iPhone XR phone suddenly black screen does not turn on, charging is hot, with this artifact perfect repair.

Reasons why the Apple phone can't turn on:

1. There is no electricity. If you use up all the battery power, the charge needs to be charged to 5% before it can be turned on normally. So in this case, please let the phone charge for a while before trying to turn it on.

2. Software malfunction. If you are sure that the current battery of your phone is sufficient, but it cannot be turned on normally, there may be a problem with the software system of your phone. At this time, we can try to press the home button + power button on the home screen of the mobile phone at the same time until the screen is lit up and there is a display.

3. System crash. If none of the above solutions work, and you see an iTunes connection screen on your iPhone's screen, it means that your phone has entered recovery mode at this time. When this happens, the only way to do this is to restore the system for your phone.

Connect your phone with the computer with a data cable, press and hold the home button and the power button at the same time for 10 seconds, then release the power button and continue to press and hold the home button for 5 seconds, if you see the connection to iTunes, it is a failure, and you have to start again. If the screen doesn't light up after these 2 steps, you will enter DFU recovery mode, and then you can use iTunes to restore your iPhone, or use a third-party flashing software to reflash your iPhone.

Several situations and solutions for the black screen of the Apple mobile phone and the solutions:

One situation where the iPhone itself is unstable, resulting in a black screen. This kind of black screen can be attributed to an unstable automatic shutdown, which is because the machine is of poor quality, resulting in shutdown for no reason. Because there is no big problem with the hardware, you can just press and hold the power button and wait for it to turn on.

The second scenario. DFU mode is a mode in which the Apple system cannot be turned on when there is a cleaning problem, and it can be restored with iTunes when it enters the chaotic Zhengshan Complex Mold. But the phone is fine, and it can't be turned on because it can't be turned on because it has entered DFU mode by mistake, but it's actually very easy to solve.

You only need to press and hold the power button and the home button at the same time and wait for the iPhone to react, generally for more than 10 seconds, if there is no response for tens of seconds, the following steps continue.

In the third case, you need to enter DFU mode, first of all, iTunes must be installed on the computer, and you can ** a new iOS system. Or restore files with a backup beforehand. Of course, during the recovery process, the computer can be connected to the Internet, and it can also be ****, but the wait is longer.

There are six possible reasons why iPhone X won't turn on with black screen.

1. The boot line is abnormal: use the external power supply to supply power to the mobile phone, use the electric meter to detect whether the indication has changed, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, and if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the peripheral circuit of the power supply IC according to the circuit principle diagram to see whether the test value is normal.

4. The system clock and reset of the mobile phone are abnormal: you can use the dual total oscilloscope to detect the CPU power supply of the mobile phone and check whether the waveform in the reset is correct.

5. Problems with logic circuits: that is, faults in mobile phone circuit boards, which can generally be solved by repair welding.

6. Software conflict: The installed software does not match the system of the mobile phone, which may also cause the mobile phone to fail to boot, you can connect the mobile phone to the computer to delete the program.
