6. Please refer to the detailed list before replacing components that have special safety requirements Do not change the specs and type at will 2 Points for attention in servicing of LCD 2 1 Screens are different from one model to another and therefore not interchangeable Be sure to use the screen of the original model for replacement 2 2 The operation voltage of LCD screen is 700 825V Be sure to take proper measures in protecting yourself and the machine when testing the system in the course of normal operation or right after the power is switched off Please do not touch the circuit or the metal part of the module that is in operation mode Relevant operation is possible only one minute after the power is switched off 2 3 Do not use any adapter that is not identical with the TV set Otherwise it will cause fire or damage to the set 2 4 Never operate the set or do any installation work in bad environment such as wet bathroom laundry kitchen or nearby fire source heating equipment and devices or exposure to sunlight etc Otherwise bad effect will result 2 5 If any foreign substance such as water liquid metal slices or other matters happens to fall into the module be sure to cut the power off immediately and do not move anything on the module lest it should cause fire or electric shock due to contact with the high voltage or short circuit 2 6 Should there be smoke abnormal smell or sound from the module please shut the power off at
