Your Xiaomi Mi TV or Redmi Smart TV stopped responding to the remote and the power button? The screen stays black, the indicator doesn't burn, and all attempts to start the device fail? This problem is familiar to many owners of Xiaomi smart TVs, and in 80% of cases it can be solved independently - without going to the service center.
In this article, we'll look at all the possible reasons why the TV doesn't turn on and doesn't show signs of life, from simple firmware failures to hardware malfunctions, how to diagnose a problem, what manipulations are worth trying first, and when it's best to carry the equipment right away for repairs, and focus on hidden recovery functions that are not written about in official instructions, but which are often rescued in critical situations.
If your Xiaomi TV flashes a light or makes sounds but doesnβt show an image, thatβs another case (read our article on black screen with sound), and itβs about the complete βdeathβ of the device when it doesnβt respond to anything other than a forced reset via a service menu or flashing.
1. Primary diagnosis: check the obvious
Before you take down a TV or look for firmware, make sure that the problem isn't trivial. According to service centers, 30% of "not on" complaints are resolved at this point.
- π Power: Check that the cable is connected to the socket and connector DC IN Try another cable or socket -- sometimes the problem is oxidized contacts.
- πΊ Indicator: If there is an LED on the front panel, pay attention to its behavior: β‘ Flashing red β TV in standby or crash. π’ Burning green - possible failure of the matrix or backlight. β« Not burning at all - a problem with a power supply or motherboard.
- πΉοΈ Remote and buttons: try to turn on the TV with a button on the case (usually under the logo or on the side). If there is no reaction, check the batteries in the remote or connect another (smartphone with the Mi Remote app).
If you've been doing this, you've got to move on to the next step, but first, answer the question:
Important! If the Xiaomi TV stopped turning on after a firmware update, thunderstorm or power surge, do not try to turn it on repeatedly. This can aggravate the problem, especially if the memory chip (eMMC) is damaged.
2. Forced reset: how to start a TV without firmware
Many Xiaomi TV models (Mi TV 4/4S/4A, Redmi Smart TV X and later) have a hidden service recovery menu that allows you to reset or restart the system even when you freeze completely.
- Turn off the TV for 10 minutes (this will drain the capacitors).
- Press and hold the power button on the case (not on the remote!).
- Connect the power cable to the socket, continuing to hold the button.
- Hold the button for another 15-20 seconds until the Xiaomi logo or recovery menu appears.
If you do it right, you will see one of two things:
- π Recovery menu (black screen with white text in English).
- π± Android logo TV with spinning animation (meaning the TV is trying to boot up).
From the Recovery menu, select Wipe data/factory reset using volume buttons on the case or remote. After reset, the TV should restart.

Warning: Reset will delete all installed apps, accounts and settings. If the TV was linked to your Mi Account, you may need to enter your login and password after the reset.
What to do if the Recovery menu doesnβt appear?
3. USB firmware: when the TV is "brick"
If the reset didn't work and the TV still doesn't turn on, it's likely that the firmware is damaged.
- β‘ Interrupted update (pulled out the plug or turned off the lights).
- π Viruses in a third-party application (especially if installed) APK source).
- π Memory failure (eMMC) due to overheating or wear.
Recovery will require:
- π₯οΈ Computer with Windows/Mac.
- πΎ USB-drive (flash drive) up to 8 GB, formatted in FAT32.
- π Firmware for your model (you can download on the official Xiaomi website or forums like this) 4PDA).
Firmware instructions:
- Download the archive with the firmware and unpack it. The file name should be in update.zip format.
- Copy update.zip to the root of the flash drive (not to folders!).
- Insert the USB 2.0 port on your TV (usually marked as Service).
- Press the power button on the case and connect the TV to the outlet.
- Hold the button until the update process starts (progress bar appears).
| Model TV set | Firmware reference | Features |
|---|---|---|
| Mi TV 4S 55" | Official page | You need to run a firmware version of MSD6A or newer |
| Redmi Smart TV X55 | 4PDA (registration required) | Supports firmware via OTA and USB |
| Mi TV 4A 32" | Xiaomi Community | Frequent problems with eMMC, may require replacement |
Attention! β οΈ If the TV turns off or the flash drive is removed during firmware, this can lead to a complete loss of performance (the so-called βbrick.

Before you run the firmware, check the checksum (MD5) of the downloaded file, which will prevent the installation of the damaged firmware. Compare the hash with what is listed on the Xiaomi website.
4. Hardware malfunctions: when to carry for repair
If neither the reset nor the firmware helped, the problem is probably the hardware.
- π Power supply: if the TV does not respond to the button and the indicator does not burn, check the voltage at the output of the unit (should be 12V/19V The capacitors or fuses often fail.
- π§ Motherboard: oxidation of tracks, burnt chips or memory chip dump (eMMC). TV 4 often suffers south bridge.
- π Battery (in portable models): if you have Xiaomi Mi TV Stick or Portable TV, check the battery charge.
- πΊ Matrix/backlighting: if the indicator is on, but there is no screen β it is possible that the LEDs of the backlight have burned out or the plume is damaged.
Self-repair of these components requires soldering and diagnostic skills. For example, replacing the capacitors in the power supply will cost 1500-3000 rubles in the service, and soldering eMMC - up to 5000 rubles. If the TV is guaranteed, it is better to immediately contact the authorized service center Xiaomi.
How to choose a service:
- β Official Xiaomi Partners (list on mi.com).
- β οΈ Unofficial workshops with reviews on Yandex.Maps or 2GIS.
- β Avoid garage craftsmen without a license β there is a high risk of getting back the TV with new problems.

If the Xiaomi TV doesnβt turn on after a fall, hit or hit with liquid, donβt try to repair it yourself. In such cases, multiple components are often damaged at the same time, and diagnostics require professional equipment.
5. Alternative ways of inclusion (for advanced users)
If standard methods don't work, you can try more sophisticated options, and they'll be suitable for those who are willing to take apart a TV or work with tech utilities.
Method 1: Starting via ADB (if the TV is visible via USB)
If the TV reacts to your computer connection (e.g., makes a USB connection sound), try running it through ADB:
adb devices
adb shell rebootIf the command is executed, but the TV does not restart, the problem is in the bootloader.
Method 2: Direct connection to UART
For power users, you can connect to the UART service port on the motherboard (usually 4 pins: GND, TX, RX, 3.3V) and send a command to turn on via a terminal (e.g. Putty) Dangerous! Wrong commands can finally kill the TV.
Method 3: Replace the firmware through SPI-flasher
If the eMMC is damaged but the motherboard is intact, you can flash the memory chip with the CH341A programmer and Flashrom software. This method requires soldering and knowledge of circuitry.
Warning! β οΈ All of these methods can lead to a loss of warranty and permanent failure of the TV, and only use them if you understand the risks.
6.Prevention: How to avoid repeated failures
To prevent your Xiaomi TV from dying in the future, follow these guidelines:
- β‘ Use a voltage stabilizer or UPS β power surges kill power supplies.
- π Do not update your firmware over Wi-Fi if the connection is unstable. It is better to download the file to a flash drive and update manually.
- π§Ή Clean the TV from dust every 3 months (especially the air vents in the back.
- π‘οΈ Do not install applications from unknown sources β they may contain viruses that damage the firmware.
- π If the TV is not used for a long time, disconnect it from the socket (but not more often than 1 time a week, so that the capacitors do not discharge).
It is also useful to enable automatic system recovery in settings: Settings β Device β Update and Security β System Restore.
