There are some game consoles or similar that output different video signals
from those regularly used. Distortion due to lack of synchronization may occur
when such equipment is connected. However, this is not a malfunction.
When AUTO is selected under Colour System of SET UP for Input Signals, the picture
may not be coloured or may be distorted due to lack of synchronization, depending on
the quality of the recorded signal. However, this is not a malfunction. On such an
occurrence, select the appropriate Colour System for the input signal in use.
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 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.
