Modern Xiaomi TVs offer users not only access to media, but also a full platform for receiving digital TV. However, after the first turn on the device, many owners face a lack of image on the screen, since the basic broadcast list is empty by default.
The process of scanning the air or cable frequencies can seem complicated only at first glance. the interface of the Android TV or PatchWall operating system has its own logic, different from the old button menus. In this article, we will discuss all the steps in detail so that you can enjoy your favorite transmissions in high resolution without unnecessary complications.
The quality of the signal reception depends on the correct connection of the antenna cable and the type of source chosen. Digital television requires a stable signal, so it is recommended to check the physical connection before starting the software setting. If the cable is damaged or poorly inserted into the connector, software methods will not help restore the broadcast.
Preparation of equipment and signal verification
Before you go to the software settings in the TV menu, you need to make sure that the hardware is working properly. The antenna input on the back or side of the device should be tightly connected to the cable. Often users forget that a decimeter antenna is needed to receive a digital signal in DVB-T2 format, not an old meter antenna.
If you're using a collective antenna in an apartment building, make sure your provider is broadcasting digitally. Analog broadcasting in many regions is already offline, and the TV simply won't be able to find channels without a corresponding console or standard support. If you use a satellite receiver, the TV will work like a monitor, and the setting is done through the receiver's menu, not the TV.
⚠️ Warning: Make sure the antenna cable is free of severe inflections or clamps. Damage to the central vein or shielding braid leads to the complete disappearance of the signal or the appearance of image artifacts ("quaking" of the image).
For residents of private homes, the height and direction of the antenna are critical. Even the most powerful tuner DVB-T2, built into the Xiaomi Mi TV, will not be able to receive the signal if the antenna is directed in the opposite direction from the repeater. Check the signal level in the diagnostic menu before starting a full scan.
💡
Use a copper central cable and double shielding to minimize interference, especially if the cable is longer than 10 meters.
Automatic setup of digital channels
The easiest and fastest way to access television is to use the autosearch function, which allows the system to analyze the entire frequency range and save the available programs, and to start the process, turn on the TV and go to the main menu.
On the remote, click the button with the image of the gear or select Settings in the upper right corner of the screen. In the menu that opens, find the section responsible for inputs and channels. Depending on the version of the MIUI for TV firmware, this item can be called Channels, TV or Logins.
Select the source of the signal. If the antenna is directly connected to the connector on the TV body, select "Antenna" or "On-air TV." If the cable comes from a cable provider, select the appropriate item. After selecting the source, the system will prompt you to start searching. Click "Channel Search" or "AutoTune".
- 📡 The system will start scanning frequencies, displaying the progress bar and the number of programs found.
- 📺 During the search, the TV will briefly show the image of the channel found to check the quality of the TV.
- 💾 After the process is complete, all channels found will be saved to a common list and sorted by number.
The scan time depends on the number of frequencies available and usually takes 3 to 10 minutes. It is not recommended to interrupt this process, as this can cause a failure in the channel database and require repeating the procedure again.
Manual setting and list editing
Automatic search doesn't always give you the perfect result: some channels may be missing and others may be of poor quality, and in such cases, manual adjustment comes to the rescue, allowing you to check a specific frequency and estimate the signal level without waiting for a full scan.
To enter manual settings, select Manual Search or similar from the menu, and you will see a frequency window, you can change the values manually, or use navigation buttons to sensing the available frequencies, and the real-time display of Level and Quality scales.
If the scales are full and the image is clear, click Save or Add to write the channel to memory, a technique that is particularly useful for finding weak signals that the automation may have missed or for tuning channels of a particular multiplex.
Menu → Settings → Channels → Manual Search → Frequency Selection → SaveOnce you've finished your search, you often need to edit your list, move your favorite channels to the first positions, hide unwanted ones, or delete those that have stopped broadcasting, and select "Edit" or "Manage channels" from the channel menu.
☑️ Signal quality check
Satellite TV setup
Owners of Xiaomi TVs with built-in satellite tuner (DVB-S2) They can connect the signal directly from the satellite antenna, bypassing the external receiver, which makes it easier to control, because you only need one remote control to switch the channels (CAM-module) with operator card, if channels are encoded.
Connect the cable from the satellite dish to the corresponding connector on the TV (usually marked as LNB In) Insert CAM-slot-model CI+, Which is often on the side or back. After you turn on the TV, go to the channel settings and select the source "Satellite».
Run automatic search. Unlike on-air TV, it's important to choose the right satellite to which your antenna is directed (e.g. Eutelsat 36A/36B or Tricolor), if you pick the wrong satellite, the search won't work, even if you're perfectly connected.
| Parameter | Description | Where to find out. |
|---|---|---|
| Frequency (Frequency) | Operating frequency of the transponder | Operator's website / Manual settings menu |
| Polarization | Vertical (V) or Horizontal (H) | Transponder parameters |
| Flow rate (SR) | Symbol Rate, data transfer speed | Operator's website |
| FEC | Degree of error correction | Automatically or the operator's website |
⚠️ Attention: When installed CAM-The module must make sure that the TV is off the socket. hot connection of the module can cause it to burn or damage the slot. CI+.
If channels are found but not opened ("No signal" or "encoded"), check the card activation with the provider. Also make sure the module is inserted before clicking and oriented by the correct side indicated on the TV body.
Installation of applications for IPTV
Modern Smart TVs allow you to watch TV over the Internet using IPTV technology, which gives you access to thousands of channels in high quality without being tied to an antenna cable, and you need a stable network connection and a player app to do that.
The most popular solutions for the Android platform TV Apps Peers.TV, Vintera TV, OTT Player or TiviMate. These can be found in the official Google Play Store or installed manually through the USB-storage device if the store is not available.
Once you install the app, run it. Some services provide a free basic channel package immediately after you register. Access to the extended list may require you to enter a playlist (m3u links) that your IPTV provider provides or that can be found in open sources.
Where can I get an IPTV playlist?
The advantage of IPTV is that it can view the archive of transmissions and pause the airwaves. The quality of the picture depends solely on the speed of your Internet connection. For viewing channels in 4K, it is recommended to watch at least 25-30 Mbit / s.
Addressing common problems
Even with the right setup, there may be failures. If the Xiaomi TV doesn't find channels, first check if the right region is selected. In your system settings, specify your country of residence, as frequency plans and broadcast standards vary.
A common problem is the "no signal" or "no signal" message, which indicates a weak signal level. Try reconnecting the antenna cable, checking its integrity or amplifying the signal with an active amplifier, in some cases, resetting the channel settings to factory and restarting the auto search.
If there are channels but no audio, check the audio settings in the TV menu. Make sure you choose the correct audio output format (for example, PCM instead of Auto if there are compatibility issues), and check if there is a "Subtitles Only" or "Hearing-impaired" mode that can change the audio track.
- 🔄 Reset the image and sound settings to factory values.
- 🔌 Restart the TV completely off the network 1-2 minute.
- 📡 Check the antenna on another device to rule out its malfunction.
In rare cases, the problem may be a software failure of the operating system itself. Check for firmware updates in Settings → About TV → System Update. Installing the current version of the software often fixes the bugs in the tuner.
💡
90% of channel setup problems are solved by checking the physical connection of the antenna cable and choosing the right region in the TV settings.
