A customer said: his iPhone 6S dropped into water and cannot be turned on. It was fixed in Huaqiangbei, but the problem remains the same. Repair Process This iPhone 6S motherboard  is large area is water damaged and water has been cleaned. There are bumps on the upper board of CPU. After measuring, we find that the power supply of upper board is not short circuit. Plug the adjustable power supply  and the standby current is about 0.24A, as shown in picture 6-16. Picture 6-16 After measuring, we find that the diode data of PP_VCC_MAIN is small, only several tens. The capacitor near Wi-Fi chip  darkens badly. The location of darkened capacitor in bitmap is shown in picture 6-17 and its material object is shown in picture 6-18. Picture 6-17 Picture 6-18 Remove it and now the diode data of PP_VCC_MAIN is more than 100mA. As the water-damaged area is large, after observing carefully, we find that a capacitor at audio IC  darkens badly too. Its location...

IPhone 6 cannot be turned on after dropping into water. After plugging the adjustable DC power supply , the current display is 480mA. How to fix? step: Use multimeter  to measure PP_VCC_MAIN, finding that it is short circuit to ground. We can feel that power supply chip is hot when energizing it. Put a layer of white rosin at the circuits of PP_VCC_MAIN voltage. The short circuit place is where the rosin will first melt. After a while, we can see that the rosin on a capacitor near power supply chip melts first, as shown in picture 6-1. Remove the capacitor, the PP_VCC_MAIN is not short circuit. Picture 6-1 After plugging the adjustable power supply, iPhone still cannot be turned on. The current stops at 0.156A (156mA), as shown in picture 6-2. Picture 6-2 We continue to measure and find that the voltage of RESET_1V8_L is 1.1V. Its location in bitmap is shown in picture 6-3. The material object is shown in picture 6-4. Picture 6-3 Picture 6-4 We continue ...

More and more people use the iphone, so the iphone can be used in a variety of problems, such as the battery is not durable how to fix iphone battery trobble? Apple Stores will still replace your iphone battery . But that’s not an option for every consumer: some people can’t get to an Apple store; some folks need a cheaper, quicker option; and some folks (like us) just prefer to do their repairs at home We’ve been looking for a good, consistent DIY repair solution for folks who want to replace their own iphone battery for a while. But that battery glue makes it really challenging.so that makes the replacement part more expensive for owners We experimented with a lot of different options for how best to loosen that adhesive without compromising the battery. We tried heat—our go-to method for adhesive-logged devices. But getting heat to a iphone battery adhesive is hard: you either have to push heat through the battery (not safe), or pump enough heat through the keyboard ...

A custor said he took his iPhone6 go swimming,he iPhone 6 leaks electricity after dropping into water and the usage time is shortened badly. A full standby battery will run out next day.That's too bad, I can share some maintenance experience in this area, I hope it will help you. Repair Process Tear down iPhone and observe, finding that mainboard  is obviously watered. The water inflow label becomes red, as shown in picture 5-61. Picture 5-61 Remove the iphone Motherboard repair shielding cover   and find that motherboard components is eroded and goes mouldy. Use board-washing water to clean the eroded places and pry up the badly eroded and discoloured capacitors (picture 5-62).  Use preheater to dry the motherboard. Picture 5-62 After drying the motherboard, connect the adjustable DC power supply . The current shows 16mA. While before triggering on the normal iPhone 6 motherboard, four- number ammeter shows 0.000A. Showing 0.016mA suggests that it leaks...

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 ...
