Modern Xiaomi Mi TVs and Redmi TVs are powerful multimedia centers that easily replace computers and game consoles. However, despite the abundance of smart features and streaming services, traditional terrestrial television remains the main source of information for millions of users. Many owners face difficulties in initial installation of equipment, not knowing how to connect the antenna correctly or where to find the settings of digital broadcasting.
The frequency scanning process on Android TV or PatchWall devices may be different from the usual algorithms of older kinescope models. It is important to consider not only the type of connection, but also the version of the firmware, as well as the region of use of the device. Errors in the initial configuration stage often lead to the fact that some channels are lost, displayed with artifacts, or not at all located in the system.
In this guide, we will take a detailed look at all the stages of equipment preparation, digital and analog signal tuning, and solving common image quality problems, and learn how to sort the broadcast list, update frequencies, and optimize the tuner for stable signal reception even in low-course conditions.
Preparation of equipment and signal verification
Before you start software setup, you need to make sure that all the components of the system are physically healthy. The digital tuner built into Xiaomi TVs is sensitive to the quality of the incoming signal, so the state of the antenna cable and the antenna itself plays a critical role. If you use a room antenna, make sure that it is located next to the window and directed towards the nearest TV tower.
For apartment dwellers, the most common thing to do is connect to a common-house network or a customized satellite dish. In the first case, check the integrity of the cable that runs from the outlet to the TV. Insulation damage or oxidized contacts can lead to loss of data packets and the message "No signal" or "Weak signal."
⚠️ Note: Do not connect the satellite receiver directly to the TV antenna input without an appropriate decoder or LNB-Converter, if you're not sure about the specifications of the equipment, it could damage the input tuner cascade.
If you are planning to use an external USB-tuner for specific formats or functionality extensions, make sure it is compatible with the Android operating system TV. Most of the built-in solutions support the standard DVB-T2, It's a staple for digital terrestrial broadcasting in many countries, and check that the antenna plug fits tightly into the Antenna In or Sat In socket on the back of the device.
Automatic setup of digital channels
The easiest and fastest way to access television is to use automatic search, and the system will scan the entire available frequency range and store the broadcasts found in memory, and first you need to enter the main menu by pressing the button with the image of the gear on the remote control or selecting the corresponding icon in the upper right corner of the screen.
In the settings menu that opens, find the TV section. Depending on the version of the PatchWall interface or pure Android TV, this item can be called differently. You usually need to go by Settings → Channels → Channels → Channels → Channels → Channel Tuner.
Select the antenna connection type (DVB-T/T2) for terrestrial digital television or cable (DVB-C) if the signal is coming from the provider. After selecting the source, start the scanning process. The TV will warn that the current channel list will be replaced by new data. Confirm the action and wait for the process to be completed, which can take from 2 to 10 minutes depending on the number of frequencies available.
☑️ Checking before auto search
The scan shows the progress bar and the number of channels found. Interrupting the process is not recommended, as this may lead to incorrect recording of the frequency grid. If the search is complete, but few channels are found (for example, less than 10 for on-air TV), try repeating the procedure by pre-checking the position of the antenna.
Manual setting and list editing
Automation doesn't always give the perfect result: channels can be confused, favorite regional stations can be missing, or broadcasting can be uncomfortable. In such cases, manual adjustment comes to the rescue, which allows you to enter the exact frequency of a particular multiplex or channel, which is especially true in areas of uncertain reception, where automatics "leap" weak signals.
To go manually, select Manual Search or Manual Tuning from the channel search menu, where you need to enter a megahertz (MHz) frequency or channel number, and you can find accurate broadcast frequencies in your region on official repeater sites or specialized digital TV resources.
| Parameter | Description | Typical value |
|---|---|---|
| Frequency | Operating frequency of multiplex | 498 MHz, 578 MHz |
| Modulation. | Signal encoding method | QAM 64 / QAM 256 |
| Strip width | Channel bandwidth | 8 MHz |
| Network | Type of broadcast network | Terrestrial (Ether) |
Once you enter the parameters, start a search. If the signal is stable, the TV will show the quality and strength of the signal as a percentage; if the readings are low, try the direction of the antenna by observing changes on the screen. Once the channel is successfully located, it can be saved by assigning a name or number to it.
Editing the list allows you to delete unnecessary information channels, radio stations or takes. Enter channel editing mode (usually the Options button or through the list menu), select an unnecessary channel and click Delete or Skip. Also available is the renaming function, which is convenient for assigning clear names to regional broadcasters.

Use Favorites to create a separate list of the 10-20 most important channels, which will eliminate the constant switching of hundreds of unnecessary stations when viewing.
Satellite and cable TV setup
Owners of models with built-in satellite tuner (DVB-S2) or connected to cable providers should choose the appropriate type of entry. Cable TV often requires choosing a provider from a list or entering network parameters provided by the operator. If your provider is not on the list, choose Others or Full Scan for full range scanning.
Satellite TV requires more precise tuning. You need to select the right satellite (such as Astra 4A, Hotbird or Express AMU1) from the list. The TV will automatically adjust the LNB (heterodyne) parameters, but in some cases they need to be entered manually, taking data from the instructions to the converter.
⚠️ Note: In addition to frequency settings, the module will be installed to receive encoded satellite channels. CI+ With the operator's access card, without the card, only open ones will be available (FTA) channel.
Search is similar to etheric: select a source, click Search and wait for the result. Cable operators can use different modulation standards, so if the automatic search did not work, check with the support network parameters (search start frequency, modulation, flow rate).
Sorting channels and creating profiles
Once all the channels are found, it's time to get things in order. The chaotic list of 100+ positions makes navigation difficult. Xiaomi's system lets you sort channels by type (TV, Radio), alphabetically or manually reorder them, which is especially handy if you want the main federal channels to be at the top of the list.
To change the order, go to the channel control menu and select sort mode. By moving items up or down, you form your own logical structure. Some versions of the software allow you to create multiple user profiles, where each family member will have their own sorted list of favorite shows.
The parental control feature deserves special attention, and you can block access to certain channels by installing a new system. PIN-This will prevent children from accidentally turning on age-restricted content. The lock is configured in the same channel list editing menu.
💡
Proper sorting and removal of garbage channels (technical, radio) speeds up switching between programs and makes navigation on the air more comfortable.
Solving Signal and Image Quality Problems
Even after setting it up properly, users can experience problems such as scattering the image onto the dice, losing the signal completely, or desynchronizing the sound, most often due to a physical connection or temporary interference, check if the antenna cable is compressed, and try reconnecting it to another connector if there are more than one.
If the signal is weak, an active antenna amplifier will help, but be careful: if the signal level is initially high, the amplifier can conversely overload the tuner and degrade the quality.
A common problem is to desynchronize the time and channel list after updating the firmware, in which case a full reset of the tuner to the factory settings helps, go to the channel settings and select Reset Channels or Factory Reset (only for the TV partition, not the entire TV), and then you have to go through the search again.
Settings → Device → About System → Reset (Caution: Complete System Reset)
Or
Settings → Channels → Resetting tuner settingsIf the channels are lost after scheduled work on the TV tower, you need to perform a rescan. TV towers often change the frequencies of broadcasting as part of equipment upgrades, and the old frequency list becomes irrelevant.
