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 gaines, 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 serum 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 FilmStabilizationfeature will correct this issue.
