Black screen iPhone with mechanical damage? Let’s take a look inside.

A brief overview of the inside of your iPhone will help you understand why your screen is black. There are two hardware that we’ll talk about: the display of your iPhone and the logic board.

Logic board. these are the brains of your iPhone, and every part of it connects to it. The display shows the images that you see, and it is the logic board that tells you what to display.

The entire display of your iPhone is removable, but it is much more complicated than you think! Under the display there are 4 main components:

LCD screen displaying the images that you see on your iPhone;

digitizer, which is part of the display that processes touch. It digitizes your finger, which means that it turns the touch of a finger into a digital language that your iPhone can understand;

Each component of your iPhone display has a separate connector that connects to the logic board. This is why you can slide your finger across the screen even though the screen is black. The digitizer works, but the LCD does not work.

Basically, the screen of your iPhone has turned black because the cable that connects the LCD to the logic board is disconnected. This cable is called the display data connector. When the display data connector is displaced from the logic board, your screen becomes inoperative.

There are other options for the cause of the iPhone’s black screen, for example, when the LCD itself is already damaged and then it does not matter if the display is connected to the logic board or not. it is broken and need a screen (display) replacement iPhone

Mechanical damage. a reason to contact the service

As we already said, there are two main reasons why your screen goes dark. The first is if the cable that connects the LCD display to the logic board disconnects (moves away) when it falls, the second. the display itself is broken. Only experienced service technicians can determine the exact cause. In the service center "iMobi" will conduct free diagnostics of your device and will tell you exactly what kind of repair you need.

If the problem is in the cable, then this fix is ​​relatively simple: the wizard will open your iPhone and reconnect the digitizer cable to the logic board.

If the LCD is broken, this is another story, but it is doable. Replacing the screen (display) iPhone (Kiev) in the Apple Service Center "iMobi" will be made quickly and inexpensively using original parts.

Repairing your iPhone yourself is a bad idea.

IPhone users should not open the gadget on their own. Just take a look at the two screws next to the charging port of your iPhone. they are star-shaped! This, as they say, is an excellent repair manual.
