The TV stopped showing Samsung digital channels. The TV does not pick up channels: what to do?

Today, many people are faced with the problem of disappearing television channels. If you are one of them, then do not rush to call a professional to your home, since the reason why they disappeared can often be eliminated yourself. In this article we will tell you why the channels disappeared and how to solve this problem.

If satellite channels are missing

So, if previously your satellite television showed channels normally and suddenly stopped doing so, in this case two categories of reasons can be distinguished - problems with the equipment itself and problems associated with the program. Among the latter, the following main reasons can be noted.

• Missing channels Interactive services do not work.
• The picture splits, freezes, or appears as a pixel.
• Picture and sound are out of sync.
• Subtitles are missing or not displaying correctly.

Manual retune is often confused with "automatic retune" as it appears to be a similar function since you physically press a button on the remote control to do it. With "manual tuning" you need to enter and store the corresponding channel numbers or frequencies from the correct transmitter yourself, one at a time. However, with automatic tuning, the equipment selects a transmitter for you, and it may not be the one your antenna points to.

Remember that the TV remote control itself is not capable of turning on channels related to satellite television. This must be done using the receiver's remote control. Therefore, you should set your TV remote to AV mode to be able to change the settings of your satellite TV and see its channels.

It will continue to tune up through the high channels until it reaches channel 68 and then stop. The problem in some areas is that the signal may be better on higher channels. However, the set is not smart enough to skip lower channels when auto-tuning. So if it finds a signal even weak, it saves the channel and continues tuning, ignoring any other available channels that may have a better signal. That's why we tell you that you enter the channels, one by one manually, so ignore the weaker channel numbers and just enter the ones you need.

Coded channels

If you see “Scrambled Channel,” it means that particular channel is not included in your current satellite TV channel package. Through the provider's website and its control panel, you can purchase the channel you need. In addition, this situation may be due to non-payment. That is, it is likely that the package you paid for has expired. If you pay for a channel, it must be turned on within a day from the date of payment.

Why us?

How to find channel numbers. Before you begin manual tuning, you need to know which transmitter your antenna belongs to and the channel numbers that are used by that transmitter. This will give you a list of transmitters for your location. Select your transmitter on the left side, then select "Quick Setup Tips" and "Download Reset Guide."

Didn't manual configuration help me now? If you still have a problem after manually retuning, it may be because your receiver still has the wrong channels stored in its memory. There are two ways to clear memory. Perform a "factory reset" from the setup menu as described in your manufacturer's instruction manual. Sometimes manufacturers refer to this as "first installation" or "delivery condition". This will clear your settings.

Incorrect settings

To search for channels again, you can reset the settings. This is done using both the remote control and the receiver. You can press the power off button on it and then turn it on again, or you can try removing the card and inserting it again. However, you should know that this action is usually carried out in extreme cases. In addition, pay attention to the choice of your region and indicate it correctly.

Perform automatic re-tuning by removing the antenna wire. This will clear the memory and remove unwanted saved channels. The air wire must then be reinserted and manually adjusted to readjust again. If you have difficulty with this operation, you should seek help.

If you decide to use a professional, it is recommended that you use a qualified installer. We cannot recommend individual installers, but you may wish to seek advice from recognized industry bodies such as the Aircraft Industry Confederation.

It is also recommended to check the serviceability of the receiver: if the indicator light does not light up, then most likely the problem is either in it or in the wires to which no current is supplied. Channels may also disappear due to damage to the satellite dish or severe weather.

If digital channels are missing

When you suddenly lose channels on your digital television, you can fix the situation using the following methods:

This guide to these channels includes help for those who are having trouble receiving some or all of the new offers. It shows exactly the same content as this channel, but with better picture and sound quality. In the southern Sunshine Coast and Toowoomba regions, the channel is broadcast on digital channel 66. The channel broadcasts food and cooking programs from cultures around the world.

Turning on via TV remote control

The high definition channel broadcasts on channel 31 and has the same programming as the standard definition channel on the channel. In almost all cases, you will need to retune your TV or VCR or higher-end device to receive these channels correctly. This means follow the instructions that came with your TV or equipment. The rest of this guide assumes that you have followed the manufacturer's instructions for this procedure.

• Check what mode your TV is in. It must be in the socket mode to which the wires from the television receiver or AV are connected.
• Make sure you are performing operations using the receiver's remote control and not the TV itself. It is with this remote control that you should tune and change channels.
• In the TV menu, try auto-searching for channels again. If not all channels are displayed, you need to do a manual search and catch even weak signals, which is impossible to do with auto search. If the reason is weak signals, you will need an amplifier or antenna relocation.
• Check whether your digital television is paid for on the provider's website.
• Check the wires and their connections to the correct sockets, and also make sure that the card is inserted correctly.
• Check the antenna for serviceability and correct connection, then repeat the auto search.

There are four main factors that affect the results of retuning and whether you can receive these new channels. Where do you live? See the table below. It shows which channels can be received in different regions. Channels with blue highlighted boxes can be received on all TVs.

Detailed information for old equipment

Below is a step-by-step guide to setting up your old hardware. If you don't, you'll need to double-check your TV's setup instructions and try again. Select and view this channel if possible. Note. A limited number of models may be compatible, but there is an option to disable it. Some other brands may have similar settings in the settings menu.

The TV does not see the antenna - what to do? Troubleshooting does not give an answer, and the equipment seems to be new, but there is still no signal. This problem usually occurs either with a new TV or after turning it on. The situation is unpleasant, and in 90% of cases you cannot do without a specialist.

There are 4 main cases when the TV does not see the antenna.

There is no information on when all stations will resume broadcasting at this stage. At this stage there is no information about other services. If you plan to watch only over-the-air, then just turn on the TV. Press the channel button on the remote control as if you were trying to change the channel. A menu will appear to initialize channel search; if not, press the Menu button on your remote control and then select Channel Search from the available options.

Automatic mode will automatically detect how you receive TV and search for stations, programming them as they arrive. Do not disrupt the channel search process. On many models, the TV will automatically switch between menus and programming when the search is complete.

1. After searching for a new TV, it displays the message “channels not found.” LG, Samsung and other new models with complex settings especially often do not see the antenna. How to react?
   • Check that the antenna plug is firmly inserted.
   • Make sure the plug is inserted into the correct socket.
   • Search is not configured correctly. In modern TVs, there is a separate search for terrestrial and cable TV.
   • Check the TV's functionality using the included antenna. If channels are still not found, the problem is with the TV itself.
2. The provider is to blame. If you use satellite TV services, the provider may have problems or the subscription fee was not paid on time. Call your operator and find out.
3. The socket is damaged and the TV cannot receive any signals. To make sure, try searching for channels not only on the airwaves, but also on the cable frequency. If the signal is not detected and the antenna cables are in order, the problem is either in the antenna itself or in the socket where the plug is inserted. Repairing such a malfunction is a jewelry job that only a qualified craftsman is allowed to do.
4. The tuner is damaged. Any breakdown in one of its nodes leads to deterioration or loss of the signal. For repairs you need to call a specialist.

What to do if the TV does not see the antenna?

In the first two cases we examined, you simply need to solve problems with the provider or the store where you bought the TV. If there is a malfunction inside the TV, tuner or antenna, you cannot do without calling a technician.

Try switching through channels using your remote control. If you don't get all the channels you expected, check to make sure you've connected your cable or satellite receiver securely to your TV and try scanning for channels again.

The new technology is also changing transmission channels - even with new devices that have already been trialled. For each receiver, be it a TV or set-top box, you need to run a search for a transmitter. To search, you need to open the menu using the receiver's remote control. Other steps and names vary depending on the model. For example, select Install. Then run "automatic transmitter search". The device now searches for all available stations.

Quite a lot of people are faced with this very unpleasant situation when they purchase a new TV, but it does not pick up digital channels. But digital television broadcasting is the technology of the future, and very soon all television channels in our country will switch only to this modern format. Don't be alarmed that your TV is unsuitable for receiving digital television, since most of the problems that cause your TV to not pick up these channels can be fixed. Let's take a closer look at them.

• You are not using a cable or satellite box. Don't worry that you won't be able to watch digital channels without this device. You can, but you need to find them first. To do this, you first 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 begins searching for digital channels that need to be added to the list of channels in addition to analogue ones.
• It is possible that the signal from the antenna is too weak. You need to purchase another antenna, more powerful.
• It is possible that your TV does not support the broadcast format accepted in Russia (this especially often happens with TVs not intended for the domestic market). In this case, you need to contact specialists who can accurately determine 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 television 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, televisions from almost all manufacturers stopped receiving digital terrestrial TV. In order to watch television 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 maintain broadcasting in the DVB-T format in parallel with DVB-T2.
• The firmware of your TV is outdated, and even though it has the ability to watch digital television, it cannot cope with this function. To correct the situation, you need to reflash the TV. You can do this either yourself by downloading the firmware from the manufacturer’s website, or from specialists who repair TVs. Trying to save money at the risk of breaking your TV or trusting professionals is up to you.

In fact, there are many 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 pick up digital channels, then it is best for you to contact the TV Service Center company. This is truly the optimal solution, since our technicians will help you in any situation, they will carry out an accurate diagnosis and fix the malfunction of your TV in the shortest possible time. Moreover, you don’t need to take your TV anywhere - specialists will come to your home.

As sad as it may be, everyone has unpleasant situations when the TV stops working, namely, it does not see the antenna or loses the cable connection. There can be many reasons for this behavior of equipment, let's look at the most common ones.

• The new TV that just arrived from the store does not respond to the antenna cable at all. The reason for this may be a break in the cable itself, but you need to make sure of this. You can check the TV using an indoor antenna, which is present in almost all TVs; if there is a signal, then the reason is really in the wire. If the signal does not appear, then it would be best to return the TV under warranty.
• The TV does not find any cable channels. If your TV previously worked perfectly from a regular antenna, then the cause may be incorrect frequency detection settings. Cable channels are specially broadcast on a different frequency, this is done for convenience, so that people do not get confused in their diversity. Your instructions should indicate how you can change the settings from DVB-T (regular antenna) to DVB-C (cable television). The second reason for this problem may be technical problems that have arisen with the provider, so you need to call the hot number and find out if everything is fine with the cable television service provider.
• The TV has stopped receiving signals from both cable and regular television; the antenna cables are working properly. The problem may be with the TV's antenna socket, which could be faulty. The reason for this may be the burnout of individual parts of the microcircuit (diodes, capacitors, etc.); such a breakdown cannot be repaired independently.
• Under various circumstances, the tuner that connects the antenna cable and the television receiver may fail. Antenna sockets and other components could become loose or damaged. To correct such a defect, you must contact a television technician. It is highly undesirable to engage in “self-medication” in such a situation.

There are many other problems associated with the loss of a signal from a television or cable antenna, but the vast majority of such breakdowns and defects require the professional intervention of a TV technician, so the easiest way would be to call specialists from the TV Service Center company. Our specialists quickly respond to your request, have all the necessary tools, as well as extensive practical experience, which allows you to quickly, efficiently and inexpensively fix any TV breakdown right in your home.

Today, more and more people prefer digital television to analogue. 20 channels are available for free use, featuring high image quality and good sound. To broadcast digitally, almost all modern television panels are equipped with a built-in DVB-T2 tuner, and for older television receivers you can purchase and connect a digital set-top box. But sometimes channels may not be displayed at all or only analog channels may be broadcast. This can happen both when setting up equipment, and spontaneously for no apparent reason. To understand why the TV does not find digital channels, and what to do in this situation, you need to understand the principles of operation of such television and the procedure for setting up the equipment for reception. Read more about possible problems that may arise during the connection process and methods for eliminating them in the material below.

How digital television works

Digital television is the latest technology that provides excellent picture and sound quality, and also offers more TV programs and additional features, for example, interactive TV, video on user request, subtitles, blocking of certain TV channels, electronic guide. The principle of operation is simple: the encoded audio and video signal is transmitted over radio frequencies in the form of a stream similar to that received on a PC when watching videos on the Internet.

Thanks to compression and a digital algorithm, it became possible to send a much larger number of TV channels and radio stations than was possible on analogue television. Another advantage of digital TV is immunity to interference and absence of stripes, blurry images of low quality. The TV either displays a good image or has no image at all.

On a note! In some cases, when broadcasting, the video may crumble into squares, sometimes disappear and appear again after some time. This is related to the operation of the antenna and is eliminated after tuning it, replacing it, or installing an amplifier.

Methods for receiving digital TV channels

Today there are several ways to receive digital channels:

• ethereal;
• cable;
• satellite.

Signal for etherealTV distributed by terrestrial repeater towers. To receive it, you can use an outdoor or indoor antenna. This is an absolutely free method, but the signal to the user is often weak. Its intensity depends on the location of the tower, weather conditions or other factors.

Cable TV found in apartment buildings. In this case, the signal is transmitted through a cable coming from a common collective antenna. Such services are provided by the operator RTS Telecom, MTS, TTK, as well as other companies. Disadvantages include limited availability (this type of television is usually not applicable for private homes) and subscription fees.

For satelliteTV the signal is broadcast from satellites, and reception is carried out through a special dish. This method ensures reception of the largest number of TV channels. Disadvantages include annual or monthly fees and the need to purchase special equipment.

Thus, the least expensive, simple and accessible way to receive digital television is to install and configure an over-the-air antenna. In order to receive a stable signal, the user, in addition to the antenna, will need a digital DVB-T2 receiver, which are produced by BBK, Supra, D-Color, Rolsen and others. Many modern TVs already have a built-in digital tuner, as you can verify by looking at the device specifications in the user manual. In this case, you will not need to purchase an additional receiver. An ordinary analog antenna can be used for reception, it all depends on the signal level and the distance of the tower.

On a note! The list of free TV channels for 2018 is divided into two multiplexes operating on different frequencies and channels, which vary depending on the region. A total of 20 television channels and three radio stations are available for viewing.

Reasons for the lack of digital TV channels and their elimination

If the user installed an over-the-air antenna, launched an auto search, but the TV did not find any channels, this indicates problems: with signal reception (that is, with an antenna), with the method of connecting equipment, with settings or with the devices themselves. How to diagnose and eliminate the cause is in the material below.

Antenna

First of all, you should pay attention to the antenna. If HF antennas are used to receive an analog signal, then . UHF antennas are more compact, but they often offer combined devices that are suitable for receiving different bands. From such antennas you can remove the long structural elements that are necessary to receive a meter signal, and then you will get a good, compact, small-sized decimeter device.

Some users, instead of a decimeter antenna, install a Polish one (or “grid”), which is inexpensive. It is also suitable for digital signal reception, but in some cases (depending on the installation location) it may be necessary to dismantling the amplifier. There is a high probability of this if the tower is nearby - then turning on the amplifier can lead to the disappearance of a very strong signal.

Advice! It is not recommended to use an indoor antenna to receive digital television, since a positive result is only possible in areas with a very good signal. Otherwise, the user may encounter the fact that the found channels will regularly disappear, and the image will crumble into squares and often freeze.

To receive digital channels reliably, the antenna must be installed correctly. It must be directed towards the tower (you should focus on the direction of the antennas from neighboring houses/apartments), and there should be no obstacles in front of the device - trees, buildings, etc., for which it is advisable to raise it as high as possible.

Settings

In addition to the antenna, software problems can also cause the lack of digital TV channels. To fix them, you need to do one of the following:

• when searching for TV channels, set the “Country” field to “Other”;
• search for channels manually;
• reset the TV (if the tuner is built-in) or the receiver (if an external device is used) to factory settings and search for TV channels again;
• update the firmware of the set-top box.

If the action taken does not bring a positive result, all of the above should be carried out sequentially.

If manipulations carried out with the antenna or device settings do not eliminate the problem, it is worth checking the cable - it may be broken or burned out. You also need inspect the plug and connections- the contact may disappear at the site of one of the twists.

Advice! Checking the plugs, connectors and cables should be done first if the TV was previously working properly, but suddenly stopped showing TV channels.

To exclude a malfunction of the TV, you need search for channels on it using a different antenna, obviously working. Next, with the TV channels configured, you need to connect it to your own antenna and in this way look for the problem. If the user’s actions are effective, that is, an image appears on the turned on TV with the antenna cable connected, then you will have to purchase a new antenna or cable. Otherwise, you will need to contact a telemaster.

General procedure for setting up digital channels

You can configure your TV or receiver to receive digital TV channels automatically or manually. The first method is used in case of reliable signal reception, the second - in case of unstable stream or in a situation where the TV does not see channels through auto search.

Yes, to start automatic search you need to plug in the TV, connect the antenna or receiver and start detecting digital channels, then wait for the process to finish and save the result.

If the TV does not receive channels in automatic mode, you can start manual search. To do this, you will need to know information about the channels and frequencies on which the signal of each multiplex in the user's region is transmitted. In the TV menu, select the desired mode, enter these parameters and start the search. At the end of the process, the result should be saved.

Features of setting up television receivers of some brands

On TVs from different manufacturers, digital channel settings are performed differently. Below are the setup methods using the most popular brands as an example.

LG

The process of setting up digital channels on LG television panels is as follows.

On a note! On different models of LG TVs, the process of searching for digital TV channels looks similar, the only difference may be in the names of the sections in the menu.

Sony Bravia

The search for digital television is carried out in a similar way on television receivers from other manufacturers. However there are some differences in the access path to the beginning of the process for Sony Bravia TVs. So, automatic configuration will be carried out as follows:

• press on the remote control “Home” or “Menu”;
• click “Options”, and then click “Auto-tune digital channels”;
• choose digital, analog or both;
• click “Ether”;
• to start the search, click “Start”;

• save changes when the process is complete.

In a similar way, but with some differences in the names of the sections in the TV menu, automatic and manual setup of digital television via an antenna is performed on devices from Samsung, Philips, Toshiba and other brands.

According to statements by the Government of the Russian Federation, by the end of 2018, analogue television broadcasting will be stopped at the state level, so today digital television is broadcast almost everywhere. Unlike analogue, it provides a bright and detailed picture, good sound and a larger number of channels, some of which are transmitted in HD resolution. The easiest way to set up such television on your television panel is to buy and correctly install an over-the-air antenna, and then perform an automatic or manual channel search.

If the TV receiver is an old model, you will need to additionally purchase an external digital receiver. And if problems arise in the reception of digital TV channels, the cause must be sought first of all in the reception device - the antenna or television cable. Other problems happen much less frequently.

Digital television has become commonplace very quickly and has settled for a long time thanks to improved transmission quality and accessibility for a wide range of users. This direction in television is notable for its rapid development, and today there are more than enough specialists who are ready to help deal with connecting and setting up the service.

However, setting up digital television channels on a TV is a very simple procedure for the average user, so you can handle it on your own. To do this, you don’t even have to delve deeply into what digital television is in general. You need to know which channels on your TV are available in your area and whether the receiver is actually connected (that is, whether the TV is within the broadcast area).

The need to set up TV channels usually arises during the initial connection, when updating the device software, during which all user settings are lost, and if digital channels are lost for some other reason (the settings can be lost accidentally, for example, when children play with the remote control) . However, why this happens is not important, unless the firmware has crashed.

First, you need to consider the general algorithm of actions, that is, step-by-step steps, when setting up previously available channels on your digital television on Philips, LG, Samsung TVs and other leading models. It should also be taken into account that the sequence of actions and names of buttons and sections in each model can and will be different. However, it’s still not that difficult to figure out if you take your time and read what’s written on the screen and don’t click where you shouldn’t.

Standard algorithm of actions:

Take the remote control, press the “Menu” button, then select the “Options” - “Auto Configuration” section. A window will appear on the screen with a list of signal sources (antenna or cable). Select the cable and click “Start”;

As a result, a window with a list of possible signal sources should open on the screen of the television device, in which look for the “Digital” item and then click “Start”;

At the last stage, you should go to the “Search Mode” section. Find the “Full” category in it and manually fill in the fields with the following information:

Modulation – 256 QAM;

Frequency – 314 MHz;

Transmission speed – 6875 kS/s.

Some TV models, including LV, Philips, support network search, therefore, for these you do not need to manually enter any parameters.

Steps for LG TVs

Each individual TV model has its own factory firmware and individual functionality. However, in a situation where digital television channels have disappeared, all televisions have some similarities. Speaking of setting up TV channels on an LG TV, you need to press “Menu” on the remote control, select “Options”, click on the desired parameters for changes. In particular, by clicking on the “Country” section, you should select Finland or Germany.

After these steps, you need to go to the “Settings” item and then “Auto search”, indicating the cable connection as described above. As a result, a window will appear in which you should configure the values ​​according to the available instructions. If everything is done correctly, all radio stations and channels will appear again.

It should also be noted that the user can significantly simplify his task by using the automatic updating of TV channels, which is available on LG models. As a result, the previous list will be reset, and the channels will be tuned in a new sequence.

To use automatic setup, you need to go to the digital cable settings tab and click on automatic update.

If you have Philips or Samsung

If there is a channel failure on a Philips TV, you will also need a remote control, as, indeed, for any other model, not just Philips:

Through the “Menu” item, enter the “Configurations” section;

Click on the “Installation” section;

After the secondary menu appears on the screen, you need to click on channel settings;

After which another secondary menu will pop up, where you need to select “Automatic settings”;

If all transitions are completed sequentially and correctly, a message will appear warning that the channels will now be updated;

Click "Start".

The program sets up TV on Philips devices independently; after completion, you don’t need to do anything additional, you can use the TV as before.
