There are many problems that cause channels to stop showing on the TV screen. But, fortunately, along with these malfunctions, there are appropriate methods for eliminating one or another malfunction in the device. Experts divide them into 2 parts: 1) channels on satellite television do not work, 2) channels on digital television do not work.
Lack of channels on the satellite
This type of TV broadcasting is widespread mainly in the CIS countries. By itself, satellite television is a rather fragile product, which, with the most elementary "additional" actions, will ruin the entire setup of the receiver.
If there are no channels, then check the status of the following indicators:
- the indicator light on the receiver should be on. If it burns periodically or is completely turned off, then most likely the problem is in the breakdown of the receiver or there are some voltage problems, for example, there is no current in the extension cord or the cord is damaged;
- the card included in the kit must be inserted into the hole specially designated for it. For a number of reasons, this card can accidentally pop out, so in case of problems it is recommended to check its position. If there are any doubts about this, then you should take the instructions and see how to correctly place the card;
- connection of wires. See if there is contact between the receiver, the satellite dish and directly with the TV. These wires must be in good condition and connected securely;
- serviceability of the plate. Due to the influence of aggressive weather conditions, problems arise in the work satellite dish, and sometimes they become fatal altogether. Among them, mechanical damage often occurs due to hail or lightning, as well as due to icing.
No channels on digital TV
Exists the following problems, due to which digital television stopped showing channels:
- incorrectly set mode. If the TV is not in the mode in which the wires of the TV receiver were connected to the jack, then the TV will not work in this case. It is necessary to set the appropriate mode;
- using the wrong remote. It should be remembered that in the case of using both satellite and digital television... The remote control from the TV itself is only needed to turn on or off the device. The subsequent switching of channels or their setting is carried out by the remote control for the receiver;
- non-payment of TV channels. If a package of channels is suddenly blocked, then this may indicate that you have not paid your provider for their use for a long time;
- position of the wires. It is necessary to carefully check the correctness and reliability of the connection of the cords to the corresponding slots, as well as the condition of the card, which must also be inserted into the correct slot.
If you are using a regular old antenna and the TV channels suddenly disappeared, then you will need to do independent search signal on the TV itself using special function, which is present in the Menu.
Sometimes the reason for the lack of channels is not so easy to identify, since the incorrect operation of the device may consist not only in software, but also in physical nuances. If you have any difficulties and are not sure about own forces, then we advise you to contact the specialists of the VseRemont24 service center. Our guys will be able to advise you on any issue of interest, diagnose the device for faults and do all the necessary repair manipulations that will help you restore the operation of your equipment as quickly and easily as possible.
Probably, every person was faced with the refusal of one or another technique, and in Lately the actual situation is when digital television does not work. A person turns on the TV to watch a long-awaited sequel to a series or a favorite show, but receives only a blank screen. And digital television does not work every time for some reason, no one understands. Either there is no broadcast, or the signal does not pass, or prevention is on separate channels. Digital television does not work even if the antenna or even the TV itself breaks down, or maybe the cable goes off somewhere. There are many reasons why there is no television broadcasting. This article will help you figure it out with some.
Main reasons
If digital television does not work due to the lack of a signal, it will be immediately clear, because no channel will respond. So something has happened to the antenna. Prophylaxis cannot take place on all channels at once, most often on one or, in extreme cases, on several. The rest will work, and why digital television does not work is not a question for such a situation. If the cable has gone somewhere, then the question is legitimate, because silence and a dark screen will be everywhere.
The first way to check this is known to everyone, even people far from technology. Disconnect and reconnect the cable. If it does not help, then contact the specialists and ask them why digital television does not work today. If the user suspects the reason for the breakdown of the TV, it makes sense to independent action no. Will only help service center or a private technician who knows exactly how to repair TVs.
Many, many if
Cable TV users have the option to immediately contact the broadcasting company as soon as they find that there is no sound or picture. There are usually masters there, they will always help and in all cases. If there is no cable TV, then first you need to get to know your neighbors and ask if they are all right.
If their digital television has not stopped working, then all problems should be sought from specific user... If a conventional indoor antenna is used, problems usually arise often, so many now purchase special amplifiers, then one answer disappears, why digital television does not work. Antenna amplifier - very effective help, and it is not difficult to get it - it is not too expensive and is sold everywhere, in every home appliance store.
Common problems
Satellite TV antennas are very powerful, but even they sometimes refuse to transmit the signal, and the frustrated user spends a lot of time with the phone in hand, asking the broadcasting company why digital TV is not working today. This problem is considered common. The satellite is shifting, namely, the antenna was tuned to it, and it was from it that it was catching the signal.
It is there, but not available. The problem is solved quite simply, but not every user will be able to independently reconfigure the antenna to another satellite, therefore it is better to immediately contact the specialists. In addition, it is not a fact that this satellite has shifted. Maybe the antenna position can be changed due to the wind or from a fall on it of any object, a tree branch, for example.
The benefits and harms of curiosity
There are many reasons, and users have even more solutions, if, of course, they cannot correctly determine the reason why digital television does not work well. If the reason is unclear or the user made a mistake in the diagnosis, problems and additional ones may appear with independent actions. Therefore, it is better to resort to the help of real professionals. They will determine why 20 digital television channels do not work, or, for example, out of twenty, only ten work.
Not too well versed in modern technology the user is unlikely to be able to do this. But there are (and in quite a large number) people who are curious, and this is their choice: to set up a signal or break something else. You can only eliminate some minor flaws, moreover, being in sight, for example, the cable should be correctly placed to the socket or the amplifier for the antenna should be chosen in the store. The rest must be left to specialists.
Far and near
In the city, it is much easier to get answers to the following questions: why digital television channels do not work, why sound and image reception is poor, why not all channels work efficiently, and many more questions regarding broadcast and reception. But very often there are situations when it is difficult to solve such problems even in a megalopolis. It is impossible even to list all the cases in which the master cannot immediately cope if digital television does not work.
Kaluga, for example, is a very modern city, but for some reason there are a lot of reviews from there on the Internet about problems with the signal. Urban residents actually have much less problems with calling technical support, but how much more difficult it is to resolve issues of this kind far from civilization! In the outback, time does not flow so quickly, modern technologies arrive there with a great delay or never arrive at all. Therefore, fans of digital television need to find out what options exist for them today.
Three options
Firstly, this is cable television, when the signal will propagate directly through tv cable, and it connects to a separate TV. This is a very high-quality broadcast, but it is not available in every remote area, mainly in cities. And the subscription fee is quite high.
Secondly, it is satellite television when signal goes from near-earth orbit and is received by an individual antenna ("dish"). This can be done anywhere, and the sound and picture will be of high quality. The subscription fee is quite high, the equipment is also expensive. And from time to time, the user still poses a question: why did digital television stop working?
Thirdly, over-the-air, when the signal is propagated by ground-based repeater stations, and it is received by an individual antenna. There are few costs here, but the signal level is much lower, the quality of reception depends on everything in the world - here is the weather, and the distance from the relay tower, and the height of the antenna mast, and much, much more. And every user from time to time will get spoiled by the fact that digital terrestrial television does not work.
Of course, nowadays everywhere, everyone and always helps the Internet, where you can always see whatever you want. However, this article is not about these cases.
Theory
All of these methods are good enough. But when choosing one of them, it is necessary to present at least in general outline, What is the difference. For example, just terrestrial television and digital are completely different. The latter lies in the fact that for the transmission of image and sound is used digital coding- both audio signal and video signal. And for transmission are used digital channels... Such coding ensures minimal losses in signal delivery, since no interference of the encoded information is terrible. And if digital television channels do not work, then they do not work completely, at all. And if they work, then only in excellent quality. There is no borderline state or hindrances here. The only exception is what happens poor quality communication. Then the TV kind of slows down, turns off and turns on again. And this can be corrected in only one way - you need another antenna or the existing one needs to be raised higher and turned towards the TV tower.
It should also be noted that many users do not know that digital television is always a limitation in quantity. available channels... Depending on the region, there may be ten, twenty, the number varies. The principle does not work here: I raised the antenna higher and caught absolutely everything. No, only what is available is configured. For have a nice watching you need to acquire, first of all, tv antenna, TV or television with support for signal compression standards and a tuner (you need to find out which one on this moment not deprecated yet). To many of the most modern TVs no prefix is needed, the antenna is enough for them. But not everyone has such, and therefore often users are looking for the reason why the set-top box for digital television does not work, although the problem may be in the TV itself.
Practice
Let's say you have selected terrestrial digital television for use. You can use the most conventional antenna, which catches two or three channels well in a fairly good quality, a couple more - in poor quality, but even those in very good weather. Such an antenna needs a prefix. For example, DVB-T2. Anything is possible, they are technically almost identical. Most often, set-top boxes have two outputs - SCART or "tulip" and HDMI out as well as a USB connector to view content electronic media... The boxes are different for all consoles, but they are made as if at the same factory in China. Therefore, when buying, you need to carefully examine the control panel as the most frequently used item, whether everything is in order with it. Otherwise, there will be problems in switching channels, adjusting the volume and the like. If all is well, you can connect the antenna to the set-top box, and the set-top box using a "tulip" (usually sold in one set with the set-top box) must be connected directly to the TV.
Here you need to know that RCA connectors for stereo sound and video signal are the very "tulip". Yellow is for video, white is for left stereo or mono, and red is for right stereo. If the TV picture tube is morally outdated, it is the "tulip" that will help out. If the TV is plasma or liquid crystal, there is an HDMI output, and you need an appropriate cable, another will not work. You need to purchase it separately. Otherwise, the user will not like the image too much. The TV needs to be switched to AV mode, then the set-top box interface will appear. Setting up the set-top box is not too complicated. Even if you just do everything by default, the quality will satisfy even connoisseurs. The main thing here is to configure the channels themselves. There is a channel search in the menu. You can also choose autosearch. In a few minutes everything will be ready. For almost anyone settlement this will be enough.
From electronic media
As already mentioned, it is needed in order to reproduce what was recorded on a USB flash drive. To do this, you need to insert USB device into the console, go to the menu, select "USB", "Multimedia", then select desired format- video, pictures or music. The contents of the flash drive will open on the screen. Now you need to choose desired folder and open the file. Everything is even easier than doing it with a laptop or computer. However, all the same, many people cannot figure out these operations on their own. Especially the elderly, who cannot keep up with the rapid movement of technological progress, need help. Young people do it best. And even small children adapt much more easily.
But that's not all. A user who has such an antenna attachment for digital television should know that it is possible and reverse operation produce. For example, record your favorite program on a USB flash drive directly from the TV. And the steps for this purpose are just as simple. It is enough to press the "Rec" button on the set-top box control panel, and the recording obediently goes to the USB device. In a word, digital television today, even for a remote settlement, is not a myth or a dream, but a completely feasible thing. And if it is digital terrestrial, then a resident of a remote place or temporarily settling in a dacha, in a village, does not have to spend about ten thousand rubles on installation satellite TV, and then make a considerable subscription fee... You can still achieve comfort today with little money.
Trust the provider
Almost everyone enters into an agreement with a provider in order to receive digital television service. Have been working for a long time and have enough powerful firms and a set of equipment is supplied to the user, as, for example, from Rostelecom. However, almost all providers do not satisfy the customer on the same day. You have to wait a day or two, and if it's a hinterland, then a week, not even one. In order not to waste time, and digital television will start working right away, you can make initial setup on one's own. This knowledge and skill can be needed by literally everyone, even if you have to move the TV to another room or change it to a new one you just bought. Therefore, everyone should understand the connection diagrams and adjustment technologies.
The same Rostelecom offers this service in two versions - together with the Internet (Interactive 2.0) and a separate digital television (Interactive TV). The latter can only work on a router that belongs to the company, others will not work. And the routers at Rostelecom are disgusting, in all the reviews this is exactly what is written. Therefore, it is better to choose 2.0, and if there is no other provider nearby, then you will have to call technical support almost daily with the question: why does digital television not work during the day? You won't be able to connect version 2.0 on your own, you still have to wait for the technicians. Rostelecom's settings do not match with someone else's equipment. The user is lucky if another provider is nearby and can connect it to their network.
Situations
1. Leaving the set-top box from normal operation... This can happen in the event of a long shutdown. You just need to plug it into the network and not be intimidated by the inscription, which says that the DRE channel is encrypted. If you wait a couple of hours, the operation of the receiver will be fully restored and all encrypted channels will open.
2. It may happen that the set-top box (receiver) is not registered. To eliminate this situation, you need to look at the identification number on the back panel and enter it on the provider's website.
3. Sometimes the antenna settings are lost. Such cases are described above. Here you will need the help of a specialist who will reactivate them.
4. If a sign suddenly appears on the screen pay channel, you just need to pay for a subscription to the provider's services, apparently, the user forgot to do it on time.
5. Sometimes there are difficulties with compatibility software... It will take some dexterity here. If the receiver is GS-HD, you need to restore the channel list in the menu (there is such a key there). And if it doesn't work out, on the remote control and on the receiver panel simultaneously (this is the most important) you need to press two buttons - CHANNEL and TV / RADIO. Exactly at the same time - with four fingers. And then press STANDBY on the remote control. And everything should fit together in software.
6. When the screen says "No signal", it is worth looking for a solution to the problem with the antenna. Much has been said about this above.
7. Check the cable. If it does not help, call a specialist.
Recently, Rostelecom began to provide all its clients with new service with the name "Interactive T. This service provides access to a large number different thematic channels and "Video rental" options. The main hardware for such a TV is a special set-top box, which is connected to the TV via the HDMI port.
Problem situations, due to which the TV starts to work incorrectly, can arise due to several factors. The most frequent causes of system failures are considered to be emergency breakdowns on the provider's line, a failure in the equipment itself or its erroneous setting, mechanical damage to the apartment cable.
Today's article will acquaint users with the main problems due to which television from the Rostelecom provider does not work properly, and will teach you how to fix them on your own, without calling the company's masters.

The TV is not receiving a signal
In the case when after connecting the set-top box to the TV the image does not appear on the screen, the user needs to correctly set up his own TV. Majority modern devices equipped with a variety of interfaces for connecting with additional devices. If the set-top box was connected to the TV via HDMI port, then the same type must be set in the settings, because many TVs do not support automatic search new devices.The TV remote control has a button named "Source", which is responsible for the signal source. Clicking on it opens special menu, where you need to select the port to which the set-top box from Rostelecom is connected. After selecting the required parameter, an image should appear on the screen immediately. If this does not happen, then try to disconnect the set-top box cable and reconnect it - it is possible that the contacts are simply not tightly attached to each other and do not pass the signal.
If the problem is still not resolved, the user needs to call a specialist who will diagnose the ports of the provider's set-top box and TV.
Breakdowns on the provider's line
When, after the correct connection of all equipment, a notification "No IP address" appears on the subscriber's screen, this means that there is a problem somewhere in the network.The reason for this may be a malfunction in the patchcord, a failure in the router itself, or a breakdown on the provider's line. If during the day the television worked and all the router settings were not changed by the subscriber, but the television disappeared, this indicates an accident on the provider line.
In such cases, you need to call the service technical support Rostelecom call 8 800 70 71 811 and notify about any problems that have arisen. You can search required numbers on the bottom panel set-top box... If on this period the line is being serviced, the operator on duty will notify the subscriber about this and will tell the approximate time of their end.
Try to connect the set-top box to the Rostelecom cable directly, bypassing the apartment router. If the television has not appeared, then the subscriber's router and its wiring are not the causes of the malfunction.
TV box malfunction
Absence television signal may be due to various glitches in the set-top box itself. If there is a malfunction in its firmware, it is very difficult to deal with it with your own hands, it is better to call a company specialist.In the situation when, after turning on the TV, it continuously displays one screen saver or even dark screen- it is required to turn it off and take it to the nearest Rostelecom center for replacement or repair.
You can get information on the location of the nearest customer service centers on the Rostelecom website. To do this, you need to use the search service. Go to the site from any browser and simply enter your region of residence and city in the search bar. After these actions, all the addresses of the provider's representative offices in the subscriber's city will be shown on the map that appears.
Mechanical damage to the cable
After an unexpected absence of a television signal, when a notification in the form of "No IP address" is shown on the screen, the consumer must first of all carefully examine all apartment wiring for mechanical damage... If the patch cord is bent somewhere or breaks in several places, then it may stop receiving the incoming signal, which will cause the television to stop working.It is also worth checking if the cable is pinched by the leg of the sofa or table, if it is crushed by the interior door, and also if it is damaged by pets. Another reason could be oxidation of the contacts on the cable connector. In any of all these cases, you just need to replace the patch cord between the router and the set-top box.
Router problems
In the case when the television is connected through a router, and not directly, then it can also serve as a source of problems. When you first connect the TV to the router, you must enter special settings- enable IGMP reception, allocate a separate port for the set-top box, etc. All such settings, for each model of the set-top box, can be found on the official website of the provider Rostelecom, in the column “ Technical assistance". Also on our site we have already considered the issue of setting and viewing IPTV... And it is also necessary to clarify whether the subscriber's equipment supports the transmission of multi-traffic.If the television worked today, and the problems started recently, restart the router by turning it off for a minute and turning it back on. It is acceptable that there were interruptions in the power line, which led to the device freezing. If the problem persists, check all user equipment configurations. Their failure could happen due to power surges or as a result of inexperienced actions of other users. You also need to check if LAN port, which is specified in the settings, the TV is connected.
Where to call to solve the problem
Rostelecom has many technical support departments for its customers. If any problem arises, the subscriber can make a call to the number Unified Service support 8 800 100 08 00 or 8 800 18 11 830 and get advice.Planned analog shutdown television broadcasting in favor of "numbers" is in full swing. Digital TV is not only high quality the transmitted image and sound, but also stable broadcasting. However, sometimes problems with television do arise. As a result, the device does not catch digital channels.
The first time the receiver is started, the user tunes in the TV channels. Mostly this process is carried out automatically. However, what to do if due to bad signal Can't tune in the channels included in the two free multiplexes on the TV?
In fact, there may be several reasons. It is about them now and there will be a speech... Let's take a close look at the main difficulties faced by users in order to answer the question of why digital television is not shown today. Let's give real arguments and effective ways solutions to emerging problems.
Reasons for not showing digital channels
All reasons can be conventionally divided into 4 categories:
- hardware or software glitch in the operation of equipment;
- holding renovation works;
- natural factor;
- termination of the broadcast.
Of course, you first need to determine why digital television is not working. Diagnostics boils down to the study of symptoms, for example, if the image has become square or the sound is delayed, then this may be due to bad weather or a thunderstorm.
It is almost impossible to avoid the listed problems, since for the most part they are of a force majeure nature. The only exception is hardware failure. Preventing software crashes is easy enough - keep up to date operating system prefixes. Hardware damage is even easier - follow the rules for using the equipment.
Now we will consider in detail what determines the quality of broadcasting, and also determine why there is no signal on digital television. Let's focus on the most common reasons that have already been voiced earlier.
The equipment is out of order
If it doesn't work cable TV, then first you need to figure out what exactly caused the failure:
- receiver breakdown;
- damage to the antenna;
- cable malfunction.
Let's deal with incorrect work digital set-top box... It makes no sense to focus too much on this point, since the symptoms of a receiver breakdown are obvious. When the receiver is turned on, no indicators will light up, indicating that the equipment is starting up. Sometimes the LED is on, but extremely dim.
Many tuners are equipped with an independent 5 volt power supply. Mostly the set-top boxes are equipped with a standard adapter, so it is extremely easy to check its performance, you can connect a similar component from the router.
In some situations, testing the voltage level with a multimeter does not give results, since in the absence of loads, the measurement will show the 5 Volts set by the regulations.
Poor sound from DVB-T2 tuner is another symptom. Sometimes the device simply reboots or shuts down randomly, does not respond to commands with remote control management.
Another common type of hardware problem is cable and connection faults. As a result, absolutely all channels are not shown as the signal is lost. Carefully check absolutely all connections and cable integrity.
Particular attention should be paid to the white wire (RG-6), which is intended for indoor installation. The service life of this cable is extremely short, especially if you used it in the external installation process. Water enters it, thereby destroying the braid.
The third reason for equipment problems is antenna malfunction. Indoor antennas fail extremely rarely, in contrast to external ones. Mostly precipitation or thunderstorms become a catalyst for malfunction. You can try to reconfigure the receiver several times, but the channels will not be found. In this case, follow the proven algorithm of actions:
- Check cable and plugs.
- Evaluate the voltage supply from the set-top box or power adapter.
- Connect a new antenna.
Remember, if the antenna for some reason does not pick up channels, check if it is really pointed at the signal transmitter.
All of the factors listed above fully explain why the TV does not pick up channels. Modern models TVs are equipped with built-in T2 set-top boxes, which also sometimes fail.
Bad weather
If you have had to deal with satellite TV, then you probably know that during rain or heavy snow, the picture literally crumbles into squares or disappears altogether. With digital DVB television there are similar problems with excessive rainfall.
From the antenna to the receiver comes weak signal, because of this, the TV does not show well in bad weather. It is extremely easy to identify this problem; you just need to test the signal strength. If there is no digital TV signal or it is very weak, it is necessary to increase it, mainly for this they are used additional devices- amplifiers.
Stop broadcasting
If digital TV channels do not work due to preventive maintenance, then go to the website rtrs.ru, information about the time and duration of such events is displayed here. In addition, a sign with a corresponding notification will appear on the TV screen.
Sometimes the receiver catches only 10 channels of the first multiplex, but at the same time the second packet was broadcast just yesterday. In this case, check its signal strength. If he is zero, it is more likely that the second multiplex is simply disabled. This is mainly due to broadcasting in test mode. After the equipment collected information, the TV channels disappeared.
As mentioned earlier, the first multiplex is mandatory, so it works correctly almost throughout the entire territory of Russia. There are certain difficulties with the second multiplex. They are largely due to a lack of funding. In addition, analog TV is still active in some regions, therefore free frequencies corny not enough.
A complete rejection of analog TV broadcasting will contribute to the early appearance of the second multiplex in all regions of Russia.
Renovation work
We have already established what causes the digital television signal to disappear, the reasons can be really different. For example, sometimes TV does not work during the day due to regular or force majeure repairs. You can also find out about this by visiting the website rtrs.ru. Often they are held after severe bad weather, which causes damage to the equipment placed on the tower.
