Is there any way to solve the problem that iPhonexs suddenly has a black screen?

In the process of using Apple mobile phones, there may be problems with the hardware or software of the mobile phone, and the mobile phone will occasionally have a black screen. When there is a crash, how do we solve it? I'd like to introduce it to you today.

After you master these methods, you will be able to better deal with and use the phone when the screen appears black, and restore the phone to normal use as soon as possible.

Method. 1. Force the phone to restart.

When the Apple iPhone freezes and there is no response, at this time we can try to press and hold the "Power and Home Screen" button of the phone at the same time and keep it for more than 10 seconds. If the force restart is successful, you can see an Apple logo on the screen. After the reboot is successful, you can use the phone normally.

In addition, for some friends who like jailbreaking, you may often encounter the problem that your phone freezes and restarts automatically. In addition, I like to be a guinea pig, and when I update the iOS test firmware, there is a chance that there will be a black screen of crashes. These failures can be solved by trying this method first.

Method. 2. Charging.

Of course, sometimes it may be because the phone is out of battery, resulting in automatic shutdown, no matter how we operate, it can't turn on. When this happens, please plug your Apple iPhone into a power charger first. If the battery is automatically turned off because it is out of power, a battery icon will appear on the screen.

In addition, the battery of the iPhone needs to be charged to more than 5% before it can be turned on normally, if the battery is very low, please let it charge before turning it on. If there is still no response on the screen after connecting the charging power supply for the Apple mobile phone, then press the first method to operate, and press the "Power + Home Screen" button at the same time, and hold it for more than 10 seconds. If you can't solve it, you can test it with an external power supply.

If it can be turned on, it is a problem with the battery, and the battery can be replaced.

Method. 3. Hardware failure.

If the above two methods work, it may be a hardware failure of the Apple mobile phone, and it is recommended to send the mobile phone for repair to an Apple authorized after-sales service store for testing.

Method. 4. Exit recovery mode.

The iPhone system sometimes enters recovery mode, this we can use the method of exiting the recovery mode, and press the power button and the home button at the same time for 10 seconds.

When there is a black screen on our love machine, if the mobile phone is used during our warranty period, it is recommended that you take it to the Apple mobile phone after-sales service center for warranty. After all, the relevant technicians at the warranty point must be more professional, but the general warranty may take a long time. If your phone has passed the warranty time, it is recommended that you try the above treatment methods, of course, you must find the cause of the black screen of the mobile phone before solving it, and then you can quickly solve the problem of the black screen.

iphonexs is a full-screen mobile phone launched by apple, and the performance of the mobile phone is very good, but some friends have also encountered some problems in use, and some friends' iphonexs black screen cannot be turned on, what to do, to introduce it to you.

What to do if iPhoneXS black screen won't turn on.

1. Press the volume + button to release and then press the volume - button to release, and then press and hold the power button to force restart and see.

2. If the forced restart is invalid, you can use an external power supply to power the mobile phone, and then use the power meter to detect whether there is a change in the indication.

3. Use the external interface to power the mobile phone, see if the boot is back to normal, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

4. Test the schematic diagram of the hand-illuminated circuit on the test point of the peripheral circuit of the power supply IC to see if the test value is normal.

5. Problems with logic circuits: that is, faults in the circuit version of mobile phones, 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.

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 the mode in which the Apple system cannot be turned on if there is a problem, while entering the recovery mode can be recovered with iTunes. 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.

I'm an apple repair master, so I'll talk about it.

iPhone XS does not turn on is generally divided into several situations, 1. The software and system are incompatible and stuck.

2. Battery problems.

3.Problems with the motherboard chip.

First, you can press the volume up, then press the volume down, and then press and hold the power off button for 5 seconds. This kind of system problem can basically be solved in seconds, you can try it.

Second, the battery problem is good to replace the battery.

Third, the motherboard problem does not necessarily mean that the motherboard must be changed.

Motherboards are made up of hundreds or thousands of small chips, capacitors and resistors.

Including CPU, power chip, power supply chip, display chip, hard disk, baseband circuit.

Generally, it is only necessary to find out the faulty chip to replace, and there is no need to replace the entire motherboard at all.

Many masters in small places don't know how to repair the motherboard, and when you encounter a problem with the motherboard, you will be asked to replace it entirely.

It's very unnecessary, the chip is only a few hundred smaller.

It costs 23,000 to change the motherboard.

I've been doing motherboard repair work in Apple factory stores, so I know a lot about these.

Reasons for the black screen of the iPhone:

1. The boot line is abnormal: use the external power supply to supply power to the mobile phone, use the electricity 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 contact.

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

3. The IC of the mobile phone power supply is abnormal: the schematic diagram of the control circuit is outside the power supply IC.

The test is carried out on the test point of the perimeter circuit to see if the test value is normal. If the problem persists, it is recommended to bring your mobile phone to a regular Apple customer service center for inspection and repair.

Apple XS has a black screen, you can try the following methods to solve it:

1.Force Restart: Press and hold the volume up button and the side button at the same time, and press and hold until the Apple XS reboots and the Apple logo appears.

2.Check the hardware: Make sure the Apple XS has not been physically damaged, such as bending or getting water. In addition, check whether the phone camera cable is loose or not.

3.Check the charging situation: Use the original data cable and charger to charge the phone, and check whether the phone is responsive. If your phone is low on battery, it may not turn on.

4.Restart your phone: If the screen is still black after a force restart, you can try turning off your phone and then turning it on again.

5.Connect to your computer: Connect your phone to your computer and use iTunes to recover with a hand-lifted beam lifter. Note: This will erase all data from your phone, so be sure to back up important information before doing so.
