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.
