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 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.
The display unit is fitted with a cooling fan to dissipate heat generated during normal
use. The whirring sound is caused by rotation of the fan and is not a malfunction.
