Health & Safety Code Section 25249.6 - Proposition 65

SAFETY PRECAUTIONS

NOTICE : Comply with all cautions and safety related notes

located on or inside the cabinet and on the chassis.

The following precautions should be observed :

1. When service is required, even though the PDP UNIT an
isolation transformer should be inserted between the power line
and the set in safety before any service is performed.

2. When replacing a chassis in the set, all the protective devices
must be put back in place, such as barriers, nonmetallic knobs,
adjustment and compartment covershields, isolation resistor­capacitor, etc.

3. When service is required, observe the original lead dress. Extra
precaution should be taken to assure correct lead dress in the
high voltage circuitry area.

4. Always use the manufacture's replacement components.
Especially critical components as indicated on the circuit
diagram should not be replaced by other manufacture's.
Furthermore where a short circuit has occurred, replace those
components that indicate evidence of overheating.

5. Before returning a serviced set to the customer, the service
technician must thoroughly test the unit to be certain that it is
completely safe to operate without danger of electrical shock,
and be sure that no protective device built into the set by the
manufacture has become defective, or inadvertently defeated
during servicing. Therefore, the following checks should be
performed for the continued protection of the customer and
servicetechnician.

6. Perform the following precautions against unwanted radiation
and rise in internal temperature.

• Always return the internal wiring to the original styling.

• Attach parts (Gascket, Ferrite Core, Ground, Rear Cover,
Shield Case etc.) surely after disassembly.

7. Perform the following precautions for the PDP panel.

• When the front case is removed, make sure nothing hits the
panel face, panel corner, and panel edge (so that the glass does
not break).

• Make sure that the panel vent does not break. (Check that the
cover is attached.)

• Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.

8. Pay attention to the following.

• Pay extreme caution when the front case and rear panel are
removed because this may cause a high risk of disturbance to
TVs and radios in the surrounding.

Insulation Resistance Check

With the AC plug removed from an AC power source, place a
jumper across the two plug prongs. Turn the AC power switch on.

( Case of PD6001, AC power is alwayas on. )

(Case of PX-60XR5A, AC power is always on.)
Using an insulation tester (DC 500V), connect one lead to the
jumpered AC plug and touch the other lead to each exposed metal
part (input/output terminals, screwheads, metal overlays, control
shafts, etc.), The resistance should be greater than 4 MΩ.

Leakage Current Hot Check

Plug the AC line cord directly into an AC power source (do not
use an isolation transformer for this check).
Turn the AC power switch on.
Using a "Leakage Current Tester", measure for current from all
exposed metal parts of the cabinet (input/output terminals,
screwheads, metal overlays, control shaft, etc.), particularly any
exposed metal part having a return path to the chassis, to a known
earth ground (water pipe, etc.). Any current measured must not
exceed 1.0 mA.

Safety cautions

The matters to be observed without fail are explained below. These matters are indispensable for the
prevention of an accident during the maintenance servicing, the "security of products" after the completion of
servicing work, and the "prevention of the repeated occurrence of similar fault."

(1) The degree of danger and material damage, caused as a result of wrong use by disregarding the contents

of the display" is distinguished and explained in the table below.

If this display is disregarded and equipment is handled

WARNING

CAUTION

(2) Kinds of the matters to be observed are classified and explained in the icons shown below.

This icon indicates a dangerous place where an electric shock is anticipated.

This icon indicates the contents of "caution" that must be borne in mind, without fail.

wrongly, this can be a cause of physical injury and a
fire, thus leading a person to death or serious injury.

If this display is disregarded and equipment is
handled wrongly, this may lead to personal injury or
material damage.

This icon indicates the contents of "caution" that must be practiced, without fail.

WARNING

• Observe the caution matter, without fail.

• In the place where a particular caution is needed during maintenance servicing, such a
caution note is displayed with a label or a stamp that is given to the cabinet, chassis,
PWB, etc. These caution notes and also the caution matters of given in
the instruction manuals, etc., must be observed, without fail.

• Be careful of an electric shock or a burn.

• The power block or the PDP module involves the sections where high voltage or high
temperature is prevalent. When equipment is energized, use working gloves in order to
prevent an electric shock or a burn. At the time of transportation, disassembly,
reassembly, and the replacement of parts, such a servicing job must be done after pulling
out the power plug.

• Modification of equipment is absolutely prohibited. Use the specified parts at all times.

• If any modification is performed, the validity of the manufacturer's warranty is lost at that
moment. The personnel who did this modification is responsible for the physical injury or
the like, if it should occur as a result of the modification. The parts used are given the
safety-based characteristics, such as non-flammability or sufficient withstand voltage. The
parts to be replaced shall be those which are specified in the list of replacement
parts.(Example: The lithium battery (circuit symbol BT9501 in the MAIN PWB) will give
rise to explosion if its polarity is wrongly treated.

WARNING

• The replaced parts and wiring must be arranged in the original conditions.

• For safety reasons, insulation materials like tubes and tapes may be used or some parts
may be mounted clear of the PWB. The internal wiring and the fastening with the
clampers for separation from high-heat and high-voltage parts shall be returned to their
original conditions, without fail.

CAUTION

• Observe the caution matter, without fail

The caution matters of given in the instruction manuals, etc., must be

•

observed, without fail.

• Do not give shocks and vibration.

The panel surface (display plane) of the filter and the PDP module (include the PDP

is made of glass. If any shocks or vibration is applied, it may be broken

CAUTION

Miscellaneous caution matters

(1) This product uses highly integrated semiconductor parts. Since these parts are fragile to

electrostatic charges, earth bands should be used for handling. The product should be handled
where measures have been taken against electrostatic charges.

(2) If this product is used for the fixed character display or the like as in the case of a character

display board, a phenomenon of burning (not warranted) will occur. Burning is a phenomenon
that the unevenness in the brightness is caused in the display. In such a case, the brightness in
the section where the integrated display time is longer becomes lower than the brightness in
another section where the integrated display time is shorter. This phenomenon is in proportion
to the integrated display time and the brightness. For this reason, to relieve this difficulty during
servicing, do not use any still picture, but use a display by motion pictures of a video or the like.
In addition, use "FULL" for the screen mode and avoid using any display by "NORMAL",
"TRUE", or MULTI SCREEN like side by side etc. If it is necessary to use only a still picture for
unavoidable reasons, use a burning relief function such as "PLE LOCK", "ORBITER",
"SCREEN WIPER", etc.

(3) When a PDP module (include the PDP Service ASSY) is operated after a long time of storage,

it may encounter a difficulty like a failure in displaying a screen or unstability according to the
condition of storage. In such a case, the PDP module (include the PDP Service ASSY) should
be incorporated in the product and aging treatment should be carried out for about two hours
(all screen display).

(4) Sulfides will deteriorate the PDP module (include the PDP Service ASSY) and this is a cause of

malfunction. Therefore, it is absolutely prohibited to put any vulcanized rubber or a material
containing sulfur in the vicinity of the PDP module (include the PDP Service ASSY).

(5) When taking out a PDP module (include the PDP Service ASSY) from the maintenance

5

package box, do it slowly so that the panel surface does not get any shock or stress.

If one touches the connector of the flexible cable exposed to the rear side of the PDP module

(6)

(include the PDP Service ASSY), there is danger of causing a poor contact. As such, it must be
handled with utmost care. In addition, the flexible cable is very weak in mechanical strength.
Therefore, this cable must not be touched during handling.

(7) The panel surface of the filter and the PDP module (include the PDP Service ASSY) is easy to

be hurt. These components should be handled very carefully not to press or rub them with a
hard thing. Never put them on a hard thing with the panel surface faced downwards.

When the panel surface of the filter and the PDP module (include the PDP Service ASSY) is

(8)

contaminated, gently wipe off the contaminant with a piece of soft dry cloth. Liquid-state
contamination can be removed by lightly pressing it, without rubbing it. If it is difficult to remove
the contamination, use a piece of cloth soaked with a neutral detergent

water.)

or a rubbing alcohol. The cloth for wiping off should be clean. Never use the same cloth

(Use it, diluting with

repeatedly. If a cleansing detergent or water drops should enter the module interior or be
attached to the module surface other than the display plane at the time of cleaning, this will give
rise to the destruction of the product when the product is energized.

(9) When transporting this product, use the packing materials specified in the list of parts. Once

used, such packing materials should not be used again.

(10) This product is composed of a variety of parts, such as those made of materials like glass,

metal, plastics, etc., and those like a lithium battery (circuit symbol of the MAIN ASSY: BT9501),
etc. Therefore, when abandoning this product, this should be done in accordance with the
relevant law of the nation or an autonomous body.

CAUTION: Risk of Explosion if Battery is replaced by an Incorrect Type. Dispose of Used
Batteries According to above the Instructions.

(11) You should use the following service tools when you replace ICs etc. since solder with free lead is

used in product.

The VSUS voltage remains for several minutes after the power to
the unit is turned off. These places must not be touched until
about 10 minutes after the power is turned off, or it is confirmed
with a tester that there is no residual VSUS voltage.

If the procedures described in “3.4 POWER ON/OFF FUNC-

-TION FOR THE LARGE-SIGNAL SYSTEM” are performed
before the power is turned off, the voltage will be discharged in
about 30 seconds.
