Troubleshooting
Before you call for service, determine the symptoms and make a few simple checks as shown below.

If  a  signal  with  a  non-applicable  color  system  format,  or  frequency  is  input,  only  the  input 
terminal indication is displayed.
No ColorNormal Sound Color controls set at minimum level. (see page 24)
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	 fluorescent	
light.
Check
 	whether	 the	remote	 control	designed	 specifically	 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.
This Plasma 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.
Plasma Display panel
Symptoms Check
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 or when the images for the main picture 
and sub picture on the two screens are swapped.
The

	edges	of	the	images	flicker. Due	to 	the 	characteristics 	of 	the 	system 	used 	to 	drive 	the 	panel, 	the 	edges 	may 	appear 	to 	flicker	
in the fast-moving parts of the images: This is normal and not indicative of malfunctioning.
The brightness on both sides of images in 4:3 mode 
changes. When viewing the side panels at the “BRIGHT” or “MID” setting, the brightness on both sides 
may  change  depending  on  the  kind  of  program  shown:  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	fine	picture	 details.	 Occasionally,	 a	few	
non-active	pixels	may	appear	on	the	screen	as	fixed	points	of	red,	blue,	green,	or	black.
Please note this does not affect the performance of your Plasma Display.
Example
Image retention appears Image  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.
