yet another iPhone 6s with no rear camera of flashlight


hi all,
the title should be quite familiar... these iPhones not having rear camera and flash light
my case is a bit strange.
i have no shorts on the 1.2V, 1.8V and 2,8V lines, and actually the power is correctly delivered to the camera connector however, the camera doesn't work, neither does the flahlight.
My investigation :
when rear camera is activated, 1.2V is missing. when front camera is activated, 1.2V is well delivered to the rear camera so i don't know what can be the issue.
can it be the strobe driver U3300 ?

all filters are good. the diode was burned because the cap C1530 is partially shorted. i replaced it and didn't succeed. i replaced U1502 2 times qnd no success
one more thing to do is to change the coil but i don't think it will help

Have you check for data supplies ?

If you have a working 6s you can compare the cam connectors resistance with your faulty motherboard.

If you have all the voltages reaching the connector properly. Most probably some of the data line is missing.


Hope that helps.

thanks for your help, i can't check the data lines continuty as there is no filters on the iphone 6 rear camera anymore. not like iphone 6
the data lines go directly to the processor. i tried to push a bit on the processor to make contact but doesn't help
do you have an idea how i can test the data lines ?

I think you have miss voltages on the PP_VCC_MAIN you need to check this voltage on rear camera line if you don’t find it make a jumper from PP_VCC_MAIN to rear camera line

Guys I appreciate your help. Just to let you know. As mentioned in the initial post, all power lines are ok, 2.8v behind vcc_main 1,2 and 1,8
1.2v is only available when front cam is on but when rear cam is on, 1.2v is not there. The power line is ok, but the voltage is absent so I think this is a CPU issue or a flash driver
