In our country, digital TV broadcasting is ubiquitous, such popularity is due to its universal availability and exceptional ease of connection. From a technical point of view, it completely repeats broadcasting, but at the same time gives audio and video in a higher resolution.

However, sometimes users are faced with a situation where the TV receiver does not pick up channels. In our review, we will try to find out why this happens, and how to fix the situation.

Causes of malfunctions

If there is no image on the TV receiver screen, there may be dozens of reasons. In general, they fall into three categories:

  • hardware - that is, associated with incorrect connection or breakdown of the repeater;
  • programmatic - failure of antenna or set-top box settings;
  • external factors - in this case, the channels are lost due to reasons beyond the control of the user.

Let's dwell on each category in more detail.

Hardware

Most often, channels disappear due to elementary errors when wires are connected to different connectors that are not suitable for this.

The cause of the malfunction may be due to a lack of connection.

That is why, first of all, you should check the correct connection of all working elements of the device:

  • a digital antenna, as well as an amplifier, must be connected to different cables;
  • the receiver is connected to the TV receiver via an HDMI wire, otherwise it simply cannot see the tuner.

If all devices are connected correctly, but the channels are gone, then you need to make sure that each element is working . For example, a TV can be connected to a standard terrestrial antenna or a PC and see what the result will be. On the set-top box, it will be enough just to turn on the automatic tuning of channels - if they are absent, but the picture changes, therefore, the problem lies in the antenna.

The last thing to check is the incoming TV signal and its quality . To do this, go to the Internet at the address map. rtrs. рф and indicate your region of residence. As a result, you will receive a map showing the features of broadcasting within your settlement - the quality of its reception largely depends on the distance of the signal source.

If, when connecting a TV amplifier, you notice that the video sequence on the screen began to change, but at the same time remained of insufficient quality, then the current power of the repeater is not enough.

Software

Often, the reason for the absence of television channels is that the settings are lost or were incorrectly set by the equipment user by mistake. The following problems occur most often.

  • The channel in the TV receiver was selected incorrectly - in this case, you should switch according to the type of the connected cable, otherwise the receiver will only search for analog channels or will not do it at all.
  • Outdated firmware - the old software of the receiver from time to time ceases to be supported by the development company and in this case performs a low-quality search at various frequencies. That is why you need to check for new software and update it.

If you find a complete loss of all television channels, you should not immediately look for a system failure, most likely the reason lies in the action of external factors

  • Carrying out scheduled maintenance work on the repeater. Any equipment needs periodic maintenance, every few months work is mandatory to improve the quality of broadcasting. During such works, channels are often shown with interference or there is no broadcast at all. As a rule, at the end of the work, the quality of the incoming signal is restored.
  • Weather and climatic conditions can also be involved in the disappearance of broadcasting. Most often it is rain, thunderstorm, strong wind, high clouds. If such weather is typical for the region of residence, you should take care of installing a powerful antenna.

Sometimes users face a problem when the receiver finds almost all channels except one or two.

The reasons for this phenomenon may be the following factors

  • Performing technical work by the provider. As a rule, there is always information about this on the official website of the channel.
  • Termination of broadcasting. If you do not see a specific channel, then it is possible that he changed the operating frequency or completely turned off the digital broadcast - this data should also be on the channel's website.

Troubleshooting

The first thing to do if the TV tuner is not looking for TV channels is to make sure that the receiver supports DVB T2, and also check the type of coating used. There are three connection options in total:

  • ethereal - in this case, the antenna is connected directly to the receiver for free viewing of 20 channels;
  • cable - the wire connected to the receiver connects to the server of the provider broadcasting the transmission;
  • satellite - the signal goes to a dish-shaped antenna, from where it goes directly to the TV.

In order to check the coverage, it is necessary to study the map, which provides information about the location of the tower, as well as the quality of the received signals. You can view this information on the official website of the provider, the only thing that users need to do is to indicate the address of residence. After the data is uploaded to the system, it will become obvious whether an amplifier purchase is necessary.

Before purchasing an amplifier or repeater, the TV is checked for its digital connectivity . The main standard for such a connection is DVB T2. Since 2017, this format has been supported by almost all modern models. You can clarify the information on the website of the service provider by entering the name of the TV model - if it turns out that it is old, you will need to purchase an additional tuner.

Residents of large cities usually do not feel the need to buy an amplifier - even the most common outdoor antenna can be used for digital TV broadcasting.

In small towns, it is worth choosing options with an active amplifier - it will improve the quality of the incoming signal and ensure uninterrupted audio and video sequences.

Before buying, be sure to check the quality of the connecting cable for kinks or twists .- any defect can have the most adverse effect on its work. If defects are found on the cords, you can connect the kinks with a plug or replace the cable with a new one.

An important influence on the quality of signal reception is the location of the antenna . Sometimes, within the same room, the antenna can give a different broadcast quality. In case you cannot catch the channels, try moving the signal amplifier, put it in high places and perform other similar manipulations.

If we are talking about a conventional antenna, then it is better to try to place it in such a way that it is not obstructed by tree crowns, since any obstacles impair the signal.

A correctly performed channel search plays an important role; it ensures the stability of TV broadcasting . Setting up the system is not at all difficult: through the main menu you need to go to the "Settings" section, then select the correct type of connection and specify the antenna, then click the "Autosearch" option and wait for the download to finish.

When the channel is successfully saved, it is assigned a specific number on the remote control.

What if all else fails?

If you have tried a variety of options for setting up broadcasting and searching for digital television channels, but nevertheless, no solution to the malfunction has been found, most likely the reason lies in the antenna or the tuner itself. To be sure of their malfunction, you can try to connect another antenna or set-top box - in this case, you can understand whether the source of the problem lies in the repeater or in the television receiver itself . Any faulty device should be taken to a service center for diagnostics, professional technicians will find the cause of the problem and suggest measures to fix it.

Please note that if we are talking about the simplest home and outdoor antennas, then often their repair is more expensive than buying a new device . That is why, before deciding whether to agree to service, check the cost of the work.
