Probably, every person has faced the failure of one or another technique, and recently the situation when digital television does not work is relevant. A person turns on the TV to watch a long-awaited sequel to a series or favorite show, but gets only a blank screen. And digital television does not work every time for some reason that no one understands. Either this is not broadcasting, or the signal does not pass, or prevention is on separate channels. Digital TV does not work even if the antenna or even the TV itself breaks down, or maybe the cable goes somewhere. There are a lot of reasons why there is no TV broadcasting. This article will help you figure it out with some.
Main reasons
If digital TV does not work due to the lack of a signal, it will be immediately clear, because not a single channel will respond. So something is wrong with the antenna. Prevention cannot take place simultaneously on all channels, most often onone or, in extreme cases, 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 thing that can be checked, everyone knows, even people far from technology. You need to 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 cause of the breakdown of the TV, there is no point in independent actions. Only a service center or a private master who knows how to repair TVs will help.
Many-many if
Cable TV users have the opportunity to immediately contact the company that provides broadcast services as soon as they detect the absence of sound and picture. There are usually masters there, they will always help in all cases. If there is no cable TV, then first you need to get to know the neighbors and ask if everything is in order.
If digital television has not stopped working for them, then all problems must be sought from a specific user. If a regular indoor antenna is used, problems usually occur frequently, so many people now purchase special amplifiers, then there is no answer why digital television does not work. Antenna amplifier is a very effective help and is not difficult to obtain - it is not too expensive and is sold everywhere, in every hardware store.
Common problems
Satellite TV antennas are very powerful, but even they sometimes refuse to transmit a signal, and a frustrated user spends a lot of time with his phone in his hands, asking the broadcaster why digital TV is not working today. This problem is considered to be common. The satellite is moving, namely, the antenna was tuned to it, and it was from it that it caught the signal.
He is, but not available. The problem is solved quite simply, but not every user will be able to reconfigure the antenna to another satellite on their own, so it’s better to contact specialists right away. In addition, it is not a fact that this satellite has shifted. The position of the antenna may also change due to the wind or from the fall of an object on it, for example, a tree branch.
On the benefits and harms of curiosity
There are many reasons, and even more solutions for users, unless, of course, they can correctly determine the reason why digital television does not work well. If the cause is not clear or the user made a mistake in the diagnosis, problems and additional ones may appear with independent actions. Therefore, it is better to resort all the same to the help of real professionals. They will determine why 20 digital TV channels are not working, or, for example, only ten out of twenty are working.
A user who is not too well versed in modern technology is unlikely to be able to do this. But there are (and in a fairly large number) people who are inquisitive, and this is their choice: to establish a supplysignal or break something else. On your own, you can only eliminate some minor flaws, and those that are in plain sight, for example, place the cable correctly to the socket or select the amplifier for the antenna in the store. The rest must be left to specialists.
Far and close
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 with high quality, and many more questions regarding broadcasting and reception. But very often there are situations when it is difficult to solve such problems in a metropolis. It is impossible even to list all the cases in which the master will not 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 on the Internet about signal problems. City dwellers generally have much less problems with calling technical support, but how much more difficult it is to solve such issues far from civilization! In the outback, time does not flow so quickly, modern technologies come there very late or never come at all. Therefore, digital TV lovers need to find out what options exist for them today.
Three options
Firstly, this is cable television, when the signal will be distributed directly through the television cable, and it is connected to a separate TV set. This is a very high quality transmission, butit is not available in every outback, mainly in cities. And the subscription fee is quite high.
Secondly, this is satellite television, when the signal comes from near-Earth orbit and is received by an individual antenna ("dish"). This can be done everywhere, 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 question is still raised by the user: why did digital television stop working?
Thirdly, this is terrestrial television, when the signal is distributed by ground relay stations, and it is received by an individual antenna. There are few costs here, but the signal level is much lower, the reception quality 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's mood will deteriorate from time to time due to the fact that terrestrial digital television does not work.
Of course, now everywhere, everyone and always helps out the Internet, where you can always watch whatever you want. However, this article is not about these cases.
Theory
All these methods are good enough. But it is necessary, when choosing one of them, to present at least in general terms how they differ. For example, just terrestrial television and digital are completely different. The latter lies in the fact that digital coding is used to transmit the image and sound - both the audio signal and the video signal. And digital channels are used for transmission. Such encoding ensures minimal losses during 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. The boundary state and interference are absent here. The only exception is that there is poor communication quality. Then the TV seems to slow down, turn off and turn on again. And this can only be fixed in one way - you need a different antenna or the existing one needs to be raised higher and deployed towards the TV tower.
It should also be noted that many users do not know that digital television is always a limitation in the number of 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 good viewing, you need to purchase, first of all, a television antenna, a TV set or a Set Top Box with support for signal compression standards and a tuner (you need to find out which one is not outdated at the moment). Many of the most modern TVs do not need a set-top box, they only need an antenna. But not everyone has these, 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 chosen to use terrestrial digital television. You can use the most commonan antenna that catches well two or three channels in a fairly good quality, a couple more - in a bad one, but even those in very good weather. This antenna needs an attachment. For example, DVB-T2. Any can be, they are technically almost identical. Most often, set-top boxes have two outputs - SCART or "tulip" and an HDMI output, as well as a USB connector to view the contents of electronic media. The boxes for all consoles are different, but they seem to be made 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 the "tulip" (usually sold in one set with the set-top box) must be connected directly to the TV.
Here you need to know that the RCA connectors for stereo sound and video signal - this is the same "tulip". Yellow is for video, white is for left stereo or mono, and red is for right stereo. If the kinescope of the TV is obsolete, it is the "tulip" that will help out. If the TV is plasma or LCD, 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 console is not too difficult. Even if you just do everything by default, the quality is quitewill satisfy even connoisseurs. The main thing here is to set up the channels themselves. The menu has a channel search. You can also select auto search. In a few minutes everything will be ready. For almost any locality, this will be enough.
From electronic media
As already mentioned, a digital set-top box is needed in order to play back recorded on a flash drive. To do this, you need to insert a USB device into the set-top box, go to the menu, select "USB" "Multimedia" accordingly, then select the desired format - video, pictures or music. The contents of the flash drive will open on the screen. Now you need to select the desired folder and open the file. Everything is even easier than doing it with a laptop or computer. However, many people still cannot deal with these operations on their own. Especially the elderly, who do not keep up with the rapid movement of technological progress, need help. Young people do it best. And even small children are much more adaptable.
But that's not all. A user who has such a set-top box for an antenna for digital television should know that it is possible to perform the reverse operation as well. For example, burn your favorite program directly from the TV to a USB flash drive. And the steps for this purpose are just as simple. It is enough to press the "Rec" button on the control panel of the set-top box, and the recording will obediently go to the USB device. In a word, digital television today, even for a remote locality, is not a myth andnot a dream, but a very feasible thing. And if it is digital terrestrial, then a resident of the outback or temporarily settled in a dacha, in a village, does not have to spend about ten thousand rubles on installing satellite television, and then pay a considerable monthly fee. It is possible today to achieve comfort with small means.
Trust the provider
Practically everyone enters into an agreement with a provider in order to receive a digital television service. For long-established and sufficiently powerful firms, a set of equipment is supplied to the user, as, for example, by Rostelecom. However, almost all providers do not satisfy the client on the day of the request. You need to wait a day or two, and if it is a remote place, then a week, not even one. In order not to lose time, and digital television started working right away, you can make the initial setup yourself. Literally everyone can need this knowledge and skill, 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 configuration 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. So it's better to choose2.0, and if there is no other provider nearby, 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 technicians. Settings with someone else's equipment at Rostelecom do not match. The user is lucky if another provider is nearby and can connect him to their network.
Situations
1. Departure of the set-top box from the regular mode. This can happen if it is turned off for a long time. You just need to plug it into the network and not be afraid of the inscription, which indicates that the DRE channel is encoded. If you wait a couple of hours, the receiver will fully restore and all encrypted channels will open.
2. It may happen that the set-top box (receiver) is not registered. To exclude 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 get lost. Such cases are described above. Here you will need the help of a specialist who will reactivate them.
4. If the sign of a paid channel suddenly appears on the screen, 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 software compatibility. Some dexterity is required here. If the receiver is GS-HD, you need to restore the list of channels in the menu (there is such a key there). And if it doesn’t work, on the remote control and on the receiver panelat the same time (this is the most important) you need to press two buttons - CHANNEL and TV / RADIO. Precisely at the same time - four fingers. Then press STANDBY on the remote. And everything has to fit together in the software.
6. When the message "No signal" appears on the screen, it is worth looking for a solution to the problem with the antenna. This has been discussed a lot above.
7. Check cable. If it does not help, call a specialist.
