How to slove iPhone 6 Camera Not Working Issue

Welcome to our troubleshooting guide dedicated specifically to camera related issues concerning the iPhone 6.when you turn on camera on iPhone 6 to take photos, you found the iPhone rear camera not working, it can't take pictures.

The J2321 is the interface of rear camera. After checking the iPhone 6 schematic diagram on WUXINJI Dongle , we know that there are 4 sets of power supply circuit; they go through inductance L2329, L2330, L2318, FL2343 to the rear camera interface J2321, where the PP2V85_RCAM_AVDD_CONN is 2.8V power supply! It is provided by the small glass ID-- U2301, when turn on the iPhone camera, the CAM_EXT_LDO_EN signal that sent from the iPhone CPU controls 2.8V voltage that output by U2301, and then after the inductor FL2343, send to the interface J2321.

No matter U2301 fell into water or ground, it is easy to damage, and then causes no 2.8V voltage; the final result is that the iPhone can't take pictures. For the damaged power supply tube, we can remove it directly. And the for the water damaged iPhone, the L2329, L2330, L2318, FL2343 is easy to corrode and cause not to take pictures, you can short connect it with QUICK 861DW hot air rework station and jump wire.

Also, the iPhone flash IC--U1602 has several data signal is share with camera (AP_TO_RCAM_I2C_SCL, AP_BI_RCAM_I2C_SDA), so, the short circuit iPhone flash IC -- U1602 also can cause iPhone won't take pictures.

The repair process for the iPhone camera can't take pictures is as follows:

1.check the socket for corrosion, if yes, clean it and weld it

2.check if inductance L2329, L2330, L2318 and FL2343 are open circuit, if yes, short connect it.

3.check if C2303 has 2.8V when open the iPhone camera, if not, replace the new U2301, or you can remove it and short connect it.

4.check if C2323 has 1.8V, C2389 has 1.2V, C2390 has 1.8V, if both of them is normal, and interface also weld well, then try to replace iPhone camera flash control IC U1602. Moreover, this IC output the flash light control signal PP_STRB_DRIVER_TO_LED_COOL, PP?_STRB_DRIVER_TO_LED_WARM, after iPhone boot flex cable interface to flash IC LED. If the flash light not working properly, first you should check LED.

5.Use Fluke 15B+ Digital Multimeter to measure the voltage of PP_VCC_MAIN on capacitor C1686 to check if it is normal, and check if L1605 is open circuit. If both of them is normal, but the fault is still exists, then you need to replace the U1602 flash IC.

Slove iPhone X Won't Turn On

Image
Customer delivered a iPhone X and described the fault is not to boot after the phone drop accidentally. It reports error 56 when restore the iPhone X. How to repair this fault? Because iPhone X is the two board connected through the middle column, it is easy to drop the point. It may be that the solder points from NFC chip to the CPU part have fell off. Take apart the iPhone X by iPhone Screwdriver Repair Tools , take the upper board off the main board, when separate the main board we see a row of points have fell off. Picture 19-3-1 Look at the location map on WUXINJI dongle , it is surrounded by a ground wire, in fact, there are 6 useful points dropped. The ground wire does not need to be filled, the 6 useful points are added by professional phone welding tools. These are the signal wires of the NFC chip, so the iPhone X would report error 56. Picture 19-3-2 Then the tin of the middle column is repaired by iPhone X BGA reballing stencil , and the AP part is welded bac

So, you recently purchased ZXW Tools from our vipprog online store have no clue how to set it up?  Well, here is a quick guide detailing the installation process. Step 1 Unbox the ZXW tools dongle and plug it into your Windows PC.  ZXW tools does not support Mac at this time, so you’ll need a Windows compatible box. Step 2 Download the ZXW Tools software [direct link].  The ZXW tools website is in Chinese, but lucky for you, we’ve made it easy for you to download the latest version of their software directly from our website.  The zip file contains all of the files necessary to run ZXW Tools (trace) and Blackfish (schematics).  There is no installation process.  You just need to copy the files over to a directory on your desktop. Step 3 After you’ve copied all of the files over to a folder on  your desktop, then just run the ZXW tools executable.as shown in the picture. When your first run the software, the program will ask you if you want to activate the dong

IPhone 6P Front Camera and Distance Sensor Fault

Image
Received a iPhone 6 Plus, the customer said that the front camera can not be used, and the distance sensor has problem too. The two failures are concentrated on the front camera flex cable, which is likely to be caused by the damage of the wiring. First, we have to eliminate the possibility of the external parts fault, then consider the motherboard problem. Remove the screen assembly and replace it with a good one, we still can't turn on the front camera and use the distance sensor. Disassemble to measure the ground resistance of the front camera seat of J1111 by Fluke digital multimeter , it is found that several pins are infinitely large, and the related inductors are loose when touch with the pen. It seems that the small components are pseudo welded. 19-1- 1 Remove the motherboard and observe it under the Trinocular Stereo Microscope , we can see that the touch was repaired before. 19-1-2 The back of the sub touch chip U2402 is the front camera seat J1111, an
