Modern TVs Xiaomi Mi TV 4S with a screen diagonal of 55 inches are complex multimedia centers running the Android TV operating system. To control such a device through buttons on the body is physically inconvenient, and often impossible without prior settings, so the correct operation of remote control is critical for comfortable use.
In most cases, the process of synchronizing the controller with the receiver occurs automatically immediately after the extraction of the batteries, however, the specifics of wireless protocols sometimes require manual user intervention.
In this guide, we’ll take a closer look at all the connection steps, from basic battery installation to complex Bluetooth module reset scenarios, so you can quickly regain control of your TV.
Preparation of equipment and installation of power supplies
The first step before any electronics manipulation is to provide a stable power source. The remote controls for the Mi TV 4S 55 are most often powered by two standard AAA batteries, although modifications that require CR2032-type batteries to save Bluetooth settings are common.
Open the battery compartment on the back of the device, taking care not to damage the plastic latches of the case. Insert new batteries, strictly observing the polarity indicated inside the compartments "+" and "-".
⚠️ Note: Using old or partially discharged batteries can cause a Bluetooth channel to malfunction, even if the infrared port is functioning correctly.
After the power is installed, pay attention to the LED indicator located at the top of the remote, which should light up briefly when pressing any button, indicating that there is a voltage in the circuit.
If the indicator does not light up, try to slightly twist the batteries in the socket or wipe the contacts with a dry cloth, as oxidation can prevent the passage of current.
Automatic pairing on first activation
Modern Xiaomi TVs are equipped with an automatic peripheral detection module. When you first turn on the TV or after resetting to the factory settings, the system goes into standby mode for the remote connection.
Point the remote towards the bottom of the TV where the signal receiver is located, and simultaneously press two buttons: the central confirmation button (often designated as OK or Enter) and the back button (denoted by the arrow or Back symbol).
☑️ Verification of primary connection
Hold these buttons for 5-7 seconds until a message about successful pairing appears on the TV screen, at which point the TV's Bluetooth module scans the airwaves and captures the signal from the remote.
It is important to perform this procedure at a distance of no more than 20-30 centimeters from the screen, since the signal power may be limited by software for safety when initially set up.
If a notification appears on the screen, release the buttons and check the navigation on the menu. In some cases, the system may request confirmation of action by pressing the OK button.
Manual settings through the Android TV menu
In situations where automatic detection fails, you need to perform forced synchronization through the system menu, which requires either a working remote (if the problem is only with Bluetooth functions) or a regular connection. USB-keyboards or mice to the TV port.
Go to the main menu of the system and select the settings section, which is usually indicated by the gear in the upper right corner of the screen. You need to find the Settings item, then go to the Remote and Accessories or Bluetooth section.
In the list of available devices, click on the button "Add Accessory" or "Search for devices." The TV will go into active scanning mode.
Again, press the combination of OK and Back buttons on the remote you want to connect. The device should appear on the list of detected gadgets called Mi Remote or similar.
Select the device you find from the list to complete the mating procedure, and then the remote will be attached to the TV and will be activated each time you turn on.
Using an infrared port for basic control
Many users are unaware that the remotes for the Mi TV 4S 55 are often hybrid in design, and in addition to Bluetooth, which is necessary for voice control and working through applications, they are equipped with a classic infrared port (IR).
The IR signal allows you to control basic TV functions such as on/off, volume control, and switching signal sources even if the Bluetooth pairing is broken or completely absent.
| Signal type | Functions | Distance of action | It requires a pairing. |
|---|---|---|---|
| Bluetooth | Voice, navigation, applications | Up to 10 meters (360°) | Yes. |
| Infrared (IR) | On/off, volume, inputs | Up to 5 metres (direct visibility) | No. |
To work the IR part does not need to perform any complex settings, just the presence of batteries and line of sight between the remote and the receiver on the TV.
This is especially useful in cases where a software glitch is blocking Bluetooth, but you urgently need to turn off the TV or turn the volume on.
💡
If Bluetooth doesn’t work, use the IR port to log in to the menu and perform a reset, after which Bluetooth is usually restored.
Solving Connection Problems and Resetting Settings
If none of the above methods worked, it is possible that the Bluetooth module has accumulated errors or there is a conflict of addresses, in which case a complete reset of the remote is required.
Remove the batteries from the remote. Then press and hold any button on the remote for 10-15 seconds (no batteries) to discharge the residual voltage in the capacitors.
Put the batteries back in and immediately, without letting the remote go to sleep, hold it close to the Mi logo on the TV. Press the Home and Back buttons for 10 seconds at the same time.
⚠️ Warning: When performing a reset, make sure that the system update process is not started on the TV, as loss of control at this point can lead to software errors.
After this procedure, the TV should detect the remote as a new device, and if the problem persists, check if there are too many Bluetooth devices connected to the TV, and remove the extra ones from the settings menu.

Alternative management methods: smartphone and USB
In case of a complete failure of the regular remote, you can use your smartphone as a full replacement. Android TV operating system installed on Xiaomi Mi TV 4S supports Wi-Fi control.
Install the official Mi Remote app (for Xiaomi phones) or Google Home/Android TV Remote Control (for other Android and iOS devices).
The app will scan the network, find your Mi TV 4S 55 and prompt you to enter a confirmation code that will appear on the TV screen, after which the smartphone screen will become a touchpad with full functionality.
