Iphone 5 – Dead – Need advice – iphone problem , and strang looking help anybody
Hello my friends,
so great to have an community Along with so many talented technicians.
So i thought you could to be helped me Along with my iphone 5 which fell to the floor (glass cracked) but worked until completely uncharged. Since then never started again.
While looking through the schematics and following traces I thought it would be a good way to read out Voltage at L1, because there should be USBHS ON/OFF TOLERANCE 5V/1.98V . But all I get there is 0,1 -0,2V which seems pretty unstable. As far as I see there is no want to read caps located nearby CPU cause if there is no Voltage at L1 there should not be correct Voltage so far in the circuit, which is the case, for example C71 has 0,1 -0,2V too. What I was curios about was that TP1 has stable 5V so docking connector seems to be OK.
Maybe someone had this symptoms or could give me an advice where I lose the voltage on circuit.
Also checked for shorts in caps located around CPU. All OK. A closer look through magnifier – All OK.
