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
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.
PDP module is sensitive to dust and
humidity. Therefore, assembling and
disassembling must be done in no dust
place.
PDP module has a lot of electric
devices. Service engineer must wear
equipment(for example , earth ring) to
prevent electric shock and working
clothes to prevent electrostatic.
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.
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 for Service (Handling, prevention of a electrical shock,
measure against power outage, etc)
( 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
- 6 -
connect/disconnect signal cables during
circuit operations.
Do thoroughly adjustment of a voltage label
and voltage-insulation.
Before reinstalling the chassis and the
chassis assembly, be sure to use all
protective stuffs 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, Manufactor 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.
( Precaution when repairing ESD )
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
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.)
- 7 -
After removing ESD assembly, put on it with
aluminum stuff on the conductive surface to
prevent charging.
Do not use chemical stuff using Freon. It
generates positive electric that can damage
ESD.
Must use a soldering device for ground-tip
when soldering or de-soldering ESD.
Must use anti-static solder removal device.
Most removal device do not have antistatic
which can charge a enough positive electric
enough damaging ESD.
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.
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.
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)
