The black screen on Xiaomiβs device is one of the most common problems faced by users of both smartphones and TVs, and the causes can range from a trivial battery discharge to serious hardware failures. In this article, we will explore all the possible ways to turn on the screen, from simple actions to methods for experienced users.
It's important to understand that the algorithm depends on the type of device. For example, for a Redmi Note 12 smartphone and a Mi TV Q2 TV, the approaches will be fundamentally different. We'll look at both cases, and we'll give you recommendations for diagnosing the problem. If the screen never worked after reading this article, you'll probably need professional repairs.
Before you start to act, check the obvious: is the device charged, is the power cable damaged, is there any physical damage to the screen, sometimes the problem is solved in literally 30 seconds.
1. Standard screen turn on on Xiaomi smartphones
If your Xiaomi, Redmi or POCO doesnβt respond to the power button, start with the basic methods. 60% of the time, the problem is solved by one of these methods:
- π Charge the device. Connect the smartphone to the original charger and wait 15 to 20 minutes. Sometimes the battery is dead, you can't even turn on the screen to show the level of charge. Try using another RAM or cable, maybe the problem with the accessories.
- π Forced reboot: Press the power button and volume up simultaneously for 10 to 15 seconds, POCO F5) The combination may be different: + If the smartphone vibrates or the Mi logo appears, release the buttons.
- π± Connect to a PC. Connect the phone to a computer via USB. If the device is defined (for example, as Mi Phone in Device Manager), then the problem is in the screen or its backlight, and not in the brains of the smartphone.
If after this manipulation, the screen still doesn't turn on, but the smartphone is showing signs of life (vibration, sounds, PC-defined), move to the next section. If there is no reaction at all, the motherboard or battery may be faulty.
β οΈ Warning: Don't try to disassemble your smartphone yourself if you don't have experience! Incorrect battery extraction can lead to short circuit or fire. Xiaomi service centers use special tools and protective cases for such cases.
2.Screen activation on Xiaomi TVs (Mi TV, Redmi TV)
Xiaomi TVs often suffer from power problems due to firmware failures or power supply malfunctions. Unlike smartphones, there are several unique diagnostic methods:
- Check the power indicator. There's an LED on the front of the TV: π’ Green lights β the TV is on, but the screen is inactive (maybe the problem is in the backlight or the matrix). π΄ Flashes red - the device is in standby mode or an error has occurred (the number of blinks will tell the malfunction code). β« Does not burn at all - no power (check out the socket, cable, network filter).
Hard reset.

On Xiaomiβs 2020-2023 TVs, resetting to factory settings via the service menu is only possible with the original remote! Universal remotes often do not support combinations for entering Engineer Mode.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The screen is black, but there's sound. | Failure of the backlight or matrix plume | Replacement of illumination or diagnostics in the service |
| The TV does not respond to the remote and buttons | Firmware failure or power supply | Hard reset or check of the power supply |
| The indicator blinks 3 times and goes out | Memory error (eMMC) | Flip or replace the memory chip |
| The screen turns on, but after 2-3 seconds it goes out. | Overheating or inverter failure | Cleaning from dust or replacing the inverter |
π‘
If the Xiaomi TV doesn't turn on after a thunderstorm or power surge, don't reconnect it to the network! this could be a sign of damage to the power supply.
3. Checking of hardware faults
If the software methods didn't work, maybe the problem is the hardware.
- π Cable and connectors. Check the power cable for damage. Check the connector on your smartphones. USB-C β Often it gets clogged with dust or dirt, which interferes with normal exercise. Carefully clean it with a wooden toothpick (not a metal object!).
- π Battery (for smartphones) If the battery is swollen or deformed, it needs to be replaced. Signs of a "dying" battery: The phone only turns on when the charger is connected. The charge drops from 50% to 1% in a few minutes. The device spontaneously turns off at 20-30% charge.
- π± Trains and connectors. On Xiaomi TVs, the plume of the matrix or the backlight inverter often leaves. If you're an electronics expert, you can gently open the back cover and check the density of the connections. On smartphones, the display plume can damage after a fall.
You can use a test menu to diagnose a smartphone, and you can get into it:
1. Turn off the phone (if it responds to buttons).
2. Squeeze the combination: Volume up + Nutrition (on some models Volume down + Nutrition).
3. In the menu that appears, select Test Mode or Diagnostics.
4. Pass tests of the display, battery and sensors.β οΈ Warning: If after the smartphone crash, the screen starts showing vertical stripes or βartifactsβ (colored spots, flickering), do not try to turn it on repeatedly! This can be a sign of damage to the matrix, and further attempts will only make the situation worse. In Xiaomi services, for the replacement of the matrix on Redmi Note models, they take from 3,000 to 8,000 rubles (depending on the model).
4. Resetting settings to factory
If the screen is not turning on, but the device is showing signs of life (vibration, sounds, PC detects), you can try resetting the settings, which will help in cases where the problem is caused by a software failure.
For smartphones:
- Turn off the device (if it is on, press the power button before turning off).
- Press the combination of Loudness up + Power and hold for 10-15 seconds until the Mi logo appears.
- In the Recovery menu (manage volume buttons, choose power button) select Wipe Data β Wipe All Data.
- Confirm the action and wait until the process is complete.
For TVs:
On Xiaomi TVs, the reset is performed through the service menu:
1. Turn the TV off the socket.
2. Press the Menu button on the remote and, holding it, turn the TV on the network.
3. In 5-10 seconds, the service menu will appear.
4. Select Factory Reset (navigation β volume buttons, choice β OK).
5. Confirm the reset and wait for the reset.Make sure the device is charged at least 50 times%|Save important data (photos, contacts) to your PC or cloud|Prepare the original cable and charger|Know the username and password from the Mi Account (required after resetting)-->
Once reset, the phone or TV will return to factory settings, require a reset of Mi, Wi-Fi and other settings, and reset the original settings (language selection, network connection, etc.) on TVs.

Setting reset removes all data from the device, including photos, apps and accounts. If the screen is not working, but the phone is determined by the PC, try extracting data first through the Mi PC Suite program.
5. Alternative ways to turn on the screen
If standard methods don't work, you can try less obvious solutions, which are suitable for power users or when other options are exhausted.
- π§ Connecting to an external display (for smartphones).Some Xiaomi models (such as the Black Shark or the flagship Mi) support image output via USB-C β HDMI. Connect your phone to a monitor or TV with an adapter, and if you see a picture on the outside, the problem is the display of your smartphone.
- π‘ Remote control (for TVs) If the TV is connected to the same Wi-Fi network with the phone, try controlling it using the Mi Home or Mi Remote app. Sometimes the screen does not turn on due to a malfunction in the interface, but the TV itself works.
- π Fastboot Firmware (for smartphones). If the phone is detected by a PC in Fastboot mode (checked by the fastboot devices team in the terminal), you can try reflashing it using the Mi Flash Tool. This method requires skills and is only suitable for devices with an unlocked bootloader.
For Xiaomi TVs, there's another non-obvious way to turn on your voice assistant. If you have Alice or Google Assistant set up, try saying,
"Okay, Google, turn on the TV [device name in Mi Home]."Sometimes this works even when the remote and buttons donβt respond.
What if the screen is turned on but is not working properly?
6. When to contact the service center
If none of these methods worked, it's probably a hardware problem, and here are some signs you should call the professionals:
- π₯ Physical damage, cracks on the screen, dents on the body, traces of fluid inside the device.
- π₯ Smell of burning or foreign sounds, characteristic smell of scorched electronics or crackling when switched on.
- β‘ Power problems: The device does not charge, discharges quickly or turns off when connected to the network.
- π₯οΈ Artifacts on screen: constant stripes, flickering, distorted colors or broken pixels.
In Xiaomi service centers, diagnostics are usually free, and repairs are cheaper than in informal workshops.Average repair prices (in Moscow, 2026):
| Service | Smartphone | Television |
|---|---|---|
| Replacement of the display (matrix + touchscreen) | 4,000 β½ | 8,000 β½ |
| Repair of the power supply unit | 2,500 β½ | 3,500 β½ |
| Battery replacement | 1,500 β½ | β |
| Flashing (if the software fails) | 1,000 β½ | 2,000 β½ |
Before visiting the service, do the following:
- Take a picture of the serial number of the device (usually it is listed on the box or under the battery).
- Check if the warranty is maintained (check checks or Mi Account).
- If the screen responds to touch, but does not show the image, write down the password from the phone on the recorder - this will speed up the diagnosis.
7. Prevention of screen problems
To avoid problems with turning on the screen in the future, follow these guidelines:
- π Use the original chargers. Cheap Chinese RAMs can cause power surges that damage the screen or battery.
- π± Update the firmware. In new versions. MIUI PatchWall (for TVs) often fixes display-related bugs.
- π‘οΈ Install covers and windows. Even a minor impact can damage the plume of the display.
- π‘οΈ Avoid overheating. Do not leave your smartphone in direct sunlight or close the TV's vents.
For Xiaomi TVs, it is especially important to:
- π Use a network filter. Power surges are a common cause of power failure.
- πΉοΈ Don't press buttons on the remote too hard, it can lead to contacts sticking up.
- π§Ή Clean dust regularly, and the accumulation of dust on boards can cause short circuits.
