Press 

 on the remote control or TV and 

select a valid video input source ( page 38). 
If no device is connected to a particular input

Antenna reception may be poor. Use a highly 
directional outdoor antenna (if applicable).

The station may have broadcast difficulties. Try 
another channel.

Adjust the picture qualities ( page 46).

 

•

If you are watching an analog channel (off-

•

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.

 

•

When slow motion video is present the unit 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.
