Symptoms
Some parts of the screen do
not light up.
After-images appear
Plasma Display panel
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 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 Display.
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 Display 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.
