What should I do if my Huawei phone falls and can t turn on?

Hello, there are several reasons why it won't turn on:

1. The boot line is abnormal: use an 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, 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 schematic 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 to check whether the waveform in the reset is correct.

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.

The phone was crushed by a child and could not be turned on. This is obviously a malfunction. It is necessary to find the after-sales maintenance department to do testing to determine the cause of the failure and the maintenance cost. Then decide whether to repair it or not.

Get it to a professional repair phone office.

Questions. The phone fell and now it can't be turned on.

Hello, if you can't turn on the phone after trying the above methods, it is recommended to send it to a Huawei mobile phone repair shop for repair in time to replace the internal and external screens, thank you.

There are many reasons why the phone cannot be turned on after it has been dropped, and you can analyze it simply.

First check if the phone screen is damaged, and secondly, consider whether the built-in battery is loose. Finally, consider the motherboard.

The mobile phone is most afraid of being bumped. After a fall, I will take a look at the screen to see if it is damaged. Because the screen is damaged, it will not be displayed, even if you press the power on and off button, there is no response, so you still go to the place where the phone is repaired for detection.

Secondly, the loose battery also needs to be disassembled and tested, and the all-in-one machine does not detect it by itself.

Finally, the motherboard problem refers to the desoldering of the internal components of the mobile phone after the fall, which affects the main components of the boot, which also needs to be tested by a professional repairer.

If you are not a professional repairer, then do not disassemble it yourself, so as not to expand the problem.

Huawei phones. Reasons why it can't be turned on after a fall:

Under normal circumstances, when pressing the boot button, the voltage of the trigger end of the boot button should change significantly, if there is no change, it is generally the poor contact of the boot button or the broken boot wire, the component is soldered and damaged. During maintenance, use an external power supply to supply power and observe the ammeter.

If the ammeter does not respond, it is generally a broken power line or a bad power button.

For most mobile phones, after the mobile phone is added with a battery or an external power supply, the power supply voltage is directly added to the power supply IC, if the power supply voltage is not added to the power supply IC, the mobile phone cannot be turned on.

If the power supply IC is not normal, the mobile phone should work normally, and the power supply circuit should output normal voltage to supply the load circuit. In the power supply circuit, the power supply IC is its core circuit, and the power supply mode is different for different varieties and models of mobile phones.

The system clock is one of the conditions for the normal operation of the CPU, and the system clock of the mobile phone generally adopts 13MHz, the 13MHz clock is abnormal, and the logic circuit.

If it doesn't work, it's impossible for the phone to turn on.

If the logic circuit is not normal, the logic circuit focuses on detecting the CPU to each memory.

These signals are important, but the key is to be able to look for these signals, as more and more mobile phone logic circuits are used in BGA packages.

, which makes it very difficult to find these signals.

The software is not normal caused by not booting, the mobile phone in the process of booting, if the software can not be passed, it will not be turned on, the software error is mainly due to the abnormal memory data, when the line is not obviously disconnected, you can first replace the normal chip, version or rewrite the software, some of the chip circuit will be damaged, and it can not be passed when rewritten.

There are many reasons why the phone does not turn on and the mobile phone does not turn on, such as the LCD screen.

Defects, short circuits in components (especially power amplifiers), etc., may cause the mobile phone not to turn on.

There could be a variety of reasons. After the mobile phone falls, the internally connected components may be damaged or loose, it is best to find a special repair of the mobile phone to test whether it is the first problem, it may be that the plug-in is loose, or it may be necessary to replace part of the hardware.

If you can't turn it on, if you're lucky, the battery pole may be loose, or the cable is loose, which is not very likely, because now mobile phones are all integrated design, unless it is particularly severe impact. Other reasons to rule out battery problems are motherboard problems.

The motherboard of Huawei's high-end mobile phone is a double-layer design, and the motherboard will be deformed, soldered, and dropped after the fall, and the chip desoldering and chip fragmentation are all possible, and they need to be disassembled for inspection and repair.

The reason why the Huawei phone doesn't turn on after a drop is because a certain component on the motherboard is soldered after the phone is dropped, which causes poor contact, so it can't be turned on.

One is that the battery connection cable is loose, and the other is that the connection to the CPU is broken, and in the end, it may be broken. It is recommended to go to the mobile phone store to find a maintenance master to test the specific situation, and please consult the maintenance master for the actual situation.

There are many reasons why the phone can't be turned on after a drop: it may be that the display screen is broken, or the internal hardware is broken, so it is recommended to go to Huawei after-sales service for testing.

1. First try to press and hold the home button and the power button at the same time, and try to use force restart to see if it can be turned on and restarted.

2. If you can't turn on normally after forced restart, charge your phone, sometimes it may be caused by no power.

3. If the mobile phone still can't be turned on after the above operation, it is recommended to connect the mobile phone to the computer and try to use the software to flash the phone.

4. If the mobile phone still fails to turn on after operating through the above methods, it may be caused by internal hardware damage to the mobile phone, and it is recommended to contact Apple after-sales maintenance to deal with the problem.

After the Huawei phone falls, it can't be turned on, the internal parts of the phone may be loose and fall off, or the motherboard may be faulty and damaged. It is recommended to go to the mobile phone store to find the maintenance master to test the specific situation, the actual situation please consult the maintenance master to understand, I hope to help you, I wish you a happy life!

Hello landlord!

This is an important question.

In reality, we need to use mobile phones.

If there is a problem with our phone.

We can try elimination.

We charge the phone.

See if your phone's charging indicator isn't flashing.

If your phone's indicator light is on.

We can take a look at fully charging the phone.

We turned it on several times to see how it went.

This charging indicator light is not on.

This indicates that the phone may be broken.

We can only repair mobile phones.

If the phone is still under warranty.

We can go to the local customer service center of Huawei mobile phones.

This ** is more affordable.

If the phone is out of warranty.

We can go to a nearby mobile phone repair shop.

Let's run a few more mobile phone stores**.

The above personal opinion.

Thank you**.

My Huawei phone Honor Ten also has the kind of problem you mentioned. But the difference is that sometimes he can't turn on the phone, but after three or four hours it will automatically turn on. I don't know if that's the case for you, but if that's the case, there's a 95% chance that the motherboard is damaged.

It is possible that the contact is not good, and you should take it to overhaul after getting it.
