Handling the LCD Module
Safety Precaution
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
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
CAUTION: The metal edges of the LCD module are sharp, handle it with
care.
The LCD module can easily be damaged during disassembly or reassembly; therefore,
always observe the following precautions when handling the module.
1.
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 module
because any impact can adversely affect the performance. Also use caution when
handling the polarized screen because it can easily be damaged.

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 solied, 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

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 conditions 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.

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "SAFETY
PRECAUTION" AND "PRODUCT SAFETY NOTICE" INSTRUCTIONS BELOW.
Safety Precaution
WARNING: SERVICING SHOULD NOT BE ATTEMPTED BY ANYONE
UNFAMILIAR WITH THE NECESSARY PRECAUTIONS ON THIS RECEIVER.
THE FOLLOWING ARE THE NECESSARY PRECAUTIONS TO BE OBSERVED
BEFORE SERVICING THIS CHASSIS.
1. An isolation transformer should be connected in the power line between the receiver
and the AC line before any service is performed on the receiver.
2. Always disconnect the power plug before any disassembling of the product. It may
result in electrical shock.
3. When replacing a chassis in the cabinet, always be certain that all the protective
devices are put back in place, such as nonmetallic control knobs, insulating covers,
shields, isolation resistor-capacitor network, etc.
4.
may cause injury to children.
5. Depending on the model, use an isolation transformer or wear suitable 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 possible if the chassis is contacted with the power on.
6. Always use the replacement parts specified for the particular model when making
repairs. The parts used in products require special safety characteristics such as
inflammability, voltage resistance, etc. therefore, use only replacement parts that have
NEVER remodel the product in any way. Remodeling can result in improper operation,

these same characteristics. Use only the specified parts when the mark is indicated in the circuit diagram or parts list.
7. Parts mounting and routing dressing of wirings should be the same as that used
originally. For safety purposes, insulating materials such as isolation tube or tape are
sometimes used and printed circuit boards are sometimes mounted floating. Also make
sure that wirings is routed and clamped to avoid parts that generate heat and which use
high voltage. Always follow the manufactured wiring routes / dressings.
8. Always ensure that all internal wirings are in accordance before re-assembling the
external casing after a repairing completed. 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.
9.
malfunction, or electrical leakage and flame, which may be hazardous.
10. Touch current check. (After completing the work, measure touch current to prevent an
electric shock.)
Plug the AC cord directly into the AC outlet. Do NOT use an isolation transformer
for this check.
Connect a measuring network for touch currents between each exposed metallic part
on the set and a good earth ground such as a water pipe.

Many electrical and mechanical parts in this chassis have special safety-related
characteristics. These characteristics are often passed unnoticed by a visual inspection and
the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement parts which have these
special safety characteristics are identified in this manual and its supplements; electrical
components having such features are identified by the international hazard symbols on the
schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The
use of substitute replacement parts which do not have the same safety characteristics as
specified in the parts list may create electrical shock, fire, or other hazards.
