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
AN
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.
Scrolling text problem
• When slow motion video is present the units will
treat any scrolling text as Film and may cause a
slight
jitter
of
the scrolling text. Turning
Off
the
Film
Stabilization
feature will correct this issue.
