SAFETY INSTRUCTION
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
should enter the mouth, rinse the mouth thoroughly with water. 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
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. When attaching the LCD module to the LCD cover, position 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 module
because any impact can adversely affect the performance. Also use caution when
handling the polarized screen because it can easily be damaged.

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 module, use a wrist ground or anchor ground.
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.

10. When transporting the LCD module, do not use packing containing epoxy resin
(amine) or silicon resin (alcohol or oxim). The gas generated by these materials can
cause loss of polarity.

PANEL IDENTIFICATION
Panel Identification
If the several panels are alternatively used in the same model without amending the model
name, the identification marking will be shown at the last digit of the set serial number on the
specification label on the back cover.
In servicing, do not alter the panel because several setting and parts are different.

SAFETY INSTRUCTION
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. Always keep tools, components of the product, etc away from the children, These items
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
file://C:\Documents and Settings\Alexsandr\Local Settings\Temp\Rar$EXa0.545\32X... 07.05.2015
. 2 4
inflammability, voltage resistance, etc. therefore, use only replacement parts that have
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. NEVER remodel the product in any way. Remodeling can result in improper operation,
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.

Input resistance : 1M
Input capacitance : 200 pF
Frequency range : 15 Hz to 1 MHz and d.c. respectively
Note: Appropriate measures should be taken to obtain the correct value in case of non
sinusoidal waveforms.
The measuring instrument is calibrated by comparing the frequency factor of with the
solid line in figure F.2 of IEC 60990 at various frequencies. A calibration curve is
constructed showing the deviation of from the ideal curve as a function of frequency.
TOUCH CURRENT = /500 (peak value).
The potential at any point (TOUCH CURRENT) expressed as voltage and
does not exceed the following value:
The part or contact of a TERMINAL is not HAZARDOUS LIVE if:
a) The open-circuit voltage should not exceed 35 V (peak) a.c. or 60 V d.c. or, if a) is not
met.
b) The measurement of the TOUCH CURRENT shall be carried out in accordance with
IEC 60990, with the measuring network described in Annex D of this standard.
The TOUCH CURRENT expressed as voltages and , does not exceed the
following values:
- for a.c. : = 35 V (peak) and = 0.35 V (peak);
- for d.c. : = 1.0 V
Note: The limit values of = 0.35 V (peak) for a.c. and = 1.0 V for d.c. correspond to
the values 0.7 mA (peak) a.c. and 2.0 mA d.c.

Product Safety Notice
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.
