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.



The station may have broadcast difﬁculties. Try another

channel.

MTS

feature is set to

SAP



page 36,37).

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 36,37).

Remote control problems

Make sure the remote control is set to the correct device

mode (



page 21).

Remove all obstructions between the remote control and

the TV.

The remote control batteries may be dead. Replace the

batteries (



page 20).

Your TV remote control may not operate certain features

on your external device. Refer to the owner’s manual

for your other device to determine its available features.

If your TV remote control does not operate a speciﬁc

feature on another device, use the remote control that

came with the device (



pages 22–26).

Channel tuning problems

Make sure the remote control is set to the correct device

mode (



page 21).

unable to tune digital channels, clear all channels from

the channel list (
