• Power is suddenly turned off.
• The system’s internal temperature has increased. Remove any objects blocking vent or clean. (See page 14.)
• Check the power control setting. (See page 33.)
• Check the sleep timer setting. (See page 43.)
• System cannot be operated.

• Are the batteries worn out? Replace with new batteries. (See page 17.)
• Are you using it under strong or fluorescent lighting?
• Is a fluorescent light illuminated to remote control sensor?
• Check if any obstacles exist between the remote control unit and the remote control sensor.
• Panel sounds/noises.
• Panel generated sounds—for example, fan motor noise, electrical circuit humming, glass panel buzzing—are
normal operation of a phosphor-based matrix display.
• When you change the Energy Save mode, you may notice a change in the panel sound. This is normal.
PICTURE/SOUND
• Screen appears dark.
• Check if any obstacles exist in front of the Room Light Sensor. (See pages 11 and 42.)
• No image and audio is presented.
• Check if the input source for video or PC has been unintentionally selected although you want to watch a TV channel.
(See page 19.)
• Check if you have selected a channel blocked with Channel Lock. (See page 26.)
• Enter a password to temporarily cancel Channel Lock. (See page 44.)
• Check the cable connection with the antenna. (See page 16.)
• Check the cable connection with the other equipment. (See pages 45 to 49.)
• No picture.
• Is connection to other components correct? (See pages 45 to 49.)
• Is a non-compatible PC signal being input? (See page 47.)
• Sound is reversed between the right

• Sound is output from only a single
speaker.
• Check if the speaker cable connections have been reversed between the right and left or if the speaker cable from
either speaker has been disconnected. (See page 12.)
• Has the balance been correctly adjusted? (See page 32.)
• Audio is output but no image is
presented.

+
/
i
–
or

. (See page 34.)
• Images are presented but no audio is

colour misalignment.
• Adjust the picture tone. (See pages 28 to 31.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See page 41.)
• After-image lag.
• After displaying a still image or a very bright image for a certain period of time, if the screen is then switched to a
darker scene, the previous image may appear as an after-image.
• This can be rectified by playing a rather bright moving image for several minutes. However, displaying a still image
for excessively long periods of time may cause permanent display deterioration.
• You can display the “Video Pattern” screen that helps eliminate after-image when it occurs. (See page 43.)
• It is also recommended to select “Screen Protection”. (See page 43.)
• Brightness and colour tone on both
sides differ from those in the centre in 4:3
mode.
• If images in 4:3 mode or letterbox images are displayed for long periods or for shorter periods over several days, an
after-image may remain due to burning. This is a characteristic of plasma displays.
• We recommend that you enjoy watching images in a full screen mode as much as possible. (See page 41.)
• We recommend you select “Auto” for “Brightness Sync.” in the Side Mask setting. This adjusts the brightness of the
grey side masks according to the brightness of the main image. (See page 42.)
• It is also recommended to select “Screen Protection”. (See page 43.)
