÷ Bright portions of image
appear to be loosing
intensity.
÷ Speckles or noise appears on
screen.
÷ Stripes appear on the screen.
÷ Operation is not possible.

Note
In order to protect this unit's panels and circuitry, the revolving
speed of the interval fan will be automatically increased in order
to cool the inside of the unit when the surrounding temperature
exceeds 104 °F (40 °C). (The sound of the fan will become louder
at this time). Please operate this unit in a location with a
surrounding temperature under 104 °F (40 °C).

÷ Check the input signal compatibility chart (pages 55 and 56).
÷ Is an appropriate screen size selected? (pages 22 and 25)
÷ Adjust using SCREEN mode on the menu screen (page 38).
If there is still no improvement, this unit may be limiting the displayable range. Check the
personal computer input signal compatibility chart (pages 55 and 56).
÷ Expansion/contraction caused by surrounding temperature change may result in sound being
heard from the cabinet. This is not a malfunction.
÷ When the video input signal's level is too high, the bright portions may appear to be losing their
intensity.
Increase the adjustment level of the contrast and check the picture (page 31).
÷ May be caused by radio wave interference from appliances with motors such as hair dryers,
electric vacuum cleaners, electric power drills, ignition systems of cars, motorcycles etc., switch
devices such as thermostats etc., neon signs or electrical discharge from power lines etc..
÷ May be caused by radio wave mingling from TV station, FM station, amateur radios, public radios
(simplified radios) etc., or a nearby personal computer, TV, or video/audio component.
÷ Strong magnets in the vicinity may cause picture distortion and similar problems.
÷ External influences such as lightning strike, static electricity etc., may cause improper operation.
In this case, operate the unit after first turning the main power ON/OFF, or unplugging the power
cord and re-plugging it in after 1 to 2 minutes.
÷ Sound of fan revolving. This is not a malfunction.
Possible Solution
Additional cautions
÷ If the power is automatically turned off during operation
of this unit, the following reasons may be the cause.
1 Is the POWER SAVE mode set to "MODE1" or
"MODE2"? (page 26)
2 The surrounding temperature has risen above 104 °F
(40 °C). Please operate this unit in a location with a
surrounding temperature under 104 °F (40 °C).
3 The vents are blocked or the internal temperature
has risen abnormally due to abnormal heat
generation of internal parts etc..
If the power is automatically turned off for a reason
other than the above reasons, there could be a
malfunction. In this case, unplug the power cord from
the power outlet and request repair from your nearest
sales outlet.
÷ The plasma display panel of this unit is very bright and
viewing it a close distance will cause eye strain.
We recommend that you view the screen from a
suitable distance (9.8 to 19.7 feet (3 to 6m)).
