iPhone 6S phone can’t take photos for repair

Machine model: iPhone 6s

Fault symptom:water damage can’t be shoot after Camera.

Maintenance process:

After receiving a iPhone 6s,water damage from the customer for a while, I found that Camera on the back of the mobile phone could not be shoot. After I took it and replaced it with an Camera, I found that the fault remained. Therefore, the mainboard was removed for maintenance. Under the microscope, it was found that the rear Camera Camera 2.85V MOSFET had been burned down. At that time,shoot was forgotten, so the chip was taken down directly. The main Camera VCC_MAIN converted 2.85V to Camera.In the 6th generation, it was given to the former Rear Camera VCC, but on the 6th generation, this chip only gave the rear camera VCC.

After removing the chip, it was found that the main VCC pin bit had been burned. Because the chip is small and difficult to replace, it is not advisable to take short-circuit directly.unstable, taking pictures at night is not clear, so I intend to borrow 3V VCC directly. I heard that there is a 3V test point near the middle board screw on the motherboard, so I plan to test VCC from there, because recently, there are four test points.I’m not sure which one it is. After scraping off one, I tested it with multimeter and found that it was this proper 3v.
