Check the antenna/cable connections ( Chapter
on the remote control or TV and

Chapter 9: Troubleshooting

Noisy picture
If you are watching an analog channel (off-
air broadcast or Cable TV), you can set the
feature to reduce visible interference
in the TV picture ( page 63).
Video Input Selection problems
If the Input Selection window does not appear
when you press
on the remote control or
TV, 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
HDMI 2, HDMI 3, HDMI 4, PC or from channels 3 or 4,
make sure the Input Lock is set to Off ( page 52).
Poor color or no color
The station may have broadcast difficulties. Try
another channel.
Adjust the Tint and/or Color ( page 46).
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.
Scrolling text problem
When slow motion video is present the unit will
treat any scrolling text as Film and may cause a
slight jitter of the scrolling text. Turning Off the
Film Stabilization feature will correct this issue.
