Damaged Iphone 5, missing components black screen $ problem in cellphone ios/hardware , assistance please
hello everybody I have to repair an iphone 5 16GB and kindly ask your to be helped.
It had broken screen, very damaged on top so I tried to repair it Along with a new lcd but Along with no succes. It doesnt turn and constantly vibrates when I connect to itunes. It vibrates Along with no lcd too.
I am sure the new screen works becouse I tried on another iphone.
So I checked motherboard and I detected missing components.
According Along with the pcb layout, missing components are:
c88 – 50 pf
fl34 – fuse
c246 – 0,1uF
I shorted pads where fl34 was placed. I think the phone should work Along without missing capacitors.
Along with no lcd and iphone connected to itunes I measure tension on some pins:
LCD_PWR_EN_CONN = 0V
LCD_PANIC_L_CONN = 1,8V
I know that when iphone vibrates there is a hardware faulty. There are some test point to figure out what is broken?
