Symptoms Check
Some parts of the
screen do not
light up.
■ 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.
An afterimage
appears.
Do not allow a still picture to be displayed for an extended period, as this can cause a
permanent afterimage 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 afterimage 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.
Whirring sounds
can be heard
from the
display unit.
■ The TV includes a cooling fan to dissipate heat generated during normal use. The
rotating fan may cause a whirring sound which is normal.
