Chapter 12: Troubleshooting
General troubleshooting (continued)
Picture problems (continued)
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, DVD), 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 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.
“Now Booting” message appears on-screen
• If you unplug the power cord, when you plug the power cord in again the message “Now Booting...” will display on-screen until the
picture appears or the green LED will blink until the TV enters standby mode. This is normal and is not a sign of malfunction.
Sound problems
• Check the antenna/cable connections (see 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 90).
• Make sure the Speakers function in the Audio Setup menu is set correctly (page 93).
• 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 90).
• 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 90).
•When using an external audio amplifier, if you connect the amplifier to the VAR. AUDIO OUT terminals, the volume of the TV and
amplifier must be set above 0 or you will not hear any sound (page 24).
Remote control problems
• Make sure the remote control is set to the correct device mode (page 33).
• Remove all obstructions between the remote control and the TV.
•The remote control batteries may be dead. Replace the batteries (page 33).
•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 (page 33).
• If the TV still does not act as expected, use the Restore Factory Defaults procedure as described on page 57.
Channel tuning problems
• Make sure the remote control is set to the correct device mode (page 33).
•The channel may have been erased from the channel memory by the Channel Add/Delete feature. Add the channel to the channel
memory (page 48).
•The channel may be blocked by the Channels Block feature. Unblock the channel (page 99).
• If you are unable to tune digital channels, check the antenna configuration (page 46). If you are still unable to tune digital channels,
clear all channels from the channel list (page 48) and reprogram channels into the channel memory (page 47). If you are still unable to
tune digital channels, use the Restore Factory Defaults procedure as described on page 57. Also see “TV stops responding to
controls” and “Other problems” on the next page.
Closed caption problems
• If the program or video you selected is not closed-captioned, no captions will display on-screen (page 88).
• If text is not available, a black rectangle may appear on-screen. If this happens, turn off the closed caption feature (page 88).
•A closed caption signal may not display correctly in the following situations: a) when a videotape has been dubbed; b) when the
signal reception is weak; or c) when the signal reception is nonstandard (page 88).
Rating blocking (V-Chip) problems
• If you forget your PIN code: While the PIN code entering screen is displayed, press RECALL four times within 5 seconds. The PIN
code you previously stored will be cleared (page 98).
•The V-Chip feature is available for the U.S. V-Chip system only (page 99).
