Modern Xiaomi Smart TVs, such as the Mi TV 4S, offer users a wide range of entertainment options, but basic setup of terrestrial TV reception is often difficult. Many owners, when they first encounter the Android TV operating system interface, can not immediately find the usual frequency scanning functions.
To correctly display all available broadcasts, you need to choose the right signal source and antenna input type. In the Xiaomi Mi TV 4S model, a built-in DVB-T2 tuner that supports digital broadcast standards is responsible for this. Before you start setting up, make sure that the antenna cable is tightly inserted into the appropriate socket on the back of the device, otherwise the search process will be unsuccessful.
In this article, we will take a detailed look at all the configuration steps so you can enjoy quality images without delay, we will look at both automatic search and manual frequency adjustment for complex reception cases, and we will also discuss the issues of connecting cable providers and satellite equipment through an external receiver.
Preparation of equipment and inspection of connections
The first and most important step is to physically connect the antenna. On the back of the Xiaomi Mi TV 4S, you need to find a connector signed as Antenna In or having the appropriate icon. This is where the coaxial cable that comes from the indoor or external antenna connects. If you plan to watch cable TV, the connection is similar, but the signal comes from the provider.
The quality of the image depends on the condition of the cable and antenna. If the signal is weak, the TV may show a picture of artifacts or not find channels at all. In such cases, it is recommended to check the integrity of the plug and the absence of inflections on the wire. To reliably receive the digital signal, the level must be stable, which is especially important in remote areas from TV towers.
⚠️ Warning: Don't try to connect a satellite antenna (plate) directly to the Antenna In connector without using an external receiver. - Xiaomi Mi TV TV 4S It does not have a built-in satellite tuner DVB-S2, And direct connection will not work.
After you have a physical connection, you need to turn on the TV and wait for the operating system to fully load, and you should only switch to software settings when the Android TV desktop with available applications appears on the screen, which ensures that all system services responsible for the tuner are already running and ready to go.
⚠️ Note: If you are using an active antenna (amplifier), make sure it is connected to a power source. USB, This is why a free port on the TV is required for this.
Automatic setup of digital channels
The easiest way to find all the programs available is to use the auto-search function. To do this, go to the main menu and select the gear icon that opens Settings. In the list of options that opens, you need to find the channel section, which in different versions of the firmware can be called Channels or located inside the System menu.
Within the channel settings menu, select Channel Search or AutoSearch. The system will suggest you choose the signal type: antenna, cable or satellite. For standard broadcast, select the antenna (DVB-T/T2). If you are connected to a cable network of a provider that does not encrypt the signal, choose the cable (DVB-C).
☑️ Checking before launching the search
When the scanning process is started, a progress scale will appear on the screen, during which time the TV will consistently check all frequencies in the range, the process can take from 3 to 10 minutes depending on the number of transponders found, and it is not recommended to interrupt the search, since the list of channels may remain incomplete.
When the scan is complete, the system will notify you of the number of channels and radio stations found, and you can now switch between them using a remote control, and if fewer than 10 channels are found in your area, you may need to manually adjust the antenna or choose another type of scan.
What to do if you find 0 channels?
Manual frequency setting and list editing
In situations where automatic mode cannot find a particular channel packet, manual setting is used. To do this, select the Manual Search option from the channel search menu. Here you will need to enter a specific frequency (in MHz) or channel number that broadcasts the desired program. This information can be found on the website of your regional digital television operator.
Manual mode is also useful for sorting a list. Once you've finished scanning, you can move your favorite channels to the top of the list or delete the ones you don't want to. To do this, select Editing from the channel menu, tick the right positions, and do the action you want, which makes navigation much easier if you only use a few stations.
It's important to note that manual adjustment requires precision, that even if you make a mistake in one frequency sign, you can't decode the signal, and you can use the remote to input the numbers carefully, checking each value, and if you have a signal, you can see the percentage of the quality and strength of the signal on the screen.
⚠️ Note: When manually configuring cable TV (DVB-C) You often need to specify additional parameters, such as the flow rate (Symbol Rate) and the type of modulation. This data is provided by your provider, without which you can not adjust.
Setup IPTV and Third Party Applications
Owners of Xiaomi Mi TVs TV 4S They have the unique ability to watch television over the Internet using technology. IPTV. This allows you to broadcast hundreds of channels in high quality without depending on the antenna signal, OTT Player, Peers.TV or Lazy IPTV.

Solution: no signal or channels missing
One of the common problems is the sudden disappearance of channels or the message "No signal" and the first thing to check is whether there is a preventive work on the TV tower in your area, if the equipment of the provider is all right, the problem may be a software failure of the TV.
Try reconfiguring the channels by turning off the antenna and turning it on again. It is also an effective method to reset the tuner to factory values. In some cases, updating the TV system software helps, as new firmware versions contain patches to work with frequency ranges.
Below is a table with the main causes of problems and ways to solve them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Black screen when switching | Weak antenna signal | Check the connection, turn the antenna |
| Sound's there, no image. | Decoding error | Reboot the TV, update the software |
| He doesn't find a channel. | Incorrect region or signal type | Check country and source settings (DVB-T2) |
| The picture is falling into blocks. | Interference in cable | Replace the antenna cable or plug |
If neither method worked, the tuner in the TV or the antenna equipment might have malfunctioned, and then you could connect the TV to another, known, working antenna for the diagnosis, so you could pinpoint the source of the malfunction.
Use of external tuners and receivers
If the built-in functionality of Xiaomi Mi TV 4S is not enough, for example, to watch satellite TV, external consoles are used. The receiver connects to the TV through an HDMI connector, which provides video and sound transmission in high resolution, in this case the TV acts only as a monitor.
To operate such a system, you'll likely need two remotes: one from a TV to adjust volume and brightness, and one from a channel-switching console, but many modern receivers support HDMI-CEC, allowing both devices to be controlled by one remote control.
💡
The external receiver is the only solution for watching satellite TV on Xiaomi TV 4S, as there is no built-in DVB-S2 module in this model.
The external device is set up through the console menu itself, not through the settings of the TV. You only need to select the appropriate signal source (HDMI 1, HDMI 2, etc.) from the Mi TV input menu. After that, the image from the console will appear on the screen, and further configuration of the channels is carried out according to the instructions to the receiver.
