1. Safety Precautions 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.
