1. Safety Precautions

I. Parts with the exception of MODULE

(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,

afterchecking 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.

(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.
