Owners of modern Xiaomi Mi TVs often face the need to initially configure the device after buying or moving. Channel setup is one of the first steps, as it is the terrestrial or cable TV remains the main source of content for many users. The process can seem confusing due to the features of the Android TV or PatchWall operating system, which are used in different regions.
The quality of the signal reception depends on the correct connection of the antenna and the choice of broadcast region, errors at this stage can lead to a lack of image, image stratification or complete absence of the list of available stations. It is important to understand the difference between analog and digital broadcasting DVB-T2, since modern models are focused on the digital standard.
In this article, we will take a detailed look at all stages of the receiver configuration, from the physical connection of the cable to fine-tuning the frequencies manually. You will learn how to fix common signal problems and optimize the playlist for comfortable viewing. Follow the instructions carefully to avoid having to re-do the procedure.
Preparation of equipment and connection check
Before you go to software settings, you need to make sure the physical integrity of all connections.The antenna cable must be tightly inserted into the corresponding connector on the back of the TV, which is usually marked as Antenna In or RF If you use an external digital receiver or satellite set-top box, the connection is via HDMI-port, and the setting of channels occurs on the external device, not in the menu of the TV.
Make sure your antenna is capable of receiving DVB-T2. Old room antennas may not provide stable signal levels in areas with uncertain reception. For apartment buildings, a collective antenna is often enough, but in the private sector, a directional street model with an amplifier may be required.
⚠️ Warning: If you are using an active antenna with an amplifier, make sure that the menu of the TV activates the function "Power antenna.
After checking the cables, turn on the TV and wait for the operating system to load. Don't try to look for channels if the antenna is disabled or damaged, as this can take a long time and fail. Connection stability is a key factor in successful automatic scanning.
💡
Use a cable with copper and quality connectors to minimize signal loss, especially if the cable length is more than 5 meters.
Automatic setup of digital channels
The easiest and most common way to access television is to run an automatic search. To do this, go to the main menu and find the Settings section, which is often indicated by the gear ikon in the upper right corner of the screen. In the list that opens, you need to select Channels or Television, and then click on the Channel Search option.
If the cable is directly connected to the antenna input, choose Ether (DVB-T/T2) or Cable (DVB-C) TV, depending on the type of your network. When choosing a cable broadcast, the provider may require additional parameters, such as network frequency or flow rate, which are usually provided by the operator's technical support.
☑️ Checking before auto search
Once the launch is confirmed, the frequency scanning process will begin, the progress bar and the number of channels found will be displayed on the screen, at which point it is not recommended to interrupt the process, as this may lead to the preservation of an incomplete list or errors in the channel database. The scanning time varies from 3 to 10 minutes depending on the number of frequencies available.
When the procedure is completed, the TV will report the TV and radio channels found, and if the number of channels found is significantly lower than expected (for example, less than 10 for digital broadcasting in a major city), this indicates signal problems or the wrong type of antenna in the settings.
💡
Automatic search finds all available frequencies, but can skip low signal channels that have to be added manually.
Manual setting and list editing
In situations where automatic mode has not found the required frequencies, or if you need to add a channel of a particular radio station, manual setting is used. This method requires knowing the exact frequency of the broadcast, which can be found on the operator's website or in technical directories for your region. Go to the channel menu and select the option Manual setting or Frequencies.
In the window that opens, you need to enter the signal parameters. For digital terrestrial television, this is usually the frequency range of 170-850 MHz. Enter the values carefully using the remote control. After entering the frequency, press the scan start button, and the TV will try to capture the signal on this wave.
| Parameter | Description | Recommended value |
|---|---|---|
| Frequency (Frequency) | Channel number or frequency in MHz | Depends on the region (e.g. 546 MHz) |
| Network (Network) | Type of broadcast network | DVB-T2 |
| Modulation. | Signal encoding method | 64 QAM or Automatically |
| Bandwidth | Channel width | 8 MHz |
Once a signal is successfully captured, you can edit a shared channel list, Channel Editor allows you to change the order, hide unnecessary duplicates, or tag selected stations, which is especially useful for parents who want to restrict children's access to certain content, or for users who prefer a specific numbering.
Satellite and cable TV setup
If you use a cable provider that doesn't provide a separate set-top box, you're set up via the TV interface. Often you need to choose DVB-C. In some cases, the providers encrypt the signal, and then you'll need a CI+ access module (Common Interface) that inserts the operator card. The card slot is usually on the side or back panel.
The situation is different for satellite TV. Xiaomi TVs rarely have built-in DVB-S2 tuners. So you'll need an external receiver to receive the satellite signal. The setup in this case is to switch the TV to HDMI mode and set up channels already on the external device according to the instructions of the satellite operator.
When connecting via CI+, make sure the card is inserted on the correct side and all the way up. Once the TV is turned on, the system must automatically read the card data and update the list of available channel packets. If this does not happen, contact your provider to update your access keys.
Using applications for IPTV
Modern Smart TVs allow you to watch TV over the Internet using IPTV technology. This is a great option for places with poor air signal. To implement this idea, you need to install a special application from the Google Play Store. Popular solutions are Peers.TV, Wink, Okko or universal players like VLC and OTT Navigator.
For universal players you will need a playlist in the format.m3u, It's a service that is provided by an ISP or is publicly available. Once you install the application, run it, select the data source (file or file). URL-address) and start scanning the list. Channels will appear in the application interface, not in the standard tuner of the TV.
⚠️ Attention: For viewing IPTV high-end (HD/4K) A stable Internet connection at least a speed 20 Mbit/s. Buffering and delays are possible when using Wi-Fi, so cable connection is recommended LAN.
The advantage of this method is the ability to view the archive of transmissions and pause live, if supported by the service provider, and the list of channels can be synchronized between the TV and smartphone, which adds additional comfort to use.
Solving Signal and Image Quality Problems
A common problem for users is the appearance of a message "No signal" or the constant appearance of artifacts on the screen (square, fade).First of all, check the signal level in the information menu (usually called by the Info or Display button on the remote). If the level is below 60%, try changing the position of the antenna or using an amplifier.
If the channels are gone after the system update, reset the channel settings to factory values and repeat the search procedure. Sometimes software failures cause damage to the frequency database, and it is also worth checking whether the antenna cable has moved away from the connector, as vibration or sloppy cleaning may have disrupted the contact.
What if the TV doesn’t see any channels?
If you have an image but no sound or it's distorted, check the audio settings. Switch audio mode from Dolby Digital to PCM if your audio system doesn't support multichannel formats. This is a common problem when you connect older sound bars or headphones.
💡
The image quality depends on the signal level: at a level below 50%, interruptions are possible, above 80% - a stable picture without artifacts.
