A vertical line appears on the screen of the Huawei phone, which may be the inner screen of the phone is broken!

A vertical line appears on the screen of Huawei mobile phones, this may be due to the pressure of the mobile phone or the aging of the mobile phone screen, check it, whether this vertical line affects normal use, if it does not affect it, it will be used, if it affects the use, then the screen needs to be replaced.

If it doesn't affect the use, you can ignore it, and you're a screen failure as described.

It is possible that the screen is broken, or the contact is poor.

If a vertical line appears on the screen of Huawei mobile phones, it may be due to the following accessories:

1. LCD screen.

The mobile phone screen LCD screen is composed of an LCD screen panel, a light filter plate, and a backlight source. The liquid crystal liquid in the LCD panel is arranged on the LCD screen panel in the shape of "Tic-tac-toe", and the outside of the LCD screen is protected by the outer screen glass, but the LCD screen is very afraid of pressure from the front, such as accidentally sitting on a Huawei mobile phone, the LCD panel is damaged, and the liquid in the LCD screen is flowing out, which will cause the screen to appear, vertical straight lines or horizontal lines, if the amount of liquid outflow is relatively large, there will be a watermark effect.

2. Display the cables.

The display cable is a connection line between the LCD screen and the motherboard chipset inside the mobile phone, and the display cable is soldered, and poor contact will cause a straight line on the screen of the Apple mobile phone, and if the display cable is desoldered and disconnected, it will cause the mobile phone screen to be black. If the screen of a Huawei mobile phone is pressed, it will not cause the display cable to be soldered, only if the phone is dropped, it will cause the display cable to be soldered.

3. Display chip assembly.

The failure of the display chip component on the motherboard will not cause a straight line on the screen of the Huawei phone, but a black screen on the screen of the phone, so a straight line on the screen of the Huawei phone can rule out the problem of the motherboard display chip assembly.

4. There is a straight line conclusion on the screen of Huawei mobile phones.

Under normal circumstances, if the Huawei mobile phone has not been dismantled or repaired, there is a straight line on the mobile phone screen 80% of the possibility is the problem of the mobile phone screen LCD screen, because the mobile phone has not been disassembled and repaired, the Huawei mobile phone display cable is fixed very firmly when it is packaged, so there is only a 20% possibility that there will be a straight line on the mobile phone screen. But these two can not be judged by the naked eye by the appearance,You must disassemble the phone,Press and hold the cable to reinstall the cable first,If the straight line disappears on the screen, it means that it is a problem with the cable,Otherwise, it can be determined that it is a problem with the LCD screen。

Hello. A vertical line appears on the top of the screen of the Huawei phone, which means that the screen is malfunctioning. Don't figure it out on your own.

Don't do a factory reset. Personally, we recommend going to Huawei's official customer service center for screen detection. The official customer service has professional system software.

Indicates that the one on the screen where the line appears is damaged. In this case, there will be no repairs at the moment, and the screen can only be replaced or barely used. There is a bad spot on the screen, a dark spot is a leak, and a white spot is a blemish.

Only when there are too many or too large white spots, it is a quality problem, and the other two are generally man-made damage.

On your phone, find the service and turn on the tap screen detection, and the system will automatically detect the problem there in planning.

Reason: 1. The circuit of the mobile phone display screen is faulty, and the cable of the display screen is not in good contact.

2. The LCD screen of the mobile phone is broken, and the gap between the LCD screens will become larger after the LCD screen is squeezed, resulting in black lines.

3. The wiring of the source drive circuit of the mobile phone LCD is soldered, or the driver IC is damaged, or the IC peripheral circuit is damaged or soldered.

4. Trying to turn on or run the mobile phone after water enters the mobile phone will cause the screen color lines (red, blue, green) inside the mobile phone to burn out, resulting in a certain area that cannot be displayed, resulting in vertical lines.

5. The tail cable of the mobile phone display screen is broken or the battery that supplies power to the tail cable is broken, resulting in no power supply.

Answer: The sudden appearance of thin vertical lines on the mobile phone screen is usually caused by the failure of the mobile phone screen or cables, and in a few cases, the mobile phone software may also cause this phenomenon, so after the thin vertical line appears on the mobile phone screen, you can first restart the mobile phone; If the problem persists, open the phone Settings, pull down the phone screen, select System & Updates, tap Reset, select Factory Reset, and finally tap Reset Phone below to factory reset the phone. If it is a problem with the mobile phone screen, it is recommended to replace the original screen, because the original screen and the mobile phone have a higher fit.

If the landlord passes the above operations, the mobile phone screen is still a vertical line, then in this case. It should not have much to do with your mobile phone system, in this case, it is often related to the wiring and screen failure of the mobile phone, whether the external screen of the mobile phone is caused by external forces, etc. It is necessary to go to the after-sales service for inspection and maintenance.

1. If the LCD panel is damaged, the liquid in the LCD screen will flow out, which will lead to a vertical straight line or a horizontal straight line on the screen, and if the amount of liquid outflow is relatively large, there will be a watermark effect.

2. The display cable is a connecting wire between the LCD screen and the motherboard chipset inside the mobile phone, and the display cable is soldered, and the poor contact will cause a straight line on the screen, and if the display cable is de-soldered and disconnected, it will cause the mobile phone screen to be black. If the mobile phone screen is pressed, it will not cause the display cable to be soldered, and only the phone will be dropped.

3. The failure of the display chip component on the motherboard will not cause a straight line on the mobile phone screen, but a black screen on the mobile phone screen.
