Then confirm the power supply source of PP3V3_G3H. PP3V3_G3H is outputted from U6990 via L6995. Locate U6990 with bitmap. Then locate the corresponding position of U6990 on the logic board.
Traces of damage can be found on chips around U6990. Confirm the working condition circuit of U6990 with drawing. Then locate L6995 with bitmap.
Run diode mode measurement of L6995. The measured value is normal.
