What should I do when I encounter a phone that won't turn on?

Normally, the phone can't turn on, it may be caused by the battery, so if we can't turn on the phone, we should first check whether the battery is currently charged, whether the battery is placed in the correct position, and whether the battery's electrodes are clean and dry. If the battery is confirmed to be in good condition, we should confirm whether the power button of the mobile phone is in good contact, if the above phenomenon can not be solved at this time, then we should send the mobile phone to a professional repair station to let professional staff help overhaul it, and the user had better not disassemble the mobile phone without authorization.

Hello, if your phone can't be turned on at the moment, it is recommended that you try it as follows.

1) Try changing the battery to try it out.

2) If there is only one battery, it is recommended to connect with the computer to charge, check whether there is a charging display, you need to activate the battery for about 2 hours, although it may not be displayed when connected, but it doesn't matter, observe whether there is a charging prompt after 2 hours, if so, turn to normal charging.

3) If it is still not displayed, it is recommended to contact the Tianyu after-sales service center, and the address of the Tianyu national after-sales service center.

Because B920 is not a smart phone, so it is very likely that the battery and the machine contact problem is not turned on, first of all, make sure that you have not dropped the mobile phone before, the possibility of not turning on the machine and the system is very small, but it cannot be ruled out, you first remove the battery and reinstall it to try a few more times, and then it is very likely to be a problem with the system!

I don't understand, I haven't encountered such a situation as you, why don't you go to the after-sales service to take a look, is it still under warranty? I think this situation should belong to the mobile phone itself, don't worry, isn't there after-sales! It's been repaired, and tell me about it, thank you!

Solution:

1) Check whether there is a virus on your phone.

If the phone suddenly and frequently restarts, it is likely that it is a virus. You can use the mobile phone security guard to scan and disinfect the mobile phone first, and clean it up.

2) Uninstall some unnecessary software.

If there are too many mobile phone installers and too many software running at the same time, it is easy to fail to run and restart.

3) Software conflict issues.

If you think about whether you have installed or upgraded any software recently, it is often these software conflicts that cause the system to restart automatically, so you only need to uninstall the software that caused the conflict.

4) Factory reset.

If you can't be sure what software or plug-ins are causing your phone to restart frequently, you can choose to factory reset your phone and save the more important things on your phone before doing so.

5) There is a problem with the SIM card.

In addition to the internal software problems of the phone, the hardware problems of the mobile phone can also cause the phone to restart, and the SIM card error is a common hardware problem. Change a SIM card to the phone and see if there is a reboot to determine whether it is a SIM card problem.

6) Phone battery contact issues.

Poor contact of the mobile phone battery will also cause the mobile phone to automatically restart, and you can take it to the mobile phone repair office for consultation and help.

My phone is also Tianyu B899, and it has crashed a few times, but it is not often recommended to go to customer service to see if there is a problem with the motherboard

Hello, 1) Try to change the battery to try it out.

Most of the power is used too thoroughly, the basic voltage of the battery is not enough, try it with universal charging, if it doesn't work, change the battery and try it again, then take the repair to test it to see if the power supply is broken.
