iPhone Xs Max original touchscreen does not work
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.
After repair, the phone powers up but Original touchscreen not working. We put the original TS on another phone and it's fine.
The phone works well with a China display.
All the reading on J5800 is good using diode mode.
I have also replaced U5600 but still the same problem.
All related caps around U5600 is ok and not shorting.
U2900 reballing and on capacitor C2917 there is 1.1V
All power is present on the J5800 connector
Can anyone help please? Thanks
