What if the screen of the mobile phone suddenly doesn't show anything?

1. What if the phone screen suddenly stops clicking?

If the phone can be turned on normally, the screen can't be lit normally, which may be caused by hardware failure.

Users can try to press and hold the power button to see if the phone can be forced to shut down and then restart.

If it can be turned on and off, it means that the buttons of the mobile phone are easy to use, but the screen is not.

Users are advised to bring their mobile phones, invoices and warranty cards to local brand customer service for testing.

When the mobile phone is sent to the customer service engineer, it will be tested to find out the cause of the failure and notify the user.

If the mobile phone is under warranty, it is a natural failure, and it is responsible for the warranty after sale.

If it is caused by insurance or human failure, it can only be repaired.

2. What if the mobile phone screen is not displayed?

Can the mobile phone be turned on/off normally? Can you answer the phone normally? Generally this situation has nothing to do with the software. Usually, the reason why the screen is not displayed is that there is something wrong with the hardware of the mobile phone, such as poor contact between the cable of the mobile phone and the mobile phone, or the cable of the mobile phone is broken after being used for a long time (a common problem of flip/slide phones). In this case, the screen of the mobile phone will not be displayed or displayed abnormally. Of course, if the mobile phone screen is broken, it may also cause this problem, but it is unlikely that the screen will be broken.

If the screen of the mobile phone is displayed but not lit when it is turned on, it is estimated that it is the backlight of the screen.

I suggest you go to the customer service center to check the specific cause of the failure. If the mobile phone is licensed, it will be repaired free of charge during the warranty period. After the warranty period or in a repair shop outside, it usually takes only about 40 yuan to change the line. Changing the screen depends on the material of the screen. If it is a color LCD screen, it usually costs several hundred yuan. In that case, you have to consider whether it is worth it.
