A all-too-common vipprogrammer appointment went like this: A customer would bring in their iPhone 6S Plus and explain that they have been trying to charge their iPhone all night when iPhone 6S Plus dropping into water , Let’s get to the fixes,If this repair guide is useful, I hope you will recommend it to more iphone 6S Plus users. Repair Process Use a tester battery to offer power to motherboard  and test. USB current voltage meter shows that charging current jumps from 0.08~0mA. This phenomenon that there is no current when charging, but shows charging icon is called “battery drains” The charging chip  cannot output charging voltage normally, which causes the above problem. The frequent faulty points are USB chip damage or abnormal working condition of charging chip. Considering the inflow water in it, first we test the charging chip U2300. The charging management chip U2300 in bitmap is shown in picture 5-54. Picture 5-54 The most frequently damaged p...

More and more people use the iphone, inevitably, the iphone will encounter various problems in the use of the phone. The camera cannot take photos, so the customer changed camera 2.85V power supply chip  U3200. After turning it on, it immediately turns off. When receiving the iPhone and testing, it cannot be turned on. Repair Process After connecting adjustable power supply, there is no electricity leakage. Short connect it and turn it on to trigger the signal BUTTON_HOLD_HEY_CONN_L (picture 5-52). There is no current. Measure the power button signal and there is 1.7V voltage, which suggests that the standby circuits and trigger circuits have no problem. Connect adjustable power supply to energizing motherboard  and use USB cable  to connect iPhone and computer. Based on the iPhone design principle, after plugging USB cable, iPhone will turn on automatically. If this design works, then we know that the trigger circuit is damaged. After plugging USB cable for 2s, ...

Your iPhone will not turn on and you’re looking for help. It’s a problem that can be easy or difficult to fix, depending on the cause.In this article,A customer's IPhone6 after triggering it on, the turn on current is 70mA. This customer used iTunes to root it, but the root did not pass and iTunes reported error 4014. Repair Process Customer himself used air gun  to heat CPU. When connect computer to root, computer reports error 4014. In general, error 4014 suggests that CPU, Temporary Storage is more or less faulty or the power supply circuits are faulty. After removing the motherboard , we find that around the shield cover of motor drive chip U1400 there is some erosion mark, as shown in picture 5-41. Picture 5-41 Removing the shield cover , we can see that U1400 is eroded. Picture 5-42 shows erosion situation of the enlarged motor drive chip U1400. Picture 5-42 Clean the eroded places and replace U1400. Now iPhone can be turned on normally. The motor drive chip ...

It is a very muggy day, Vipprogrammer has been working hard, hoping to help more iphone users solve all kinds of incurable diseases。 A customer sent an iPhone 5S leaks electricity and the PCB is obviously hot. Step: Plug the adjustable power supply  and the standby current is about 50mA. After 1 min, we can feel that the baseband circuits and the front and rear sides are hot. Unplug and plug the adjustable power supply for several times, we can feel that USB Control chip  U2 gets hot faster than other parts. According to the repair experience, we remove USB management chip U2. The motherboard  without U2 is shown in picture 5-39. Picture 5-39 USB management chip U2 in bitmap is shown in picture 5-40. Picture 5-40 Replace U2 with a new USB management chip and assemble the iPhone. After testing, the electricity leakage disappears. Trouble is removed.

In our daily life, often encounter mobile phone charging fever, and battery power is very fast, so that we go out to bring a lot of inconvenience, as I share some of the maintenance experience in this area。 Steps： Plug the charger to charge for half an hour, finding that the iPhone is very hot and the temperature is nearly 70℃. Turn if off at once and tear it down to test. First, replace the Tail Plug Flex Cable , but the problem is still the same. Tear down the motherboard  and measure each relevant circuit. Measure the diode data to ground of each pin, such as charging tube Q2, USB Control chip  U2 and USB interface J7. We find that diode data to ground of pin 26th of USB interface J7 is abnormal which is larger than the normal one 20. The location of pin 26th of USB interface J7 in bitmap is shown in picture 5-36. Picture 5-36 After analyzing the circuit diagram , we know that pin 26th is connected to USB management chip U2. So replace U2 chip and turn on to t...

Iphone Mobile phone leakage is very dangerous, we must not be complacent, encountered such a problem to be in time to repair shop inspection and repair, here I share one points iphone SE leakage experience. A customer said his iPhone SE was water damaged and the backlight  was fixed. All the functions were normal, but it leaked 50mA current and cannot call out sometimes.

Tear down it and motherboard  leaks 50mA. Based on the description of customer, the problems happen on the signal part. The leakage is caused by components electricity leakage on main power supply PP_VCC_MAIN circuits. And PP_VCC_MAIN supply power to all the signal power amplifiers and baseband power, power amplifier power supply chips. Thus the damage of any of them could cause electricity leakage and...

Starting from front camera socket  J1111, we can see that the socket is split and the light-sense control tube Q1101 has been torn down. Replace the front camera socket and solder light-sense control tube Q1101. The material object of light-sense control tube Q1101 is shown in picture 4-81. Picture 4-8...

If you iphone 6 has no external sound,do not worry,vipprogrammer can help you share some of this experience。 External sound suddenly disappeared when the customer was watching film. He sent it to other maintenance shop to fix. Although the small audio  has been changed and iPhone has been rooted, the problem is still the same. Repair Process The external sound is produced by hand-free speaker. The problem is mainly caused by no handfree, which is easy to fix. The relevant components are large and small audio chips. Customer only sent its motherboard . We assemble it to tester assembly and turn it on to test. Except the ringtone handfree, other sound from the speaker and receiver as well as the recording is normal. The volume button works smoothly. If something wrong with the volume button , then the problem is very likely to be caused by the large audio chip. Based on the working principle, the Charge Jack  connects handfree speaker to power amplifier chips. First meas...
