General picture problems
•
Check the antenna/cable connections (
-
Installation
Guide
).
•
Press
+
on the remote control or TV and select a valid
video input source (
-
page 23). 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 the
Installation Guide
.
•
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 30).
•
If you are using a VCR, make sure
L
on the remote
control is set correctly (
-
page 11).
•
If you have two VCRs connected to your TV, make sure
you have not connected the same VCR to the TV’s output
and input connections at the same time (
-
Installation
Guide
).
•
Do not connect both a standard video cable and an S-
video cable to the
VIDEO 1
input at the same time
(
-
Installation Guide
).
Noisy picture
•
If you are watching an analog channel (off-air broadcast
or Cable TV), you can set the
CableClear
®
/DNR
feature to
AUTO
to reduce visible interference in the TV
picture (
-
page 42).
Video Input Selection problems

ColorStream
®
connections.
Poor composite or S-video 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.
LED indications while in reboot from standby
•
When you plug the power cord in, the yellow LED will
blink until the TV enters standby mode, (plugged in but
not powered on). This is normal and is not a sign of
malfunction.
