Searching for Digital Channels on Xiaomi TV: A Complete Guide with Expert Tips

Digital TV standard DVB-T2 It has become the main source of free TV channels for millions of users, but customizing it on Xiaomi TVs (especially Mi models). TV 4S, Mi TV 5, Redmi Smart TV) Unlike analog broadcasting, where you just had to plug in an antenna and manually switch frequencies, digital channels require proper multiplex scanning, regional considerations, and sometimes even firmware updates.

In this article, we will look at all the ways of finding channels, from automatic scanning to manual frequency adjustment, explain why a TV can not find channels (even with a good signal), and give unique recommendations for optimizing reception for weak signals. If you encounter problems like “no signal”, “channels are not saved” or “constantly confused settings” – here you will find solutions.

Preparing Xiaomi TV for channel search

Before you start your search, make sure your Xiaomi is yours. TV You're ready to receive a digital signal, and many users skip that step, and then wonder why the channels aren't there:

• 📡 Antenna: Use a decimeter antenna (even a room antenna, but with an amplifier for weak signals). DVB-T2 not fit.
• 🔌 Connection: The cable from the antenna must be connected to the connector RF IN (or ANT IN) Check if the cable is damaged.
• 📶 Region: The settings of the TV must select your real region (not, for example, China or Europe), otherwise the scan will be on other frequencies.
• 🔄 Software Update: Outdated firmware may not support current multiplexes. Update your TV through Settings → On TV. → Updating the system.

If you live in a low-signal area (such as on the outskirts of a city or in a rural area), we recommend using an amplifier antenna and placing it closer to the window, and check if other devices operating at 2.4 GHz (Wi-Fi routers, microwaves) are interfering with the reception.

⚠️ Note: On Xiaomi TVs with version MIUI TV 3.0 may not be supported DVB-T2. Update your firmware or use an external one DVB-T2 receiver.

Automatic search for digital channels

This is the easiest way that most users can use, and it's automatically scanning the multiplexes that are available and storing the channels that are found.

1. Turn on the TV and press the Menu button on the remote (or Settings on some models).
2. Go to Settings → Channels → Channels → AutoSearch.
3. Select the signal source: antenna (DVB-T/T2).
4. Specify search type: Digital channels (or Digital channels) + analogue if you want to keep the old channels).
5. Press Start and wait until the process is complete (usually takes 3-10 minutes).

Once completed, the TV will show you a list of channels found. If multiplexes are found but the channels are not displayed, try resetting the channel settings (Settings) → Channels → Reset) and repeat the search.

If the automatic search didn't work, don't be quick to blame the TV, and it could be the lack of signal (e.g., you're out of coverage) or the region settings that are wrong. Try manually specifying multiplex frequencies for your city, and read about that in the next section.

Manual search of channels by frequency

If the automatic search didn't work, you'd have to enter multiplex frequencies manually, which is for regions with unstable signals, or if the TV doesn't recognize local towers, and first, find the actual frequencies for your city:

• 🌍 On the RTRS website (enter your locality in the search).
• 📱 In the mobile application "Telegid" or "DVB-T2 Info".
• 📡 On forums of local providers (for example, for Moscow it is 546 MHz and 578 MHz).

Now, do a manual search:

1. Go to Settings → Channels → Manual setting.
2. Choose. DVB-T2 source.
3. Enter the frequency of the first multiplex (e.g. 546,000 kHz – no spaces!).
4. Set the bandwidth: 8 MHz and Modulation: 256 QAM.
5. Click Search. If you find channels, repeat for the rest of the frequencies.

If the channels are not preserved after manual input of frequencies, check:

• 🔋 Is the antenna powered enough (if it is active).
• 📶 Are there any interferences with other devices (e.g, 4G-modem).
• 🔄 Is it correct? ID Networks (usually Auto).

⚠️ Note: Some Xiaomi models (e.g. Mi) TV 4A Early versions) manual frequency input may not work due to firmware limitations, in which case only an upgrade or external receiver will help.

Why is Xiaomi TV not finding digital channels?

If you did everything according to the instructions, but the channels never appeared, the reasons may be as follows:

1. Problems with antenna or cable

Check it out.

• 🔌 Integrity of the cable (whether there are excesses or damages).
• 📶 Signal quality: connect the antenna to another TV or receiver.
• 🔋 Does the antenna amplifier work (if any).

2. Incorrect settings of the region

The TV should be set to your country and region. → Language and region: If China or Europe is listed, change to Russia and repeat the search.

3.Outdated firmware

Firmware older than 2022 may not support current multiplexes.

1. Connect the TV to the Internet.
2. Go to Settings → About TV → System Update.
3. If the update is not, download the firmware from the official Xiaomi website and install it through the USB.

4. Interference or weak signal

The digital signal is sensitive to interference.

• 📍 Move the antenna closer to the window.
• 📵 Disable nearby Wi-Fi routers or microwaves.
• 🔄 Use a interference filter (sold in electronics stores).

💡

If the TV finds channels but they are constantly falling into pixels or the sound is interrupted, try to reduce the antenna gain (if it is adjustable) – sometimes too strong a signal also interferes.

Preservation and sorting of found channels

Once you've done a successful search, you save the channels and sort them for easy viewing. Here's how to do it on Xiaomi. TV:

1. Save: Once you've finished your search, click Ready or Save. The TV will prompt you to delete the recurring channels -- agree.
2. Sort: Go to Settings → Channels → Canal control, you can do it here:

Lockdown:

Lock down

If the channels disappear when you reboot the TV after saving, it may indicate damaged memory. Try resetting to factory settings (Settings) → On TV. → Reset) and repeat the search.

💡

After sorting the channels, click Save Changes - otherwise the next time you turn on the TV, the order will reset.

Updating the channel list and fixing problems

Digital TV is updated periodically: new channels are added, multiplex frequencies are changed. TV Always showed the current list, do a second search every 2-3 months:

1. Remove old channels: Settings → Channels → Canal reset.
2. Update the multiplex frequencies (check the current data on the RTRS website).
3. Run a full automatic search (not fast!).
4. If new channels don’t appear, try manually searching for the updated frequencies.

If some channels have disappeared after the update, it could mean:

• 📉 In your region, the broadcasting has been temporarily disabled (check the news on the RTRS website).
• 🔧 Modulation parameters have changed (try manually specifying the modulation parameters). QAM-64 instead QAM-256).
• 📡 Problems on the transmitting tower (wait 1-2 days and repeat the search).

⚠️ Note: On Xiaomi TVs with version MIUI TV below 4.0 Support for new video compression standards may not be available (e.g, HEVC/H.265). In this case, some channels will be displayed without sound or image.

Use of external DVB-T2 receiver

If the built-in tuner of your Xiaomi TV It can’t handle the signal (or it doesn’t, as on some Mi models). TV Stick, you can connect externally DVB-T2 It's a receiver:

• 📺 TVs without built-in tuner (for example, Xiaomi Mi) TV 4S 32" for certain regions).
• 📶 A weak signal area where a more sensitive antenna is needed.
• 🔄 Old models with outdated firmware.

To connect:

1. Buy a receiver with support DVB-T2 and HEVC (Like, Strong. SRT 8504 or BBK SMP143HDT2).
2. Connect the antenna to the receiver and the receiver to the TV through HDMI.
3. Configure the channels through the receiver menu (the instructions are usually included).
4. Select the signal source on the TV HDMI (source button).

Advantages of external receiver:

• ✅ More stable reception of weak signal.
• ✅ Support for new broadcasting standards.
• ✅ Possibility of recording the airwaves USB-accumulator.

Disadvantage – additional costs (from 1,500) ₽ But for regions with a problem signal, it's often the only solution.
