The reasons why iPhone8 suddenly won't turn on are as follows:

1. Software failure: Try to restart the phone, first press the volume plus button to release, then press the volume down button to release, and then press and hold the power button until the screen goes black.

The Apple logo appears.

2. If it still can't be solved, it is estimated that it is a hardware failure: generally the reason for not turning on is the motherboard chip or board layer line problem. It needs to be tested to determine, and each chip on the motherboard, including CPU, display chip, touch chip, power chip, battery and board line, is detected through the motherboard current instrument.

3. Check if one of them is blackened, short-circuited, or soldered. It is then repaired by chip transplantation technology.

iphone x

It is an iPhone series of smartphones designed, developed and sold by Apple. Published on September 13, 2017 by Apple CEO Tim Cook.

Released at the Steve Jobs Theater, it is a commemorative model for the 10th anniversary of Apple's iPhone. The iPhone X operating system uses iOS 11

It is powered by the Apple A11 Bionic processor and has 6 processing cores, which is a high-end model. It has a new design on the exterior and is equipped with an OLED screen with sharp colors.

And with the 3D facial recognition (Face ID) sensor, it is a classic product from Apple. The whole iPhone X looks like an almost entire screen, and Apple's official website in China describes the full screen design of the iPhone X this time. The iPhone X does away with the bottom Home button that Apple has been using for 10 years.

It is designed with a double-sided glass + metal middle frame, the material is OLED, and it is coated with an anti-oil stain and anti-fingerprint coating, and the interface at the bottom and the buttons on both sides are designed to be the same as the seventh generation of the iPhone series, and there is no change. How it works:

The phone screen is black, no matter how you press it, there is no response, just like the one below, it belongs to a kind of pure black.

The first method is to press and hold the volume button down + power off button + home button for about 10 seconds and wait for the phone to restart.

In fact, if it is a firmware problem, such as a system problem, you can perform a factory restore, first connect to the computer with a power cable, open iTunes, and press and hold the volume down key and the power button at the same time for 10 seconds, you can see that iTunes is connected to the display, and then click to restore.

If the above methods are not good, that is, the motherboard is broken, at this time you have to find a professional person to repair, under normal circumstances, many people are not professional enough, blind asking for the price, so to understand that it is broken, generally there is a problem in a yellow mark below, just need to change it, there is a power supply IC

Finally, the phone can be turned on normally, under normal circumstances, I use the restart function to turn on normally, I hope you can also use it normally.
