No Picture

Normal Sound

If a signal with a non-applicable color system format, or frequency is input, only the input 
terminal indication is displayed.

No Color

Normal Sound

Color controls set at minimum level. (see page 29-34)
COLOR SYSTEM (see page 45)

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 “PC POWER MANAGEMENT”, “DVI-D POWER MANAGEMENT”, “NO 
SIGNAL POWER OFF” and “NO ACTIVITY POWER OFF” in the SETUP menu. Any of them 
may be set to “ON (ENABLE)”. (see page 42)

Power indicator is blinking in red.

There is possibility of malfunction. Please contact an Authorized Service Center.

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

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.

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.

Some parts of the screen do not light up.

The plasma display panel is manufactured using an extremely high level of precision technology, 
however, sometimes some parts of the screen may be missing picture elements or have luminous 
spots. This is not a malfunction.

Image retention appears

Do not allow a still picture to be displayed for an extended period, as this can cause a permanent 
image retention to remain on the Plasma Display.
Examples of still pictures include logos, video games, computer images, teletext and images 
displayed in 4:3 mode.

Note:

The permanent image retention on the Plasma Display resulting from  xed image use is not 
an operating defect and as such is not covered by the Warranty.
This product is not designed to display  xed images for extended periods of time.

Whirring sounds can be heard from the display unit.

The display unit is  tted with a cooling fan to dissipate heat generated during normal use. The 
whirring sound is caused by rotation of the fan and is not a malfunction.
