The phone screen suddenly didn t light up, and there was still a program

Maybe it's a bad contact.

The screen is broken or the backlight is broken.

Introduction: 1. The reasons why the mobile phone screen does not light up are as follows:

1. The phone is overheating: After opening too many programs, the CPU load of the mobile phone is too high, the mobile phone is hot, and the screen is not powered enough to cause a black screen, it is recommended to close other programs running in the background.

4. It is normal to put it next to your ear to answer the black screen of the mobile phone when you are on a call, if it is still in a black screen state when you leave your ear, it is suspected that the sensor is damaged and needs to be repaired.

5. Wiring failure or poor contact, screen damage, etc.: If the above reasons still cannot be removed, and the mobile phone is suspected of malfunctioning, it is recommended to go to the mobile phone after-sales point for inspection and repair.

We all naively thought that time could dilute everything, but we didn't expect that even if the eye-catching wound was scabbed, the scar of the past was a lifetime of traces on the body, and time could only make us learn to let go, but there was no way to erase the past experience, the scar remained, never disappeared, and time quietly took away, maybe it was the stupidity and stupidity at that time.

The reasons why the phone screen does not light up are as follows:

1. The phone is overheated: too many programs are opened in the background, the CPU load of the phone is too high, the phone becomes hot, and the insufficient power supply on the screen is easy to cause a black screen.

4. It is normal to put the phone next to the ear to answer the black screen when you are calling, if it is still in the black screen state when you leave the ear, you suspect that the sensor is damaged and you need to go to the mobile phone store for repair.

5. Mobile phone cable failure or poor contact, screen damage, etc.

If the above reasons still cannot be solved, it is recommended to go to a mobile phone repair shop for repair.

1. Although the current touch screen is very hard and wear-resistant, static electricity, an extremely unstable factor, can easily break through the capacitive screen. Although the surface of the capacitive screen will be added with a layer of antistatic treatment, it does not mean that it can withstand the instantaneous voltage brought by the static electricity of the human body. 2. The high temperature mobile phone screen is afraid of high temperatures, when the surface temperature of the screen reaches about 40 degrees, it may cause drift, and the capacitive screen will reduce the life of the capacitive screen if it is at this high temperature for a long time.

Therefore, in the scorching summer, try to avoid exposing the mobile phone to the outdoors when outdoors, and playing games for Android phones for a long time will also cause high temperature of the machine. If you're in the heat, the best thing to do is to let him cool. 3. Oil and sweat and other mobile phone screens are very afraid of conductive media such as oil and sweat, and their coverage on the screen will make the mobile phone screen unresponsive or screen drift, so if you find oil, sweat and other substances, you should wipe them dry as soon as possible.

4. The working principle of the voltage capacitive screen is that when the finger touches the capacitive screen, it will take away the point current on the screen, and the screen will evenly transmit the equal current from the four corners to fill the position of the paper press, and use this to do the positioning, so in the case of unstable transmission voltage, the effect of drift will appear, so try to avoid charging after the power is less than 20%, if it is lower than the best to charge immediately. And it's better to charge the mobile phone battery as you use it than to flush it when it's exhausted. 5. Put a small magnet on the screen in the magnetic field, and you can soon find that the capacitive screen has a temporary failure, which will cause permanent failure after a long time.

Therefore, try to avoid close contact between the phone and the speaker or other magnetic objects.

This is the phenomenon of sudden shutdown of low battery, and some crashes or some malfunctions, which will also cause screen failure.

If the power of the mobile phone is insufficient, you can speculate according to the charging situation of your mobile phone, and you can turn on the screen after charging for a few minutes; 4. If the above methods cannot be solved, there should be a problem with the hardware or firmware, and it should be sent to the maintenance office for repair immediately. Understand the TV network
