Check

Some parts of the screen

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

do not light up

elements or have luminous spots. This is not a malfunction.

 

 

Do not allow a still picture or any part of a still picture i.e. edges 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.

After-images appear

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.
