SERVICE SAFETY PRECAUTIONS

•The caution items shown here describe major safety issues and should always be observed.

•The meanings of the various indications are as follows.

WARNING

CAUTION

Indicates a hypothetical situation in which service personnel and nearby third parties, or even

end users due to a product defect after the service operation is completed, could possibly be in

danger of injury or even death in the event of operational error.

Indicates a hypothetical situation in which service personnel and nearby third parties, or even

end users after the service operation is completed, could possibly be in danger of injury, or

where there could be physical damage in the event of operational error.

* Physical damage means major damage to a home, furnishings and other possessions.

REMODELING

•Always advise users to keep children away.

There is danger of injury to children from tools, disassembled products, etc.

•Always disconnect the power plug before starting work whenever power is not required.

Failure to disconnect the power plug before starting work can result in electrical shock.

•Depending on the model, use an insulation transformer or wear gloves when servicing with the

power on, and disconnect the power plug to avoid electrical shock when replacing parts.

In some cases, alternating current is also impressed in the chassis, so electrical shock is pos-

sible if the chassis is contacted with the power on.

•Always use the replacement parts specified for the particular model when making repairs.

The parts used in products have the necessary safety characteristics such as inflammability,

voltage resistance, etc.; therefore, use only replacement parts that have these same character-

istics.

Use only the specified parts when the *mark is included in a circuit diagram or parts list.

•Parts mounting and routing of the wiring should be the same as that used originally.

For safety purposes, insulating materials such as tubing or tape is sometimes used and printed

circuit boards are sometimes mounted floating.

Also make sure that wiring is routed and clamped to avoid parts that generate heat and which

use high voltage. Always follow the original scheme.

•After a repair has been completed, reassemble all disassembled parts, and route and recon-

nect the wiring, in accordance with the original scheme.

Do not allow internal wiring to be pinched by cabinets, panels, etc.

Any error in reassembly or wiring can result in electrical leakage, flame, etc., and may be

hazardous.

•After completing the work, disconnect the power plug from the outlet, remove the antenna, turn

on the power switch. Then, use a 500V insulation resistance meter to check the insulation

resistance of the antenna terminal, other metallic parts and between the prongs of the power

plug to make sure that the insulation resistance is 1M Ωor more.

The set will require inspection and repair if the insulation resistance is below this value.

•Never remodel the product in any way.

Remodeling can result in improper operation, malfunction, or electrical leakage and flame,

which may be hazardous

HANDLING THE LCD MODULE

Safety Precautions

In the event that the screen is damaged or the liquid crystal

(fluid) leaks, do not breathe in or drink this fluid. Also, never

touch this fluid.

Such actions could cause toxicity or skin irritation. If this fluid

should enter the mouth, rinse the mouth thoroughly with wa-

ter. If the fluid should contact the skin or clothing, wipe off

with alcohol, etc., and rinse thoroughly with water. If the fluid

should enter the eyes, immediately rinse the eyes thoroughly

with running water.

Precautions for Handling the LCD Module

The LCD module can easily be damaged during disassembly

or reassembly; therefore, always observe the following pre-

cautions when handling the module.

1. When attaching the LCD module to the LCD cover, posi-

tion it appropriately and fasten at the position where the

display can be viewed most conveniently.

2. Carefully align the holes at all four corners of the LCD

module with the corresponding holes in the LCD cover

and fasten with screws. Do not strongly push on the mod-

ule because any impact can adversely affect the perform-

ance. Also use caution when handling the polarized screen

because it can easily be damaged.

CAUTION The metal edges of the LCD module

are sharp, so use caution to avoid in-

jury.

3. If the panel surface becomes soiled, wipe with cotton or a

soft cloth. If this does not remove the soiling, breathe on

the surface and then wipe again.

If the panel surface is extremely soiled, use a CRT cleaner

as a cleaner.Wipe off the panel surface by drop the cleaner

on the cloth. Do not drop the cleaner on the panel. Pay

attention not to scratch the panel surface.

4. Leaving water or other fluids on the panel screen for an

extended period of time can result in discoloration or

stripes. Immediately remove any type of fluid from the

screen.

5. Glass is used in the panel, so do not drop or strike with

hard objects. Such actions can damage the panel.

6. CMOS-LSI circuitry is used in the LCD module, so avoid

damage due to static electricity. When handling the mod-

ule, use a wrist ground or anchor ground.

GENERAL ADJUSTMENTS

SPECIFIC INFORMATIONS

7. Do not expose the LCD module to direct sunlight or strong

ultraviolet rays for an extended period of time.

8. Do not store the LCD module below the temperature con-

ditions described in the specifications. Failure to do so

could result in freezing of the liquid crystal due to cold air

or loss of resilience or other damage.

9. Do not disassemble the LCD module. Such actions could

result in improper operation.

10. When transporting the LCD module, do not use packing

containing epoxy resin (amine) or silicon resin (alcohol or

oxime). The gas generated by these materials can cause

loss of polarity.
