What to do if the iPhone screen is black, although the phone turns on and works

Why iPhone turns on, but the screen is black

Smartphone displays from Apple are characterized by high quality and contrast of the picture. But they are not immune to failure. Quite often fans of Apple gadgets are faced with spontaneous freezes and glitches, when there is a black screen on the iPhone. And such failures occur on all models, regardless of which version of iOS is installed. But you should not get upset prematurely. In most cases, the problem that caused the breakdown can be solved by your own efforts.

What to do if the iPhone screen is black, although the phone turns on and works

Causes of breakage

There are two types of problems that cause black screen: hardware and system.

iOS is one of the most advanced and reliable operating systems for mobile devices, but it is not immune to malfunctions. The black screen is often caused by software errors.

A failed firmware update of the smartphone can destroy the driver. The Apple mobile device must be reflashed very carefully, because they do not have a built-in Recovery menu.

Elementary hardware freezes can also cause a black screen. Sometimes it happens on a locked smartphone.

Mechanical damage should include:

  • Dropping from a height or a bump. The matrix cable may be disconnected from the connector.
  • Overheating of the smartphone leads to the failure of the chips.
  • Moisture ingress inside the case is another cause of failure.

When the battery fails to charge due to a broken charger or power connector, the screen will not turn on.

Restarting the device

You can reset the black screen on a working iPhone by restarting it. When the device freezes, restarting usually helps.

Press and hold the power and home buttons at the same time for about 20 seconds until the company logo appears. If the dark screen does not disappear after that, you should look for the problem elsewhere.

If your smartphone is on but the backlight is not lit, try the following

  • Go to the "Settings" menu and find the "Display" tab.
  • Set the brightness level to maximum. If the display does not respond to any manipulation of the dimmer, it is likely that the LEDs in the matrix backlight are out of order, or the problem lies in faulty firmware.
  • Perform a reboot of the device. After restarting, the problem should go away on its own.

But it is better to go to a service center for a complete diagnosis.

Reset Settings

Every year the requirements for multi-functionality of operating systems for mobile devices increase and iOS developers embed new modules in most regulatory programs. But they do not always work correctly with the current settings and applications. Often this has a negative impact on the functioning of the OS.

To minimize the chance of a black screen, you can do a full reset and restore the firmware.

To do this, open the menu "Settings", find the item "Basic" and then "Reset". After that, from the six options that open, select only two: "Reset all settings", "Erase content and settings".

In the first case, all personal data, including music, photos, videos, will be saved, only the smartphone will return to the factory settings.

To zero the iPhone, you need the second option. So click it and wait for the process to finish.

Checking the charger

The cause of the black iPhone screen may be a complete discharge of the battery. If you have been using your smartphone in the cold and later find out that the screen has gone out and the device does not turn on, do the following:

  • it is necessary to warm the device indoors or in your hands.
  • plug in the charger and wait 15 minutes.

If downloading does not start automatically, you should check the charger. When plugged in, the company logo should appear and the backlight should light up. If not, your charger is defective.

Conclusion

It is impossible to give advice to help in 100% cases. But a few recommendations will help minimize the risk of a dark screen.

  • Make sure that your iOS is not a beta version.
  • Do not leave your mobile device charging overnight.
  • Observe the simple rules for using your gadget during the cold season.
  • Do not accept the installation of applications embedded in system programs.

If the above methods don't work, try performing a factory reset. Then gradually change them and add apps from the App Store.

The option is not the best, but there is no other way to find out the cause of the black screen on the iPhone.
