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.
Cautions
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.
