Chapter 8: Troubleshooting
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 (T1T2T3, or T4). Set the Closed Caption 
feature to Off (- page 41).
LED indications while in reboot from standby
When you plug the power cord in the red 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.
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 section or the recommended solution 
has not worked, use the Reset Factory Defaults procedure 
(- page 29).
TV will not turn on
Make sure the power cord is plugged in, and then 
press p.  
The remote control batteries may be dead. Replace the 
batteries or try the control panel buttons.
Picture problems
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 30). 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 40).
If you are using a VCR, make sure L on the remote 
control is set to the correct mode (see item 23 on page 
12).
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 same set of VIDEO inputs 
(VIDEO 1, or VIDEO 2) at the same time 
(- Installation Guide).
Noisy picture
If you are watching an tuned analog channel (off-air 
broadcast or Cable TV), you can set the CableClear
®
 
feature to AUTO to reduce visible interference in the TV 
picture (- page 53).
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 1VIDEO 2, or ColorStream
®
, or 
from channels 3 or 4, make sure the Input Lock is set to 
Off (- page 48).
Poor color or no color
The station may have broadcast difficulties. Try another 
channel. 
Adjust the Tint and/or Color (- page 40).
When the ColorStream
®
 signal source is active, the 
VIDEO OUT terminal does not output video. To receive 
video from the VIDEO OUT terminal, a standard video 
or S-video IN connection must be used instead of the 
ColorStream
®
 connections.
POP problems
If you label all of the inputs as “Hide,” the POP feature 
will be disabled. If you then attempt to access the POP 
feature, the message “Not Available” will appear on-
screen (- page 38).
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.
