1. Safety Precautions

(1) When moving or laying down a LCD Set, at least two people must work together. Avoid any

impact towards the LCD Set.

(2) Do not leave a broken LCD 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.

(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) A LCD Set contains different kinds of connector cables. When connecting or disconnecting

cables, check the direction and position of the cable beforehand.

(6) 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.

(7) 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.
