control or TV control panel and you cannot turn off the
TV, please unplug the power cords few seconds then re-

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.
The sound may be muted. Press VOLUME.
If you hear no sound, try setting the MTS feature to
Stereo mode ( page 42).
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 42).
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 42).
Remote control problems
Make sure the remote control is set to the correct device
mode ( page 20).
Remove all obstructions between the remote control and
the TV.
The remote control batteries may be dead. Replace the
batteries ( page 19).
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 21–25).
If the TV still does not act as expected, use the Reset
Factory Defaults procedure ( page 32).
