Modern smart TVs running on Android TV are complex computing devices that, like smartphones or computers, periodically require reboots to work properly. Owners of Xiaomi and Mi TV equipment often face situations where the interface begins to react with a delay, applications stop opening, or the image disappears when the sound is working. At such moments, a standard remote shutdown does not help, since the device simply goes into deep sleep mode, storing errors in RAM.
Properly restarting the system allows you to clear the cache of running processes, reset network settings and force system services to restart. It is not just a power outage, but a full-fledged software restart cycle that eliminates most software failures without losing user data. In this article, we will discuss in detail all available methods, from a regular shutdown through the menu to a hard reset through the engineering menu or physical buttons.
It’s important to understand that regular maintenance of the TV extends the life of its hardware. If your Xiaomi 4K is slow, don’t rush to carry it to the service center. Often the problem is solved by correctly performing the soft reset procedure or cleaning up the memory from temporary files accumulated during operation.
Staff reboot through the Android TV interface
The safest and most recommended reboot method is to use an embedded software menu, which ensures that all active processes are completed correctly and the file system is not damaged. You will need a remote control to perform the operation, since navigation is carried out exclusively through it.
Click the button with the image of the gear on the remote to open quick settings, or find the gear icon in the upper right corner of the main screen. You need to go to the Settings section, then select General or System, depending on the version of the MIUI for TV firmware. In the list that opens, look for the option About TV or About System.
Inside the system menu, find Reboot, the system will request confirmation of the action, and after pressing OK, the screen will go out, and after a few seconds the TV will turn on again, showing the Mi or Android logo.
⚠️ Warning: Do not pull the power cord out of the socket immediately after selecting the reboot item in the menu.
Sometimes the reboot button can be hidden in the Energy Saving submenu. If you don't find it in the basic settings, check this section. It's also worth noting that some remote models have a separate shutdown button, which is briefly clicked on by a menu with a choice of action: Turn off or Reboot.
☑️ Software Reboot Algorithm
Method of forced reboot with remote buttons
If the TV interface is completely frozen and no longer responsive to commands, but the device is on (an indicator is on or a sound is heard), you can try the software reboot method through a combination of remote buttons. This method emulates the reboot command at the core level of the system and often helps when the graphics shell is getting stuck.
Most Xiaomi and Mi TV models have a combination: press the power switch (red circle) on the remote and hold it for 5-10 seconds. The system menu may appear on the screen asking if you have confirmed the reboot. If the menu appears, select Reboot.
In some cases, especially older versions of firmware, you need to hold the Back and Menu (or OK) buttons at the same time. The exact combination may depend on the model of the remote, the standard Bluetooth or IR version. If the remote does not respond, try removing the batteries from it for 10 seconds and inserting them back to reset the connection.
There is also a method of “cold” reboot via the remote, which helps to reset the suspended module Wi-Fi or Bluetooth:
- 🔄 Press and hold the Home and Back button at the same time for 10 seconds.
- 🔋 Or press the power button on the remote before the Mi logo appears on the screen.
- 📡 To reset the network: go to settings and turn off Wi-Fi before restarting.
If none of the combinations work and the TV continues to hang on the screensaver, move on to the physical method of power outage described below.
Hardware Reset (Hard Reset)
When the software methods are powerless and the screen is black and the TV is not responding to the remote, the only proven option is a complete power reset, a process that allows the residual voltage in the motherboard capacitors to be discharged and all processes, including the system demons, to be forcibly stopped.
To do this, you need to physically disconnect the TV from the power grid. Just pressing the switch on the case or remote control is not enough, because the power supply continues to give off the duty voltage.
⚠️ Warning: Before power is turned off, make sure that the TV does not update the firmware (the indicator does not blink and it does not say "Update in progress".
The optimal latency is 2 to 5 minutes, during which time the capacitors will be completely discharged and the RAM will be cleared. While the TV is off, you can also press and hold the power button on the device itself (if any) for 15 seconds to ensure that the residual charge is removed.
After a pause, plug the TV into the socket. Don't use the remote to turn on -- press the physical button on the case or at the end of the panel. It may take longer than usual to load, as the system will be checking the file system.
Reset to factory settings via menu
If a conventional reboot doesn’t fix persistent lags, app bugs, or network connectivity issues, a more radical step may be needed – a Factory Reset – which removes all user data, installed apps, Google accounts, and network settings, returning the TV to the “out of the box” state.
To perform the reset, go to Settings → General (or Additional) → About TV. Find Reset or Factory Reset. The system will warn you that all data will be deleted. Confirm the action by entering a PIN if it was installed, or simply agreeing to the terms.
The reset process takes 5 to 15 minutes depending on the amount of internal memory and recording speed, the TV will turn off and on several times, and once completed, you will need to reconfigure the language, Wi-Fi and log in to your Google account.
| Type of discharge | Data retention | Implementation time | When to use |
|---|---|---|---|
| Software reboot | All data is stored. | 1-2 minutes | Small interface lags |
| Nutrition | All data is stored. | 3-5 minutes | With the system completely frozen. |
| Factory Reset | Data is deleted | 10-20 minutes. | Critical errors of the OS |
It is recommended to regularly back up important settings or app lists if this feature is supported by your Google account, so that after a reset, you quickly restore the familiar environment.
Using the Engineering Menu for Diagnostics
For advanced users and professionals, there is a way to reboot and diagnose through the engineering menu, a hidden part of the system that allows you to access technical parameters, check the matrix, sound and perform a deep reset, and log in to this menu through special combinations of remote buttons.
One common way to log in on Xiaomi TVs is to go to Settings → About TV and quickly tap 7-10 times on MIUI Version or Build Number. The window that opens may require you to enter code. Standard codes often vary, but 6688 or 1234 is popular.
In the engineering menu, navigation can only be done by volume and OK. Find the Common or Factory section, then select Factory Reset or Reboot. Be extremely careful: changing unknown parameters in this menu can lead to incorrect color or sound performance.
- 🛠️ Selftest: partition for testing components (screen, sound, remote control).
- 📡 Network: settings MAC-addresses and Wi-Fi module.
- 🔄 Upgrade: Update of firmware with USB net.
If you accidentally changed the setting in the engineering menu and the TV is acting strangely, the only way out is often a complete reset via Factory Reset in the same menu or flashing the device.
Resolve problems if the TV is not turned on
A situation where the Xiaomi 4K TV does not respond to the on button, the indicator does not burn and the screen is black, may indicate a failure in the power supply or a freeze of the control controller. Before looking for a soldering iron, try the "discharge" method.
Turn off the TV. Find a physical power button on the body (usually behind, side or bottom) and hold it for 30 to 60 seconds without letting go. Then, as you keep holding the button, plug the TV into the power outlet. Release the button only 10 seconds after signs of life appear.
This method often helps to "rock" the power supply, if it is gone in defense, and it is also worth checking the power outlet itself and the power cable - sometimes the problem is trivial and lies in poor contact of the fork or broken wire.
⚠️ Warning: If after all the manipulations, the indicator flashes red or green in a certain rhythm, this is an error signal from the self-diagnostic system.
In rare cases, the problem lies in the remote. Try to control the TV through the Mi Remote app on your smartphone (if the phone has an IR port) or connect a regular one. USB-If you call the menu from the keyboard, it means there's a problem with the IR receiver or Bluetooth TV module.
Prevention of freezes and optimization of the system
To avoid rebooting, you should follow simple rules for using a smart TV: Android TV is demanding on the space and quality of the network connection, and filled memory is the main reason for the brakes.
Remove unused applications regularly. Go to Settings → Apps and see what takes up the most space. Cache data can be cleared through the settings of each application or using built-in cleaning utilities, if you have them in your version of MIUI.
Turn off automatic app updates at night if the TV is used as a background screen or to listen to music. background downloads can load the processor and cause image twitching. It's also a good idea to turn off unused features like Bluetooth if you're not plugging in headphones or gamepads.
Use only proven sources for installation APK-Third-party launchers and “accelerators” often contain ads and malicious code that mines cryptocurrencies in the background, overheating the device. Xiaomi’s original shell is already optimized for hardware, and third-party improvements often backfire.
