Why digital television freezes with a set-top box: analysis of the situation

The quality of the digital television signal depends on the receiving antenna and the construction of the cable transmission network. However, this is not the dominant regulatory factor. Poor quality of digital television, the picture on the last device on the network, the TV screen, can be formed by intermediate equipment. This is a digital set-top box and various signal dividers. Some reasons why digital television slows down can be eliminated yourself.

What does "freeze" mean?

Users combine a number of cases of deterioration in the quality with which digital TV is reproduced into one concept “freezes”. It could be:

• intermittent sound;
• The image is glitchy, the TV shows cubes and is interrupted;
• Digital television with set-top box freezes until the equipment is forced to reboot;
• The system is glitchy, channels are sometimes played, sometimes completely absent.

Failures can occur both when viewing through a set-top box and a TV equipped with a digital tuner.

Signs and causes

To solve the problem, you need to figure out why the TV with a digital television set-top box freezes. Depending on the situation, the problem can manifest itself in different ways:

• a sign indicating image loss appears;
• The television picture freezes from time to time and the sound disappears;
• the sound track is played jerkily, and the image crumbles into colored cubes.

Sometimes the symptoms considered are combined, which leads to assumptions about a malfunction of the TV tuner.

Experts identify several reasons why a digital set-top box for watching television freezes. Let's highlight the main ones:

1. The signal disappears or its level is very weak.
2. Incorrect antenna selection.
3. Equipment malfunction.

If we are talking about the sudden appearance of a malfunction, the reasons may be different. Let's say everything was fine before, but now the smart console slows down and freezes. There are several possible reasons for this:

1. The signal broadcast parameters have changed, for example, the frequency has changed.
2. Preventative or repair work on the repeater.
3. Worsening weather conditions.
4. Incorrect antenna installation.
5. Problems with the tuner software.
6. Damage to connecting cables, etc.

The main reasons why a digital set-top box freezes are discussed above. These are the ones you need to focus on when trying to solve the problem yourself.

Preventative work

If your digital set-top box or TV freezes when watching digital channels from one multiplex, but works fine on others, you should first contact your provider. The situation when part of the user’s broadcast list is played back without problems, but the rest is not, is associated only with improper operation of the transmitting equipment.

Advice! You can find out about preventive maintenance on CETV at rtrs.ru/tv/breaks/ or by calling the hotline 88002202002.

Most often, the provider knows about failures on the channel. But users rarely get acquainted with news on official websites and other information. Perhaps the stated work is going on, and that is why the channels are freezing. One call to the operator will allow you to get rid of many checks, waste of time and effort.

The image crumbles into squares, freezes

I already wrote about this problem here, but I’ll repeat it briefly.

If the image is “square” or there are frequent freezes (precisely frequent, because rare “freezes” on digital TV are quite acceptable), then you should contact the technical support of the provider, and let the specialists there figure out what the problem is, in the subscriber equipment, in the station , or is it simply their quality threshold, so to speak

The antenna is not configured

The situation when digital television freezes from a simple antenna does not necessarily mean that it produces a weak signal. But this is the problem that occurs most often. Happens:

• the antenna is not tuned;
• the device is not designed for current reception conditions;
• passive type antenna.

Important!
You should not lose sight of the fact that the amplifier could break down and the TV set-top freezes due to insufficient signal. First, the wires and contacts throughout the entire cable network of the house are inspected. If damage to the wire, oxides of connecting elements, fixation points is detected, all faults must be eliminated. After this, the antenna is tuned. Indicators of signal quality and strength are displayed on the screen. How to do this is described in detail in the instructions for the set-top box or TV. The antenna is slowly turned, pausing to allow the indicators on the screen to update. Having reached the maximum level (most set-top boxes and TVs operate stably at a value of 60%), the antenna is fixed.

But what to do in a situation where any changes in the antenna position do not lead to an increase in performance above, for example, 40%? The answer is simple. Buy an additional amplifier or change the antenna. In the latter case, the price may be higher, but the effectiveness of installing another receiving device is always more effective.

Useful tips

Avoid twisting the wire into a coil, as well as long sections with horizontal and inclined cable positions; use high-quality cable in these cases.

To avoid interference, the cable must be placed away from power electrical wires and avoid crossing the cable with power lines, and when crossing, make it at a right angle.

Wire the TV cable in one piece; if breaks cannot be avoided, then use special connectors with reliable wire contact and shielding, and not twisted with electrical tape.

The console freezes tightly

If the TV set-top box freezes when playing the owner’s favorite show, you should pay attention to a couple of factors.

1. The device may have overheated below the rated level. The console requires 50 mm of free space between the housing wall and the surroundings.
2. The console's memory is faulty. If the flash memory chips are damaged, the device may simply freeze until it is completely restarted by pulling the plug from the socket.

Similar problems are almost never found on modern TVs. To troubleshoot problems, it is recommended to ensure normal ventilation, try resetting the console to factory settings and updating the software.

Disable Motion Processing

The processors of new TVs are capable of smoothing out sharp, jerky movements in films or TV series. Clear Motion Rate technology combats this phenomenon by creating extra frames (using interpolation) that are “injected” between video frames for a clearer, smoother image. Sometimes this negatively affects the quality - everything looks very unnatural. Therefore, if you are watching a movie, then turn off motion processing or switch to Movie mode.

The console is slow

The concept slows down means that the broadcast is not interrupted. But at the same time, rendering failures may periodically occur on the screen and sound distortion may occur. The first thing you should pay attention to is the firmware version of the set-top box. Using the procedure recommended for the model, the software package is updated to the latest one. This can dramatically improve productivity.

The second situation is somewhat unpleasant. Digital TV, especially in the modern, final release of the DVB T2 standard, requires a fairly large amount of resources to process the picture and generate sound. Therefore, the user's particular set-top box may simply be unable to play video smoothly. The device behaves confidently in static scenes and begins to work jerkily in dynamic, brightly colored scenes. To get rid of this problem, you should buy a modern set-top box.

Software failure

Users accustomed to the fast interface of smartphones and tablet PCs find it difficult to adapt to the “thoughtful” menu of Smart TV. Because of their slowness, consumers often simply ignore 50% of the software's potential and are content only with traditional options, such as watching a movie from a flash drive and connecting TV to a computer. But not all performance problems can be explained by the specifics of the software shell - sometimes its speed drops due to internal software errors. In this case, the TV freezing will most likely be accompanied by pop-up windows signaling conflicts in programs.

• When movies slow down, you need to take a closer look at the screen - perhaps the system will display a message about a software failure. Returning to default settings will not only help get rid of application errors, but will also have a positive effect on the overall performance of the device.
• Updating the system to the latest stable version works in a similar way.
• If no manipulations have any effect, you need to enter the service menu and look for the cause of the malfunction there. Remember that only a specialist can do this quickly and accurately.

TV problems

If a TV equipped with a DVB T2 tuner freezes when watching digital channels, and the antenna is configured, the cable network is checked, the first thing you should pay attention to is the version of the software installed on it. Inexpensive Chinese models simply do not have enough memory and processing power of the processor platform. As a result, the same thing happens as with the prefix. The image on the screen is clogged with cubes.

Advice! The TV can also be reflashed. However, you should not do this yourself. It is better to seek help from specialists, ideally calling a service technician from the model manufacturer.

The main signs of incorrect equipment operation

Possible problems may occur both for one individual channel and for all available multiplexes. Among the most common malfunctions, we highlight the following:

• There is no reception at all; an information sign appears on the screen confirming that the signal has been lost.
• The image on the TV freezes on one picture, the sound disappears, the problem occurs periodically for 5-10 seconds.
• The sound is played jerkily, the picture disintegrates into colored cubes, and when switching to other channels the image is restored, but not always.

Situations often arise in which all of the above manifestations are combined and alternated. A real carousel appears on the screen, and there is no talk of any viewing. To eliminate problems with the reception of DVBT2 standard channels, you will need to accurately determine the reasons for their occurrence.

How to set up channels correctly

Incorrect configuration is often the main reason why channels are not detected. How to set up channels:

1. Having connected the equipment - antenna, set-top box and Wi-Fi adapter if necessary, turn on the TV and select the connection type.
2. Open Settings and find Broadcast.
3. Click on "Auto Configuration" and "Start".
4. In the next window, select the cable as the antenna; next to “Channel Type”, select digital and analog TV, which will allow you to search for all types at once. Next to the mode, select “Full”.
5. Click on the “Scan” button - this will start the search.

The described instructions are suitable not only for Samsung TVs. It can be used when setting up any TV. The only difference is the different names of the menu items.

Why doesn't my Samsung TV find digital channels via antenna or cable?

In some situations, automatic channel search does not bring results, which indicates a malfunction. The error may be hidden in signal reception, connection, installed parameters, software failure, or mechanical damage. Below we will study in detail the existing problems and discuss ways to eliminate them.

Equipment

Make sure that the connected equipment can receive the desired broadcast format. DVB-T2 is a European digital TV standard that has been adopted in our country. That is, if you cannot use the new format and view digital broadcasts, then your equipment is probably outdated and cannot broadcast the accepted DVB-T2 standard.

Antenna

One common cause is a problem with the antenna placement. It is necessary to improve the quality of the received signal. But, when using an indoor antenna for digital broadcasting, the image will begin to ripple or disappear.

Location and external factors are also important. Place the antenna pointing towards the repeater. Additionally, make sure there are no obstacles such as high-rise buildings, trees, etc. If present, move the antenna higher.

Settings

The next reason explaining why the Samsung TV does not see digital channels is the settings. Often, even with the parameters set correctly, the device refuses to detect the “digit”. Solution:

1. Remove the country or select “Other”.
2. Additionally, search for TV channels again by choosing the manual method.
3. If there are no results, reset the receiver settings to factory settings or check for an update.

Cable

Make sure that the cable is intact and that the connection is correct. If the TV previously showed channels without interruption, but now shows no more than 10 broadcasts, then maintenance work has probably begun on the provider’s side. Usually, if the cable or inputs are damaged, the TV shows nothing at all.

Equipment connection problem

Samsung TV can't pick up digital channels? Check that the connection is correct. Take your time to set up the number. Initially, make sure that you have connected all the equipment correctly. For example, a decimeter antenna, which implies a built-in amplifier, must be connected to a receiver, which in turn is connected to the TV itself.

If you have any questions or complaints, please let us know

Search settings

Search settings are often the cause of the problem in question. If the automatic search does not produce results, use the manual search. Don't forget to specify the parameters in the form of connection type, change the country, etc. Use the instructions attached at the beginning of the article.

Software glitches

System failure usually occurs due to user actions. Perhaps you specified incorrect settings in the parameters or made a mistake in specifying the frequency. The culprit may also be the installed software on the set-top box, which the developer has stopped supporting. The solution is to reinstall the software on the receiver.

Additionally, do the following:

• Reset the settings to factory settings and search for broadcasts again.
• Install another firmware on the receiver.

Technical problems on the transmitter side

The last cause of the malfunction may be hidden on the transmitter side, which caused the lack of a signal. Then:

• In the case of cable TV, use a multimeter to check the wiring contacts, including the shield. There may be a break between the transmitter and receiver. Make sure the cables are intact and not damaged. As a last resort, call the company that maintains your home and is responsible for providing access to TV broadcasting.
• When using satellite or terrestrial TV, make sure there are no problems with the provider. Often the official website contains information about scheduled maintenance or possible problems with receiving a signal. Call the operator and clarify the question.

The remote control does not respond

If the remote control does not respond to user actions, then you need to check the following:

• using the original remote control for a specific TV model;
• the On/Off button on the device is turned on;
• remote control functionality;
• TV performance;

Often malfunctions occur due to dead batteries or a cable that has become disconnected. It is noteworthy that lags are observed not only with the image, but also with the sound.

Why does digital television show so poorly: unfavorable terrain

The quality of reception depends on the terrain. If the conditions are very unfavorable, then even rising to a high altitude may not produce tangible results in improving the quality of reception.

The slides in front of you will completely block the transmission of the TV transmitter signal. Since the signal at decimeter waves tends to be reflected from the ground and various objects, to improve the quality of reception, sometimes it is not necessary to raise the antenna to a greater height. A high-gain panel antenna or even a homemade one - the most common - Kharchenko .

It also makes sense to experiment with antenna location and polarization (position in space). A typical wave channel antenna has horizontal polarization. So that then it doesn’t become bad to show the installation of a high mast cannot be avoided

In order to preliminary evaluate the properties of the radio path (the difference in height from the transmitter to the receiving antenna of the TV), there are convenient online services. Of the new ones, Linktest is the most convenient for beginners. You can also use the “classic” online service from Micran.

A few tips to quickly solve the problem

To quickly identify malfunctions in the operation of digital TV, you should use a few tips from professionals.

• Check channels. If problems are typical only for some of them, everything is in order with the equipment, the reasons lie in external factors.
• The complete absence of an image requires a first check of the wires, after which it is worth starting the automatic channel setup. It is possible that the issue is in the settings.
• Checking for updates. In older versions of software, signal decoding is often incorrect.
• Check the information on the channel's website. In case of planned repairs or other outages, information messages are posted here.

It is also worth taking into account the fact that Chinese TVs do not connect very well with set-top boxes, especially after the update. In this case, it is better to purchase a new, more modern TV.

In situations where none of the methods helps, and neighbors have no problems with showing channels, the reason is a serious malfunction. In this case, you will need to call a specialist and possibly change the equipment.

What other difficulties are there with setting up?

What to do if digital TV shows poorly, with interference

❶

Check which channels should be broadcast in your region

The quality of reception is greatly influenced by the equipment (TV, antenna, amplifier, etc.), the terrain and the location of the house relative to the broadcast tower. If your house is located in the middle of a forest (relatively speaking) and the TV tower is very far from you, then, alas, you shouldn’t expect good reception (as before)...

• What to do if the TV does not show well on the antenna

In general, to begin with, what I recommend doing is to check on the official website https://rtrs.ru/ which of the digital TV channels are available in your area. Usually these are 2 digital packages RTRS-1 and RTRS-2, which include 20 free channels: First, Russia, Match!, NTV, 5th, TVC, Zvezda, Spas, TV3, TNT, Zvezda, Friday!, Muz- TV, etc. (see screenshot below).

What channels are shown in my area

In addition, on the same site you can view coverage areas and broadcast frequencies specifically for your region. Despite the fact that in June 2021 Almost the entire country should switch to digital broadcasting - there are still corners where this is not the case...

❷

What's with the cable and plug?

The cable has a very strong influence on the transmission of the received signal by the antenna. And for many people, his condition leaves much to be desired, not even the best (but the best?).

In general, if you encounter any interference when setting up digital TV, be sure to check the condition of the cable and plug. Are there any twists on it, is it intact at all (sometimes pets chew it up).

• Why does a 4k TV show analogue channels poorly?

Twisting the cable...

In addition, try to avoid various doubles, tees, etc. Ideally, for good reception, you should have a solid cable running from the antenna to the TV without any twists. If it is necessary (for example, it is not possible to replace the cable with a new one), then it is better to purchase a special one for this purpose. F-socket. (more details about correct cable connection).

❸

Pay attention to the antenna

The biggest influence (besides your location) on signal reception is the antenna (and its placement, but more on that next point). As a rule, if your TV tuner (receiver, TV) came with an antenna, it is small and weak: it can provide normal reception if you are no further than 10-15 km from the television tower (and there are no antennas in front of your house). then serious obstacles).

Antenna from a TV tuner (example)

That is why I would recommend abandoning such an antenna (see example in the photo above). Even a homemade antenna made from old aluminum cans can provide much better reception.

An example of a homemade antenna made from aluminum cans

If such conventional antennas do not receive the signal well, I recommend paying attention to outdoor antennas with an active amplifier (for DVB-T2). Why exactly this? The fact is that indoor antennas receive signals much worse than outdoor ones (especially when it comes to a country house). Well, active amplification will significantly improve the received signal (note that there are also passive amplifiers - they are usually somewhat weaker).

• How to connect to a TV and set up a digital set-top box for all channels

❹

A few words about the antenna location

The quality of the received signal can vary greatly depending on the antenna placement. Even weak indoor antennas in one place of your apartment can catch a signal, but not in another.

We can recommend trying to connect the antenna to the TV, and then experiment with its location: first place it near the window in one room, then in another, etc.

Of course, using an external antenna will significantly improve the reception level. Moreover, pay attention to one point: installing the antenna 2-3 meters higher than the level of trees and buildings in the immediate surroundings can give amazing results!

❺

Weak signal due to bad weather...

If there is heavy rain outside the window, thunderstorm, blizzard, etc. and so on. - all this can affect the reception of terrestrial DVB-T2 television. At this time, the broadcast is usually jerky and intermittent (and nothing can be done about it).

Storm…

By the way, in the case of ordinary classic television, when the signal deteriorated, the picture was distorted (red horizontal stripes appeared), but it was still watchable. With digital television: when the signal level decreases, it becomes impossible to watch the broadcast?... And in this regard, I don’t understand what the advantage of the new broadcast format is...

❻

You can connect cable TV

If all of the above does not help, then as an option you can connect either cable TV or install a satellite dish. Whether you live in a city or a rural area, one of the connection options will almost certainly be available.

By the way, it should be noted that the cost of such equipment has decreased significantly compared to what it was 10-15 years ago. Moreover, now some companies provide equipment for free, provided that you use it for 2-3 years. In general, there are options...

❼

You can watch TV on the Internet

Well, I can’t help but note that with the development of networks in our country, many users have the opportunity to watch TV via the Internet. Moreover, for this it is not at all necessary to be the owner of high-speed Internet access (the main thing is that the connection is stable and not “interrupted”).

I have a separate blog post on how to set all this up, the link to it is below.

Paradoxically, the country’s main channel is associated with a huge number of complaints about poor-quality “pictures”. Moreover, as a rule, claims come from owners of expensive and widescreen 4K TVs. Why does this happen and how can the situation be corrected?

Despite the fact that online it has long been possible to watch most of the top-rated programs, such as Men's and Women's First Channel , Evening Urgant, Let's Get Married, both recorded and live, most viewers of the first button use the old fashioned way for this TV. If the image leaves much to be desired, is constantly distorted or is not saturated enough, then you can try changing some of the settings in it.

On each TV model, these settings are performed in different ways. As an example, we use LG TV with the WebOS operating system
