iPhone 7 NO IMAGE
HI Everyone.. Hi @refectio Sir..
I have an iphone 7 for repair..
It is long story. Cliente sent me iphone with broken screen and in DFU MODE.
When i try to reset it with itunes i have error 6.
I reball NAND and phone reset perfectly.
After resetting there is no image on screen. I check with new screen but the problem is same.
I check all filter and found FL3901 damage. I dont have this filter ( im waiting new order)
so i jumped it and try to turn on the phone.
When i power on, i see the image (apple) only for few second and the problem come back.
I check all filter.. everything is perfect.
SO i check voltage on u3703 on all capacitor (c3711 to c3717)
(I do this without connect screen)
I have 6 volt only on c3717 , 16 and 15.
From c3714 to c3711 no voltage.
I putout the capacitor and check the voltage on the track but no voltage.
Unfortunally i dont have new ic for the moment, so i just reball it but the problem is same.
SO do u think the cause can be IC - u3703???
is this any ic on 6 or 6s series board who i can use on 7 board?
Thanks a lot guys for attention
