Check the voltage-is there short circuit
(短路量測方式)
1.Use the multimeter and switch to the diode stalls.
使用三用電表並切換到二極體檔進行量測
Multimeter OFF Multimeter switch to the diode stalls
2.Do not used any power in the camera.(Please reference to voltage measurement point)
過程中不要輸入任何電源(量測零件可參考電壓量測點)
Ex:
OK NG
Short-circuit approach,please reference repair flow chart measurement voltage,if the material are
short-circuit ,do not used the same material on the board.
短路處理方式，依照電壓更換相對應零件，過程中拆下零件就必須量測確認是否短路，才可以上件，避
免重覆零件燒毀。
Do not used power
請勿使用電源
