Modern smart TVs, such as Xiaomi models, have complex Android TV logic that often baffles new users. When talking about turning on the screen, it usually means not just powering the display from deep sleep, setting up a screensaver, or even using the TV as a smartwatch on the wall. Standard device behavior involves automatically turning on when the signal is given, but use cases vary.
In this article, we'll explore not only the banal on the remote, but also the subtle settings of MIUI for TV that allow you to control the behavior of the screen in standby mode. You'll learn how to make the display show information when the TV is formally turned off, and what to do if the screen is turned off and does not respond to commands. Understanding these processes will help you to fully harness the potential of your technology.
Often users confuse power saving mode with complete malfunction, so it is important to distinguish between software settings and hardware problems. We will look at standard activation methods, hidden functions and diagnostic methods if standard paths do not work. This guide covers most popular models, including the Mi TV Stick series, Mi Box and full-fledged TVs with diagonals from 32 to 75 inches.
Basics of nutrition management and sleep regimen
The first thing the owner faces is the difference between turning off and going to sleep.In the Android TV operating system on which Xiaomi TVs are based, the power button on the remote most often sends the device to standby rather than turning it off completely from the network.The screen goes out, the indicator can flash or burn with even light, but the system continues background processes, such as downloading updates or waiting for a voice command.
To wake up the screen, usually a short press on the center button with the image of a circle and a crossed line is enough. If the TV is connected to the smart home or configured accordingly, the screen can turn on automatically when a signal arrives from the Chromecast or when an application is launched on a smartphone. However, if the device is in deep sleep, physical interaction with the remote control is required.
There's also a nuance about the sleep timer, which is that if you set a menu viewing time limit, the TV will force the screen to go out at the end of the set time, and in this case, it's the standard way to turn it back on, but you have to reset the timer separately if you're going to watch the content further, and the system warns you to shut it down, but in a hurry, it's easy to skip.
⚠️ Warning: If the indicator on the TV body flashes red or orange when trying to turn on, it may indicate a critical system error or power supply problem, rather than just a sleep pattern.
To completely turn off, when the screen is guaranteed to go out and stop consuming power, you need to hold the power button on the remote for a few seconds before the menu appears, and select "Switch off." In this state, the screen can only be turned on by re-pressing the power button, automatic signals from the phone may not wake the device instantly.
Function "Screen screensaver" and clock mode
One of the most popular features for those who want to “turn on the screen” without watching videos is the screensaver mode. Xiaomi TVs support the Ambient Mode feature (or its analogues depending on the region), which turns a black rectangle into an interior element.
To activate this feature, you need to go to the system settings. The path usually looks like: Settings → Device → Screensaver. Here you can choose the source of images: Google Photos, embedded themes or Art Gallery. Once you set up and select the time to transition to this mode, the TV will automatically turn on the screen with the selected content when you are not watching television.
Importantly, to function, the TV must remain connected to the grid and not be completely de-energized through a button on the case (if any) or by pulling the plug.The system itself adjusts the brightness and frame intervals to prevent the matrix from burning out, especially if you have an OLED model.
Some users want to use the TV as a wall clock all the time, and you need to select the "Clock" style in the settings of the screensaver and set the timer for the transition to this mode to a minimum value or "immediately." However, it is worth remembering the resource of the panel: a constant static image can lead to uneven wear of the pixels over time.
💡
To extend the life of the matrix in the clock mode, set the interval of the image change or enable the function of moving the image, if it is available in your firmware version.
Setting up the alarm clock and schedule of switching on
Xiaomi TVs have a feature that allows you to turn on the screen on a schedule, which is convenient for those who like to wake up to the news or want to have a screen with a greeting in the living room by the time guests arrive, called "Alarm" or "Timer Turn on" and is in the system settings section.
To set up, you need to go to the Settings menu → The device → Preferences → Alarm clock. You can set a specific time and date, and you can also select the source of the signal. This can be an embedded TV application, run a specific specific TV. HDMI-If you save the settings, the TV will automatically exit the standby mode at the appointed time.
- 🕒 Daily alarm: The screen will be on at the same time every day, which is useful for creating a mode of the day.
- 📅 Single-on: Perfect for situations where you need to turn on the TV in your absence to showcase content.
- 🔊 Audio: You can adjust whether the turn on will be accompanied by sound or the TV will turn on in quiet mode.
Keep in mind that the TV must have the current time and date settings to operate the alarm clock. If the device is not connected to the Internet or has a time knock, automatic activation may not work or occur at the wrong time.
⚠️ Warning: The alarm function will not work if the TV is completely off (pulled out of the socket) or if the child protection blocking the control is triggered.
The problem of black screen with working sound
When there is sound, the channels are switching, but the screen is black, it is a common problem, and this can be caused by a malfunction of the backlight or a software freeze of the module responsible for the output of the image, in which case it is said that the TV is "on, but the screen is not on."
The first step is to check the backlights, turn on the TV and point the smartphone flashlight close to the screen, and if you see a dim image of a menu or picture, it means that the matrix is working, but it is burned or not receiving power. LED-It's a hardware malfunction that requires a service center to intervene.
If you have no flashlight at all, but you have sound, the problem is that you have to crash Android software, and in this case, you have to force the reboot, you have to pull the TV plug out of the socket, you have to wait 1-2 minutes until the capacitors are completely discharged, and you turn it back on again, and this action releases the static voltage and often returns the image.
☑️ Diagnostics of the black screen
If you use a console or game console, make sure that the correct signal source is selected (HDMI 1, HDMI 2). Sometimes the TV is formally on, but shows a black screen because there is no signal at the active input and automatic source determination is disabled.
Remote control and inclusion from a smartphone
Xiaomi's ecosystem allows you to control your TV remotely, which includes a screen-on feature, which uses the Mi Home app or Google Home app, depending on how the device is configured, which is especially true if the remote is lost or malfunctioned.
To control the screen, both devices must be on the same Wi-Fi network. In the Mi Home app, after adding the TV to the list of devices, a power button appears in the control interface, pressing it sends a data packet (Wake-on-LAN or similar protocol) that brings the TV out of sleep mode.
You can also activate the screen through voice assistants. If you have a column with Google Assistant or Alice (if you have integration), you can say "Put the TV on in the living room." The system will send the command to the TV, and the screen will light up. To work this feature, the "Mobile Control" or "Remote Start" option must be activated in the TV settings.
Critically, for remote switching on, the TV must be connected to Wi-Fi and be in standby mode, rather than completely shutting down (unless the model supports Wake-on-LAN at the hardware level).
Why is remote inclusion not working?
Table of codes and button combinations for management
For advanced users and those using universal remotes, information on standard pairings will be useful. Although Xiaomi uses the standard Bluetooth and IR protocol, knowing the basic commands helps in setting up universal remotes.
| Action. | Main button | Alternative (Remote) | Commentary |
|---|---|---|---|
| Turning on/off | Power (Red Circle) | 3 sec. | Short press – sleep, long – off menu |
| Screen activation (from sleep) | Any button | Voice search | Pressing any button will wake up the Bluetooth remote |
| Shifting source | Input / Source | Menu button | Switches HDMI/AV inputs |
| Resetting the system | - | Loudness - + Nutrition | Only when downloaded (Recovery) |
Using universal remotes requires the code to be configured correctly. In most cases, the code for Xiaomi is in the 0220-0230 range, but it is better to use the autosearch feature offered by most modern universal remotes. This ensures that all functions, including screen wake-up, will work correctly.
Resetting and system restoration
If the screen doesn’t turn on, goes off immediately after the logo is loaded, or behaves inadequately, it may be necessary to reset the settings to factory settings.This is a radical measure that removes all user data, accounts and installed applications, returning the TV to the “out of the box” state.
You can reset through the menu if the screen responds at all: Settings → Device → About System → Reset. If the menu is not available, the hardware method is used. The back of the TV (often near ports or on the side edge) may have a hidden Reset button or a combination of buttons on the body itself (not the remote) that you need to pinch when power is turned on.
💡
Resetting to factory settings eliminates 90% of the software errors associated with the interface freeze and screen failure, but requires reconfiguration of all channels and applications.
After reset, the TV will start in initial settings, the screen will be on continuously until the setup wizard is complete, and don't interrupt this process, as it is critical for calibrating the display and installing current system drivers.
