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 sign of 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 High Definition 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.

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.
