Your iPhone is on, but the screen is black. Your iPhone rings, but you can’t answer the call. You’ve tried resetting your iPhone, letting it run out of battery and plugging it back in, and your iPhone screen is still black. In this article, I’ll explain why your iPhone screen went black and what you can do to fix it. A black screen is usually caused by a hardware problem with your iPhone, so there usually isn’t a quick fix. That being said, a software crash can cause your iPhone display to freeze and turn black, so let’s try a hard reset to see if that’s what’s going on. To do a hard reset, press and hold the power button (also known as the Sleep / Wake button) and the Home button (the circular button below the display) together for at least 10 seconds.
A brief tour of the inside of your iPhone will help you understand why your screen is black. There are two pieces of hardware that we’ll talk about: Your iPhone’s display and the logic board. The logic board is the brains behind the operation of your iPhone, and every part of your iPhone connects to it. The display shows you the images you see, but the logic board tells it what to display. The entire display of your iPhone is removable, but it’s a lot more complicated than you might think! There are four major components built into your iPhone’s display:
1. The LCD screen, which displays the images you see on your iPhone.
2. The digitizer, which is the part of the display that processes touch. It digitizes your finger, which means it turns the touch of your finger into a digital language your iPhone can understand.
3. The front-facing camera.
4. The home button.
Each component of your iPhone’s display has a separate connector that plugs into your iPhone’s logic board. That’s why you might be able to swipe across the screen with your finger, even though the screen is black. The digitizer is working, but the LCD is not. In many cases, your iPhone screen is black because the cable that connects the LCD to the logic board has become dislodged. This cable is called the display data connector. When the display data connector becomes dislodged from the logic board, your iPhone can be fixed by plugging it back in. There are other cases where the fix isn’t so simple, and that’s when the LCD itself is damaged. When that happens, it doesn’t matter if the LCD is connected to the logic board or not – it’s broken and it needs to be replaced.
How Do I Know Whether My Display Is Dislodged Or Broken?
If your iPhone display stopped working after you dropped it, your screen is probably black because the LCD cable (display data connector) has become dislodged from the logic board.
If your iPhone display stopped working after it got wet, your screen is probably black because the LCD is broken and needs to be replaced.
How to Fix a Black iPhone Screen
The way you choose to proceed may depend on whether your iPhone LCD cable has become dislodged from the logic board or if the LCD is broken. You can use my rule from above to make an educated guess.
If the LCD cable has become dislodged, the Genius Bar at an Apple Store may repair it free of charge, even if your iPhone is out of warranty. That’s because the fix is relatively simple: They’ll open your iPhone and reconnect the digitizer cable to the logic board. If you decide to go this route, make an appointment with the Genius Bar before you arrive – otherwise, you could end up standing around for a while.
If the LCD is broken, that’s another story. It can be very expensive to repair your iPhone display, especially if you go through Apple. If you’re looking for a high-quality, less-expensive alternative, I recommend cellphoneage.com website.
If you’re very tech-savvy, and going to an Apple Store isn’t an option, reconnecting the display data cable to the logic board isn’t that difficult, if you have the right tools. Replacing the display is very complex because of the number of components involved. iPhone 5 LCD screen digitizer replacement
