You hit the shutdown button, but Xiaomi Mi TV continues to glow, hovers on the logo or does not respond at all to commands from the remote? This problem is familiar to many owners of smart TVs of the brand โ from budget Mi TV 4A to flagship Mi TV Q2. The causes can be hidden in software failures (frozen firmware, application errors) and hardware malfunctions (power supply, power button). In this article, we will analyze all possible scenarios, including forced shutdown, resetting and breakdown diagnosis โ with step-by-step warnings and warnings of risks.
It's important to understand that if the TV doesn't turn off, it's not always critical. For example, hanging on the boot screen after a software update is often solved by a simple reboot, whereas the constant glow of the indicator without responding to the remote can indicate a motherboard failure. We structured solutions from the simplest (reboot through the button) to the radical (disassembly of the case), so that you can act in stages - without unnecessary risks and financial costs.
1. Forced reboot through the power button
The most secure and versatile way is to get a hardware reset using a physical button on the body. On all Xiaomi Mi TV models (except Mi TV Stick), the power button is located either on the back (right or left of the connectors) or under the logo at the bottom.
- ๐ Turn off the TV power from the socket for 30 seconds (this will reset the residual charge of the capacitors).
- ๐ฑ๏ธ Press and hold the power button on the body for 10-15 seconds (until clicking or changing the indicator).
- โก Connect the power cable back and try to turn on the TV with a button or remote control.
If the button is unresponsive or not (as on some Mi TV P1) models, try an alternative method:
- Turn off the TV.
- Press the button "Menu" on the remote (or "Home" on models with Google TV).
- Without releasing the button, plug the power back in and hold for another 10 seconds.
๐ก
On some Xiaomi TVs, the power button is paired with a control joystick. If it's recessed in the case, use a paper clip or toothpick to press.
This method works in 80% of cases of freezes associated with:
- ๐ฑ App failure (such as Netflix or YouTube ").
- ๐ Failed firmware update.
- ๐ฎ Conflict with connected devices (prefix, sound panel).
Diagnostics of the remote control and power source
If the TV doesn't turn off but it reacts to buttons on the body, the problem may be in the remote control or the power supply.
Check the batteries in the remote (replace them with new ones)
Wipe the IR transmitter with alcohol
Point the smartphone camera at the remote and press the button โ if the IR signal is visible (blinking), the remote is serviceable
Connect the TV to another outlet (exclude network filter problems)
Try to turn on the TV with another remote (for example, from the console Mi Box)
-->
On Xiaomi Mi TV 4S/4A models, there is a frequent problem with capacitors that swell and cause unstable operation.
- ๐ฅ The TV is spontaneously turned on/off.
- ๐ก The power indicator flashes red or orange.
- ๐ When connecting to the network, you can hear cracking or the smell of burning.
โ ๏ธ Warning: If the power supply makes extraneous sounds or warms up, do not turn on the TV, this may lead to a short circuit.
For models with an external power supply (e.g. Mi TV 4A 32), check the output voltage with a multimeter.
| Model TV set | Power supply voltage (V) | Current (A) |
|---|---|---|
| Mi TV 4A 32" | 12 | 2.5 |
| Mi TV 4S 55" | 19.5 | 3.3 |
| Mi TV Q1 55" | 12 | 5.0 |
| Mi TV P1 65" | 12 | 6.5 |
3. reset to factory settings (Hard Reset)
If the forced reboot doesn't work, the next step is to completely reset your settings, which will delete all your apps, accounts and personal data, but return the TV to working order, and the way you reset it depends on the model:
Method 1: Recovery menu (for Android TV models)
- Turn off the TV.
- Press the "Menu" button on the remote and connect the power.
- Hold the button until the Recovery Mode menu appears (usually 10-15 seconds).
- With the Volume +/- buttons, select Wipe data/factory reset and confirm the selection.
Method 2: Through settings (if the TV is turned on but not turned off)
Go to Settings. โ The device โ Reset โ Reset settings. Enter PIN-code (default 0000 or 1234).
What if the TV asks for a password after resetting?
โ ๏ธ Note: On Google models TV (Like Mi. TV Q2) Reset can block the TV with a request FRP (Factory Reset Protection: Without your account data, you can only unlock through the service center.
4.Firmware problems and their solution
One of the common causes of non-turning off is a damaged firmware, which can happen after:
- ๐ Interrupted update (for example, turned off the light during installation of the software).
- ๐ฅ Installation of custom firmware through ADB.
- ๐ ๏ธ Incorrect resetting of settings.
Symptoms of damaged firmware:
- ๐บ The TV is turned on, but stuck on the logo of Xiaomi or Android TV.
- ๐ Cyclical reboot (infinite bootloop).
- ๐ซ The remote and buttons on the body do not work.
Decisions:
Option 1: Upgrade via USB (for models with a USB port)
- Download the official firmware for your model from the Xiaomi Support website (choose the version marked OTA or Full ROM).
- Unpack the archive and copy the update.zip file to the flash drive (FAT32 format).
- Put the flash drive in. USB-port of the TV, press the button "Menu" on the remote and connect the power.
- From the recovery menu, select Apply update from USB.
Option 2: Fastboot firmware (for advanced users)
Requires a PC with ADB drivers installed and a USB-A-USB-A (or OTG) cable.
1. Connect the TV to the PC via the USB- port.
2. Press the "Menu" button on the remote and connect the power (to log into the Fastboot).
3. In the PC command line, do:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot reboot๐ก
Fastboot firmware deletes all data and can result in a loss of warranty, and use this method only if other methods have failed.
5. Hardware malfunctions: when repairs are needed
If none of the software methods worked, the problem is probably hardware.
| Malfunction | Symptoms | Decision |
|---|---|---|
| Power supply failure | The TV doesn't turn off, the indicator flashes red, crackling is heard | Replacement of the power supply unit (cost 1,500โ4,000) โฝ) |
| Maternity board malfunction | TV turns on, but no image, buttons don't work | Diagnostics in the service (repair or replacement of the fee) |
| Problems with the power button | The button is either triggered or not triggered. | Cleaning contacts or replacing a button |
| Processor overheating | The TV is spontaneously turned off and turned on | Cleaning from dust, replacing heat paste |
Self-repair is possible only with experience with electronics. For example, replacing capacitors in the power supply is a relatively simple procedure, but requires a soldering iron and knowledge of circuitry. For other cases, we recommend contacting an authorized Xiaomi service center.
โ ๏ธ Note: Disassembly of the TV body will void the warranty if it is still valid. Before repair, check the warranty period (usually 12 months from the date of purchase).
6. Prevention of hangings in the future
To avoid repeated shutdown problems, follow the guidelines:
- ๐ Regularly update the firmware through Settings โ On TV. โ Updating the system.
- ๐งน Clean the cache once a month: Settings โ Annexes โ Clear the cache.
- ๐ Use a network filter to protect against voltage surges.
- ๐ ๏ธ Clean the air vents from dust every six months (especially for models with active cooling, such as Mi). TV Q1).
- ๐ด Do not connect uncertified devices (cheap consoles, cables) to the TV. HDMI screenless).
Also avoid:
- โ Simultaneously run multiple โheavyโ applications (e.g. YouTube) + Netflix + play).
- โ Interrupting firmware updates.
- โ Use remotes from other devices (even if they are from Xiaomi).

On models with Google TV (e.g. Mi TV Q2), turn off automatic app updates in the background: Settings โ Apps โ Auto-update. This will reduce the load on the system.
