Modern Xiaomi TVs with Android TV offer a wide range of features, but the first thing that is required of any user after unpacking is to set up the TV broadcast. Whether you connect an active room antenna in your apartment or a satellite receiver in your private home, the basic process of finding channels remains similar, although it has its nuances in the MIUI TV menu. The correct initial setup guarantees a stable high-quality image without compression artifacts.
Device owners often face confusion between DVB-T2 digital terrestrial TV and DVB-C cable, which leads to a lack of signal when the source is not chosen correctly. The interface of Mi TVs may vary depending on regional firmware (Global, Indian, Russian), but the logic of the tuner is the same. It is important to understand that you do not need the Internet to receive the signal, just a properly connected coaxial cable.
In this guide, we will take a detailed look at the entire journey from connecting antenna cables to sorting your favorite channels, look at common errors such as missing a signal due to poor contact or incorrect frequency range, and focus on fine-tuning the image, as factory settings are often too bright or cold for comfortable viewing.
Preparation of equipment and inspection of connections
Before you get to software settings, you need to make sure the physical integrity of connections. Digital TV signal is very sensitive to the quality of contacts, so using cheap adapters or damaged cables often causes intermittent images. Make sure that the antenna cable is tightly inserted into the ANT IN or RF IN connector on the back of the Xiaomi TV.
If you use an amplifier indoor antenna, check if it's powered. Many modern antenna models require a separate antenna. USB-If you use a collective antenna in an apartment building, make sure that the signal reaches your outlet by checking it on another receiver if possible.
⚠️ Warning: Never connect the satellite receiver cable directly to the TV antenna input unless the receiver is set to mode. RF-- The modulator. 12-19From active satellite dish to the entrance of the air tuner DVB-T2/C It can put the TV’s tuner module out of action.
For owners of private homes using satellite television, the setting is made exclusively through an external receiver (set-top box), and not through the built-in tuner. In this case, the TV acts only as a monitor, and the channels should be searched in the menu of the console itself, switching to the set-top box. HDMI-Xiaomi’s built-in tuner is designed for broadcasting only on-air (antenna in the window) or cable (wire from the provider in the wall.
Initial setting and region selection
When you first turn on a new TV or reset to Factory Reset, the system will suggest you go through the initial configuration. The critical step is choosing the country and language. The selected country determines the list of available frequency plans and the order of sorting channels. If you are in Russia, but choose Global or another region, the numbering may be lost, and some frequencies will not be scanned.
While the system may request a connection to a Wi-Fi network during the setup process, although the Internet is not required for digital TV to work, it will allow the TV to automatically download current broadcast data and update the EPG database. Without the Internet, channel names can be displayed simply as Channel 1, Channel 2, and so on.
Special attention should be paid to the choice of connection type. In the initial setting menu, the question often is: "How do you connect to the TV?". You need to choose the Antenna or Cable option, but not Satellite, if you do not use a special CI+ module. Choosing the wrong source at this stage will result in a scan going to waste and the list of channels will remain empty.
💡
If you made the wrong country choice when you first set up, don't panic. You can change the region under Settings → General → Region, but you may need to reinstall applications or re-search channels after that.
Automatic search for digital channels
The easiest and most reliable way to set up a TV on Xiaomi TV is to use automatic search, which allows the system to go through all frequencies on its own and save the streams found. To start the process, go to the main menu and find the Settings section (the gear icon in the upper right corner).
The navigation menu that opens may vary depending on the shell version. You need to find the channel item. Usually the path is: Channels → All channels → Channels → Channel Search. In some versions of the firmware, this section is hidden inside Settings → Broadcast or Etheric TV.
When you run the scan, you'll see the progress bar. It can take 2 to 10 minutes depending on the number of multiplayers available and the signal power. At this time, the TV will consistently check the frequencies. If the signal is weak, the process may be slower. It is not recommended to interrupt the search, as this can lead to incorrect recording of frequencies in the device's memory.
☑️ Checklist before searching
Once the scan is complete, the system will report the number of TV and radio channels found, and if less than 10-12 channels are found (the standard for the first multiplex in the Russian Federation), then either the antenna is not working well or the wrong type of search is chosen (for example, analog instead of digital).
Manual tuning and working with frequencies
In situations where automatic search does not work or not find all channels, manual adjustment is necessary, especially in remote areas where repeaters operate at non-standard frequencies, or when using cable providers that do not follow conventional frequency grids.
To switch to manual mode in the channel search menu, select Manual Scan. Here you will need to enter specific parameters: frequency (in MHz) or channel number (TV Channel). For digital broadcasting in Russia, the DVB-T2 standard is used, which broadcasts in the decimeter range (UHF), usually from 300 to 800 MHz.
On the manual setting screen, you'll see a signal quality scale that has two parameters: Level and Quality. Level shows the strength of the electrical signal coming from the antenna, and Quality shows the absence of errors in the digital stream, and your task is to find the frequency where both are maximum.
| Parameter | Description | Normal value. | Problem. |
|---|---|---|---|
| Signal strength | Power of incoming radio signal | 60-90% | Less than 40%: Image loss is possible |
| Signal quality | Signal/noise ratio, no errors | 70-100% | Less than 50%: the picture is broken into cubes |
| BER (Bit Error Rate) | Bit error ratio | Close to 0. | High values lead to artifacts |
⚠️ Note: When manually configuring cable TV (DVB-C) ISPs often require additional parameters such as flow rate (Symbol Rate) and modulation (usually) to be entered. 6.75 MS/s or 7.00 MS/s, modulation QAM). This information can only be found from your provider, it is impossible to guess it.
Setting up image and sound for TV channels
Once channels are found, it often turns out that the picture looks unnatural: too bright, contrasting or with unnatural colors. Factory settings of Xiaomi TVs are often focused on display in the store, not for home viewing. For correction, go to Settings → Image.
The Movie or Standard mode is recommended. Vivid usually distorts colors and makes actors' faces look unnaturally red. It is also worth disabling various image "improvements" such as noise reduction or dynamic contrast if you are watching low-quality content, as they may add artifacts.
If you're watching old 4:3 content on a widescreen TV, the image can be stretched. Use the Menu button or a special button on the remote (often marked as a square or arrow) to select zoom mode: 16:9, 4:3, Zoom or Auto. HD-The broadcasting must always be 16:9 or Auto mode.
Secret image settings
Solving typical signal problems
One of the most common problems is the message, "No signal," or the periodic fading of the image with the message, "The signal is too weak." 80 percent of the time, it's physics-related: the antenna cable's inflection, the contact oxidation, or just the direction of the antenna. Try turning the antenna toward the nearest TV tower.
If the TV finds channels but they show with a No data error or black screen when turned on, it is possible that the stream being broadcast is encoded or a custom audio codec is used. Xiaomi's built-in tuner supports the main MPEG-2 and H.264 (AVC) codecs, but may not cope with the new compression formats of some providers.
The problem may also be a software failure of the tuner itself, in which case it helps to clean the data of the Translation application or completely reset channel settings. Remember that after any update to the Android TV firmware, the list of channels can be reset, and the search procedure will have to be repeated.
💡
If the signal quality scale is below 50% even when manually configured, no software methods will help - you need to replace the antenna, amplifier or cable.
