Modern Xiaomi TVs based on Android TV or PatchWall are multimedia centers, but their basic function – broadcasting terrestrial TV – often requires manual adjustment after purchase. Users are faced with the fact that after the first turn on the screen remains black or shows a message about the absence of a signal, even if the antenna is connected, this is because automatic search does not always start immediately, or the wrong source of the signal is selected in the device menu.
The frequency scanning process depends on your receiver model and the firmware version installed. In some cases, you need to switch between digital and analog broadcasts, and in others, manually specify the type of connection, whether it is a provider cable or a room antenna. Understanding the logic of the MIUI for TV interface will allow you to avoid unnecessary actions and quickly enjoy your favorite transmissions in high resolution.
In this article, we will take a detailed look at all the steps of the setup, from the physical connection of the cable to fine-tuning the frequencies manually if the automatic mode failed, and learn how to interpret the system signals correctly and what to do if the list of channels is left empty after the scan is completed.
Preparation of equipment and inspection of connections
Before you go to software settings, you need to make sure that the physical integrity of the signal chain is not the software, but the simple lack of contact or damage to the cable. Check whether the antenna plug is securely inserted into the ANT IN or DVB-T/T2 connector on the back of the TV. If you use a splitter to split the signal into multiple devices, make sure that it is working.
The quality of the received signal depends on the type of antenna and its location. DVB-T2 In areas of uncertain reception may require an active antenna with external power. Make sure that the power supply antenna (if any) is included in the socket, and USB-The port of the TV to which it is connected is capable of producing sufficient current.
⚠️ Warning: Do not attempt to insert the antenna cable by force unless it enters the connector.F-type connectors have a specific stroke, and excessive force can damage the TV's internal slot thread.
If you use cable TV, check the integrity of the cable itself and the absence of strong inflections. For satellite TV, make sure that the receiver (if external) is on and the correct source of the HDMI signal is selected. If you use a room antenna, try to change its position or direction, as metal structures in the walls can shield the signal.
☑️ Checking before setting up
Automatic Channel Configuration through the Menu
The most common and easiest way to find broadcasting is to use the built-in customizator. The interface can vary depending on whether the shell version is installed: global Android TV or localized PatchWall. In most cases, the system will prompt you to start the search when you first turn on, but if this step was missed, you can manually initiate it through the main menu.
To start the process, go to the settings section using the remote control. Navigation is done using the arrow buttons and the central confirmation button. You need to find the setting for the TV, which is usually indicated by the antenna or satellite dish icon. On Android TV, the path often looks like Settings → Channels → Channel settings.
Once the signal source (antenna or cable) is selected, the system will suggest that you select a search mode, and it is recommended that you choose a full or automatic search so that the device can scan the entire frequency range on its own, a process that can take from 3 to 10 minutes depending on the number of multiplexes available in your area, and during the scan, the screen will display the progress bar and the number of channels found.
It is important not to interrupt the scanning process and turn off the TV until it reaches 100%. If you are using a digital antenna, make sure that the settings select the type of signal Digital or DVB-T2, not Analog, otherwise the TV will look for analog channels, broadcasting which in many regions has already stopped.
Manual frequency setting and list editing
Sometimes automatic mode can't find all available channels because of weak signal or specific provider settings, and in such cases, manual adjustments can be made to specify the exact frequency or channel number for scanning, especially for cable operators who don't use standard frequency grids.
To go manually, select Manual Search or Manual Scan from the channel search menu, where you need to enter a frequency into MHz or channel number, which can be found on your provider's website or on specialized resources such as an on-air coverage map of RTRS. Enter data carefully using a digital panel on the remote or on-screen keyboard.
| Parameter | Description | Typical value |
|---|---|---|
| Frequency | carrier frequency | 498 MHz - 850 MHz |
| Network | Broadcast network ID | Auto / 1-65535 |
| Modulation. | Type of signal encoding | QAM 64 / QAM 256 |
| The stripe | Bandwidth | 8 MHz |
Once you enter the parameters, press Search or Connect. The TV will try to get the signal at that frequency. If there's a signal, you'll see the quality and power level. If the signal level is too low, try repositioning the antenna or checking the connections. Once you've found the channel, you can save it by adding it to the general list.
What if the channels are there but no image?
Configuring DVB-T2 Digital Television
DVB-T2 is the main standard for digital broadcasting. Xiaomi TVs are equipped with a built-in tuner that supports this format, which eliminates the need to buy additional consoles. However, to work correctly, the TV must support the H.264 codec (MPEG-4), which is relevant for all modern models of the brand.
When setting up DVB-T2, it is critical to choose the right country. The TV settings menu often requires you to specify the region. If you choose the wrong country, the frequency list may not match your location and the search will not yield results. For Russia and CIS countries, the choice of Russia, Ukraine or Other is usually suitable if a particular country is not on the list.
When you search, make sure that the antenna switch is in the antenna position, not the cable. The digital signal is more sensitive to interference than the analog signal, so the quality of the cable and connector is crucial. Use a 75 Ohm cable with a copper central vein.
💡
Use the channel sorting feature after searching to place your favorite channels at the top of the list, which can be done through the channel list editing menu, moving them using color buttons on the remote or on-screen instructions.
Solving problems with signal search and quality
Even if you set it up properly, you may find that you can't find channels or the image is broken down into dice, and first check the signal level in the TV's information menu (usually called by the Info or Display button). If the level is below 50-60%, you can't have a stable picture.
One of the common causes of problems is outdated software. Manufacturers regularly release updates that improve tuner performance and system stability. Go to Settings → About TV → System update and check for new firmware versions. The update can fix errors of the drivers responsible for receiving the signal.
⚠️ Note: When updating your firmware, make sure the TV is connected to the network via stable Wi-Fi or Ethernet cable. interrupting the download or installing the update may cause the TV software to malfunction.
If the problem persists, try resetting the channel to factory values and running the search again. Sometimes scan errors accumulate in memory, and a complete cleanup of the list helps the tuner to “see” all available multiplexes again, and it is also worth checking whether the Auto Channel Update feature is enabled, which can periodically reset your settings.
💡
The quality of the digital TV image is independent of the settings of the TV, if the signal is received, the picture is either perfect or completely absent (the principle of digital signal).
Applications and alternative sources
Owners of Xiaomi TVs with Android TV have the unique advantage of installing third-party TV watching apps. If the over-the-air antenna does not work, you can use IPTV or online cinemas that only need the Internet.
