The plasma TV 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.
Do not allow a still picture to be displayed for an extended period, as this can
cause a permanent after-image to remain on the Plasma TV.
Examples of still pictures include logos, video games, computer images, teletext
and images displayed in 4:3 mode.
Note:
The permanent after-image on the Plasma TV resulting from fixed image use is
not an operating defect and as such is not covered by the Warranty.
This product is not designed to display fixed images for extended periods of
time.
