Does the TV turn off? The reasons may vary. Why channels disappeared on a digital set-top box

All who live in the century high tech are confident that these technologies are designed to make life easier. This is true, although situations do occur that can contribute to nervous overstrain rather than relaxation. For example, when some of your favorite TV channels disappear. Naturally, this is far from the most best experience, especially when you want to watch TV, and he throws up similar, not too pleasant surprises.

If you also faced such a nuisance, then there is no need to rush to the TV master, especially since it may take some time. If you want, you can try to restore digital channels on the TV on your own. Of course, a 100% return of their broadcast cannot be guaranteed, but, as a rule, self-manipulation helps.

Reasons for missing channels

As a rule, the TV shows two dozen standard digital channels... But sometimes even they disappear, if not completely, then partially. Considering that they are free, problems with broadcasting can be associated with many reasons, but the main ones can still be distinguished:

    Problems with the program;

    There is a problem with the signal receiving equipment.

Both the first and second situations can be solved, but they require completely different manipulations. If it's the hardware, then try regular user they do not always help, and can even harm. If the trouble is with the TV channel itself, then this happens with one, maximum, two programs, but not with half of the broadcast channels at once.

Let's figure out what the figure is before doing any manipulations related to the recovery processes. So, the advantages of digital television channels are improved signal reception, cooler sound, picture and other characteristics, compared to the rest. free systems... But only 20 channels are free, which are periodically disconnected and changed, therefore in a situation when some TV channels disappeared, there is nothing surprising.

    The symbol appears on the screen pay channel... This is a sign that the service subscription is about to end. If you did not pay for the figure on time, the answer to the question why the channels on digital set-top box, is obvious. You need to replenish your account and then they will start working again, of course, if this message does not pop up on. In this case, it is better to contact the provider for clarification;

    There may also be difficulties with the software, more precisely, its compatibility. If this is a GS-HD receiver, then you need to go to the menu and press the "Restore channel list" button. If new does not fit software, then on the same receiver you need to: find the TV / RADIO and CHANNEL buttons on the remote control, in addition, in parallel on the receiver panel, press the same buttons. But it is very important to do it at the same time. Then press the STANDBY button on the remote control;

    The inscription "No signal". It is already a common sign of antenna problems. If the antenna does not work as it should, it is not surprising that dozens of channels began to disappear. If the device is new, then it may not have customized programs, therefore this fact should be clarified. But if the programs used to work, but disappeared in an instant, you should still go outside and see if the antenna has moved due to strong winds or something like that;

    Sometimes the connection between the antenna and the cable, or the cable and the set-top box, is broken. If such suspicions arise, you need to make sure that the cable is connected to the LNB IN jack.

When none of the above list helped, there is only one way out - to call for help. The master will definitely figure out what's the matter and return your favorite programs.

Why are only 10 out of 20 digital channels shown?

Over the past two or three years, digital TV users have often complained that after updating their channels, half of the programs that were shown before disappear. Since then, people have a natural question - why did 10 channels disappear, if they used to work and were free?

Many forums are trying to find out the answer to this question, therefore different versions are being put forward. For some, the channels of the first multiplex do not work, for others, the second. This suggests that the reasons for these troubles lie in various difficulties in signal reception associated with technical works or the peculiarities of the functioning of digital television.

Perhaps, after a while, the channels will restore their broadcasting, so you should not worry in advance where ten disappeared at once. popular channel... The RTRS clarifies that while the work is being carried out in test mode, for some regions such difficulties will become the norm. Sometimes re-search channels or flashing the set-top box helps, but if this is not your case, you can use analog or satellite TV where the signal works without such significant interruptions.

In this material, we will talk with you about the problems that lead to the fact that channels are not shown on the TV or the TV does not work.

Consider below ways to solve problems with TV, which were divided into 2 parts - when the TV does not work at all in the literal sense (it does not start, etc.) and when there are simply no channels, i.e. TV as a device works (gives life signals), but there are no channels.

TV does not turn on

If your TV does not start at all, then this may already indicate very serious problems with it, in which you often need to contact service center for the help of specialists, but we will not bury your TV ahead of time and we will make sure what is wrong with it.

1. Check that the power cord is plugged into the outlet and that there is electricity in the outlet.

(Children may play and accidentally pull out the cable).

2. If you try to turn on the TV using the path remote control, make sure that the batteries are not discharged, and that the signal receiving surface is not obstructed by anything and is straight line with a remote control.

Usually a small light is on on the TV, notifying that the TV is working properly, just turned off. If it is on, and the TV remote control does not turn on, then something is wrong with the remote control.

3. It may turn on, but a black screen appears on the TV. This suggests that you "clicked" something on the remote control the day before and turned on that mode or entered it into program interface where the screen is black. Try clicking on channels and trying something different.

4. Perhaps there was a thunderstorm a day earlier, which is very common reason in the refusal of both televisions and other household electrical appliances. If everything is true, then your TV will have to be transported by specialists.

No TV channels

Let's take a look at the situations where the TV actually turns on, but does not show the channels as such. If your TV is "live", but there are simply no channels, then you are in the material below.

Remember! If you have satellite or digital television, you must use the remote control of the receiver / receiver, not the TV, to select channels. And before that, the TV with its own remote control must be switched to AV mode or the one where your TV is connected.

There are quite a few materials on what and how to do when the channels do not work, so we made separate articles about this.

If you have an ordinary old antenna, then you need to search for channels on the TV using the corresponding function in the TV MENU.

If you still have any questions regarding the operation of the TV and the display of channels, ask them in the comments.

Instructions

Purchase an RF coaxial cable. Given that the TVs are likely to be in different rooms, a cable longer than 10 meters would be required. Also buy a splitter (splitter). It is a gold plated device that has one coaxial port on one end and two (or three) on the other.

Accept necessary measures precautions, as installing an antenna and laying cables in the house can be associated with health risks.

Choose a place to install the antenna and install it. The higher it is placed, the better the reception will be.

Connect antenna and splitter via RF coaxial cable. For the connection, use a single incoming port on one end of the splitter.

Connect TVs using the outgoing ports on the other (free) end of the splitter.

Secure the cables so as not to damage or step on them. Use electrical tape to secure the cables.

Turn on your TVs to test the connections on each one. If one of the TVs has bad reception make sure the cable is not damaged and is securely fastened.

Buy a second splitter if there are more TVs than the available ports on the first splitter. Connect the two taps together by attaching a cable to one of the ports on the first and only inbound port on the second. Splitters can reduce the strength of the transmitted signal. If you need to connect to one antenna, for example, four TV distribution amplifiers will be required to improve picture quality.

It so happens that there is a need for e in every room, so that everyone has the opportunity to watch their favorite show or movie. There is an easy way to solve the problem of connecting a second TV.

You will need

  • Second TV
  • TV cable
  • Antenna splitter
  • Antenna plug

You will not surprise anyone with the presence of several televisions in the house now - this has long been the norm. But when purchasing another TV, it will not be superfluous to think about how to connect it to an existing one. antenna.

Instructions

To carry out the installation of the connectors, you will need minimal skills in working with a television cable, the presence of side cutters and a painting knife. First you need to clean the cable from the top layer of insulation without damaging the shielded braid, then move the braid and clean the center conductor. After that, you can put on the connector and connect it to the splitter. It is important to avoid contact between the shielded braid and the center conductor. tv cable between themselves.

Useful advice

When installing the splitter, strictly follow the cable connection procedure indicated by the arrows.

In order to TV set began to receive channels, it is not enough just to bring it into the room and turn it on. An antenna must also be connected to it. The number of received channels and the quality of their reception depends on its correct choice.

Instructions

Remember the main rule: if antenna cable grounded (if the antenna is collective, this is always the case, and often it is also grounded for individual outdoor ones), you cannot touch the metal elements connected to the socket and the plug at the same time when they are not connected to each other! It is also forbidden to touch simultaneously the metal parts of two devices plugged into an outlet and not connected to each other (for example, TV set and the DVD player) and the cables connected to them, even if the antenna is not grounded. In addition, do not touch metal parts TV set and any video equipment, as well as an antenna cable and a telescopic antenna in the event that your body has acquired an electrostatic charge from the CRT screen TV set a (for example, when wiping it). Never install an outdoor one if you are not sure that you can provide reliable lightning protection. Solder any grounded antenna cables only with properly insulated soldering irons.

In order to TV set with a single-pin telescopic antenna built into it, insert the plug that emerges from the body of the device on the wire into its antenna socket. If there are two jacks that correspond to different ranges, replace the plug in the jack that matches the range in which this moment reception is underway.

If k TV set It also has a ring antenna, the built-in telescopic antenna should be connected to the jack corresponding to the meter wave range, and the ring antenna to the jack corresponding to the decimeter wave range. Some TV set The second antenna will stick directly to the socket, while others will have to attach it to the first.

If to TV set a two-pin telescopic antenna is attached, screw a special adapter-matching adapter to the clamps of the symmetrical ribbon cable coming out of it, if this has not been done before. Then connect the adapter to the antenna jack TV set a (for such devices, it is usually one).

If the room or outdoor antenna is all-wave, and y TV set and separate inputs for MV or UHF antennas, use a splitter. Similarly, if y TV set and there is an input for an all-wave antenna, and you have two separate antennas for the MV and UHF bands, use a combining splitter. Both are available at hardware stores.

To connect one antenna to several TV set We use another device called CRAB (consumer cable splitter). It is also sold at hardware stores. This device is best with a collective antenna.

To use an antenna with an amplifier, after connecting it to TV set Plug in the power adapter. Disable it at the same time TV set ohm.

Sound quality from built-in speakers TV is not always high. But even a small machine can be made to sound much better. To do this, just connect it to an external amplifier with columns.

Instructions

Check if u TV:
- DIN jacks for sound recording on a tape recorder;
- headphone jack;
- RCA type connectors with line-out(not the entrance!) sound;
- SCART sockets. If there is at least one of the above, connect the TV to amplifier can.

For a DIN type socket, use the middle pin as the common wire, as the pin on which there is sound signal- either left or right, depending on the date of issue TV... Such a socket is practically not found on stereo TVs. If it is, then the extreme right or left contact corresponds to the right channel, and the one located between it and the common one - to the left.

Connect the cable to the headphone jack together with the plug taken from the damaged headphones. Two white or yellow conductors correspond to the common wire, green or blue - to the left channel, red or orange - to the right. Monophonic TV the channel outputs are connected in parallel. Please note that the sound volume in this case can be adjusted not only on the amplifier, but also on the TV.

For an RCA type connector, use the ring contact as the common, and the pin as the output. If the TV is stereo, the jack corresponding to the left channel is white (same as a monaural TV), to the right - red (and vice versa). Do not try to pick up the audio signal from the yellow connector - only the image signal is present.

On a SCART socket, use pin 4 as a common, from pin 3 remove the signal for the left channel, from pin 1 - for the right. Monophonic TV do not use pin 1.

How the signals are fed to the amplifier depends on which input jacks it uses (DIN or RCA). Apply signals to them as described, respectively, in steps 1 and 3. If the TV is monaural and the amplifier is stereo, connect the inputs of the latter in parallel. If the signal is being picked up from the headphone output, use the amplifier input with the worst sensitivity.

note

Disconnect power to TV and amplifier before connecting.

Useful advice

If the TV does not have sound output, remove the signal from the corresponding output of the VCR or DVD player.

Rarely does a family have just one TV at home these days. But there is usually only one antenna. To connect to one to three, a special device is used - the so-called CRAB.

Instructions

Purchase a CRAB appliance (Subscriber Household Cable Splitter) from a hardware store, which has one input and three outputs. Instead, you can buy a similar imported splitter. The most common among them are Polish and German.

When choosing a splitter, pay attention to the upper border of it frequency range... Due to lack of space, cable operators today often use the most high frequency channels range of UHF. Not every TV can tune in to them, and the manufacturers of splitters may not even be aware of the existence of these channels. The limits of the frequency range are usually indicated on the body of the device or in its instructions.
