Replacement parts
When replacement parts are required, make sure that the
service technician uses replacement parts specified by the
manufacturer that have the same characteristics as the original
part. Unauthorized substitutions may result in fire, electric
shock, personal injury, or other hazards.
Safety check
After completing any service or repair to this device, ask the
service technician to perform routine safety checks to
determine that your TV is in correct operating condition.
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 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.
