Chapter 11: Troubleshooting
General troubleshooting
Before calling a service technician, please check
this chapter for a possible cause of the problem
and some solutions you can try.
Black box on-screen
•
The closed caption feature is set to one of the
Text modes (T1, T2, T3, or T4). Set the closed
caption feature to Off ( Page 39).
TV stops responding to controls
•
If the TV stops responding to the controls on
the remote control or TV control panel and you
cannot turn off the TV, press and hold
POWER on the TV control panel for 5 or more
seconds to reset the TV.
• If you cause a static discharge when touching
the TV and the TV fails to function, simply
unplug the TV from the AC outlet and plug it
back in. The TV should return to normal
operation.
Other problems
•
If your TV’s problem is not addressed in this
Troubleshooting section or the recommended
solution has not worked, use the Reset
Factory Defaults procedure ( Page 32).
TV will not turn on
•
Make sure the power cord is plugged in, and
then press POWER.
• The remote control batteries may be dead.
Replace the batteries or try the control panel
buttons.
Picture problems
General picture problems
• Check the antenna/cable connections (
Chapter 2).
• Press on the remote control or the TV and
select a valid video input source ( Page
33). If no device is connected to a particular
input on the TV, no picture will display when
you select that particular input source. For
device connection details, see Chapter 2.
• Antenna reception may be poor. Use a highly
directional outdoor antenna (if applicable).
• The station may have broadcast difficulties.
Try another channel.
• Adjust the picture qualities ( Page 38).
Video Input Selection problems
• If the Input Selection window does not
appear when you press on the remote
control or the TV control panel, press a
second time, which will change to the next
video input source and display the Input
Selection window.
Cannot view external signals or channel 3 or 4
• If you cannot view signals from external
devices connected to Video, ColorStream
HD, HDMI 1, HDMI 2, PC or from channels 3
or 4, make sure the Input Lock is set to Off
( Page 45).
Noisy picture
• If you are watching an analog channel (off-air
broadcast or Cable TV), you can set the
CableClear
®
feature to reduce visible
interference in the TV picture ( Page 51).
Poor color or no color
• The station may have broadcast difficulties.
Try another channel.
• Adjust the Tint and/or Color ( Page 38).
Poor composite 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 (
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 41).
• 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 41).
• 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 41).
• If you connect a PC using either the PC IN
terminal or an HDMI terminal, make sure that
the PC Audio setting is properly set ( Page
46).
Remote control problems
•
Remove all obstructions between the remote
control and the TV.
• The remote control batteries may be dead.
Replace the batteries ( Page 24).
