Maintenance

First, remove the mains plug from the socket outlet.
For regular care:
Gently wipe the surface of the display panel, cabinet, or pedestal by using a soft cloth to clean the dirt
or fingerprints.
For stubborn dirt:
Dampen a soft cloth with clean water or diluted neutral detergent (1 part detergent to 100 parts water).
Then wring the cloth and wipe the surface. Finally, wipe away all the moisture.
●
Do not use a hard cloth or rub the surface too hard. This may cause scratches on the surface.
●
Take care not to subject the TV's surfaces to water or detergent. A liquid inside the TV could lead to
product failure.
●
Take care not to subject the surfaces to insect repellent, solvent, thinner, or other volatile substances.
This may degrade surface quality or cause peeling of the paint.
●
Take care not to tap or scratch the surface with your fingernail or other hard objects.
●
Do not allow the cabinet and pedestal to make contact with a rubber or PVC substance for a long
time. This may degrade surface quality.
Wipe the mains plug with a dry cloth at regular intervals. Moisture and dust may lead to fire or electrical shock.

Pixel Statement
●
An image on a LCD or Plasma TV screen is created
by many small groups of dots known as pixels
(which is similar to the image in a newspaper). It
also naturally follows that higher panel resolutions
contain more pixels. To create a colour image, each
pixel consists of three tiny coloured dots (known
as sub-pixels), one each of red, green and blue.
Each one of these dots is precisely controlled by
the electronics of the TV to produce the picture.
Whilst Panasonic maintains the highest standards
in manufacturing technology and processes in the
construction of these panels, there are a number
of allowable pixel/subpixel failures that still allow
the panel to be defined as a good panel. It is not
possible to guarantee absolutely no pixel loss.
