Way for Deal iPhone 5S Camera Fault

Though iPhone 7 has become more and more popular, there still exist someone who prefers iPhone 5S. 

The next repaired iPhone 5S looks clean and beautiful, maybe its master treat it gently, but there seems happens some faults on its camera.

We have fixed many camera faults, most of them were caused by the corrosion and pseudo welding of the base. Anyway, let us check it.

According to our experience, we need to confirm the fault through the current and voltage. The following picture 1 is the basic structure of the rear camera circuit. Let's take a look at the iPhone 5S power supply part shown in the WUXINJI circuit diagram.

For the L29, L30, L28, FL43 components, it is easy to cause no power supply after water corrosion, the problem can be solved by short connection, U210 and U13, the two small glass IC also easily damaged cause no voltage output, it can be short connected as picture 2.

Be careful not to use hot air gun to remove the U210 and U13, because the Baseband chip is next to them! If you remove it with a hot air gun, the baseband chip will short.

First remove the black glue from the IC and heat with the HAKKO soldering iron.

Let's take a look at the circuit diagram of the front camera interface J1, as shown in picture3.

The voltage of 2.85V is sent to the interface through FL44, 1.8V passes through FL23 to the interface J1, FL44 and FL23 are easily corroded and damaged, resulting in camera function failure. Interface J1 water is easy to corrode too, patiently clean it and add solder paste or replace J1.

  

The video signal sent by main CPU is sent through FL13, FL15, FL12, FL14 to J1, inductor FL13, FL15, FL12, FL14 are easy to get corrosion and cause camera problems, short connection will solve the problem.

Fine, after you finish all the steps, open the camera APP, check it whether it back to normal.
