The new iPhone 14 offers one of the best displays of high DPI. It has also ensured maximum safety for its users by putting gorilla glass in both the back and the front. However, not all damage to the display comes from dropping the device from the hands and shattering it. Some users of the iPhone 13 Pro Max have reported a sudden black screen with no prior damage history. The No light on Display issue of the iPhone 14 is where the user can’t see what’s happening on the phone. The phone is running okay. The phone vibrates and the user can hear the notification sounds and other inputs. But the problem is they can not see any of it because the phone display is just plain black. The phone will respond or might even have incoming calls.

The key symptoms of the “No light on Display” issues are:

The phone's display boots up with an Apple logo but doesn’t get past the black screen (iPhone 6 – 8Plus) 

The phone has calls and notifications but doesn’t show anything on display

iPhone can charge (you can hear the sound that the phone makes while charging) but won’t show anything on the display

This “No light on display” is usually an internal issue with the LCD connector. However, Apple recommends some processes to practice on your phone to make sure the black screen is not a software glitch.

Force Restart your iPhone. (Press the volume up (+) and volume down (-) and then press and hold the power button until the Apple logo appears on the screen) 

Connect the lightning cable and charge it for 10 minutes. Then try force restarting the iPhone

UNCONVENTIONAL: Press the screen into the phone so it may reconnect to any dislodged LCD connector. This fix is not recommended, however, it resolved a lot of the user's Black Display issues. It might be risky for any layman.
