Solution: iPhone 6 Receiver No Sound

We are going to fix an iPhone 6 today, the problem is that the receiver of the iPhone 6 has no sound. When the phone receive calls, we couldn't hear anything from the receiver. It just keep silence. How do we repair it step by step.


1. Test the iPhone 6. Use another cell phone to call this iPhone, the ringtone is normal, but when we answer this phone call, there is no sound.

2. Disassemble the iPhone 6. Use phone opening tool to disassemble the iPhone 6, take out the iPhonemotherboard.

3. Observe the iPhone motherboard. Observe this iPhone 6 closely with our eyes, the iPhone motherboard has been repaired, the motherboard has traces of water.

4. Remove the iPhone big audio IC. Put iPhone motherboard under the Stereo Zoom Microscope, and then use tweezers to remove the iPhone big audio IC. After remove the iPhone big audio IC, we found the bottom pin was corroded. 


5. Clean the corroded place. Use the BGA remove graver to clean the corroded part.

6. Solder the jump wire. Use QUICK 861DW hot air rework station to solder the jumper wire on it, and then apply some green UV oil to fix it. 


7. Install the iPhone big audio IC, assemble the iPhone and then test it, now the iPhone receiver works normally.

Solution: Why iPhone X Voltage Keeps Jumping

After getting the iPhone X motherboard to test, we observe the current value repeatedly jumps between 0mA and 50mA on DC power supply , and it is different from the normal booting current. Next, test whether the power supply of every circuit is normal. PP_VDD_MAIN is measured 4.2V; PP_VDD_BOOST measured is 4.2V. PP1V8-ALWAYS is 1.8V, all the values are normal. But when testing PP1V1_S2, PP0V8_SOC_FIXED_S1, PP1V8_S2 and other circuit voltage that output by power chip U2700 voltage are jumping constantly. According to previous experience, voltage jump is usually caused by a power supply circuit of U2700 output. Measured with digital multimeter , there is no short circuit was found for the dipole value of all power supply to ground. We repaired iPhone 7P before and know that if crystal oscillator is false welding can also cause voltage jumping, And if iPhone CPU  power supply is abnormal also can cause voltage jumping. Check the crystal oscillator we find no problem, then check th...

iPhone 6 Display Failure after Replacing LCD

The iPhone 6 display is black after replacing LCD. After checking, the diode data of display socket is normal and all power supply for iPhone display IC  output is normal. Testing by  DC power supply , we find the iPhone current is abnormal. When press the iPhone power button, the boot current is obviously large. The current reached 100mA when press the power button. After remove the display tube, the current still the same, which means there is a short circuit. Measure the voltage output of each circuit of power supply with Fluke 15B+ Digital Multimeter , then surprised to find that there are really short circuit places. LD010 is short circuit; we suspect that the filter capacitance on the circuit has been penetrated. After remove the iPhone power control IC , we found it is ground short circuit. Open the WUXINJI Dongle  to check the iPhone schematic circuit, we found that this circuit is the display card image transmission MIPI data bus power supply. CPU brea...

Iphone 6S Enters DFU Mode Cannot Start Fault Repair

The customer said that he did not know what the reason was. The mobile phone has been restarted indefinitely and can enter the DFU mode. However, when the flashing machine fails to enter the recovery mode from the DFU mode, and then the mobile phone is connected to the computer for 5-10 minutes, it automatically enters the recovery mode. After we received the 6S that could not be started, we disassembled the power with iphone engraving tool and turned on the power to 100mA. First of all, check if you can connect and read the DFU mode after connecting to the computer. Wireless DFU can not exit, we can only brush the machine to view the error. Refresh Aisi and iTunes respectively. If you stuck on the progress bar for a long time, it is very likely that the error is -1. If the progress bar does not enter, you can roughly determine the probability of a CPU failure. Now we need to see if there is a problem with the hard drive. First, use DC power supply for iphone repair, the hard disk o...
