Modern Xiaomi TVs running on Android TV or Google TV offer users a wide range of multimedia features. However, the basic function of any TV receiver is the ability to watch digital broadcasting. Many owners of new models face difficulties in initial configuration, as the menu interface may differ from the usual systems of other manufacturers. The correct configuration of the DVB-T2 tuner allows you to enjoy a quality image without the need for additional consoles.
The frequency scanning process requires prior equipment preparation and understanding of how a digital signal works. Unlike analog broadcasting, which is gradually becoming a thing of the past, digital signal requires more precise antenna input tuning and the right search parameters. Errors in connecting or choosing the type of antenna can lead to the TV not finding any channel, even if the repeater is in close proximity. In this article, we will discuss in detail all the stages of setting, from connecting the cable to manual frequency adjustment.
It is important to understand that the menu interface may vary slightly depending on the version of the MIUI for TV firmware and the region for which the device is intended. However, the logic of actions remains the same for all models, whether it is a budget Mi TV Stick or flagship Mi QLED TV. Following the algorithm of actions will avoid common errors and save time. Below is a detailed plan of action that is relevant for most current models of Xiaomi TVs.
Preparation of equipment and signal verification
Before you start software setup, you need to make sure that the equipment is physically ready to work. DVB-T2 digital television is sensitive to connection quality, so any defect in the cable or connector can cause the lack of image. First check the condition of the antenna cable: it should not be clogged, and the plug should sit tightly in the socket of the TV. If you use a room antenna, make sure that it has an integrated amplifier, especially if you are far from the TV tower.
For owners of private homes or apartments located in the area of insecure reception, an external signal amplifier becomes a critical element. The amplifiers built into the antenna are often powered by the 220V network, and they need to be plugged into the socket. Some modern models of antennas receive power directly from the TV, but in this case, the corresponding voltage supply option should be activated in the TV menu. Without this step, even the most expensive antenna will work as a simple piece of wire.
It is also worth checking if your model supports the built-in tuner. DVB-T2. Almost all Xiaomi TVs officially supplied to CIS countries and Europe are equipped with the necessary module, however, if the device is brought from China without global firmware, the built-in tuner can be sharpened to the standard. DTMB, which is not compatible with European DVB-T2. The only solution is to buy from outside. USB-For standard situations, simply connect the antenna cable to the appropriate socket marked Antenna In or RF In.
⚠️ Warning: Never connect an antenna cable to a sat-in socket unless your TV supports satellite TV directly.
Primary TV setup and region selection
When you first turn on a new TV or reset it to a factory setting, the system will suggest you go through the initial configuration. One of the key steps is choosing the country and language. This step directly affects the available frequency ranges and the order of channel sorting. If you choose the wrong country, the TV can start searching on a frequency grid that is not used in your region, which will result in zero scanning result.
While the system may request Wi-Fi connectivity during the setup process, while the Internet is not required to watch TV on air, it will allow the TV to automatically update the channel database and update the list of available frequencies via the Internet. This is especially useful if your region has recently undergone frequency reform or relays. Once connected, the system will offer to update the software - agree, since new versions of Android TV often fix tuner errors.
If the TV has been in use but you want to reconfigure the channels, it is recommended to perform a full reset, or at least reset the channel settings.This will clear old, possibly irrelevant frequency data. Go to the settings section, find General or System, and select Reset. Once rebooted, the device will be ready to be clean set up from scratch, which will eliminate conflicts of old channel profiles.
Automatic search for digital channels
The easiest and most common way to set up a TV is to use automatic search. The TV algorithm will scan the entire available frequency range, identify the signals and store the programs found. To run this process, you need to go to the appropriate settings menu. Depending on the version of the PatchWall interface or pure Android TV, the path may be slightly different, but the overall logic is maintained.
Press the menu button on the remote, often indicated by three dots or a gear. In the window that opens, select Settings. Next, you need to find the channel section. It can be called Channels, Broadcasts or Logins. Inside this section, select Channel Configuration or Channel Search. The system will warn you that the current list will be updated, confirm the action.
In the menu that appears, select the source of the signal. If you're interested in terrestrial television, select Etheric TV or Antenna. Don't confuse it with Cable TV unless you use a provider that broadcasts the signal through a coaxial cable without encryption. After selecting the source, click AutoSearch. The process can take from 3 to 10 minutes depending on the number of multiplexes available and the signal power.
☑️ Checklist of automatic search
During the scan, the screen will display the progress bar and the number of channels found. At this point, it is not recommended to turn off the TV or switch the signal sources. If the search is complete but the channels are not found, check again the antenna connection. If the channels are found, the system will suggest sorting them or immediately go to viewing. Usually, the last channel viewed or the first one on the list is turned on by default.
Manual tuning and working with frequencies
In situations where automatic search does not find all available channels or finds them with errors (fading, artifacts), you need to resort to manual adjustment. This allows you to force the scan at the specific frequency at which the nearest repeater broadcasts.
In the channel settings menu, select Manual Setup or Manual Search. You will see a window with frequency parameters. Here you will see fields for channel number input (frequency range) and bandwidth. In Russia and CIS countries, the 8 MHz band for DVB-T2 is used. The channel number corresponds to a physical frequency, for example, the 30th channel is 546 MHz. By entering data manually, you make the tuner ignore weak signals and focus on a particular multiplex.
Once you enter the parameters, press Search or Scan. The TV will show you the signal level scale and the quality scale. The signal level shows the power, and the quality shows the absence of errors in the data stream. Your task is to achieve maximum values for both parameters. If the quality scale is jumping or low, try to rotate the antenna or change its position. Once the indicators stabilize, click Save or Add to enter the found packet of channels into memory.

Sorting and editing the channel list
Once channels are successfully searched, it is often necessary to organize them. Standard numbering can be inconvenient if federal channels are scattered in dozens and regional channels are inserted between them. Xiaomi TV interface allows you to edit the list, change the order and remove unnecessary positions. This is especially true for families with children to remove unnecessary information or religious channels from quick access.
To enter edit mode, go to the channel menu (usually by pressing the list button on the remote) and find Edit or Channel Management. In the list that opens, you will see all the programs found. By highlighting each channel, you can move it up or down the list, changing its serial number, for example, you can make the First channel appear on button 1, and Russia-1 on button 2.
There's also a lock or hide feature on this menu. If you don't want a particular channel to be displayed when you switch, select it and check Hide or Skip. Hidden channels don't disappear from memory completely, they're just ignored when you switch automatically. You'll have to go back to editing mode and remove the restriction to view them. This is a handy tool for personalizing content.

Solving Signal and Image Quality Problems
Even with the right setup, users can face problems: the picture falls into squares, the sound falls behind the video or the channels periodically disappear. The most common reason is insufficient signal level. Digital TV works on an all-or-nothing principle: if the signal level falls below a certain threshold, the image completely disappears, unlike analog, where it was just snow, so stability is more important than peak power.
If you're looking at artifacts, try replacing the antenna cable. Cheap cables with thin central vein and one layer of shielding do a poor job of handling high DVB-T2 frequencies. Use a dual-shielded cable and a copper central vein. Also check contacts: oxidized plug can cause significant losses. In some cases, installing an external signal amplifier closer to the antenna rather than the TV helps.
⚠️ Warning: Using an overly powerful amplifier in the confident reception area (near the TV tower) can overload the tuner and completely lose the signal.
Another cause of problems may be interference from home appliances or LTE-Cellular operators use frequencies close to television, and if a cell tower is near an antenna, you may need to install a cell tower. LTE-It's a small device that crashes into a cable in front of a TV and cuts off mobile frequencies, leaving only the television range.

Tip: If the signal is weak, try to disconnect all other devices from the antenna cable (video recorders, receivers) and connect the antenna directly to the TV for inspection.
