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/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 external A/V device (e.g., DVD player, video
game system, set-top-box, etc.) always try to use the Color Stream video
jacks and corresponding audio jacks or the HDMI input (if available on your
TV) for connection to such external A/V device.
• 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 connected to a video game system and your TV has the Game Mode
feature (see owner's manual for more information), enable this feature.
• If you notice this phenomenon only on cetain 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.
• Check the antenna connections.
• Make sure TV/CABLE is set to CABLE mode.
• The channel may be blocked by the V-Chip feature or CH LOCK feature, or
erased with the add/erase feature.
• Check the VIDEO LOCK feature.
• The station may have broadcast difficulties. Try another channel.
• Use a highly directional outdoor antenna.
• The station may have broadcast difficulties. Try another channel.
• Adjust the TINT and/or COLOR in the PICTURE menu.
• Select OFF in the Closed Caption menu to turn off the Closed Caption Text
mode.
• Make sure the MTS feature is set properly (AUDIO menu).
• Change or reset your password.
• Remove all obstructions between the remote control and the TV.
• The remote control batteries may be dead. Replace the batteries.
• Check the PANEL LOCK feature.
