Hi
Board was liquide damaged. After cleaning by ultrasonic cleaner it was worked but one day later it stopped. When i checked voltage cant see PP5V_S3.
When i checked u7200 its too hot and replaced it 2 times but nothing changed its also hot. After that i was removed L7260,Q7260,Q6201,Q7220,L7220, and all resistors and capacitors around U7200 but same status
PPVIN_S5_5VS3 is 12.8 not problem. Do you have any suggestion ?
note: I checked PP5V_S3_REG and PP3V3_S5_REG not short a ground.
