General troubleshooting
Before calling a service technician, please check this chapter
for a possible cause of the problem and some solutions you can
try.
Black box on-screen
• The closed caption feature is set to one of the Text modes (
T1
,
T2
,
T3
, or
T4
). Set the closed caption
feature to

page 42).
TV stops responding to controls
• If the TV stops responding to the controls on the remote
control or TV control panel and you cannot turn off the TV,
press and hold the
POWER
button on the TV control panel for
5 or more seconds to reset the TV.
Other problems
• If your TV’s problem is not addressed in this Troubleshooting

Picture problems
General picture problems
• Check the antenna/cable connections (
-
Chapter 2).
• Press
+
on the remote control or TV and select a valid video
input source (
-
page 34). 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 Chapter 2.
• 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 41).
• If you are using a VCR, make sure
L
on the remote control
is set correctly (
-
page 20).
• Do not connect both a standard video cable and an S-video
cable to the
VIDEO 1
input at the same time
(
-
page 13).
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 55).
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

VIDEO 1
,
VIDEO 2
,
ColorStream
®
,
HDMI 1
,
HDMI 2
,
HDMI 3
,
PC
or from channels 3 or 4, make sure the
Input Lock
is set
to

(
-
page 48).
Poor color or no color
• The station may have broadcast difficulties. Try another
channel.
• Adjust the
Tint
and/or
Color
(
-
page 41).
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.
• If you connect an S-video cable, be sure to disconnect the
standard (composite) video cable. Do not connect both types
of video cable at the same time.
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.
Sound problems
• Check the antenna/cable connections (
-
Chapter 2).
• The station may have 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 44).
• 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 44).
• 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 44).
