I’m hesitant to write this because it is by no means a hard and fast rule, but I have noticed a pattern in my experience working with iPhones. How Do I Know Whether My Display Is Dislodged Or Broken? 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. There are other cases where the fix isn’t so simple, and that’s when the LCD itself is damaged. 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. In many cases, your iPhone screen is black because the cable that connects the LCD to the logic board has become dislodged. The black stick is touching the display data connector 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. It digitizes your finger, which means it turns the touch of your finger into a digital language your iPhone can understand.Įach component of your iPhone’s display has a separate connector that plugs into your iPhone’s logic board. The digitizer, which is the part of the display that processes touch.The LCD screen, which displays the images you see on your iPhone.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: The display shows you the images you see, but the logic board tells it what to display. The logic board is the brains behind the operation of your iPhone, and every part of your iPhone connects to it. There are two pieces of hardware that we’ll talk about: Your iPhone’s display and the logic board. Let’s Take A Look Inside Your iPhoneĪ brief tour of the inside of your iPhone will help you understand why your screen is black.
If the Apple logo doesn’t appear on the screen, keep reading. Check out my other article on frozen iPhones, which will tell you exactly what to do to fix your iPhone.
If the Apple logo appears on the screen, there probably isn’t a problem with your iPhone’s hardware - it was a software crash. this thread has a good number of replies compared to what I've read of older phones tbh.On the iPhone 7 or 7 Plus, you perform a hard reset by pressing and holding the volume down button and the power button at the same time until the you see the Apple logo appear on the screen.Īnd if you have an iPhone 8 or newer, perform a hard reset by quickly pressing and releasing the volume up button, then quickly pressing and releasing the volume down button, and then pressing and holding the power button (iPhone 8) or the side button (iPhone X or newer) until that Apple logo appears. At least, I think it should be looked into.
But it's definitely happened more on the 12 Pro for me compared to my old 5s, 6s, and Xs, not once did those phones get dim unless the phone or the environment were obviously warm. Maybe I'm unlucky and the other replies are overheating issues, I'm not sure. Maybe the phone is really overheating in just that one moment in some weird programming logic way, or it simply a bug/hardware issue. After pressing the sleep button once and waking the phone, the screen was at normal brightness like normal. Brightness slider at max was still really dim, bringing it down makes the screen barely visible. Now with my 12 Pro, after just plugging the phone indoors to charge and starting up a game, the phone instantly went dim as if it were overheating which is strange because the phone wasn't warm the sun wasn't out nor was I outside to begin with. I understood the screen went dim because the phone was warm and I was using it more than normal in hot temperatures.
For me, whenever I was outside in ~90 degree F while doing something intensive on the phone with full brightness, AKA in music with GPS, intensive app game, steaming.
I'm familiar with the iPhones turning dim while overheating, but it's pretty clear when this happens.
