The TV does not pick up digital channels through the antenna

Table of Contents

Antenna

Antenna misalignment is considered a common problem. Go to the official website. www SIM card.rtrs.rf /. In the search box, enter your place of residence and see the location of the nearest TV towers. Point the antenna towards the repeater.

Also, do not use indoor type antennas for picking up “numbers”. Otherwise, the image will ripple, disappear, or be of poor quality. Additionally, look for interference such as tall trees, buildings, etc. You may need to place it a little higher.

Why LG TV Won’t Find Terrestrial Digital Channels: Reasons What To Do?

In 2021, a TV is available in every apartment. If earlier simple devices were popular, now models with Smart TV technology are mainly used. But, sometimes the technique in question fails. What to do if LG TV cannot find digital channels? In the article, we will study the procedure for searching for TV broadcasts, consider common mistakes and solutions.

Transmitter technical problems

The next reason is on the transmitter side. The absence of a signal can be corrected in two ways:

  • If using cable TV, use a multimeter and check all the contacts, right down to the shield. You may need to contact a company to troubleshoot a problem that maintains your home and provides access to television.
  • Do you use satellite or terrestrial television? Contact your provider. Probably, planned technical work is underway or an accident has occurred due to weather conditions, which is already being corrected by specialists. Visit the official website of the operator, usually there they always update information and notify customers about preventive maintenance.

Cable

Does the device only detect analogue channels? Check cable and inputs for continuity. If the TV set does not find broadcasts, then first of all you need to check the cables. Everything is fine? We look at the following reasons.

If you have any questions or complaints. let us know

Search setting

It is important to specify the search parameters correctly. Earlier in this article, we covered the procedure for setting up a search. Use the instructions. One solution is to change the country.

Hardware connection problem

Incorrect equipment connection is one of the common problems. Before carrying out the adjustment, make sure that the equipment is connected correctly. For example, a decimeter antenna, which immediately implies a built-in amplifier for improved signal reception, is connected first to the receiver and then to the TV. And in the presence of cable TV, the wire is connected to a specific input of the receiver.

Equipment

The equipment is connected first. Make sure you have followed this procedure correctly. Also check if it supports the required DVB-T2 broadcast format. Previously, this standard was not available in Russia, it was borrowed from Europe, and is used to watch digital TV. Outdated equipment will not be able to receive the desired DVB signal.

Philips

In older models, the setting is as follows: press “Home” and select “Configuration”. Then go to “Settings” and select the channel setup. In the window that appears, select “Automatic installations”. To save everything found, you must click “Reinstall”. Choose a country.

It is better to install European countries, otherwise you will have to contact specialists to install new software.

Then go to “Digital mode” and select the cable as a signal source. In the new window, click “Automatic search”. Then click “Start” and wait. Sometimes during the process, the device may ask for a password. Try entering four zeros, four ones, or 1234.

The setup process is slightly different on modern models. In the “Installation” item, select “Search for channels”, then “Reinstall”. Select your country and digitally select “DVB-C Cable”. Next, the device will ask you to enter the network frequency or baud rate. Enter 6.750. And then select “Quick” or “Full” search. In the first case, you will have to wait no more than 10 minutes, and in the second. about 30 minutes, but it will find more channels. With a quick search, you will need to enter the value of the frequency drop. 8 MHz. At full set QAM to 256 and frequency to 298.00.

Running a Channel Scan with a TV Antenna? Avoid This Common Mistake

Methods for receiving digital TV channels

There are several ways to catch a figure:

The signal for terrestrial TV is distributed using terrestrial repeater towers. In order to receive it, you need an antenna. Using this technology, the image is transmitted free of charge. But with this method, the TV often does not pick up the signal well. Since the quality of the picture is affected by where the tower is located, what the weather is outside, and many other factors.

Apartment buildings are most often used by cable TV. In this case, the signal is transmitted through a cable that is connected to a common antenna. However, it must be paid for and cannot be used in private homes. Satellite signal transmission is carried out by satellites, and it is received by a special dish. This method allows you to receive the largest number of channels. But you have to pay for it and buy additional special equipment.

Of all these methods of receiving numbers, on-air is the cheapest and most widely available. But the picture quality is poor.

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.

How digital television works

Digital TV works on the principle of transmitting images and sounds through compressed coded signals. Exactly the same technology is used to transmit a signal to a computer. This allows you to get better picture and sound quality, no interference can affect it. In addition, more channels can be transmitted in this way, and users are able to access the Internet directly from the TV.

Antenna

Antenna problems are the most common reason why TVs won’t pick up digital channels.

Do not use an indoor antenna for digital reception. Otherwise, the picture will constantly disappear or it will be completely bad.

Try pointing the antenna towards the tower. Make sure nothing is interfering with the signal. no trees, buildings, etc. If there are obstacles, lift the device higher.

Customization

Software problems can be easily dealt with. First, try changing your country to Other. If this does not help, perform a manual channel search, reset the TV or receiver to factory settings and search again or update the set-top box firmware. If after that the TV still does not find channels, then look for the problem further.

Samsung

If you have a Samsung TV, go to the menu, in the “Channel” item, select the cable. For Country, enter four zeros and set the country. In the “Cable parameters” section, set: “Start Frequency”. 298,000 KHz, “End Frequency”. 362,000 KHz. Do not touch the rest. In autotuning, select a digital or analogue. In the search mode, press the network and wait until the picture appears. They can be removed from the list. To do this, in the “Channels” item you need to go to the “Dispatcher” and select which ones you want to delete.

If you own an LG TV, go to the menu or press the Home button (for Smart-TV). In the options, select the country, then in the settings, click “Autosearch”. In the window that opens, select the type of signal. And then set the data of the start frequency to 274,000 KHz, and the end frequency to 770,000 KHz. Then run a search. In the cable settings, you can set auto-update, which will be regularly carried out without your participation.

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.

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 the 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.

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).

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 attachment. A satellite receiver for receiving digital air will not work, since it works with a different format, DVB-S.

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.

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 analogue 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.

does, pick, digital, channels, antenna

Setting the signal quality from the antenna

Problems with missing digital channels may be related to antenna alignment. Fault diagnosis is carried out step by step.

  • Check the condition of the connecting cable and contacts. If you find cable jams, damaged areas and poor connection, you should eliminate the shortcomings.
  • Ensure that the signal amplifier is working properly by test tuning the radio and TV signals.
  • Adjust the position of the antenna with small turns for the best signal strength and quality indicators. 70% and above.

If all the hardware elements are present and the connection is correct, the digital channels will be set up without problems using the settings menu sections. The tuning algorithm for specific brands is detailed in articles about Samsung and Philips TVs.

Checking TV and set-top boxes

There are two well-defined groups of digital TV subscribers. Some watch channels through a set-top box, while others have a modern TV with a tuner that supports the DVB T2 broadcasting format. Therefore, you should make sure not only of the correct connection of your equipment, but also of its ability to reproduce digital broadcasting channels.

It is quite simple to check if the set-top box or TV accepts digital channels.

  • You can see in the operating instructions of the model which broadcast formats it supports.
  • Information about the device is easy to find on the Internet or on the manufacturer’s official website.

Sony bravia

On Sony Bravia TVs, you can select digital TV (antenna) as the signal source. The setup process looks like this:

  • the on-screen menu is called up;
  • a transition is made to the system settings;
  • select the item channel setup;
  • “Digital TV Antenna” is selected as the signal source;
  • the provider name parameter is set to “Others”;
  • the frequency of the first multiplex is set.

After searching, the list of found channels is saved. Then the operation is repeated for the second multiplex.

Advice! Frequencies can be found on the interactive map by visiting the resource rtrs.ru.

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.

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 briefly appear 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.

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.

Checking the coverage

Next, what you need to pay attention to is the coverage. Is there a TV tower in your area and does it cover your area? In general, if you live in Russia (and not far in the taiga ), then you are almost certainly in the digital TV coverage area.

You can find out which channels are broadcast in your area on the official website: https://rtrs.ru/. Note: in the top menu you will need to select your area.

What channels are broadcast in my area

By the way, in the same place on the site you can see a map on which the towers and the zones they cover are marked.

Does TV support digital TV

In order for the TV to receive digital channels, it must support the DVB-T2 standard. If your TV is 2017-2019, then it 100% supports this technology.

In general, to find out for sure. you need to clarify the TV model and watch its tech. characteristics. This can be done, for example, on the Yandex Market.

By the way, if it turned out that your TV does not support the DVB-T2 standard (i.e. it cannot receive digital broadcasting), then you can proceed as follows:

  • or purchase specials for TV. an attachment that supports this standard (issue price from 700 rubles). Such a set-top box will be like an “intermediary” between the TV and the antenna;
  • either connect to cable / satellite television (all equipment is provided and configured when connected by the operator, so there is no point in puzzling your own head );
  • or replace TV with a newer one.

Antenna and television cable integrity

The same antenna can be used to receive digital channels as for tax television. True, I would immediately note one important thing: if you do not live in a large city, you may need to think about an antenna with an active amplifier.

As for the integrity of the cable: check for twists, deformations, knots, etc. Often, the cable is gnawed by pets.

Of course, the safest way is to go independently from the antenna to the TV, looking through every centimeter of the cable. If there is any twist on the cable. it is better to replace the entire cable (if this is not possible, use the F-socket to connect the broken cable, see the screen below).

In addition, it is recommended not to use various twin-tees, etc. (they can cause a variety of interference and no signal). At least disable them for the duration of the diagnostics.

About types of broadcasting

The article should start with a couple of words about the types of broadcasting (so that further it is clear what it is about). Depending on the method of reception, there are three options for viewing the “numbers”:

  • On-air broadcasting: with this method, you simply connect a regular antenna to the TV and catch 20 free channels from the nearest TV tower. It is the solution to the problem of receiving broadcasting that will be considered further in the article!
  • Cable TV: This method can be divided into several other options. In general, your TV is connected to a special cable via a regular cable. the operator’s server, which broadcasts the channels. As a rule, the number of TV channels with this method is much higher: 50-100;
  • Satellite broadcasts: as the name suggests, a dish-shaped antenna is used for connection, to which the signal from the satellite is received.

Actually, if you have a problem with cable or satellite TV, then this note will hardly help you (the fact is that there are many operators, there are even more ways to connect, and it is unrealistic to consider all this in one note.).

The TV does not find digital channels. what to look for!

Good day!

Due to the widespread transition to digital broadcasting, today’s question is far from uncommon, and over the summer I received dozens of them.

If we somehow classify and distribute them into subgroups: then in 90% of cases the inability to catch a “digit” is associated with an antenna, cable, incorrect TV setting (and only in the remaining 5-10% the question is much deeper: firmware, equipment malfunction, etc. ).

Actually, in this article I have collected these variants of problems together (so that anyone can “go over” them before calling the master and spending money on it.).

Antenna location

In addition to the type of antenna, its location is of great importance to the reception quality. For example, even an ordinary indoor antenna, if you move it around the apartment, can give completely different reception quality (for example, in the bedroom by the window. TV will receive the “digital” perfectly, but in the hall, not very well).

  • an indoor antenna almost always loses to an outdoor (outdoor) antenna;
  • an antenna with an amplifier (as a rule) is better than without it (by the way, amplifiers can be active and passive. the first type wins significantly!);
  • if the antenna is below the level of nearby buildings, trees, it will be much worse to catch (see the picture below).

Those. A short note of the above is: try placing the antenna in a different room. If you live in a private house and far from the TV tower, while there are trees and other buildings in the environment, try to place the antenna on the roof (even better, raise it above the level of the trees, see the photo below).

Antenna above the level of plantings and buildings

What to do if the TV does not find digital channels

Correct channel setup

And so, the antenna is checked, the cable is connected, amplify it works (if any), go to the TV setting.

After going to the settings and choosing the auto-search for channels, pay attention to the checkbox next to the broadcasting (how it looks on TV from LG is shown in the photo below). Many people cannot find digital channels just because of this “little thing”.

In addition, some TVs have the ability to specify the type of antenna connected. Of course, choose the option: regular, street. In general, then, after 3-5 minutes. after scanning, TV should find 10-20 TV channels.

In some cases, the problem with the reception of “numbers” may lie in the firmware (TV software). After updating it, often the TV started to work normally (be careful with the firmware.there is a possibility of disabling the TV).

Note: how to update the firmware is usually always indicated on the official TV website. For example, Samsung has this information on this page, LG. here.

If you have resolved the issue in some other way. let me know in the comments (thanks in advance).

Antenna

Antenna problems are the most common reason why TVs won’t pick up digital channels.

Do not use an indoor antenna for digital reception. Otherwise, the picture will constantly disappear or it will be completely bad.

Try pointing the antenna towards the tower. Make sure nothing is interfering with the signal. no trees, buildings, etc. If there are obstacles, lift the device higher.

Cable

If the above did not help cable TV owners and the TV channels only show analog, check if everything is in order with the cable. Inspect it for damage, if everything is in order with the plugs and connections. First of all, you need to check the cable if everything was fine before, and then the TV stopped showing channels. If you only have 10 digital channels, then the reason most likely lies in the technical work and the peculiarities of the functioning of digital television. Sometimes you just have to wait and everything will return, and sometimes you just need to search for channels again.

The TV stopped catching digital channels through the antenna

Good day!

Due to the widespread transition to digital broadcasting, today’s question is far from uncommon, and over the summer I received dozens of them.

Actually, in this article I have collected these variants of problems together (so that anyone can “go over” them before calling the master and spending money on 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. Then we connect the 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 the 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.

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.

Reasons for the lack of channels

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.

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.

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, experimental on-air broadcasting was already being carried out, 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.

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.

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.

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.
