Member: 1133 Status: Offline Thanks Meter: 38 | XS Max Touch screen problem with original display, works well with China display I have an Iphone XSM that has never been repaired before. The problem was caused by a shorted capacitor at the PP_VDD_Main line. After repair, the phone powers up but Original TS 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. There is no voltages on the following lines PP3V5_RACER PP5V25_TOUCH_VDDH PP10V0_RACER PP1V8_TOUCH_RACER_S2 All related caps around U5600 is ok and not shorting. Can anyone help please? Thanks |
