Why the screen on Xiaomi phone does not work: a full analysis of the causes and solutions

Xiaomi smartphone screen stopped responding to touch or completely went out for no apparent reason, POCO And Mi, regardless of the year it was produced, and 70 percent of the time it was software failure, but sometimes it was physical damage or wear and tear. In this article, we will analyze all possible causes - from the banal discharge of the battery to damage to the plume, as well as give step-by-step instructions for diagnosis and repair.

It's important to understand that if the screen doesn't turn on, but the phone makes sounds or vibrates, that's one scenario: if the device is completely dead (no response to charging, buttons), it's a completely different scenario. We'll look at both cases, and we'll also focus on the typical problems for popular models: Redmi Note. 10/11/12, POCO X3/X4/X5, Mi 11/12. Spoiler: In 30% In some cases, a simple reboot helps, but there are more complex situations that require the intervention of a service center.

1. Software failures: when the software is to blame

If Xiaomi's screen isn't working, but the phone is showing signs of life (sounds, vibrations, lights), there's a 60 percent chance that the problem is software.

• 🔄 System freeze after update MIUI It is often found on models with 4-6 GB of RAM when working with heavy games or multitasking.
• 📱 Firmware conflict – for example, after manual downgrade version MIUI or incorrect installation of custom recavery (TWRP).
• 🛑 Critical launcher failure (shell) MIUI), When the system cannot load the GUI, but the kernel is running.
• 🔋 Deep battery discharge, after which the power controller blocks the screen from turning on before recharging.

How to diagnose? Connect your phone to a charger (preferably an original charger) and pay attention to:

• 🔌 Charging indicator: if it burns or flashes - the problem is more software.
• 🔊 Sounds/vibrations when pressing volume or power buttons.
• 💻 Computer reaction: if you connect to the USB The device is defined as Qualcomm HS-USB QDLoader 9008 is a sign of a “brick” (firmware failure).

If you suspect a software failure, try a hard reboot:

1. Press the Power + Volume button for 10-15 seconds.
2. If the Xiaomi logo appears, release the buttons. The phone will reboot.
3. If there is no reaction, plug it into charging for 30 minutes and try again.

💡

If the screen is up after the reboot, but the problem is repeated, it's because of unstable firmware or application conflict, and you need to reset or flash it.

2. Hardware breakdowns: plume, matrix, controller

If Xiaomi’s screen doesn’t turn on even after the reboot, and the phone doesn’t show signs of life (no vibration, no sounds, no charging indication), it’s likely a physical breakdown.

How to check hardware breakdown without disassembling the phone?

• 🔦 Lighting with a flashlight: light up at an angle. If you see a dim image, the problem is the backlight or the plume.
• 🎧 Connect headphones: if the sound is played (for example, when you call), but the screen does not respond - this confirms a hardware malfunction.
• 🔌 Check on another charger: sometimes the power supply does not give enough voltage to turn on the screen.

💡

If the phone falls or gets wet, don't try to turn it on! This can cause a short circuit, it's better to immediately take it to the service for diagnosing moisture-resilient stickers (they turn red when in contact with water).

3.Typical issues for popular Xiaomi models

Some Xiaomi smartphones have "congenital" screen-related diseases, and this is what most often breaks down in popular lineups:

• 📱 Redmi Note 10/11/12: The detachment of the plume due to the thin body manifests as a flicker of a screen or stripe when you press the top of the display.
• 📱 POCO X3/X4/X5: Overheating of the screen controller during long games. The screen goes out, but the phone continues to work (sound is there).
• 📱 Mi 11/12: The exit AMOLED-post-matrix 1.5–2 Symptoms: green/purple stripes, broken pixels.
• 📱 Redmi 9A/9C: Oxidation of contacts due to weak moisture protection.The screen periodically "gluts" after moisture is hit.

For models with a high refresh rate of the screen (90 Hz, 120 Hz, 144 Hz), a typical problem of overheating of the GPU. POCO F3 redmi K40 The screen may suddenly go out during games due to trottling (automatic performance decline:

1. Reset the graphics settings in Settings → Display. → Frequency of update.
2. Turn off High Performance Mode in Settings → Battery.
3. Update the firmware to the latest version MIUI (In new versions, bugs with overheating have been fixed).

4.What to do if the screen does not respond to touch (touch does not work)

Situation: the screen is on, the image is there, but the sensor is not responsive to touch, and the reasons may be both software and hardware.

Turn off the protective film/glass (sometimes it interferes)

Put the mouse on. OTG (If the cursor is moving, the sensor is a problem)

Check the work in safe mode (clip the power supply) → Safe regime)

Update the firmware through Settings → The phone. → Updating the system-->

If the sensor is not working partially (for example, only the top or bottom of the screen is not responding), this is a sign of:

• 🔧 Damage to the plume (most often after falling).
• 💧 Moisture entering the screen (oxidation of contacts).
• 🛠️ Poor repairs (if the display has recently been changed).

For a temporary solution, you can connect USB-mouse-wise OTG-It allows you to use the phone until you fix the sensor, and if it's software, it helps:

1. Resetting settings through Settings → Memory. → Resetting settings.
2. Remove the last installed applications (they may have conflicted with the sensor driver).
3. Fastboot flashing (instruction below).

💡

If the sensor stops working after the update MIUI, A rollback to a previous firmware version often solves the problem.Use the official Mi Flash Tool for downgrade.

5. How to reflash Xiaomi if the screen isn't working

If the Xiaomi screen is not turned on, but the phone is determined by the computer in Fastboot mode or EDL, You can try to reflash it manually:

• 🔄 After a failed update (brick).
• 📱 Bootloop (Bootloop) Failure (Infinite Reboot).
• 🛠️ Damage to system files.

You'll need:

• 💻 Windows computer.
• 🔌 Original. USB-cable (not a cheap replacement!).
• 📦 Firmware for your model (download from the official Xiaomi website).
• 🛠️ Mi Flash Tool (for Fastboot) or QFil (for Fastboot) EDL).

Instructions for firmware via Fastboot:

1. Turn off the phone (press the power + Volume down for 10 seconds).
2. Press Power + Volume Down to enter the Fastboot (a hare in a hat-out of a hat will appear).
3. Connect your phone to your PC and start the Mi Flash Tool.
4. Select the downloaded firmware (file with the extension.tgz).
5. Press Refresh, then Flash. Wait until it's finished (5-10 minutes).
6. After the reboot, the screen should be working.

⚠️ Attention, firmware through EDL (Emergency mode) requires authorization of Xiaomi account and can lock the phone if it was tied to another user.

💡

If the Mi Flash Tool gives you a "Couldn't find device" error, install Qualcomm drivers manually through Device Manager (Other Devices section).

6. When to contact the service: prices and risks

If all of these methods did not work, only repairs at the service center remain, and here are the approximate prices for replacement components for Xiaomi (2026):

⚠️ Don't trust repairs to unofficial workshops if you don't:

• 🔧 They offer a screen replacement for 1,000 to 2,000 ₽ (Probably using used parts).
• 📄 Refuse to give a guarantee for work (minimum 3 months - standard for certified centers).
• 🔨 They say that “fix indiscriminately” (often this means a temporary solution, for example, heating the plume with a phenome).

Official Xiaomi service centers in Russia can be found on the website mi.com/ru/service. Please clarify before your visit:

• 📋 Original spare parts for your model.
• ⏳ Repair period (during peak periods can reach 2-3 weeks).
• 💰 The cost of diagnosis (in some centers it is paid, even if you refuse to repair the car).

7.How to prevent screen failure in the future

To make Xiaomi’s screen last longer, follow the simple rules:

• 🛡️ Use a high-quality protective glass (like a Spigen or Nillkin) that can crack on impact and damage the matrix.
• 🔋 Don't discharge the phone to 0% Deep discharge increases the load on the power controller, which can cause screen crashes.
• 🌡️ Avoid overheating.Do not leave your phone in the sun or near heat sources (e.g., on a car torpedo).
• 💧 Protect against moisture, even if the model has protection. IP53, Long-term contact with water will lead to oxidation.
• 📲 Update the firmware. In new versions. MIUI Frequently fix bugs associated with display drivers.

For models with AMOLED-screens (Mi 11, Redmi) K50) particularly:

• 🔄 Turn off Always-On Display (constantly burning screen reduces matrix life).
• 🎮 Limit FPS in games (constant 120Hz work accelerates wear and tear).
• 🌙 Use dark topics (on the other hand) AMOLED This reduces energy consumption and heating).

💡

If you drop your phone frequently, consider Gorilla Glass Victus-enabled models (e.g. Xiaomi). 13T or POCO F5). They can withstand falls from a height of up to 2 meters.
