Picture problems
General picture problems

select a valid video input source ( page 35). If no
device is connected to an input on the TV, no picture
appears 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 be having broadcast difficulties. Try
another channel.
• Adjust the picture quality ( page 49).
• If the Edge Booster does not achieve a sharper picture,
change the Sharpness value to increase the sharpness
level ( page 49).
Video Input Selection problems

when you press on the remote control or the
TV control panel, press a second time. The
TV displays the next video input source and the

Chapter 9: Troubleshooting
Cannot view external signals or channel
3 or 4
• If you cannot view signals from external devices
connected to
Video 1, ColorStream ® HD1, HDMI 1, HDMI 2,
HDMI 3, HDMI 4 (except 24SL415U), PC or from channel
3 or 4, ensure the Input Lock is set to Off ( page 39).
Poor color or no color
• The station may be having broadcast difficulties.
Try another channel.
• Check the Input mode when you use Shared
Inputs ( page 31).
• Adjust the Tint and/or Color ( page 49).
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,
this may occur in rare instances when viewing
certain content (e.g. television broadcasts, video
games, DVDs).
Possible causes may include, 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. Try the
following procedures:
– 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 the problem occurs only on certain TV
channels, inform your local broadcast, cable,
or satellite provider.
• The settings of Shared AV Audio and Shared PC Audio
may be not correct. Ensure the settings ( page 31).
Sound problems
• Check the antenna/cable connections ( Chapter 2).
• The station may be having 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 53).
• 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 53).
• 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 53).
• If you connect a PC using either the PC IN terminal
or an HDMI terminal, ensure that the Shared PC Audio
setting is properly set ( page 42).
