ok for me the problem is solved by changing one resistor.
I cant find schema for this model to show the place of this resistor but this is the solution i find.
good luck for all

sorry brother the first solution I show you work good for me and this is the first J150 i make.
but this is how i discover my problem:
first I am suspecting battery so for confirming this I powered my phone with UFC cabe but same problem I increase progressively the resistor value
3.3k same pbm
5.1k same pbm
7.5k and 10k phone powered on sucesfully
I spoke with a friend for me who know in repairing phone and he told me that there is one resistor who doesn't working correctly he change it and all is fine.
good luck
