How to Repair iPhone 7/7P Audio Part Fault


If your cell phone gets the following faults like no voice can be heard when calling, no voice can be sent to the other side, no voice can be recorded, the phenomenon indicate that the audio components has some problems, in this article, we are going to repair damaged iPhone 7 and iPhone 7 Plus audio part.

Read iPhone 7 schematic diagram on WUXINJI Dongle , we learn that the audio part consists of audio decoding and ringing amplification. And the ring tone amplifier IC also controls vibrator function.

1. No voice can be heard when calling
When you have a cell on iPhone 7 or iPhone 7 Plus, you don't hear any voice. In this case, you need to firstly test the iPhone recording function.

If the recording function is normal, but the call is abnormal, then the problem is basically in the iPhone baseband part. In order to repair it, put your iPhone on the WL Aluminum Alloy Pad, and then you need to disassemble the iPhone by phone opening tools, remove the iPhone motherboard. Take off the iPhone baseband CPU, and then re-install it.

If the recording function is abnormal, then the problem is basically in the audio decoding part. In order to repair it, you can re-install audio decoding or replace the new one.

2. No voice sent to the other side

When you have a call on your iPhone 7 or iPhone 7 Plus, you can hear the voice from the other side, but no voice sent to him, he can't hear your voice no matter in normal call mode or hands-free call mode, the problem is the same.

In this case, you need to replace the iPhone Charger Port Flex Cable, reinstall or replace the iPhone audio decoding.

3. No voice when recording

If there is no voice when you use iPhone recording function, you need to repair by replacing the iPhone Switch Power Flex Cable.

4. No voice on receiver

In this case, you can replace the new receiver or receiver flex cable, re-install or welding audio decoding by QUICK 861DW hot air rework station.

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...

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 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...
