Video Input Selection problems
If the Input Selection window does not appear when you press
INPUT on the remote control or TV, press INPUT a second time.
This will cause a 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 1, HDMI 2, HDMI 3 (L5200U
Series), or PC or from channels 3 or 4, make sure the Input Lock is
set to Off, see “Using the input lock feature” on page 97.
Poor display color or no color.
The station may be having broadcast difficulties. Try another
channel.
Adjust the Tint and/or Color, see “Adjusting the picture quality” on
page 80.
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.
❖Digital audio settings may not be correct. Check the
connections, see “Connecting a digital audio system” on
page 34.
❖Turn off and unplug the TV from the AC wall outlet for a few
seconds and plug it back in.
