How to solve the black screen after the iphone6sp phone is turned on?

The main reasons for the black screen of the iPhone are as follows:

1. The internal hardware of the Apple mobile phone is damaged or the screen is broken.

2. Entered Apple's DFU mode by accident, that is, the recovery mode of Apple's mobile phone.

3. It may be caused by the failure of the Apple mobile phone system to start.

First, the iPhone itself is a refurbished machine or other machine with quality problems, and occasionally there will be an unstable black screen, but it is not a damaged screen.

The second, which entered Apple's DFU mode by chance, is Apple's recovery mode.

The third possibility is that the Apple system won't boot.

The fourth is that the hardware is damaged and the screen is broken. It needs to be sent to the Apple Repair Center on the 8th floor of Block B, East Third Ring Road Jianwai SOHO, Chaoyang District for maintenance.

Press and hold the power button for a few seconds, and then slide it to power off when the red slider appears on the screen. Sometimes your iPhone is frozen or unresponsive, and you can't shut it down by normal methods at this time, you can use Force Restart and Force Shutdown to get your iPhone back to work. Force shutdown:

At the same time, press and hold the power (power button and power on and off button) home button, and release the home button after the black screen appears, the white apple logo will appear within a few seconds after the home button is released, at this time, the power button should not be released, wait until the white apple logo disappears and the screen is turned off to complete the shutdown.

If the black screen still can't be solved by yourself, you have to go to the mobile phone store to find a professional to repair it.

Apple 6S Plus suddenly black screen, you can try the following solutions:

1. Press the home button and hold it for 6-8 seconds to exit any program that can get your iPhone stuck.

2. Try to press and hold the power and off button, if it can be restarted, this is the best.

3. If that doesn't work, try pressing the home and hibernation wake buttons at the same time, and hold them for about 10 seconds to force the shutdown.

4. If the above methods don't work, you can try to connect to the PC and use the [Restart] function in PP Assistant, iTools and other tools.

Apple 6splus black screen reason: It is generally because of system software, falling or water ingress, factory quality and other problems.

First of all, you need to try to force restart the boot, here's how:

Sleep and wake up button on the right side of the phone;

2. Press and hold the circular "Home" button at the bottom of the phone at the same time;

1. Replace the original screen to test whether it can be turned on.

2. If it can't be turned on, it means that the motherboard is faulty. Motherboards have a lot of chips, capacitors, and power lines.

To determine which component failure causes the black screen, it is necessary for professional maintenance personnel to do it, and the method is roughly as follows:

1. By detecting whether the current value of the motherboard is too large, if it is too large, it proves that one or some components on the motherboard are caused by short circuit.

2. Take the lavender rosin method to test which component of the motherboard is too high, and professionals can see it by visual inspection.

3. After determining the specific short-circuited components, replace the short-circuited components through value shifting and welding technology.

4. Press the power button again to boot the test.

If it is successful, the problem is solved, and if it is unsuccessful, there are still other short circuits, and the above steps have to be repeated.

This process requires a very patient and experienced chip repair technician to make a perfect repair the first time, otherwise it will have to be restarted.

iPhone black screen.

There are generally several scenarios.

1.The screen goes black and recovers by itself immediately.

2.After the screen goes black, you have to press the power on button, which can be normal.

Solution] If it is the first case, occasionally it is mostly a system conflict, it doesn't matter, continue to observe, it's okay to continue.

3.After the black screen, the phone reacts, but the screen does not light up. Same after restart.

Solution] It may be a screen problem (including cable or inner screen), or a chip problem that controls the screen display, which can be repaired, and the most expensive is to change the screen, and the cable or chip is generally a few hundred smaller.

4.After the black screen, it recovers on its own, but it is very frequent, more than 4 times a day.

Solution] You can try to flash the phone, if it can't be solved, it is a motherboard problem, and you need to disassemble and repair the motherboard. If it is flooded or flashed, do not flash the machine, and go directly to repair the motherboard.

5.After the black screen, there is no response at all, and individual charging will heat up.

Solution] Battery or motherboard problems. Finally, it should be emphasized that the motherboard is composed of hundreds or thousands of small chips, capacitors and resistors, including CPU, power supply chip, power supply chip, display chip, hard disk, and baseband.

The circuit generally only needs to find out the fault of the chip replacement, there is no need to replace the entire motherboard, many small places do not know how to repair the motherboard, encounter the motherboard problems are to make you the whole replacement is very unnecessary, the chip is only a few hundred smaller to change the motherboard to 23 thousand.

Several situations and solutions for the black screen of the Apple mobile phone and the solutions:

One situation where the iPhone itself is unstable, resulting in a black screen. This kind of black screen can be attributed to an unstable automatic shutdown, which is because the machine is of poor quality, resulting in shutdown for no reason. Because there is no big problem with the hardware, you can just press and hold the power button and wait for it to turn on.

The second scenario. DFU mode is the mode in which the Apple system cannot be turned on if there is a problem, while entering the recovery mode can be recovered with iTunes. But it's no problem to clear the phone, and if you accidentally enter the DFU mode, you can't turn it on, and you think it's a phone failure, but it's actually very easy to solve.

You only need to press and hold the power button and the home button at the same time and wait for the iPhone to react, generally 10 seconds, if it is tens of seconds and there is no reaction, the following steps continue.

In the third case, you need to enter DFU mode, first of all, iTunes should be installed on the computer, and you can ** a new iOS system. Or restore files with a backup beforehand. Of course, during the recovery process, the computer can be connected to the Internet, and it can also be ****, but the wait is longer.
