected to an A/V receiver that
has a programmable audio delay feature, use
this feature to help synchronize the sound to the
picture.
– If you notice this phenomenon only on certain
TV channels, please contact your local broadcast,
cable, or satellite provider to inform them of this
issue.
Sound problems
• Check the antenna/cable connections
( Chapter 2).
• The station may have broadcast difficulties. Try
another channel.
