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.

If you hear no sound, try setting the

•
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 52).
•
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 52).
•
If you connect a PC using either the
PC IN
terminal or an
HDMI
terminal, make sure that the
PC Audio
setting is
properly set (
