• 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 TV is fitted with a cooling fan to dissipate heat generated during normal
use. The rotating fan may cause a whirring sound but it is not a malfunction.
After initial setup, it can take up to a week to populate the full 8 days of listings.
Once fully populated, 8 days of program information should always be available.
You should begin to receive listings again within 24 hours.
You can correct them using Change Channel Display under Setup.
Listings begin to appear within 24 hours after a successful Setup.
