You are in the middle of an important call, scrolling through Instagram, or just about to crush your opponents in BGMI. Suddenly, a blackout and… nothing. The OnePlus 9RT goes completely black. The phone is still on, as you can hear notifications, and the buttons light up when you press them. Even calls still ring, but the screen stays dead. No cracks, no drop, no warning. Just a blank, lifeless display staring back at you. If this sounds familiar, you might be dealing with a OnePlus 9RT screen blackout issue. This has been a common issue for the model units manufactured between late 2021 and mid-2022. Thousands of users on OxygenOS 12, 13, and even 14 have reported the exact same problem.
Let’s dive in and understand why it happens so that we can find a reliable solution for it.

What Causes The OnePlus 9RT Screen Blackout Issue?
Here are the most common situations where your OnePlus 9RT screen may go black:
1. Temporary display driver crash / GPU hang: The Adreno 650 GPU or display stack malfunctions. It might happen under load, like gaming, high brightness, or using 120Hz.
2. Loose or oxidised display flex cable: Over time or due to minor flexing of the frame, the connector inside loosens. It could be just enough to lose contact.
3. Motherboard-level display IC failure: The PMIC (power management IC) or the dedicated display power chip starts failing intermittently, then permanently.
4. Software corruption after an update: OxygenOS updates have occasionally bricked the display controller.
The good news? In many cases, you can bring the screen back yourself in under 5 minutes. The bad news? If it’s hardware, it will eventually come back until properly fixed.
