2. PRECAUTIONS

** To prevent the risks of unit damage, electrical shock and radiation, take the
following safety, service, and ESD precautions.

2-1 Handling Precautions for Plasma Display

n PDP module use high voltage that is

dangerous to human. Before operating
PDP, always check the dust to prevent
circuit short. Be careful touching the
circuit device when power is on.

n PDP module is sensitive to dust and

humidity. Therefore, assembling and
disassembling must be done in no dust
place.

n PDP module has a lot of electric

devices. Service engineer must wear
equipment(for example , earth ring) to
prevent electric shock and working

n PDP module use a fine pitch connector

which is only working by exactly
connecting with flat cable. Operator
must pay attention to a complete
connection when connector is
reconnected after repairing.

n 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.

clothes to prevent electrostatic.

2-2 Safety Precautions for Service (Handling, prevention of a electrical shock, measure

against power outage, etc)

( Safety Precautions )

n Before replacing a board, discharge forcibly

The remaining electricity from board.

n When connecting FFC and TCPs to the

module, recheck that they are perfectly
connected.

n To prevent electrical shock, be careful not

to touch leads during circuit operations.

n To prevent the Logic circuit from being

damaged due to wrong working, do not
connect/disconnect signal cables during
circuit operations.

n Do thoroughly adjustment of a voltage label

and voltage-insulation.

n Before reinstalling the chassis and the

n 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.

n 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.

n 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
chassis assembly, be sure to use all
protective stuffs including a nonmetal
controlling handle and the covering of
partitioning type.

n Caution for design change : Do not install

any additional devices to the module, and
do not change the electrical circuit design.

n 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, Manufactor guarantee
will be not effect. .

Watt is higher than before, the Safety and

Protection function will be lost.

n The AC power always should be turned off,

before next repair..

n Check assembly condition of screw, parts

and wire arrangement after repairing.

Check whether the material around the

parts get damaged.

( Precaution when repairing ESD )

n There is ESD which is easily damaged by

electrostatics.(for example Integrated circuit,
FET ) Electrostatic damage rate of product
will be reduced by the following technics

n 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.)

n After removing ESD assembly, put on it with

aluminum stuff on the conductive surface to
prevent charging.

n Do not use chemical stuff using Freon. It

n Must use anti-static solder removal device.

Most removal device do not have antistatic

which can charge a enough positive electric

enough damaging ESD.

n Before removeing the protective material

from the lead of a new ESD, bring the

protective material into contact with the

chassis or assembly that the ESD is to be

installed on.

n When handing an unpacked ESD for

replacement, do not move around too much.

Moving (legs on the carpet, for example)

generates enough electrostatic to damage

the ESD.

generates positive electric that can damage
ESD.

n Must use a soldering device for ground-tip

when soldering or de-soldering ESD.

n Do not take a new ESD from the protective

case until the ESD is ready to be installed.

Most ESD have a lead, which is easily

short-circuited by conductive materials

(such as conductive foam and aluminum)

3-3 Main function of Each Assembly

■ X-main board : The X-main board generate a drive signal by switching the FET in synchronization with logic
main board timing and supplies the X electrode of the panel with the drive signal through the
connector.

1) Maintain voltage waveforms (including ERC)

2) Generate X rising ramp signal

3) Maintain Ve bias between Scan intervals

■.Y-main board : The Y-main board generate a drive signal by switching the FET in synchronization with the logic
Main Board timing and sequentially supplies the Y electrode of the panel with the drive signal
through the scan driver IC on the Y-buffer board. This board connected to the panel’s
Y terminal has the following main functions.

1) Maintain voltage waveforms (including ERC)

2) Generate Y-rising Falling Ramp

3) Maintain V scan bias

■ Logic main board : The logic main board generates and outputs the address drive output signal and the X ,Y

drive signal by processing the video signals. This Board buffers the address dirve output
