TV cabinet creaks When the TV is in use, there is a natural rise in temperature, causing the cabinet to

Plasma Display panel
Some parts of the screen do not
light up.
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.
After-images appear 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.
This product is not designed to display fixed images for extended periods of time.
Snapping sounds may be heard from
the display unit. This sound is produced when the cabinet expands or contracts due to variations in
temperature and is not a malfunction.
If your problem is not solved, turn your unit off and then on again.
Cautions:
Never attempt to repair a defective TV yourself.
