■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.
(2) Kinds of the matters to be observed are classified and explained in the icons shown below.
• 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.
If this display is disregarded and equipment is handled
wrongly, this can be a cause of physical injury and a
fire, thus leading a person to death or serious injury.

This icon indicates the contents of “caution” that must be practiced, without fail.
This icon indicates a dangerous place where an electric shock is anticipated.
• 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.
• 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 BA9501 in the MAIN PWB) will give
rise to explosion if its polarity is wrongly treated.

Safety inspection after repairing
Explanation to the user
Explanation of use
• For the maintenance servicing, safety inspection is needed in accordance with the check list.
• Inspection should be carried out according to the check list shown below, in regard to
safety inspection before and after repairing, authentic repair, and explanation to the
user.
(Method of insulation check)
Mount a PDP module on the product to complete it. After the completion of aging and
others, pull out the power plug from the wall outlet, remove the cable, and turn on the
power switch. Use a 500V megger (Note 1) and confirm that the insulation resistance is
50M. or more between each terminal (except for the 3-core earth terminal) of the power
plug (Note 2) and the external exposed metallic parts (Note 3). If the insulation
resistance is found to be below the specified value, recover the faulty section and make
another insulation check again.
(Note 1) If a 500V megger is not available at that time, use a circuit tester or the like.
(Note 2) In the case of a 3-core terminal, the earth resistance shall be 1Ω or less
between the earth terminal and the earth side of each input terminal.
(Note 3) Head phone jack, speaker terminals, remote control terminals, each I/O
terminals, control terminals, screws, etc.

■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) For this product, the PDP modules and the PWBs are repaired by replacement in a unit.
Therefore, the units of the PDP modules and the PWBs must not be repaired or disassembled.
Otherwise, the validity of warranty will be lost.
(3) 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.
(4) When a PDP module 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 should be incorporated in the product and aging treatment should be carried
out for about two hours (all screen display).
(5) Sulfides will deteriorate the PDP module 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.
(6) When taking out a PDP module from the maintenance package box, do it slowly so that the
• 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 is made of glass. If
any shocks or vibration is applied, it may be broken and the scattered glass chips will
be a cause of injury.
• Do not put anything.
• Do not put anything on the product. Otherwise, this can be a cause of injury as a result
of falling down or dropping caused by imbalance.
• Transportation must be done by enough personnel.
• The product is heavy. In the case of transportation, unpacking, or packing, more than
two persons should do it (four persons for a product of 50-inch or larger) by supporting
the top and the bottom of the product.

panel surface does not get any shock or stress.
(7) If one touches the connector of the flexible cable exposed to the rear side of the PDP module,
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.
(8) The panel surface of the filter and the PDP module 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.
(9) When the panel surface of the PDP module is 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. The cloth for wiping off should be clean. Never use the same cloth
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.
(10) Refer to the “Instruction Manual” in regard to contamination in the filter and the cabinet.
(11) When transporting this product, use the packing materials specified in the list of parts. Once
