Symptoms

Check

Some parts of the screen do

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

not light up

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:

After-images appear

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.

Whirring sounds can be heard

The display unit is fitted with a cooling fan to dissipate heat generated during normal use.

from the display unit.

The whirring sound is caused by rotation of the fan and is not a malfunction.
