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 elec-
tric circuit grounding, make sure to check if any screw is missing when assembling / reas-
sembling. 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.
