Safety Instructions, Warnings, and Notes

EN 15SDI PDP 2.

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Handling Precautions

2.2 Safety Precautions

2.3 Notes

Notes:

• Only authorised persons should perform servicing of this
module.

• When using/handling this unit, pay special attention to the
PDP Module: it should not be enforced into any other way
then next rules, warnings, and/or cautions.

• "Warning" indicates a hazard that may lead to death or
injury if the warning is ignored and the product is handled
incorrectly.

• "Caution" indicates a hazard that can lead to injury or
damage to property if the caution is ignored and the
product is handled incorrectly.

2.1 Handling Precautions

• The PDP module use high voltage that is dangerous to
humans. Before operating the PDP, always check for dust
to prevent short circuits. Be careful touching the circuit
device when power is “on”.

• The PDP module is sensitive to dust and humidity.
Therefore, assembling and disassembling must be done in
no dust place.

• The PDP module has a lot of electric devices. The service
engineer must wear equipment (for example, earth ring) to
prevent electric shock and working clothes to prevent
electrostatic.

• The PDP module use a fine pitch connector which is only
working by exactly connecting with flat cable. The operator
must pay attention to a complete connection when
connector is reconnected after repairing.

• The capacitor’s remaining voltage in the PDP module’s
circuit board temporarily remains after power is “off”.
Operator must wait for discharging of remaining voltage
during at least 1 minute.

2.2 Safety Precautions

2.2.1 Safety Precautions

• Before replacing a board, discharge forcibly.

• The remaining electricity from board.

• When connecting FFC and TCPs to the module, recheck
that they are perfectly connected.

• To prevent electrical shock, be careful not to touch leads
during circuit operations.

• To prevent the Logic circuit from being damaged due to
wrong working, do not connect/disconnect signal cables
during circuit operations.

• Do thoroughly adjustment of a voltage label and voltage­insulation.

• Before reinstalling the chassis and the chassis assembly,
be sure to use all protective stuff including a nonmetal
controlling handle and the covering of partitioning type.

• Caution for design change: Do not install any additional
devices to the module, and do not change the electrical
circuit design.

• For example: Do not insert a subsidiary audio or video
connector. If you insert It, it cause danger on safety. And, if
you change the design or insert, manufacturer guarantee
will be not effect.

• If any parts of wire is overheats of damaged, replace it with
a new specified one immediately, and identify the cause of
the problem and remove the possible dangerous factors.

• Examine carefully the cable status if it is twisted or
damaged or displaced. Do not change the space between

parts and circuit board. Check the cord of AC power
preparing damage.

• Product Safety Mark: Some of electric or implement
material have special characteristics invisible that was
related on safety. In case of the parts are changed with new
one, even though the Voltage and Watt is higher than
before, the Safety and Protection function will be lost.

• The AC power always should be turned “off”, before next
repair.

• Check assembly condition of screw, parts and wire
arrangement after repairing. Check whether the material
around the parts get damaged.

2.2.2 ESD Precautions

There are parts, which are easily damaged by electrostatics
(for example Integrated Circuits, FETs, etc.) Electrostatic
damage rate of product will be reduced by the following
technics:

• Before handling semiconductor parts/assembly, must
remove positive electric by ground connection, or must
wear the antistatic wrist-belt and ring (it must be operated
after removing dust on it. It comes under precaution of
electric shock).

• After removing the assembly, lay it with the tracks on a
conductive surface to prevent charging.

• Do not use chemical stuff containing Freon. It generates
positive electric that can damage ESD sensitive devices.

• You must use a soldering device for ground-tip when
soldering or de-soldering these devices.

• You must use anti-static solder removal device. Most
removal devices do not have antistatic which can charge a
enough positive electric enough for damaging these
devices.

• Before removing the protective material from the lead of a
new device, bring the protective material into contact with
the chassis or assembly.

• When handing an unpacked device for replacement, do not
move around too much. Moving (legs on the carpet, for
example) generates enough electrostatic to damage the
device.

• Do not take a new device from the protective case until the
it is ready to be installed. Most devices have a lead, which
is easily short-circuited by conductive materials (such as
conductive foam and aluminium)

2.3 Notes

A glass plate is positioned before the plasma display. This
glass plate can be cleaned with a slightly humid cloth. If due to
circumstances there is some dirt between the glass plate and
the plasma display panel, it is recommended to do some
maintenance by a qualified service employee only.

2.3.1 Safe PDP Handling

• The work procedures shown with the “Note” indication are
important for ensuring the safety of the product and the
servicing work. Be sure to follow these instructions.

• Before starting the work, secure a sufficient working space.

• At all times, other than when adjusting and checking the
product, be sure to turn “off” the main POWER switch and
disconnect the power cable from the power source of the
display (jig or the display itself) during servicing.

• To prevent electric shock and breakage of PWBs, start the
servicing work at least 30 seconds after the main power
has been turned “off”. Especially when installing and
removing the Power Supply PWB and the SUS PWB in
which high voltages are applied, start servicing at least 2
minutes after the main power has been turned “off”.

Directions For Use

EN 16 SDI PDP3.

• While the main power is “on”, do not touch any parts or
circuits other than the ones specified. The high voltage
Power Supply block within the PDP module has a floating
ground. If any connection other than the one specified is
made between the measuring equipment and the high
voltage power supply block, it can result in electric shock or
activation of the leakage-detection circuit breaker.

• When installing the PDP module in, and removing it from
the packing carton, be sure to have at least two persons
perform the work while being careful to ensure that the
flexible printed-circuit cable of the PDP module does not
get caught by the packing carton.

• When the surface of the panel comes into contact with the
cushioning materials, be sure to confirm that there is no
foreign matter on top of the cushioning materials before the
surface of the panel comes into contact with the cushioning
materials. Failure to observe this precaution may result in,
the surface of the panel being scratched by foreign matter.

• When handling the circuit PWB, be sure to remove static
electricity from your body before handling the circuit PWB.

• Be sure to handle the circuit PWB by holding the large parts
as the heat sink or transformer. Failure to observe this

precaution may result in the occurrence of an abnormality
in the soldered areas.

• Do not stack the circuit PWB. Failure to observe this
precaution may result in problems resulting from scratches
on the parts, the deformation of parts, and short-circuits
due to residual electric charge.

• Routing of the wires and fixing them in position must be
done in accordance with the original routing and fixing
configuration when servicing is completed. All the wires are
routed far away from the areas that become hot (such as
the heat sink). These wires are fixed in position with the
wire clamps so that the wires do not move, thereby
ensuring that they are not damaged and their materials do
not deteriorate over long periods of time. Therefore, route
the cables and fix the cables to the original position and
states using the wire clamps.

• Perform a safety check when servicing is completed. Verify
that the peripherals of the serviced points have not
undergone any deterioration during servicing. Also verify
that the screws, parts and cables removed for servicing
purposes have all been returned to their proper locations in
accordance with the original
