I have an iPhone XS Max that has never been repaired before. The problem was caused by a shorted capacitor at the PP_2V63_Nand.[br]
[br]
[br]
After repair, the phone powers up but Original touchscreen not working. We put the original TS on another phone and it's fine.[br]
The phone works well with a China display.[br]
[br]
All the reading on J5800 is good using diode mode.[br]
I have also replaced U5600 but still the same problem. [br]
All related caps around U5600 is ok and not shorting.[br]
U2900 reballing and on capacitor C2917 there is 1.1V[br]
All power is present on the J5800 connector[br]
[br]
Can anyone help please? Thanks
