Modern smart TVs running on the Android TV operating system are complex computing devices that require periodic maintenance. Owners of Xiaomi Mi Smart TV often face a situation when the interface begins to respond to commands with a delay, applications stop closing or the soundtrack disappears completely. In such cases, the first and most effective step to restore normal operation of the gadget is to properly restart the system.
Many users mistakenly believe that it is enough to simply turn off the device with a button on the remote, but in modern models this action most often puts the technique in deep sleep mode, rather than stopping all background processes.
Understanding the difference between a conventional shutdown and a full reboot will help you solve minor software failures faster without going to service centers. We will break down standard methods through menus, options using physical housing buttons, and ways to recover from a full freeze.
Staff reboot through the settings menu
The safest and most recommended method by the manufacturer is to use the built-in programming interface, which ensures that all running applications and system services are properly terminated before the power is turned off. To perform the procedure, you need to take a remote control and press the button with the image of the gear to call a quick menu.
In the list that opens, select Settings, then go to About the device or System, depending on the version of the MIUI for TV firmware. This is where key power management options are hidden, which allow you to perform a soft restart without losing user data and settings.
Next, you need to find the option to turn off or restart. In some versions of the software, this feature can be hidden in the power saving submenu. Once you select the appropriate item, the system will prompt you to confirm the action, and after a few seconds the screen will go out and the device will start the restart cycle.
💡
Using a software menu is the only way to ensure the integrity of the file system when you plan to restart your TV.
Importantly, this method is not suitable for situations where the interface is completely frozen and no longer responds to the pressing of the remote buttons, in which case you will have to resort to more radical but effective methods of hardware impact on the device.
Forced reboot of the power button
If the software interface is not available, a physical control button located on the TV body comes to the rescue, and most Xiaomi Mi TV models have it on the bottom or back, often hidden from view to avoid disturbing the design aesthetic, and this button allows you to initiate an emergency shutdown.
To perform a hard reboot, press and hold the power button on the case for 5-10 seconds, at which point a system menu may appear on the screen suggesting you choose an action, or the TV will simply turn off. If the device is turned off, release the button and press it again with a short press to turn on.
- 🔌 Find a physical power button on the TV body, often marked with a circle symbol with a vertical line.
- ⏱️ Press and hold the button for 10 seconds, ignoring any pop-up menus on the screen.
- 🔄 Wait for the indicator to be completely wiped out and the Android or Mi logo to reappear.
There is also an alternative method that works on some firmware versions: a brief press of the power button calls a menu where you can select Reboot via volume buttons or navigation on the case, which is less traumatic to the system than a complete shutdown.
Why does the button on the remote not always work?
Method of complete de-energization of the device
In cases where neither software methods nor buttons on the case are responsive, the only proven option is a complete power outage, which allows you to reset static electricity and clear the memory cache that could overflow and cause a lock.
The procedure requires physical availability to the outlet or the network filter, and you have to pull the power cord out of the network and wait a certain amount of time, which is a critical step, because the capacitors inside the TV have to run out completely to reset all the time parameters.
☑️ Right de-energization
After waiting for a pause of 2-3 minutes, connect the power cable back. Note that the first start after a complete shutdown can last longer than usual, as the system takes time to check the integrity of files and load drivers.
⚠️ Warning: It is not recommended to use the method of pulling the cord out of the socket as the main way to turn off the TV. Frequent sudden power interruptions can damage the file system or cause the power supply to fail.
This is particularly effective for Wi-Fi problems, when the TV stops seeing wireless networks, or for strange image artifacts. Complete energy loss often "cures" small logic errors of controllers.
Use of Engineering Menu and ADB
For advanced users who are not afraid to experiment with system settings, there is the possibility of rebooting through debugging interfaces. This is especially true if the standard menu is locked or not working correctly. Access to advanced features is often through hidden combinations or remote connection.
One way to do this is to use the Remote ADB Shell app on a smartphone that's connected to the same Wi-Fi network as the TV. If the TV has USB debugging enabled, you can send a command to reboot directly.
rebootThere is also a way to log into the hidden menu through the date and time settings or through the About Device section by repeatedly tapping the build number, although this works less frequently on Android TV than on smartphones. If you managed to activate the developer mode, you will have access to deeper process management.
- 📱 Install an application for ADB-Connection to your smartphone or PC.
- 🌐 Make sure that both devices are on the same local network.
- 💻 Enter. IP-Address and execute the command adb shell reboot.
Using these methods requires caution. Incorrect actions in the engineering menu can lead to resetting all settings or even “bricking” the device, so use this option only in extreme cases.
Resolving interface freeze problems
Frequent freezes in the PatchWall interface or the standard Android TV shell can be caused not only by temporary memory overflow, but also by conflicts of installed software. If a simple reboot only helps for a short time, it is worth conducting a deeper diagnosis.
Check the installed list first. Often, problems are caused by heavy launchers, antiviruses, or memory cleanup applications that paradoxically only strain the system. Deleting suspicious software often solves the problem without the need for frequent reboots.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| TV's slowing down on menu | Cache overflows | Cleaning the cache in the storage settings |
| The remote is down. | Bluetooth module failure | Complete shutdown for 5 minutes |
| Black screen, there's sound. | Video driver error | Resetting image settings or flashing |
| Self-involved reboots | Overheating or power supply | Ventilation and socket check |
Also, you should pay attention to the free space in the internal memory. If the storage is more than 90% full, the Android system begins to work extremely unstable, freeing up space or installing a flash drive as additional storage can significantly improve performance.
Resetting to factory settings as an extreme measure
If none of the reboot methods fixes persistent bugs and malfunctions, a complete system reset to factory status may be required, a procedure that will remove all your accounts, installed apps and personalized settings, returning the TV to the “out of the box” state.
You can reset via the Settings → Device → Reset. Before starting the process, the system will alert you to the loss of data. Make sure you remember your Google account details, as after the reset, you will need authorization to work with smart functions.
⚠️ Before performing a full reset (Factory Reset), be sure to write down the licenses and passwords from important applications, since it will not always be possible to restore them automatically.
Once the reset is complete, the TV will restart and start the initial setup, which can take up to 15 to 20 minutes, and don't interrupt it and wait for the desktop to appear.

Before reset, take a picture of network settings and image calibration to quickly restore the usual color reproduction after the reinstall system.
