(2) Do not leave the broken LCD Set on for a long time. To prevent any further damages, after
check the broken Set’s condition, make sure to turn the power(AC) off.
(3) When opening the BACK COVER, turn off the power(AC) to prevent electric shock.
(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) A LCD Set contain different kind of connector cables.
When connecting or disconnecting connector cables, check the direction and position
of the cable beforehand.
(6) When disconnecting connectors, unplug the connectors slowly with care.
(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, make sure to check their kind, position,
and direction.
