Troubleshooting
Before you call for service, determine the symptoms and make a few simple checks as shown below.
Symptoms
Checks
Picture Sound
InterferenceNoisy SoundElectrical Appliances
Cars / Motorcycles
Fluorescent light
Normal PictureNo SoundVolume
(Check whether the mute function has been activated on the remote control.)
No PictureNo SoundNot plugged into AC outlet
Not switched on
PICTURE and BRIGHTNESS/Volume setting
(Check by pressing the power switch or stand-by button on the remote control.)
No PictureNormal SoundIf a signal with a non-applicable color system format, or frequency is input, only the input 
terminal indication is displayed.
No ColorNormal SoundColor controls set at minimum level. (see page 27, 28)
COLOR SYSTEM (see page 42)
No remote control operations can be performed.
Check whether the batteries have discharged completely and, if they have not, whether they were 
inserted properly.
Check whether the remote control sensor is exposed to an outdoor light or a strong 	 uorescent light.
Check whether the remote control designed speci cally for use with the unit is being used. (The unit 
cannot be operated by any other remote control.)
A cracking sound is sometimes heard from the unit. If there is nothing wrong with the picture or sound, this is the sound of the cabinet undergoing 
very slight contractions in response to changes in the room temperature.  There are no adverse 
effects on the performance or other aspects.
The top or bottom of the picture on the screen is cut 
off when I use the zoom function.Adjust the position of the picture on the screen.
Areas at the top and bottom of the screen where 
the image is missing appear when I use the zoom 
function.When using a video software program (such as a cinema size program) with a screen wider 
than one in the 16:9 mode, blank areas separate from the images are formed at the top and 
bottom of the screen.
I can hear sounds coming from inside the unit. When the power is turned on, a sound of the display panel being driven may be heard: This is 
normal and not indicative of malfunctioning.
Parts of the unit become hot.Even when the temperature of parts of the front, top and rear panels has risen, these temperature 
rises will not pose any problems in terms of performance or quality.
Power automatically turns off unexpectedly. Check the settings of “NO SIGNAL POWER OFF”, “PC POWER MANAGEMENT”, 
“DVI-D POWER MANAGEMENT” and “NO ACTIVITY POWER OFF”. Any of them may be 
set to “ON (ENABLE)”. (see page 34, 35)
There is no picture displayed or sound output 
sometimes.When HDMI or DVI signals are input to the Display using a selector or distributor, sound 
or images may not be output in the normal fashion depending on the selector or distributor 
used.
The symptoms may be improved by turning the power off and on again, or by replacing the 
selector or distributor.
This LCD Display uses special image processing. Hence a slight time lag may occur between image and audio, depending on the type of input signal. 
However, this is not a malfunction.
LCD Display panel
Symptoms Check
The screen darkens slightly when bright pictures with 
minimal movements are shown.The screen will darken slightly when photos, still images of a computer or other pictures with minimal 
movements are shown for an extended period. This is done to reduce image retention on the screen 
and the shortening of the screen’s service life: It is normal and not indicative of malfunctioning.
It takes a while for the picture to appear. The unit digitally processes the various signals in order to reproduce esthetically pleasing 
images. As such, it sometimes takes a few moments for the picture to appear when the power 
has been turned on, when the input has been switched.
The  edges  of  the  images  	 icker. Due to the characteristics of the system used to drive the panel, the edges may appear to 	 icker 
in the fast-moving parts of the images: This is normal and not indicative of malfunctioning.
There may be red spots, blue spots, green spots and 
black spots on the screen.This is a characteristic of liquid crystal panels and is not a problem. The liquid crystal panel 
is built with very high precision technology giving you  ne picture details. Occasionally, a few 
non-active pixels may appear on the screen as  xed points of red, blue, green, or black. Please 
note this does not affect the performance of your LCD.
Image retention appearsImage retention may occur. If you display a still picture for an extended period, the image 
might remain on the screen. However, it will disappear after a while. This is not considered 
as malfunction.
