Chapter 8: Troubleshooting
Picture brightness changes soon after turning on TV
• If you set the lamp mode to Low Power, each time you
turn on the TV, the lamp will start out in High Bright
mode but will switch to Low Power mode after a short
period of time. You may notice a change in screen
brightness when this happens. This is normal and is not a
sign of malfunction (- page 55).
Poor composite or S-video picture
• If the TV is connected to an external A/V device (e.g.,
DVD player, video game system, set-top box, etc.) try
using a ColorStream or HDMI video connection
instead.
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 (- Installation
Guide).
• The station may have broadcast difficulties. Try another
channel.
• The sound may be muted. Press z.
• If you hear no sound, try setting the MTS feature to
Stereo mode (- page 45).
• Make sure the Speakers function in the Audio Setup
menu is set correctly (- page 46).
• 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 45).
• 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 45).
• 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 (- Installation Guide).
Remote control problems
• Make sure the remote control is set to the correct device
mode (- page 16).
• Remove all obstructions between the remote control and
the TV.
• The remote control batteries may be dead. Replace the
batteries (- page 11).
• 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 16).
• If the TV still does not act as expected, use the Reset
Factory Defaults procedure (- page 31).
Channel tuning problems
• Make sure the remote control is set to the correct device
mode (- page 16).
• The channel may have been erased from the channel
memory by the Channel Add/Delete feature. Add the
channel to the channel memory (- page 27).
• The channel may be blocked by the Channels Block
feature. Unblock the channel (- page 49).
• If you are unable to tune digital channels, check the
antenna configuration (- page 25). If you are still
unable to tune digital channels, clear all channels from
the channel list (- page 27) and reprogram channels into
the channel memory (- page 26). If you are still unable
to tune digital channels, use the Reset Factory Defaults
procedure (- page 31). Also see “TV stops responding
to controls” and “Other problems” (- page 76).
Closed caption problems
• If the program or video you selected is not closed-
captioned, no captions will display on-screen
(- page 43).
• If text is not available, a black rectangle may appear on-
screen. If this happens, turn off the closed caption feature
(- page 43).
• 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 43).
Rating blocking (V-Chip) problems
• If you forget your PIN code: While the PIN code entering
screen is displayed, press
E four times within 5
seconds. The PIN code you previously stored will be
cleared (- page 47).
• The V-Chip feature is available for the U.S. V-Chip
system only (- page 48).
