Video Input Selection problems.
If the Input Selection window does not appear when you press the
INPUT button on the remote control or the TV control panel, press
the INPUT button a second time. The TV displays the next video
input source and the Input Selection screen.
Cannot view external signals or channel 3 or 4.
If you cannot view signals from external devices connected to
VIDEO 1, VIDEO 2, ColorStream HD1, ColorStream HD2, HDMI
1, HDMI 2, HDMI 3, HDMI 4, PC, or from channel 3 or 4, ensure
that the Input Lock is set to Off, see “Locking video inputs” on
page 96.
Poor display color or no color.
The station may be having broadcast difficulties. Try another
channel.
Check the Input mode when you use Shared Inputs, see
“Configuring shared inputs” on page 70.
Adjust the Tint and/or Color, see “ColorMaster™” on page 121.
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). The cause 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:
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.
