1.Safety 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 Sets 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 dama ge 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.
