Iphone 13 Black Screen Troubleshooting Guide
iPhone 13 Black Screen Troubleshooting Guide
Take away an iPhone’s screen, and you’ve lost almost all ability to interact with it. The same goes for inability to see anything on your screen. Even if touch is working, it’s hard to know what your touch is doing without an image to accompany it. So, if your iPhone is stuck in this state, where do you start?
Before undertaking any of the more time-consuming solutions below, these are a few fundamentals to get you going. Perform a force restart to ensure that your iPhone is not simply frozen.
Firmware Corruption
It is rare for an iPhone to develop issues producing an image because of a software issue. But an iPhone in Direct Firmware Upgrade mode, or DFU mode, manifests with no image on the screen, only the backlight may be on. Since the iPhone 13 makes use of an OLED type display, there is no backlight, so this could be expected behavior. If your phone is stuck in this state, this could point to an issue with firmware.
Ambient Light Sensor Fault
Along with the front-facing camera, a host of other sensors populate the top edge of the display. The Ambient Light Sensor, or ALS, is responsible for setting the screen’s auto brightness. The screen may not be black, just dim.
Screen Disconnect
Especially after a hefty drop, the connection between the board and the screen can become separated. It is uncommon, but still worth going through the motions of a simple iPhone 13 Screen Replacement.
Faulty Display
Although most display failures seem obvious, even without visible damage, the display may not work properly due to something amiss internally. Cracks in glass can also be difficult to detect until the light catches them.
OLED Oxidation, Organic LED, or OLED display panels like one the iPhone 13 uses, are quite sensitive to oxygen exposure. The Organic LEDs themselves have a tendency to oxidize rapidly, causing them to quit functioning. A black splotch on your phone’s display is likely to be damage of this variety, even in the absence of a crack.
Logic Board Malfunction
The logic board is the hub for the vast majority of an iPhone’s functionality. Any number of the small components on the board may have failed or become damaged and is a safe assumption of cause if nothing else on this page has worked.
