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 (L_÷Chapter 2).
The station may have broadcast difficulties. Try
another channel.
The sound may be muted. Press VOLUME.
If you hear no sound, try setting the MTS feature
to Stereo mode (L_÷page 40).
If you are not receiving a second audio program
from a known SAP source, make sure the MTS
feature is set to SAP mode (_. page 40).
If you hear audio that seems "incorrect" for the
program you are watching (such as music or a
foreign language), the SAP mode may be on. Set
the MTS feature to Stereo mode (_. page 40).
Remote control problems
,, Remove all obstructions between the remote
control and the TV.
,, The remote control batteries may be dead.
Replace the batteries (L_÷page 21 ).
,, if the TV still does not act as expected, use the
Reset Factory Defaults procedure (_a_. page 29).
Channel tuning problems
,, The channel may be locked by the Channel
Options feature. Unlocked the channel (_a_. page 44).
,, if you are unable to tune digital channels, check
the antenna configuration (_. page 26). If you
are still unable to tune digital channels, use the
Reset Factory Defaults procedure (_a_. page 29).
