Plasma TV panel
Check
The plasma TV 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.
Without signals and operations for 2 minutes, the level of the contrast decreases automatically
to prevent image retention.
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.
Sleep Feature
If the set is not switched off when the TV station stops transmitting, it will automatically go to standby mode after 30
minutes, This function will not operate when this TV is in AV mode.
