There are occasions that intuition as to the origin of the problem of the iPhone fails us, in this post we will see the failures that occur in the Smartphone of the apple and have origin in the motherboard.
An iPhone like another Smartphone, consists of a motherboard with its different electronic components such as resistors, capacitors, diodes, transistors or integrated circuits among others, connected to each other.
Despite being expensive devices, they are also damaged like any other device that in its bowels carries a motherboard, also known as a motherboard, logic board or “motherboard”.
We’ve been researching iPhone motherboards for some time to find hardware solutions or new solutions to the electronic problems posed by damaged components.
Repairing a damage to the motherboard takes different steps from diagnosing the fault to finding the solution.
Luckily, the electronic schemes of iPhone are accessible and make it much easier for us to know which component is at a point on the board.
An endemic problem, and difficult to explain to iPhone users, is that although the failures are manifested in different components, see screen, microphone, speaker and even errors when you connect in iTunes, it seems that with changing the component should have been solved, but the result is that the piece works correctly and the origin of the problem is in the board.
Of the most difficult to explain are those related to the screen. Problems on iPhone devices
Below is a very short list of different motherboard issues that can affect your iPhone: Microphone Problem with the microphone in calls.
The model most prone to this failure is the iPhone 4 and although it seems a problem of the component, it can also happen that it is a failure of the audio integrated circuit.
When you talk on the phone, the other person doesn’t listen to you or listens to you choppy. At first glance it may seem like a microphone problem.
To determine if it is the microphone or motherboard try recording in the sound recorder application.
If the recording is successful the failure is of the motherboard.
However you should repair the motherboard of the iPhone 7 and iPhone 7 Plus when they have a problem that is common and widespread with the audio ic, the symptoms are:
The iPhone 7 takes time to start the operating system at startup, staying in Apple logo for several minutes. In the event that we decide to restore the phone, the restore process will be done successfully without launching iTunes any errors. But after restoring and at the time of starting the phone, it will continue to stay for several minutes in the logo of the apple. If we wait for the operating system to load, we can go to the sound recorder and if the record button is disabled it can indicate that the audio ic is also failing, it happens with the iOS 11 version of the system. Once the terminal has booted, if we make a call, the hands-free /speaker option will also be disabled (in iOS 11).iPhone microphone failure In iOS 12, we can go to the sound recorder and if we get the photo failure message, it is a symptom that the audio IC is failing.Do not charge
Charging problem. The most likely models are iPhone 5, 5S, 5C, 6, 6 plus, 6s, 6s plus, 7, 7 plus, 8 and 8 plus.
You’ve tried changing the cable, changing the charger, taking it to a repair shop, changing the charging connector and battery, and it’s still not charging.
In this case your iPhone has a problem on the motherboard, it would be the charging IC of the motherboard, also known as U2 or Tristar.
We do not know that the iPhone X, nor in any of the new models of 2018 this problem appears, so the repair of the motherboard in iPhone X would not proceed.Screen failures Blue screen
The apple comes out and turns blue after changing the screen.
The models in which this problem usually occurs are the iPhone 5S and the iPhone 6. Iphone with blue screen failure
You change the screen, turn on the mobile, the apple and blue screen come out.
It never finishes booting and entering the start menu.
This is once again a motherboard problem.
Other very common failures are: when a flashing gray line comes out at the top of the screen (it is a touch failure), the screen does not light up (backlight failure) or lines come out after changing the screen.
All these problems, we usually have a tendency to associate them with problems on the screen and the first option instinctively is to change it, seeing that that action does not solve the failure.
Tip: If your iPhone has any of these symptoms, before investing in a screen change, we recommend that you resort to a technical service specialized in micro-welding to verify that it is a failure of the logic board and not of the screen.
These failures require special attention since there can be several causes and solutions, so we have dedicated a post dedicated to each of them in depth: Touch You took it to repair it in case it was the screen, but they tried with one, with two, with three screens … and the touch didn’t work either.
In this case it is also a failure of the motherboard.
We have a post dedicated to what is known as iPhone touch disease or touch disease.Humidity
Moisture damage on iPhone. The most prone models are all, no one is free from having the bad luck of falling into the sea or the pool, spilling a glass of water, falling into the bathroom …
If you try to turn on or charge your mobile phone after getting wet, it is more than likely that you are damaging the electronic part of the phone.
Consult us before doing anything.
It would take us time to describe the different issues that your iPhone may present.
But you may have wifi failures, bluetooth, power integrated circuits, power + home button not working, welding, proximity sensor, audio, volume, error when restoring, etc.
If you notice that something is not working as it should on your phone, contact us and we will be happy to help you and be able to solve your iPhone. iPhone without service or coverage
This bug is common in the iPhone 5S, 5C, 6, 6 Plus, 6S, 6S Plus, 7 and 7 Plus, so a motherboard repair would be necessary.
When we are going to make a call, it is automatically cut off without letting us call and the message “Call error” appears on the screen.If in the “Phone” application we type *#06# and the IMEI of the phone does not appear.
The code* #06# is universal for all mobile phones and the IMEI must appear directly on the screen when typing the code
