How to set up the remote on the TV Xiaomi Mi TV 4S: all ways + codes

Connecting the remote from Rostelecom to the Xiaomi Mi TV 4S often raises questions among users — especially if it is about replacing the native remote or using a universal device from the provider. Unlike standard Xiaomi remotes, which synchronize automatically over Bluetooth, Rostelecom remotes work on the IR protocol and require manual adjustment. In this article, we will analyze all the current methods of binding, including code search, manual synchronization and solving typical problems from lack of reaction to resetting.

It’s important to consider that the Xiaomi Mi TV 4S (L43M5-5ARU, L50M5-5ARU, etc.) supports most universal remotes, but you need to choose the right manufacturer’s code or use auto-search mode. If you tried to set up the remote and nothing worked out before, it’s probably the problem with the wrong code or conflict of IR signals. We’ve put together all the working combinations for 2026 and added instructions for the rare cases where standard methods don’t work.

Why does the remote not work with Xiaomi TV 4S?

Before setting up, you need to understand the reasons why the remote may not respond to commands, and most often, the problem lies in one of three factors:

• 🔴 Protocol incompatibility: Rostelecom new-model remotes (e.g., models) STB-104 or STB-205) They can use unique IR codes that are not recognized by Xiaomi TVs by default.
• 🔋 Discharged batteries: even if the indicator on the remote is on, the voltage may not be enough to transmit the signal. AAA duracell GP).
• 📶 Interference from other IR devices: If there are other remotes nearby (from the air conditioner, music center), their signals can block the command.

Critical detail: Xiaomi Mi TV 4S based on Android TV 9.0 and later can ignore infrared signals if the settings are turned off DAC mode (digital-to-analog converter). This applies to models with Rostelecom consoles - check if this option is included in the Settings → Sound → Output menu.

If the remote previously worked, but suddenly stopped responding, the cause may be a reset of the TV settings (for example, after a software update) or mechanical damage to the IR transmitter, in which case re-synchronization or diagnosis of the remote with a smartphone will help (we will talk about this in the section on health checks).

Methods of setting the remote by Rostelecom: from simple to complex

There are three main methods of binding the remote by Rostelecom to the Xiaomi Mi TV 4S:

1. Code Search – The TV selects a compatible protocol.
2. Manual code entry – you specify the manufacturer’s code from the list.
3. Training remote – copying signals from the native Xiaomi remote (does not work on all models by Rostelecom).

So, the most reliable way to start is manual code entry, which works 90 percent of the time if the remote supports Xiaomi.

Manually configure with codes for Xiaomi Mi TV 4S

For manual synchronization, you will need the manufacturer's code. Below is the current list of codes for Xiaomi Mi TV 4S (checked on firmware 2023-2026):

To enter the code:

1. Turn on the Xiaomi Mi TV 4S and point the remote to it Rostelecom.
2. Press the TV and OK buttons on the Rostelecom remote at the same time until the red indicator lights up (usually 3-5 seconds).
3. Enter one of the codes from the table (e.g. 0178) with the digital buttons. Once the last digit is entered, the indicator should go out.
4. Check the remote by pressing Up/Down or Volume. If there is no reaction, repeat the procedure with another code.

Make sure the TV is on | Check the batteries in the remote | Remove obstacles between the remote and TV | Turn off other IR devices in the room-->

If none of the code worked, try an alternative method: enter the 9999 sequence – this will activate autosearch mode (more in the next section). Also make sure you use the original Rostelecom remote, not a fake – some uncertified devices do not support advanced codes.

Auto-search code: if manual input did not help

If manual code entry fails, use the auto-search function, which takes longer (up to 10 minutes) but covers rare TV models.

1. Turn on the Xiaomi Mi TV 4S and point the remote by Rostelecom to the IR receiver (usually located at the bottom of the screen).
2. Press the TV + OK buttons before the indicator flashes (3-5 seconds).
3. Enter the 9999 code and it will start scanning.
4. Press the CH+ button (or Up) every 2 seconds until the TV reacts (e.g., the volume or channel changes).
5. As soon as the TV responds to the command, immediately press OK to save the setting.

If the process is delayed, don't interrupt it, some codes are checked with a delay, the average scan takes 5-7 minutes.

• 🔄 Reboot the TV (pull the plug out of the socket for 30 seconds).
• 📱 Check the remote for performance using the smartphone camera (more on this below).
• 🔧 Update the TV firmware (in the Settings menu) → On TV. → Updating the system).

💡

If the autosearch does not find the code, try manually entering the combination 0000 - this will reset the remote settings to the factory and allow you to start the search again.

How to check if the remote works Rostelecom?

If the TV doesn't respond to commands, first make sure that the problem is in the remote, not in the TV.

1. Turn on the camera on your smartphone and point the IR transmitter to the remote (usually located at the top).
2. Press any button on the remote. If it is working, you will see a purple flicker on the smartphone screen (the IC signal is not visible to the eye, but is fixed by the camera).
3. If there is no flicker, replace the batteries or check the remote on another device (for example, on the console Rostelecom).

⚠️ Note: Some smartphones (such as iPhones or Xiaomi with an IR filter) do not display an IR signal through the camera, IR Tester (available for Android).

If the remote is working but the TV is not responding, the problem may be:

• 🔌 IR port locking: on some Xiaomi Mi models TV 4S The port is closed with a decorative panel, see if there are any obstacles.
• 🛠️ IR damage: If the TV doesn't respond to any remote control, the receiver may have failed, and only the service center will help.
• 📵 Conflict with Bluetooth devices: disable all connected gadgets (earphones, gamepads) and repeat the setting.

Training remote Rostelecom with the original Xiaomi

If your Rostelecom remote supports learning (as indicated in the manual or on the case), you can copy signals from Xiaomi’s native remote. This method works for STB-205 models and some universal remotes.

1. Place both remotes "face to face" at a distance of 2-3 cm from each other.
2. On the Rostelecom remote, press TV + OK until the indicator blinks.
3. Press the button on the remote that you want to program (for example, Volume+).
4. On the original Xiaomi remote, press the same button and hold until the indicator on the Rostelecom remote goes out.
5. Repeat steps 3-4 for all the buttons required.

This method allows you to transfer up to 80% of functions, but has limitations:

• ❌ Voice commands and gestures are not copied.
• ❌ Retention buttons (e.g. Long pressing) OK) They may not work properly.
• ✅ Maintain basic functions: channel switching, volume control, navigation.

⚠️ Note: if after training the remote Rostelecom begins to conflict with the console (for example, simultaneously switches channels to TV and menu Rostelecom), reset its settings by clamping down. TV + Mute for 10 seconds.

Frequent Mistakes and How to Avoid Them

Even when you set it up properly, users are faced with typical problems, and here are the most common ways to solve them:

If none of the methods worked, check:

• 🔄 Update TV firmware: go to Settings → On TV. → Update the system and install the latest patches. In versions older than 2022, there may be compatibility errors with IR remotes.
• 📞 Support by Rostelecom: some remotes (for example, for Interactive TV 2.0 tariffs) require special activation through the personal account.

💡

If the Xiaomi Mi TV 4S does not respond to IR remotes at all, check the settings in the Settings menu → Devices and accessories → Remote control → DAC mode. This setting should be enabled!
