1. Safety Precautions
I. Parts with the exception of MODULE
1. Safety Precautions
(1) When moving or laying down a PDP Set, at least two people must work together. Avoid
any impact towards the PDP Set.
(2) Do not leave a broken PDP Set on for a long time. To prevent any further damages, after
checking the condition of the broken Set, make sure to turn the power (AC) off.
(3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric
shock. When PDP is operating, high voltage and high current inside the Set can cause
electric shocks.
(4) When loosening screws, check the position and type of the screw. Sort out the screws and
store them separately for reassembling. Because screws holding PCBs are working as
electric circuit GROUNDING, make sure to check if any screw is missing when
assembling/reassembling. Do not leave any screws inside the set.
(5) If you open the BACK COVER, you will see a
Panel Gas Exhaust Tube (Picture. 1-1) inside
the bracket. If this part is damaged, the entire
PDP PANEL must be replaced. Therefore,
when working with the set, be careful not to
damage this part.
Picture 1-1. Panel Gas Exhaust Tube
(6) A PDP Set contains different kinds of
connector cables. When connecting or disconnecting cables, check the direction and
position of the cable beforehand.
(7) Connect/disconnect the connectors slowly with care especially FFC (film) cables and FPC
cables. Do not connect or disconnect connectors instantaneously with force, and handle
them carefully for reassembling.
(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, check their kind,
position, and direction.
