Modern Xiaomi Mi TV and Redmi TV are powerful multimedia centers, but their primary function - playback of TV - often raises questions among users immediately after purchase. The process of setting up channels on these devices is significantly different from the usual algorithms used in older models of TVs of other brands, due to the features of the Android TV or PatchWall operating system. Understanding these nuances will avoid common mistakes and quickly access high-quality digital image.
First of all, you need to make sure that the signal source is connected correctly, whether it is a room antenna, a satellite receiver or a provider cable. DVB-T2 digital broadcasting requires a high-quality connection, since the signal processing software on Xiaomi is very sensitive to interference at the input. If you have just unpacked the device, do not rush to immediately start an automatic search, having previously checked all physical connections and making sure that the antenna cable is tightly inserted into the RF In or Antenna connector.
Importantly, the interface may vary slightly depending on the firmware version and regional modification of the device. However, the basic logic of the system remains the same for all models, including the Mi TV P1, Mi TV 4S and older versions. In this guide, we will take a detailed look at each step, paying attention to the hidden settings and methods for solving typical problems faced by owners of smart TVs from Xiaomi.
Preparation of equipment and signal verification
Before you go into software settings, it is critical to ensure a stable input signal. Unlike analog television, where the bad signal manifested itself in the "snow" on the screen, the digital format DVB-T2 works on the principle of "all or nothing." If the signal level is below a certain threshold, the image will simply disappear or turn into cubes, so the quality of the antenna and cable should be given special attention.
If you use a room antenna, try to place it as close as possible to the window facing the nearest TV tower. Country house owners or residents of remote areas may need an active antenna with an external amplifier powered by the network or USB-Xiaomi often provides power via a TV port. USB, But in some cases, the port may not be enough power, and you will need a separate power supply for the amplifier.
💡
Use a cable with copper and quality connectors, as cheap low-cost low-cost cables can cause signal loss at decimeter frequencies.
Check the integrity of the antenna cable over its entire length: it should not be clamped, severe inflections or traces of damage to insulation by pets. Even microscopic damage to the shielding braid can cause the TV to fail to sync with broadcast frequency. Make sure that adapters, if used, sit tightly in the nests and do not stagger when touched.
Search and install channels through the settings menu
The main process of scanning the air is through the system menu of the device. Android TV interface may hide some options depending on the shell installed, but the standard path usually remains the same for most models. You will need a remote control to navigate menu items and activate the search process.
To start, click the settings button (usually indicated by a gear) on the remote or select the appropriate icon in the upper right corner of the main screen. Then sequentially follow the Settings → Channels → All Channels path. In some firmware versions, this item may be called simply Channels or located in the Broadcast TV section. This is where the Auto Search button starts, which initiates scanning of all available frequencies.
☑️ Checking before launching the search
Once launched, the system will suggest you to choose the type of connection: select the antenna (or DVB-T/T2) if you are receiving on-air broadcasts, or the cable if you use the services of the provider. When choosing a cable connection, you may need to additionally adjust the frequency range and transmission speed for which your operator provides data. In most cases, for on-air television, you just leave the default settings and click Search or OK.
The scanning process can take anywhere from 3 to 10 minutes depending on the number of multiplexes available in your area, the progress bar and the list of channels already found will be displayed on the screen during the search, and it is not recommended to interrupt this process, as this may lead to incorrect preservation of the playlist and require re-starting the procedure.
Manual frequency setting and list sorting
Automatic search doesn't always find all the channels available, especially if some transmitters are weaker than others, and in such cases, manual adjustments can be used to check specific frequencies and force them to be added to the list, especially in regions where new transmitters have recently been launched or the broadcast grid has changed.
To switch to manual settings, select Manual setting or Add channel from the channel menu, where you will need to enter the channel number or frequency in megahertz (MHz). Information about broadcast frequencies in your city can be found on the official website of the Russian TV and Radio Broadcasting Network (RTRS) or from the local cable television operator.
| Parameter | Value for DVB-T2 | Description |
|---|---|---|
| Type of scan | Full/Fast | Full searches for all frequencies, fast only changes |
| Frequency range | UHF (300-800 MHz) | The main range for digital broadcasting |
| Modulation. | 64 QAM / 256 QAM | Automatically or according to the operator |
| Symbolic speed | 6.75 Msps | Standard Value for Cable Networks |
Once you add channels manually, remember to sort the list to remove duplicates or empty channels that might have been saved with zero signal.The list sorting and editing function is in the same All Channels menu, usually called by long press of OK button or through the context menu (three dots), which will allow you to organize the numbering according to your preferences, for example, to bring your favorite federal channels to the first positions.
Why do you need manual adjustment?
Solving problems with image search and quality
Xiaomi TVs that fail to find channels or report no signal are among the most common. Often the reason is not because the TV itself malfunctions, but because of the wrong region or type of receiver, and may block digital channel searches if the country settings indicate a region where DVB-T2 is not supported or different from yours.
Check your region settings in the General → Region menu. Make sure your real country of residence is selected. If the problem persists after the region change, try resetting the channels to the factory and running the search again. Sometimes a software glitch in the channel database interferes with the correct scan, and a complete reset of this section solves the problem.
⚠️ Note: If the TV is writing "No signal" with the antenna on, check if the "Hotel" or "Demo" mode is activated. In these modes, channel search can be blocked software. Switch the use mode to "Home" in the system settings.
Image quality can also suffer from signal overload, which happens when using too powerful amplifiers in the confident reception zone. In such cases, try connecting the antenna directly without the amplifier, or use attenuator.
Using TV viewing apps
Android TV owners have a unique opportunity to go beyond the standard tuner. Google Play Store offers a variety of Internet TV (IPTV) apps, often providing more stable picture quality and a wide range of channels that are not available on air, especially for those who want to watch HD or 4K channels regardless of weather conditions.
Popular solutions are the applications Peers.TV, Lime HD TV or universal players like OTT Navigator and TiviMate, which require a stable Internet connection (preferably via cable) to work.
