Burn-in
A characteristic of Plasma Display Panels (PDPs) is that displaying the same image for a long time
causes a part of the image to stay on the screen (this is called phosphor burn-in).
Avoid burn-in as follows.
„
Use the PICTURE SHIFT function. To prevent burn-in, the picture displayed on the
screen is shifted up, down and to the left and right at regular intervals. See page 44
for details.
• Even if the PICTURE SHIFT function is turned off, the picture may shift to the left or right when
the channel or input is changed.
„
The PICTURE MODE function is initially set to BRIGHT. Unless the TV is being
watched in an extremely bright room, we recommend you change the PICTURE
MODE setting to either STANDARD or SOFT. Doing so will reduce the chance of
burn-in and extend the life of the PDP. See “PICTURE MODE” on page 30.
„
Do not display static images or characters for long periods of time.
• Reduce CONTRAST and BRIGHT on the PICTURE menu (page 30) when viewing.
„
Do not view for long periods of time in the REGULAR mode (page 19).
Screen size is normally chosen to ensure that the picture is displayed on the entire screen. After
viewing in the REGULAR mode in which black bands may occur at the left and right of the screen,
it is recommended to change to the PANORAMIC mode to display the picture on the entire screen.
„
Do not view for long periods of time using the MULTI-PICTURE function (page 21).
If Burn-in has occurred
If burn-in occurs, try the REFRESH function (page 38). If burn-in is minimal it may gradually become
less noticeable.
Note: Once burn-in occurs it will never disappear completely.
