Top reasons why digital channels on Samsung TV are not tuned in. How to troubleshoot problems

Digital television has already become a part of people’s daily lives. If you have a TV in your home and you can’t go to digital channels during tuning, you can solve the problem yourself. But first you need to find out the cause and diagnose. Some details may vary by model and brand of TV.

Hardware reasons

If the TV does not tune digital channels through the antenna, this indicates a malfunction or incorrect connection. To eliminate this problem, you need to check the correct connection of the TV to the antenna, the integrity of all cables, as well as the connection of wires to the correct sockets.

The digital antenna and amplifier are connected to the Samsung TV with separate cords. To check the health of devices, you need to find channels in automatic mode. If at the same time the picture on the TV changes, but there are no channels, the problem is precisely in the antenna.

To check the territorial coverage of the antenna, you need to go to the site http: //map.rtrs.rf/ and enter your region. The map will show the broadcasting territory in the specified region and area.

Why can’t I set up TV?

Digital television is a new way of broadcasting that transmits sound and image using signal coding. If the digital channels on your Samsung TV are not tuned in, you need to find out the problem. They are of several types.

Software glitches

Failure in the program most often happens through the fault of the user. During the settings, the parameters could be entered incorrectly or the frequency was entered by mistake. Perhaps the old STB software is not supported by the developer. In this case, you need to reinstall the software on the digital set-top box.

Solution to the problem

To solve the problem, it is necessary to carry out several steps in stages:

  • Check which antenna is installed. Digital TV requires a decimeter antenna.
  • Then check the wires so that the cable is intact and not broken in any of the sections.
  • Manually search for channels or update the firmware of the set-top box.
  • If you cannot set up paid channels, you should double-check the availability of payment.

If TV channels are broadcast using the Internet, then it is important to check the connection to the network and the availability of money on the balance without fail. In general, Samsung‘s digital connection looks like this:

  • Open the “Menu” tab, then find the “Broadcast” button there.
  • Press autosearch.
  • Then confirm by pressing the “Start” button.

If broadcasting is not configured in the menu, you need to select “Other operators” instead of cable TV and click “Full”. Then you need to set the required position using the remote control. You can also carry out manual tuning, but for this it is necessary to initially clarify the frequency of the multiplexes that are broadcast in a particular region.

If, when setting up the Samsung ue28f4000aw TV, it does not catch digital channels, then you need to make sure that in the Antenna item, the Cable item is pressed, and that the Digital channel is selected as the channel type. and Analog “. If the Samsung le22b350f2w model does not find a signal, then you can select only digital or only analog channels, and during setup you need to change the country and display a 4-digit pin code.

Regardless of the Samsung model, almost all have the ability to tune digital channels. For older brands, you will have to buy a special tuner. If the tuning did not work, the problem may be both in the TV itself and in the antenna. Therefore, first of all, you need to find the reason.

Algorithm for tuning digital channels

Regardless of the type of TV, the frequency setting is done according to the same scheme. What’s in the modern Samsung model, what’s in old devices. the principle of action is almost identical. First of all, there must be an appropriate antenna capable of receiving the signal of a TV tower broadcasting digital television. If the device picks up a signal, the adapter will offer to add it to the menu. After connecting it to the receiver, the setting will be carried out as follows.

  • You need to open the “Broadcast” settings menu.
  • Select automatic search.
  • Press the “Start” button.
  • The software will ask you to decide on the choice of the signal source: antenna or cable. The latter is selected if there is a cable TV broadcast.
  • When connecting the antenna, the device will offer to select a sub-directory of analog or digital channels, or you can configure a complete list, including both.
  • The last step is to run a “scan”.

If you are careful, there are many prompts in the TV menu, but it is important that the signal receiver is correctly installed and the T2 set-top box is connected.

If the TV does not pick up channels, you can use alternative methods of connecting digital frequencies using a cable or satellite box. To search in the first way, you need to connect the cable TV wire to the antenna connector. In the settings, by selecting the autosearch menu, a new window will appear. If you need to connect digital television, you must choose not cable TV, but “other operators”. In the presetting of cable television, click the “Full” item, which will allow you to select the search for digital channels only. Using the control panel, you can sort the channels, and put them in the desired positions.

Using satellite equipment, the connection is made with two types of cable. For these purposes, a high-frequency cable is connected to the antenna, connected to the receiver through the RF OUT jack. After connecting, you can connect the equipment to the network and start autosearch of channels on the receiver. The search will end when no signal appears. The receiver is connected to the TV set with a low-frequency “tulip” cable and the video mode is switched on. Then, through the menu with the sections “quality” and “signal strength”, you can adjust the dish. If the connection was made correctly, the channels found will be played back without interference.

Timeliness of software updates

Outdated software of the receiving equipment may be the cause of problems with setting up multiplex reception. On modern Smart TVs, the software is updated via the Internet, and if the TV does not catch digital channels, then you should check the update and run an automatic update.

The software of the set-top box with a DVB T2 tuner may also work incorrectly, which causes problems with the reception of digital signals. Installing a software update resolves the problem. On thematic forums and in the instructions for a specific model, you can get information on how to flash a TV set-top box.

Checking hardware capabilities

Owners of new TVs equipped with a digital DVB T2 tuner can watch broadcasts in a modern format without resorting to additional equipment. Other viewers need to connect a set-top box with a similar decoder to receive ECTV on their TV.

You can verify the technical capabilities of your TV receiver in the following ways:

  • refer to the TV documentation and clarify which formats are supported by the device;
  • search for the necessary information on a specific TV model on the manufacturer’s official website.

Attention! If the technical characteristics of the TV receiver indicate support for the DVB T2 format, this means that the device is capable of receiving ECTV multiplexes. Otherwise, you will need to purchase a special set-top box. A satellite receiver for receiving digital air will not work, since it works with a different format, DVB-S.

Correct connection

There are models of TV receivers and set-top boxes equipped with two different antenna sockets: for receiving terrestrial and satellite signals. For such devices, the correct connection to the signal source is important. We check that the cable from the all-wave terrestrial antenna is connected to the appropriate connector.

The set-top box is connected to the TV using an HDMI cable or tulips. Check that the physical connection is correct and that the correct port is selected on the TV. If you find any deficiencies, you should correct the connection, select the desired signal source (Source button on the remote control).

Reasons for the lack of digital television and how to fix errors

If the automatic start fails to find digital channels, errors may have been made. Why can’t the TV find digital channels when I set it up? This is the most frequently asked question from users when trying to set up a modern TV with many built-in features. Let’s consider the main causes of the problem and how to solve them.

Why does the TV not pick up channels

New technologies make it possible to view central digital television in high quality. With the TV tuner T2, even analog models acquire contrast, clarity of contour and depth of colors. Watching digital channels is possible on TVs of different generations: modern ones are presented with a built-in tuner and allow you to control the equipment with one remote control panel. But it is not always possible to tune equipment for digital broadcasting. Consider situations in which the TV does not find channels.

Why does the TV not pick up digital channels?

Quite a lot of people are faced with such a very unpleasant situation when they buy a new TV, and that one does not catch digital channels. But digital TV broadcasting is the technology of the future, and very soon all TV channels in our country will only switch to this modern format. Do not be alarmed that your TV turned out to be unsuitable for receiving digital television, since most of the problems due to which the TV does not pick up these channels can be eliminated. Let’s consider them in more detail.

  • You are not using a cable or satellite box. Do not worry that without this device you will not be able to watch digital channels. You can, but first you need to find them. To do this, first of all, you need to make sure that the antenna cable is connected to the TV. We go to the TV menu, and select the channel search item, which is usually located in the configuration folder. The TV starts searching for digital channels that need to be added to the analogue channel list.
  • The signal from the antenna may be too weak. You need to purchase another antenna, more powerful.
  • It is possible that your TV does not support the broadcast format adopted in Russia (this happens especially often with TVs that are not intended for the domestic market). In this case, you need to contact specialists who can determine exactly whether it is possible to reflash this TV model so that it can receive Russian digital channels.
  • Your TV does not support the new digital TV format. This is directly related to the fact that the Russian Government decided to postpone the start of broadcasting digital terrestrial TV in the DVB-T2 format to 2012. Thanks to this decision, in those regions of the country where DVB-T2 was not introduced in parallel with DVB-T, but replaced it, TVs of almost all manufacturers stopped receiving digital terrestrial TV. In order to watch TV in DVB-T2 format, you need to purchase an appropriate receiver. However, for example, residents of Moscow were not affected by this problem, since the Moscow authorities found an opportunity to keep broadcasting in DVB-T format in parallel with DVB-T2.
  • Your TV’s firmware is outdated, and even though you can watch digital TV, it cannot cope with this function. To fix the situation, you need to reflash the TV. You can do this both yourself, by downloading the firmware from the manufacturer’s website, and from specialists who repair TVs. Trying to save money at the risk of breaking your TV or trusting professionals is only your business.

In fact, there are a lot of reasons why the TV does not pick up such channels, and we have given only the most common of them. Therefore, if your TV does not want to catch digital channels, then it is best for you to contact the TV Service Center company. This is really the optimal solution, since our masters will help you in any situation, they will carry out accurate diagnostics and eliminate the malfunction of your TV as soon as possible. And you do not need to take your TV anywhere. experts will come to your house.

Software relevance

The DVB T2 format did not immediately emerge as a complete standard. Perhaps the set-top box does not catch digital channels due to the old firmware. How to update the software, you can usually find out on the manufacturer’s website for a specific model, or find instructions and files on thematic forums on the Internet.

The easiest way is for the owners of modern smart TVs: they know how to update themselves via the Internet. If digital TV is not configured, it is enough to check software updates on SmartTV.

Why does the TV not pick up digital channels

What if the TV does not find digital channels, and the antenna is installed by specialists and correctly positioned? If the set-top box or TV does not find it, refuses to receive digital channels, it is possible that a mistake was made when setting it up. All models from different manufacturers, DEXP, SONY, Samsung, LG, Philips and others, have their own specifics of setting parameters. Also, the TV may not receive digital TV through the antenna if it does not have an appropriate tuner.

Is it connected correctly

If the set-top box does not catch digital channels, you should make sure that it is connected correctly. This is especially true for models that have two inputs for an over-the-air antenna and satellite equipment. Make sure the digital TV cable is plugged into the correct jack. The same can be said about TVs that have a pair of inputs for different radio signal sources.

It will not be superfluous to check that the cables are correctly connected between the set-top box and the TV. On the latter, you need to select the connection port. This is usually done with the Source button on the remote control. If the user model has different switching mechanics, you can find out the correct one from the operating instructions for the TV.

Checking and tuning the antenna

In cases where the equipment is not looking for digital channels, it will not be superfluous to check the antenna settings. The recommended procedure is as follows.

  • The condition of the cables is checked. Breakages are eliminated, damaged areas are replaced, cleaned and the connectors are re-tightened.
  • Test tuning of radio or analogue channels to make sure the antenna booster is working properly.
  • If necessary, the position of the antenna can be adjusted. To do this, an information banner is called up on any of the analog channels by pressing the i button on the remote control.

With two indicators of signal strength and quality on the screen, you can begin to push the antenna. They turn it a little. After each position change, you need to pause so that the indicator readings have time to change.

Samsung

On Samsung TVs, manual search is fairly straightforward.

  • You need to go to the on-screen menu.
  • The section Settings. channels is selected.
  • The “Cable” value is set in the signal source selection field.
  • The subsection “Cable parameters” should indicate the beginning of the frequency range of 298 MHz, as well as its end 362 MHz.
  • You should choose which channels to search for: analog, digital, all.
  • Search type must be specified as “Network”.
  • Automatic search starts.

All that is required further is to wait until the end of the process. If the system asks for a password when setting the initial parameters, by default it is 0000. During the scanning of frequencies, a picture of the newly detected channel will appear briefly on the screen.

LG TVs can independently check channel activity and update software. To set up digital TV on models from this manufacturer, you need:

  • go to the on-screen menu;
  • select the “Settings” section;
  • call manual search;
  • select “Cable” as a signal source;
  • set the frequencies in the cable parameters 274 MHz start, 777 MHz;
  • start search and wait for it to end.

Manual Channel Search

The general principle of manual search, if the TV (set-top box) has stopped catching digital channels, is as follows:

  • you need to call the on-screen menu by pressing a button on the remote control;
  • go to the settings section;
  • call the channel setup menu;
  • choose a cable or terrestrial antenna as a signal source;
  • set the frequency range in which the search will be carried out;
  • initiate a frequency scan;
  • wait until the end of the search and save the found channel list.

Let’s take a closer look at how to manually search for channels on TVs of popular brands.

Search setting

Search tuning is often the cause of the issue in question. If the automatic search did not return any results, use the manual one. Do not forget to specify the parameters in the form of connection type, change the country, etc. Use the instructions attached at the beginning of the article.

Cable

Make sure the cable is intact and also check that the connection is correct. If earlier the TV showed channels without interruption, and now it shows no more than 10 broadcasts, then it is likely that preventive work has begun on the side of the provider. Usually, if the cable or inputs are damaged, the telly shows nothing at all.

Equipment

Make sure the connected equipment can receive the broadcast format you want. DVB-T2 is a European digital TV standard that has been adopted in our country. That is, if you cannot use the new format and watch digital broadcast, then your equipment is probably outdated and cannot broadcast the accepted DVB-T2 standard.

Hardware connection problem

Samsung TV won’t pick up digital channels? Check if the connection is correct. Take your time to tune the digit. First, make sure that you have connected all the hardware correctly. For example, a decimeter antenna, implying a built-in amplifier, must be connected to a receiver, which in turn is connected to the TV set itself.

If you have any questions or complaints. please let us know

Transmitter technical problems

The last cause of the malfunction may be hidden on the side of the transmitter, which was the lack of a signal. Then:

  • In the case of cable TV, use a multimeter to check the wiring contacts, including the shield. An open circuit may have occurred between the transmitter and receiver. Make sure the cables are solid and not damaged. As a last resort, call the company that maintains your home and is responsible for providing access to TV broadcasts.
  • When using satellite or terrestrial TV, make sure that there are no problems with the provider. Often on the off-site there is information about scheduled maintenance or possible problems with receiving a signal. Call the operator and clarify the question.

Antenna

One of the common reasons is antenna placement issue. It is necessary to improve the quality of the received signal. But, when using an indoor antenna for digital broadcasting, the image will start to ripple or disappear.

Location and external factors are also important. Place the antenna pointing towards the repeater. Additionally, make sure that there are no obstacles such as tall buildings, trees, etc. If present, move the antenna higher.

How to set up channels correctly

Misconfiguration is often the main reason why channels are not detected. How to tune channels:

  • After connecting the equipment. antenna, set-top box and Wi-Fi adapter, if necessary, turn on the TV and select the type of connection.
  • Open the options and find the item “Broadcast”.
  • Click on “Auto Config” and “Start”.
  • In the next window, specify the cable as the antenna, select digital and analog TV against “Channel type”, which will allow you to search for all types at once. Put “Full” next to the mode.
  • Click on the “Scan” button. this will start a search.

The above instruction is suitable not only for Samsung TVs. It can be used when setting up any TV set. The only difference is in the different names of the menu items.

Why Samsung TV Can’t See Digital Channels: Reasons What to Do?

Samsung TV cannot find digital channels. a common problem among viewers. Most of the problems can be fixed on their own and do not require repair at a service center. But, in order to fix the problem on your own, you need to find out the reason.

How To Rescan Channels On A Samsung TV

Cable

If the previous methods did not help cable TV owners, then study the cable. Check the wire for damage, holes, or other problems. Examine the status of the plugs and input. If only 10 digital television channels are working, then the reason is in technical problems and structural features of the TV. After a few seconds, work will resume.

Why won’t digital channels be tuned in to my Samsung TV?

Not sure why Samsung TV won’t pick up digital channels? First, let’s define the breakdown:

  • Hardware problem. If the TV does not turn on digital channels through the antenna, there is most likely a problem in the wire or receiver. To correct the problem, check the integrity and functionality of the cables, wires and plugs. To check the local antenna coverage, go to the official website http://map.rtrs.rf/ and specify the city of residence. The map will show the broadcasting territory at a specific site or area.
  • Software glitches. Such damage depends on the owner himself. Users may have misidentified the frequency and parameters. Another option is legacy set-top box software. In this situation, you will need to install a new reinstall software.
  • Another reason is preventive work on the TV tower or weather conditions. In such a situation, you will need to wait a little time.

Transmitter technical problems

If the transmitter is broken, contact the service center. The wizard will check for technical problems and fix crashes. It is not recommended to repair the device yourself.

Software glitches

In case of software breakdown, restart the device. Unplug the adapter and reconnect to electricity. Reset all parameters and click on the “Clear” button. Turn on the TV again and check for TV channels.

Customization

Software glitches can be quickly dealt with. First, change the country name to Other. Didn’t the action help? Do a manual search for TV channels, delete all data on the TV or receiver. Update the parameters to factory defaults, and reactivate the search. Try also to update the STB’s firmware.

If you have any questions or complaints. please let us know

Antenna

TV antenna problems are a common cause of no signal on a TV. Install the antenna towards the TV tower. Check that nothing is affecting the signal. If there are obstacles in the way, place the antenna higher.

How to set up channels correctly?

Regardless of the TV model, setup takes place one instruction at a time. The principle of operation is exactly the same. To begin with, there must be a correct antenna that receives a large signal from the TV tower. The device then adds a signal to the menu. After connecting to the adapter, follow these steps:

  • launch the Options menu folder. then click “Broadcast”.
  • Click on the “Automatic Search” section.
  • Activate the “start” key, then select the signal source.
  • When connecting to the antenna, click on the folder with analog and digital channels.
  • Choose one of the options or both.
  • Final stage. activate “scan”.

If your Smart TV device does not include TV channels, then use another method of connecting digital frequencies. Buy a dedicated cable or reinforced box.

External causes

External reasons that do not depend on the user include:

  • technical work on the TV tower, which prevents it from giving a signal;
  • weather;
  • antenna too low power.

As soon as it is possible to find the reason why a person cannot tune digital channels, you can start to eliminate it.

Algorithm for tuning digital channels

Regardless of whether your TV is old or new, the frequency setting is the same. First you need to get an appropriate antenna that can receive a signal. Next, we connect a set-top box for digital television and set up:

Open the “Broadcast” item in the settings;

The TV will ask you to select a signal source. antenna or cable. Choose the one that you have;

Next, you need to select a number or an analogue, or both;

If the device still does not show any picture, use alternative methods of connecting digital television using a cable or satellite box. In the first case, you need to insert a cable from the cable TV into the antenna connector. Then during the settings it is necessary to select not the cable, but “Other operators”. You need to search for both analog and digital channels. Then you can sort and arrange them in the desired sequence.

In the case of a satellite box, two cables are connected. The first is connected to the antenna. Then they connect the equipment to the network and start looking for channels. When a notification of no signal appears, the search will end. After that, the set-top box is connected to the TV with another cable, and a picture appears. In the sections “Quality” and “Strength” you can adjust the image.

Software glitches

Failure in the program most often happens through the fault of the user. During the settings, the parameters could be entered incorrectly or the frequency was entered by mistake. Perhaps the old STB software is not supported by the developer. In this case, you need to reinstall the software on the digital set-top box.

Reasons for the absence of digital TV channels and their elimination

If, after autosearch, the TV does not catch channels, then the device has problems. Malfunctions can be in the signal reception, in the connection method, in the settings or in the equipment itself. In order to eliminate the cause, you need to find the problem. How to do it and fix everything, read below.

Toshiba

Toshiba is tuned in the same way as previous models. In the country settings, select Germany and the input is “Cable”. Next, go down to automatic configuration and click OK. In the pop-up window, select the “DTV” mode, and then set the parameters: for the initial frequency. 274,000 KHz, for the final. 770,000 KHz. Confirm your selection and setup will begin.

Samsung TV does not find digital channels

Samsung TV can’t find digital channels? Do not rush to carry the TV for repair, perhaps the cause of such a problem is much easier to fix than you think. Digital television allows you to get images with high resolution and improved color reproduction and contrast, however, digital broadcasting is not always connected without errors.

Reasons why Samsung TV does not see digital channels

Antenna autosearch often gives a large list of digital TV channels. If your device did not find any, there may be several reasons:

  • incorrectly selected antenna type;
  • incorrect installation of the antenna;

These two reasons are solved manually at home. Instructions are supplied to the antenna and TV without fail, in which you can find recommendations on the correct installation and tuning of the antenna and the search for channels.

How to set up a Samsung TV

Setting up digital TV channels on Samsung TVs follows the same scheme, regardless of the model. To connect, you must have a special antenna designed to receive digital TV signals. If configured correctly, the adapter receives a signal from the antenna and adds the “Digital TV” item to the menu.

To connect a digit to your TV, repeat the following steps:

  • Open the settings, select “Broadcast”;
  • Select automatic search and click the “Start” button;
  • A message will appear on the screen asking you to select the signal transmission tool. cable or antenna. Choose the second option;
  • Next, the device will give you two types of channels for searching: digital, analog or both types at once.
  • At the end, turn on “scanning”. the system will start searching for all possible channels specified in the search.

If the antenna does not pick up enough channels or does not pick up channels at all, try to connect using an alternative method. via a cable or a third-party device, such as a satellite repeater. In the first case, you need to connect a cable to the antenna, and in the settings menu, select the item “other operators”, select the “full” package. this will allow you to choose digital channels among all available.

How to fix the problem

The entire process of tuning and adjusting the search for digital channels can be obtained from the instructions for your antenna or by contacting your service provider. Here are some tips to help you improve your channel search regardless of your TV and antenna model:

  • in the “Country” field write the symbol “-”;
  • add new frequencies manually;
  • check the antenna on another TV;

reset the device to factory settings or update the software version.

Antenna location problem

Let’s say the hardware is of the correct standards, and the TV or set-top box can’t find channels. The second most important reason may be incorrect installation of the antenna or interference clogging the receive channel.

    Digital antennas are very sensitive to the direction of reception: for a satellite, sometimes even a few degrees is already a critical error. The directional pattern of terrestrial terrestrial antennas is such that they work more reliably when they are directed with their axis to the source of the decimeter signal. Therefore, when installing, the antenna must be tuned in the direction of the satellite or repeater.

If the problem lies in this area, proceed in accordance with the instructions for installing terrestrial digital TV antennas.

Equipment selection

One of the simplest reasons why autosearch does not find channels may be a mismatch in standards.

Before the decision was made at the federal level to transfer Russian television to digital, there was already experimental broadcasting, and often it was carried out in the old European DVB-T format. Therefore, if the equipment does not support DVB-T2, it may simply be outdated.

A similar situation can be with cable and satellite broadcasting. They also use the standards of the DVB group for reception, only with additional letters C (from the word “cable”. “cable”) or S (from “satellite”. “satellite”). There, too, there may be additional numbers 2: the second generation standards have already been developed and are actively used.

Software glitches

Another problem is configuration failures. Decoding a digital signal requires the tuner to confidently perform a specific algorithm. And if it is violated, there is no need to talk about the playback of audio and video information.

Here’s what to do to fix this problem:

  • re-catch the TV signal. To do this, you need to reset the tuner settings (built-in or set-top box) to factory settings and re-search for digital TV channels;
  • download new firmware for your TV or set-top box;
  • update your satellite TV access card if you are using a device with pay TV channels.

In practice, re-tuning for terrestrial television usually looks like this:

  • The set-top box connects to the antenna and TV.
  • The operability of the connection is checked: when the “Menu” function is activated, the STB settings should appear on the screen. If this does not happen, you need to check if the receiver is connected to the TV receiver correctly.
  • The setup function is activated in the menu. Usually it is located under the item “Channels”, “Broadcast” or similar.
  • Autosearch is activated. Exactly how this works depends on the specific set-top box. Here you need to read the user manual. At the end of the autosearch, its results are recorded in the memory of the STB.
  • If the automatic range scan does not produce any results, a manual search for TV channels is performed. In this case, it is necessary to set the limits within which the scanning will be carried out, and further guide the search process. How exactly this should be done depends on the design of the receiving device. You need to use the operating instructions, and read it in advance, before the setup process.

What to do if the TV does not catch digital TV channels: step by step instructions

A fairly common problem when setting up a TV is that the TV does not find digital channels. There can be many reasons for this, so it is important to check and discard possible causes step by step until you get to the bottom of it. Cases when a seemingly serviceable TV receiver has stopped catching channels can be disassembled according to the same scheme. We tell you exactly how to act. from simple to complex.

Hardware connection problem

Another source of problems in the operation of a digital set-top box or TV with a built-in tuner is incorrect connection of receiving devices.

    For connection, a cable with a characteristic impedance of 75 Ohm must be used. almost all devices from the receiver to the TV itself are designed for it. The wire must provide normal transmission, therefore, the rules regarding signal attenuation must be observed.

Transmitter technical problems

Finally, if the receiving equipment is configured normally and functions within the technical limits established for it by the manufacturer, it can be argued with a high degree of probability that there are problems on the transmitting side. One of the multiplexes may be disabled on a repeater closest to you for technical reasons.

In this case, the problem must be solved as follows:

  • If we are talking about cable television, then it is necessary to “ring” with a multimeter all the wiring contacts both within the boundaries of the apartment and outside it, right up to the switchboard. It is possible that there is a break in the route between the transmitting cable station and the receiving device. If there are problems inside the apartment, you need to fix them by re-soldering or replacing the wiring cables. If everything is normal inside, but there is no signal in the shield, you should file a claim with the organization that serves a particular house and provides access to the broadcast of the cable operator.
  • If you have problems with receiving a signal from a satellite or terrestrial operator, you need to check if he has any problems with transmission. As a rule, on the official website of the RTRS, information such as is posted: “In the period from X to Y number in such and such a territory, there may be interruptions in the reception of TV channels.” Then you just have to wait until the technical difficulties are resolved. If such problems are not reported on your territory, find the nearest repeater to you on the CETV map, click on it, copy the name of the LLC serving the tower, and then paste it into the search engine. So you will find their telephone on duty, which you can call and clarify about the presence of problems.
