Check

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 sign of 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 Wide Plasma Display.
Examples of still pictures include logos, video games, computer images,
teletext and images displayed in 4:3 mode.
