i Have an iphone 5SE Along with a little water damage, just on the connectors lcd etc, i clean it and made some test,microphone etc, all was ok, i just shut down the phone to change the back camera.
i started the phone Along with the new camera, and the iphone show me logo and shut down etc etc.
i took a new batery, and the problem was the same so i checked the board and discover that the line PP_CPU_1.0V is shorted, so can it be the U2000?
i checked PP_VCC_MAIN and all is ok to C2120,C2121 and C2122 are ok not shorted.
