Digital terrestrial television DVB-T2 It has become the standard for free viewing. 20+ channels are of high quality, but many owners of Xiaomi TVs (Mi series) TV 4A/4S/5X/P1 They have difficulty setting up the first setup, even if you have a properly connected antenna, where the TV can't find channels, shows no signal, or only stores a fraction of multiplexes. MIUI TV 2023β2026 Years and Typical Errors.
It is important to understand that the channel search algorithm on Xiaomi is different from Samsung or Samsung. LG: There is no universal βmaster of settingsβ, and the signal parameters are hidden in the depths of the menu. Weβll break down automatic and manual search, explain why a TV may not see some channels (for example, the first multiplex often goes missing due to a weak signal or outdated firmware, even though the antenna is connected correctly), and show you how to update the channel list without completely resetting.
If you've tried setting up your TV before, but you've encountered a "No Service" or "Weak Signal" error, there's a diagnostic section at the end of this article, where we analyze the reasons for the lack of power on the antenna amplifier to the wrong regional settings. For convenience, we've added checklists and surveys to help you navigate faster.
1.Preparation: What you need to set up digital channels
Before you start searching for channels, make sure you have everything you need. Without proper preparation, even the perfect settings in Xiaomiβs menu wonβt work.
Mandatory conditions:
- πΆ Operating antenna DVB-T2 (Indoor or outdoor. Remote regions require a powered amplifier 5V/12V.
- π F connector cable (not F connector) RCA Β«Tulip!) Check if the cable behind the TV is bent.
- π Digital TV coverage in your area, check out the RTRS website (enter address).
- β‘ Power: The TV must be connected to the network 220V, Not working with Power Bank.
In addition, for a stable signal:
- π Splitter (if the antenna is connected to several TVs); cheap "triplets" weaken the signal by 30-50%.
- π‘ Amplifier (if you live further than 15 km from the tower or in the zone of weak signal). L-032 terra HA123 suitable for most regions.
- π§ adapter IEC β F, if the antenna has an old connector.
β οΈ Note: If you use a satellite antenna (for example, for Tricolor), you can not set up digital channels through it - you need a separate receiver. TV It only supports broadcasting DVB-T2.
Before you plug in the antenna, turn off the TV socket, which will prevent power surges that could damage the tuner. ANT IN (usually located on the side or back) turn on the TV and go to the settings.
π‘
If you have Mi. TV P1 Or, newer, check if the antenna connector is covered with a decorative plug, which comes in a separate set of models and can block the signal.
2. Automatic channel search: step-by-step instructions
This is the easiest way to do this, and it works 80 percent of the time, but automatic search can miss some channels if the signal is weak or the menu is incorrect.
How to start:
- Press the Menu button on the remote (or βοΈ Settings in the upper right corner of the screen).
- Go to Settings. β Channels β Channel setting β On-air TV (DVB-T).
- Select Automatic Search.
- Please indicate the country - Russia (for other countries, the frequency may vary).
- In the Search Mode field, select Digital Channels (DVB-T2).
- Press Start and wait until it is finished (it will take 3-10 minutes).
If the search is successful, the TV will keep the channels found in the list, but users often face problems:
- π΄ Not all multiplexes are found (for example, only 10 channels instead of 20).
- π‘ Signal quality below 70% β possible βsprinklingβ of the picture.
- π’ Channels found but not saved (disappeared after reboot).
β οΈ Warning: If the TV finds channels but they donβt show (black screen or no signal), check if the hotel mode is on the menu (Settings) β System system β Hotel mode: In this mode, the air TV can be blocked.
Check the connection of the antenna to the connector ANT IN|
Make sure that the mode is selected DVB-T2 (not DVB-C or DVB-S)|
Update the TV firmware (Settings) β On TV. β Updating the system)|
Try manual search (instructions in the next section)-->
Manual channel search: when the machine is not working
If the automatic search fails, you'll have to enter multiplex frequencies manually, which takes longer, but guarantees tuning even when the signal is weak.
How to find frequencies for your region:
- Go to the RTRS website.
- Enter your address in the search box.
- Remember channel numbers (e.g. 24 TVKs, 32 TVKs) and frequencies (e.g. 498 MHz, 562 MHz).
Manual search instructions:
- Go to Settings β Channels β Channels β Manual search.
- Select Digital Channels (DVB-T2).
- Enter the frequency of the first multiplex (e.g., 498).
- Click Search. If you find a signal, the TV will tell you to save the channels.
- Repeat for the second multiplex (e.g., 562).
If the TV doesnβt find a signal at a known frequency, try:
- π Change the polarization of the antenna (turn it 90 degrees).
- πΆ Move the antenna closer to the window or above.
- π Connect the amplifier (if the signal is weak).
| Problem. | Possible cause | Decision |
|---|---|---|
| No signal on all frequencies. | The antenna is not connected or the cable is damaged. | Check the connection, replace the cable. |
| There's only 1 multiplex. | Weak signal or incorrect antenna orientation | Use the amplifier, turn the antenna. |
| Canals found, but not shown | Incompatible broadcast format (e.g, HEVC) | Update the TV firmware |
| Search hangs at 0%. | Failure of the software or incorrect regional settings | Reset channel settings (Settings) β Channels β Reset) |
What if the manual search does not find a single channel?
4. Signal optimization: how to improve reception
Even if channels are found, the quality of the channels may be poor: the image crumbles, the sound is interrupted, or some channels periodically disappear, due to weak signal or interference.
Ways to improve the signal:
- π‘ Point the antenna at the tower. Use a compass or a map of the RTR to determine the direction.
- π Remove the extension cords. Each adapter and cable extension reduces the signal by 10 to 20%.
- π οΈ Replace the cable. Old cables with damaged wiring are causing interference β RG-6 copper-coated.
- π Connect power to the amplifier (if any). Some antennas require 5V or 12V, which are supplied through a special adapter.
On Xiaomi TVs, you can check the signal level in real time:
- While watching TV, press the Info button on the remote.
- At the top of the screen will appear indicator signal (%) and quality (%).
- If the signal is below 60%, and the quality jumps, the antenna needs to be improved.
Additional advice:
- π§οΈ In rainy weather, the signal may deteriorate β this is normal for on-air TV.
- π If you are in an apartment building, try using a collective antenna (if it is modern and supports it). DVB-T2).
- π΅ Disable nearby devices at 2.4 GHz (routers, microwaves) β they can cause interference.
π‘
If the signal level on the screen is 100%, but the quality is 0%, the problem is the wrong frequency or broadcast format. Try manually specifying another TVK (for example, instead of 24 TVKs, try 34 TVKs for your region).
5. Firmware Update: Why It Matters to You DVB-T2
Xiaomi TVs regularly receive updates that fix tuner errors and add support for new broadcast formats (for example, for the first time, HEVC full-channel HD). If your TV is released before 2020, without an update, it may not find a portion of the channels.
How to update firmware:
- Go to Settings β About TV β System Update.
- Click Check for updates.
- If a new version is available, confirm installation. The TV will restart.
What to do if the update is not available:
- π Check your internet connection (the TV must be on the same network as the router).
- π Reboot the TV (unplug the socket for 30 seconds).
- π₯ Download the firmware manually from the Xiaomi site and install through USB.
β οΈ Warning: After updating the firmware, reset the channel settings (Settings) β Channels β Reset, otherwise the new tuner settings will not apply.
If the TV has stopped finding channels that used to work after the update, try:
- Return to the previous version of the firmware (via Settings) β On TV. β Rebuilding the system).
- Reset all settings to factory (Settings) β On TV. β Reset).
- Call for support for Xiaomi β perhaps in a new firmware bug with a tuner for your model.
π‘
On Mi TVs. TV P1 and newer after the update may appear option DVB-T2 HEVC Include it to find channels in high resolution (e.g. Match TV in the channel search menu). 1080p).
