Iphone 4s PP1V2 short - GSM-Forum

NikkyM · 05-14-2014, 17:27

Hello!
Iphone 4s does not start - only very hot-I've found ONLY line PP1V2_SOC short . (alleged water damage, but no corrosion, motherboard looks like new). Did I L23; L24; from C275 to C700 unsoldered (13 capacitor), all OK, only line still short (from PMIC to L23/L24 OK). Does anyone have idea, U52?; U5? or can come from BUCK2_FB line? regards

You cut XW2 and remove C307,and check if line from u5 to l23 is ok,then U52 is short or capacitors near u52

I have also shorted PP1V2_SOC and PP1V2_CPU and I am trying to find XW2 and XW3, I know that is placed near U52 , but I can not find where exactly is and what cut to separate U52 from U5
Anyone can tell me or take a photo where I should cut?
