The black screen on Xiaomi is one of the most frightening malfunctions a user can encounter: the phone doesn't respond to pressing, doesn't light up the screen, but it probably vibrates or makes sounds, or is the device completely dead and doesn't show signs of life? In both cases, you shouldn't panic: in 80% of situations, you can solve the problem yourself without resorting to expensive repairs.
In this article, we will look at all possible causes of black screens, from the banal discharge of the battery to serious hardware failures, you will learn how to diagnose a problem, which manipulations should be tried first, and when it is better to carry the phone immediately to the service center. We will pay special attention to Redmi models, POCO and flagships Xiaomi 12/13/14, They have specific βdiseasesβ associated with firmware and iron.
Important: If your Xiaomi falls into the water, hits or overheats before the black screen appears, immediately go to the section on hardware breakdowns. Otherwise, start with simple recovery steps.
Why Xiaomi is getting a black screen: 5 main reasons
A black screen rarely occurs by itself, usually preceded by certain events or errors, and the most common causes are grouped by type:
- π Battery discharge or charging problems: Even if you βjustβ charged your phone, contact could break and the power controller could fail.
- π± Software failure (software): βhangβ after update MIUI, Application conflict or damage to system files.
- π Hardware malfunctions: the collapse of the screen plume, failure of the display module or motherboard.
- π₯ Overheating or physical impact: falling, moisture, overloading the processor (e.g. during games).
- π Incorrect update/firmware: interrupted installation process or incompatible version MIUI.
Interesting fact: the POCO F3/F4 and Redmi Note 10 Pro models often have a problem with battery contacts dropping after falls, which leads to the phone only turning on when connected to charging - the screen remains black, but the device vibrates. If your model is on this list, check the battery first.
What to do first: 3 steps to diagnose
Before you take your phone apart or bring it to the service, follow these simple steps to help narrow down the possible problems:
- Check charging: connect your phone to another cable and power supply (preferably the original one), leave at least 30 minutes on charge, even if the indicator is not on, try charging from a computer or power bank.
- Perform a forced reboot: press the power + volume button up for 10-15 seconds. On some models (Xiaomi 12T, POCO X5), the combination may be different: power + volume down.
- Put a flashlight on the screen: if the image is barely noticeable, the problem is in the backlight of the display, not in the module itself. This is a frequent malfunction on the Redmi Note 9/11.
Critical: if the phone vibrates when charging, but the screen remains black, there is a 90% chance that the display plume or controller is the problem, in which case self-repair is only possible if you have experience with soldering equipment.
