2. Saf ety Precautions
(1) When moving or laying down a PDP Set, at least two people must be working.
Avoid any impact towards the PDP Set.
(2) Do not leave the broken PDP Set on for a long time. To prevent any further
damages, after check the broken Set's condition, make sure to turn the power
(AC) off.
(3) When opening the BACK COVER, turn off the power (AC) to prevent electric
shock. When a PDP is on, high voltage and high current exist inside the Set.
(4) When loosening screws, check the connecting position and type of the
screw. Sort out the screws and store them separately. Because screws holding
PCB are working as electric circuit GROUNDING, make sure to check if any
screw is missing when assembling.
(5) If you open the BACK COVER, you will see a Panel Gas Exhaust Tube.If this
part is damaged, entire PDP PANEL must be replaced. Therefore, when working,
be careful not to damage this part.
(6) A PDP Set contains different kind of connector cables. When connecting or
disconnecting connector cables, check the direction and position of the cable
beforehand.
(7) When disconnecting connectors, unplug the connectors slowly with care.
Especially when connecting/disconnecting FFC (film) cables or FPC cables, do
not unplug the connectors too much instantaneously or strongly, and always
handle the cables with care.
(8) Connectors are designed so that if the number of pins or the direction does
not match, connectors will not fit. When having problem in plugging the
connectors, make sure to check their kind, position, and direction.
