820-3115 missing PP5V_S3

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.

U7200 can only get hot if one of the LDOs is overloaded. Only one connected to anything is VREG5, what is resistance to GND on that pin?

when i measure U7200 pin 17 ( PP5V_S5_LDO) its show 10K resistance but know good board its endless. then injected 5V this pin U5805 is hot and removed that ic but u7200 also hot. Maybe my u7200 was damaged
