Important Service Safety Precautions

BEFORE SERVICING THE LCD MODULE, READ THE
SAFETY PRECAUTIONS IN THIS MANUAL.
WHEN REPLACEMENT PARTS ARE REQUIRED, BE
SURE TO USE REPLACEMENT PARTS SPECIFIED
BY THE MANUFACTURER.
Proper service and repair is important to the safe, reliable
operation of all HP equipment. The service procedures
recommended by HP and described in this service manual
are effective methods of performing service operations.
Some of these service operations require the use of tools
specifically designed for their purpose, and should be used
as recommended.
It is important to note that this manual contains various
Cautions and Notices that should be carefully read in order
to minimize the risk of personal injury to service personnel.
Improper service methods may damage the equipment. It is
also important to understand that these Cautions and
Notices are not exhaustive. HP could not possibly know,
evaluate, and advise the service trade of all conceivable
ways in which service might be done or of the possible
hazardous consequences of each way. Consequently, HP
has not undertaken any such broad evaluation. Service
technicians who use service procedures or tools that are not
recommended by HP must exercise caution and be sure that
neither their safety nor the safe operation of the equipment
will be jeopardized by the service method selected.

Warnings and Cautions

WARNING: Critical components having special
safety characteristics are identified with a
reference number in the parts list.
WARNING: Use of substitute replacement parts,
which do not have the same specified safety
characteristics, may create shock, fire, or other
hazards. Under no circumstances should the
original design be modified or altered without
written permission from HP. HP assumes no
liability, express or implied, arising out of any
unauthorized modification of design. The service
technician assumes all liability.
CAUTION: To ensure the continued reliability of this
product, use only the original manufacturer's
replacement parts, which are listed with their part
numbers in the "Replaceable Parts List" section of this
service manual.
WARNING: All ICs and many other
semiconductors are susceptible to electrostatic
discharges (ESDs). Careless handling during repair
can be life-threatening. When repairing, make sure
that you are connected with the same potential as
the mass of the set by a wristband with resistance.
Keep components and tools also at this same
potential.
WARNING:

WARNING: To prevent electrical shock, do not use
the polarized AC plug with an extension cord,
receptacle, or the outlet unless the blades can be
fully inserted to prevent blade exposure. To prevent
electrical shock, match the wide blade or plug to a
wide slot and fully insert.
WARNING: When replacement parts are required,
be sure to use replacement parts specified by the
manufacturer or have the same characteristics as
by the
the original part. Unauthorized substitutions may
result in fire, electric shock, or other hazards.
Never replace modules or other components while
the unit is turned on.
When making settings, use plastic rather than metal
tools. This will prevent any short circuits and the
danger of a circuit becoming unstable.
