thank you for replay i dont have power boot cable to check the dc voltage

That's not how repairs are done.
You need an original power supply and a voltampermeter type c like in the picture.
and the photo shows the area damaged type c by water. and everything needs to be restored there, including even the smallest resistor.
and after that the connected original power supply should switch from 5v to 15-20v
