Samsung SDI Co. Ltd. A/S Manual Plasma Display Module
** 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 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. PDP module is sensitive to dust and
humidity. Therefore, assembling and
disassembling must be done in no dust
place.
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.
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.
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. To prevent the Logic circuit from being
damaged due to wrong working, do not
connect/disconnect signal cables during
circuit operations.
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.
