With the popularity of smart phones, there are more and more friends who use iphone mobile phones, and there are more and more problems we encounter in our daily life.
If there is a problem with the system, we can solve it by forcing a restart, if there is a problem with the hardware, then we need to send it to a professional repair shop for testing and repair.
1. System problems
If the mobile phone is not dropped or flooded, and there is a black screen failure under normal use, then it is generally caused by a system crash, in this case, we do not need to send it for repair, we only need to force restart the mobile phone to solve it, the specific operation method:
Quickly press the volume up button to let go, quickly press the volume down button to let go, and then keep holding the phone power button and don't put it until you see the phone appear on the boot screen and let go of the button, and the phone has completed the work of force restart.
2. Check the battery and charger
If the force restart doesn't work, then it may be that the phone battery is dead or there is a problem with the charger, we can try to change another charger or data cable to charge the phone and see if the problem persists.
It should be noted that if our iPhone has not been charged for a long time, then it may take about 30 minutes for the phone to react at the beginning of charging.
3. Hardware failure
Generally speaking, if our mobile phone has fallen or entered the water, then most of the black screen problems are caused by hardware problems, if the mobile phone is forced to restart according to the above methods, then it can be basically determined that it is a hardware problem, as an Apple mobile phone repair practitioner, basically every day there are customers who send the black screen and do not turn on the Apple mobile phone to repair, specifically, if the mobile phone hit** If the mobile phone is directly black and the screen does not respond, then it is generally caused by problems with the motherboard, common filter capacitor short circuit, hard disk damage, CPU virtual soldering, board layer disconnection and other problems.
If it is a screen problem, and the phone is caused by a fall, then we need to replace a screen assembly, if it is caused by water ingress, then we can repair the screen by pressing the row.
If it is a motherboard problem, we need to send the mobile phone to a professional third-party repair shop for repair, it should be noted that under normal circumstances, the mobile phone has a black screen failure, we do not need to replace the entire motherboard, it can be repaired directly, and the normal maintenance can be repaired in 1-2 hours.
