How to set up channels on a Xiaomi TV: the complete guide

Modern Xiaomi TVs with Android TV offer users ample opportunities to watch multimedia, but the basic function - receiving terrestrial television - often requires the correct initial configuration. Many owners face a situation when the screen remains black after connecting the antenna or shows a message about the absence of a signal, which causes confusion among inexperienced users. The process of setting channels on shiaomi TVs is not difficult, but it requires careful attention to choosing the source of the signal and correctly entering frequency parameters.

Unlike older button models, modern Smart TVs have a complex menu where it is easy to get confused if you do not know the logic of the developers of the PatchWall interface or pure Android. The key is to choose the right type of connection (antenna or cable provider) before starting a scan. In this article, we will discuss in detail all the stages of setting up digital terrestrial television (DVB-T2) and cable broadcasting, and also consider methods for solving common problems with signal reception.

Before you go to software settings, you need to make sure that the physical integrity of the connections is checked. Check whether the antenna plug is tightly inserted into the socket located on the back or side of the device. If you use an active antenna (with an amplifier), make sure that it is connected to the power source, as the passive receiver may not provide enough signal level for a stable picture in HD or 4K resolution.

Connecting the antenna and selecting the signal source

The first and most important step is to physically connect the receiver. On the back of a Xiaomi TV, you'll find a connector signed as Antenna In or RF In. This is where you need to insert a coaxial cable plug from a room or an external antenna. If you use cable TV, the same connector is connected to a wire from the provider that goes directly from the wall or outlet.

Once you've connected physically, you've got to switch the TV to tuner mode, and you've got to take the remote control and find the button that's responsible for choosing the source of the signal, which can be called Input, Source, or have a square icon with an arrow inside. By pressing this button, you will call the menu where you need to select the item. TV live TV. Don't confuse this regime with HDMI-entrances where consoles or consoles are connected.

If you have a digital TV menu on the screen that suggests you configure the channels, you are on the right track. In some cases, the system can automatically suggest that you start a search when you find a new connection. However, if you do not automatically start, you need to manually control through the main menu of the system. It is important to understand that without choosing the right signal source (DTV, ATV or SAT), frequency scanning will not give results.

Automatic Channel Configuration through the Menu

The easiest way to find all available transmissions is to use the autosearch function, which is ideal for most users, since the system itself will determine the required frequencies and store the programs found in the TV memory. To start the procedure, press the Menu button on the remote or select the gear icon in the upper right corner of the screen to enter the settings.

In the menu that opens, you need to find the TV configuration section. Depending on the version of the MIUI TV firmware or Android TV, this item can be called differently. Usually the path is: Settings → Channels → Channel Search or Broadcast → Channel configuration. Select the Auto Search option and confirm the action.

The system will warn you that the current channel list will be replaced by new data. Accept this if you are setting up the TV for the first time or if you have moved the antenna to a new location. The scanning process can take from 2 to 5 minutes depending on the number of multiplexes available in your area, at which time the screen will display the progress bar and the number of channels found.

Once the scan is complete, the TV will suggest sorting channels or skipping unnecessary ones. It is recommended to remove empty or broken positions immediately to make navigation easier in the future. If the automatic search found fewer than 20 channels (standard for Russia and many CIS countries), it is possible that the signal level is too low and manual adjustment or change of antenna is required.

Manual setting of frequencies and broadcast parameters

In situations where the automatic mode does not find channels or finds them with errors (stuttering images, desynchronizing sound), you have to resort to manual adjustment. This is especially true for residents of remote areas or when using specific equipment providers. To switch to this mode in the channel search menu, select the option Manual Search or Manual Scan.

Here you will need to enter the exact frequency parameters, which can be found on the website of your regional digital television operator or in the frequency directory. You will need to specify the type of scan (usually DVB-T2 for a number), the bandwidth (usually 8 MHz) and the specific frequency in MHz. It is also important to choose the right range if the TV supports several standards.

⚠️ Note: When manually setting, make sure you enter the frequency specifically for your city or neighborhood. Using the settings of the neighboring region will cause the TV to fail to decode the signal, and you will see a black screen instead of an image.

After entering the parameters, press the Scan or OK button. The TV will only check one frequency. If the signal is stable, you will see level and quality scales that should fill up by more than 60-70%. If the scales jump or are empty, try changing the position of the antenna slightly or increasing its gain in the power settings (if the antenna is active and the TV is supported).

Configuring cable television (DVB-C)

If you're connected to a cable provider, the setup process has its own peculiarities. Unlike an over-the-air antenna, here the signal comes via coaxial cable directly into the apartment, and often the providers use encryption or specific modulation parameters. First, make sure that the Cable or DVB-C mode is selected from the signal source menu, rather than the on-air TV.

In most cases, cable TV requires an access card (CAM-module in the Common Interface slot (CI+), You can then insert the module chip to the side of the Xiaomi logo before clicking, and then you can see the channel settings menu that will update the channel list through the click. CAM-The module that must be activated.

To automatically configure cable channels, select the Cable network type in the search options. If the provider does not provide automatic settings, you will have to search for them on the operator's website.

Solving Signal and Image Quality Problems

Even after successful channel search, users may encounter artifacts on the screen: a picture scattering into squares, a sound fading or a signal disappearing completely. The first cause of these problems is almost always insufficient signal level. Check the level indicator in the channel settings menu (usually called by the Info or i button on the remote).

If the signal level is low (less than 50%), try the following:

• 🔌 Check the integrity of the antenna cable: bending, damage to the insulation or oxidation of contacts in the plug can critically reduce the quality of reception.
• 📡 Change the direction of the antenna: even a small rotation of the room receiver can improve the signal on the antenna. 10-15%.
• 🔋 Check the power of the active antenna: if the antenna has a separate power supply, make sure it is connected to the network and the indicator is on.

Another common cause of problems is a tuner overheating or software failure. If the TV was running for a long time without a break, the internal components could heat up, which affects the sensitivity of the receiver. Let the device cool down. Also helps a full reset of channel settings and re-start the search, which eliminates errors in the frequency table.

💡

Use an antenna amplifier if the cable length from the antenna to the TV is more than 10 meters. Long cable inevitably weakens the signal, and the built-in TV amplifier may not be enough for stable operation.

In rare cases, problems can be caused by interference from household appliances. Microwave ovens, running wireless routers and powerful power supplies can create on-air. Try turning off nearby appliances and check if the picture has improved. If signal quality has dropped dramatically throughout the area, there may be preventive work on the repeater, information about this can be found on the websites of local operators.

Table of common errors and ways to eliminate them

For quick diagnosis of problems, use the summary table, which lists the typical symptoms and methods of their solution. This will help save time and avoid unnecessary calls of the master.

If neither of these methods works, it is worth checking the antenna on another TV to determine exactly where the problem lies: in the receiving device Xiaomi or in the external infrastructure. In case of a malfunction of the tuner itself (which is rare), the solution can be to buy an external console DVB-T2, connected via HDMI.

💡

The stability of digital reception depends not only on the TV, but also on the quality of the antenna track. Cheap cables and old antennas are often the main bottleneck of the entire system.
