Modern Xiaomi TVs running Android TV or Google TV are powerful multimedia centers, but the basic feature of watching TV for many users remains a priority. The process of initial channel installation often seems confusing due to the features of the MIUI for TV interface, which is significantly different from the usual menus of other manufacturers. It is important to determine the type of connection, as this will depend on the further algorithm of actions and the choice of signal source.
Device owners often face a situation where automatic search does not give results or gives an error "no signal" when the antenna is connected. This can be due to the wrong choice of region, outdated software or incorrect frequency settings. In this article, we will discuss all the stages of setting up in detail so that you can enjoy your favorite transmissions in high quality without unnecessary complexity and technical failures.
Preparation of equipment and verification of connections
Before you go to software settings, you need to make sure the physical integrity of the connections.The antenna cable should be tightly inserted into the corresponding connector on the back or side of the TV, marked as Antenna In or RF In. If you use a room antenna with an amplifier, make sure that it is connected to the power source, as the passive receiver may not cope with the signal level in urban conditions.
For owners of digital television (receivers) DVB-T2) The situation is different: the antenna cable connects directly to the console, and the TV acts only as a monitor, in which case the search for channels is done through the menu of the console itself using its remote, and not through the settings of the Xiaomi Mi. TV. Switching between sources is done by the Input button or selecting the appropriate one. HDMI-port.
⚠️ Note: If you use an active antenna (amplifier) but have not connected it to an outlet or USB-The TV can show the absence of channels, as the signal level will be critically low.
The quality of the cable also plays a crucial role: old Soviet single-layer cables may not provide stable digital flow transmission, especially over long distances from the repeater. It is recommended to use a double-shielded coaxial cable and a copper vein to minimize interference. Check if there are severe inflections or insulation damages on the cable that can lead to data loss.
Configuring digital TV DVB-T2
The main broadcast standard in Russia and many CIS countries is DVB-T2. To receive it, the built-in tuner of the Xiaomi TV must be properly configured to work with this format. The process begins with the entrance to the main settings menu, where you need to find the section responsible for the channels. Depending on the firmware version, this item can be called Channels, Broadcast or located inside the All settings category.
When you start the automatic search, the system will suggest you choose the connection type, and it's critical to choose the antenna or Ether option, not "Cable" or "Satellite" if you don't have the appropriate equipment. After you select the source, the TV will suggest you reconfigure the list of channels, agree and start the scan, at which time the device will consistently check all available frequencies.
☑️ Checklist before searching for channels
If the automatic search is complete, but the channels are few or disappear periodically, you should use manual adjustment. This requires knowing the frequency of the nearest transmitter, which can be found on official resources of digital television operators. The manual setting menu enters the channel number or frequency, and the system evaluates the signal level and quality in real time, allowing you to accurately position the antenna.

Satellite and cable TV setup
Owners of Xiaomi TVs with support for the DVB-S2 standard can connect the satellite antenna directly, without using an external receiver. To do this, the cable from the satellite dish converter is connected to the Sat In connector. However, it is worth remembering that not all Xiaomi TV models have a built-in satellite tuner, so first check the specification of your model or check for the appropriate connector on the case.
For cable TV, which is broadcast by coaxial cable providers, the DVB-C standard is used. When choosing a cable connection type, the TV will ask you to select an operator from the list or search for frequencies manually. If your provider is not on the list, choose Others or Full Scan so that the device finds all available transponders on the network.
| Signal type | Standard | Equipment required | Tv connector |
|---|---|---|---|
| Etheric digital | DVB-T2 | Decimeter antenna | Antenna / RF In |
| Digital cable | DVB-C | Provider cable | Antenna / RF In |
| Satellite. | DVB-S2 | Satellite dish | Sat In (if any) |
| Analog | DVB-T / PAL | Antenna (obsolete) | Antenna / RF In |
It is important to note that many modern providers are moving to IP-TV that is transmitted via Internet cable or Wi-Fi, in which case the setting through the antenna input is not possible. You will need to install your operator's application from the Google Play Store on the TV or configure it. IPTV via a third-party player, which we will discuss in the following sections.
Using applications to view IPTV
With the rise of Internet technology, traditional antenna channel search is becoming a thing of the past, giving way to IPTV. Xiaomi Android-based TVs allow you to install specialized applications such as Lampa, Peers.TV, Vintera TV or universal players like Televizor and OTT Navigator, which provide access to hundreds of channels in high resolution without binding to the antenna.
These applications require stable network access if the built-in Wi-Fi module is not enough to transmit heavy video streams to the Internet. 4K, recommended LAN-adapter connected through USB, or adjust the static IP-Address to exclude buffering. Applications are installed through the Google Play store or by downloading APK-flash-drive.
⚠️ Note: When using free of charge IPTV-Playlists are often unstable and can stop working at any time. For stable viewing, it is recommended to subscribe to trusted service providers.
Setting up IPTV It usually takes a few minutes. Once you install the app, you need to type in. URL-playlist address (format reference.m3u), Some applications, like Lampa, have their own channel base and do not require complex settings, working on the principle of an online cinema.
💡
Use an Ethernet cable instead of Wi-Fi to watch IPTV in 4K. A wireless connection often doesn’t provide the stable speed needed for high-bitrate video streaming, resulting in squares on the screen and stops.
Solving problems with signal search and quality
When Xiaomi TV does not find channels, it can be caused by a software failure, in which case it helps to completely reset the tuner settings or update the operating system to the latest version. Go to Settings → About TV → System Update and check for new versions of the software, as Xiaomi engineers regularly release patches that improve compatibility with various types of signals.
Another common problem is time and date desynchronization, which can affect some digital services and transmission schedules (EPGs). Make sure that the system settings automatically determine the time over the network. If channels are found, but the image is "split" into squares, this is a sure sign of weak signal or interference in the cable.
To diagnose the signal level, you can use the engineering menu or special applications from the Play Market, which show the real signal power in dBm. If the level is below -80 dBm, a stable picture is impossible, and you need to replace the antenna, amplifier or redirect the receiver towards the tower.
💡
Image quality is directly dependent on the signal level, not the diagonal of the TV. A weak signal on a 4K TV will look worse than on an old kinescope model, since compression artifacts are more visible on larger screens.
