Power source
Operate your TV only from the type of power source
indicated on the marking label. If you are not sure of the
type of power supplied to your home, consult an
electrician or your local power company.
Servicing
These servicing instructions are for use by qualified
service personnel only. To reduce the risk of electric
shock, do not perform any servicing other than that
contained in the operating instructions unless you are
qualified to do so.
Caution
Damage requiring service
Unplug this TV from the power outlet and refer
servicing to qualified service personnel under the
following conditions:
• When the power supply cord or plug is damaged or
frayed.
• If liquid has been spilled or objects have fallen into
your TV.
• If your TV has been exposed to rain or water.
• If your TV does not operate normally by following the
operating instructions. Adjust only those controls that
are covered by the operating instructions because
incorrect adjustment of other controls may result in
damage and will often require extensive work by a
qualified technician to restore your TV to its normal
operation.
• If your TV has been dropped or damaged in any way.
• When your TV exhibits a distinct change in
performance.
Outdoor antenna grounding
If an outside antenna or cable system is connected to
your TV, make sure that the antenna or cable system is
grounded to provide some protection against voltage
surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA No. 70, provides
information with respect to correct grounding of the
mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding
conductors, location of the antenna-discharge unit,
connection to grounding electrodes, and requirements
for the grounding electrode.
Note to CATV system installer
Article 820 of the National Electrical Code, ANSI/NFPA
No. 40 provides guidance for correct grounding.
Specifically, it states that the cable ground must be
connected to the grounding system of the building as
close to the point of cable entry as practical.
Condensation
Moisture will form on the TV if the TV is brought from
cool surroundings into a warm room or if the
temperature of the room rises suddenly. When this
happens, the TV's performance may be impaired. To
prevent this, let the TV stand in its new surroundings for
about an hour before switching it on, or make sure that
the room temperature rises gradually.
Condensation may also form during the summer if the
TV is exposed to the breeze from an air conditioner. In
such cases, change the location of the TV.
Mobile telephone warning
To avoid interference with your TV picture and sound,
operating problems, or even damage, keep your
cordless and cellular telephones away from the TV.
End of life directives
Your TV may contain materials that are regulated for
environmental reasons. Your TV also contains materials
that can be recycled and reused. To help protect the
environment, contact your local authorities for
information about disposal or recycling and about
finding a recycler in your area before you dispose of
your TV.
Non-active pixels
The LCD panel contains almost 3 million thin film
transistors, which provide exceptionally sharp video
quality. Occasionally, a few non-active pixels may
appear on the screen as a fixed blue, green, or red point.
These non-active pixels do not adversely affect the
performance of your TV, and are not considered defects.
