The strength and quality of the tricolor signal is constantly changing. Antennas: what, where and how? What you should pay attention to

All tips

If both scales are filled to at least 70%, and the Info Channel still displays the message “No Signal,” return the receiver settings to the factory settings.

To do this, press the “Menu” button, then “Settings” or “Settings” or “Applications”, select “Factory settings” and press the “OK” button. After confirming the reset, the receiver will reboot and the Wizard will be launched initial setup. In the Installation Wizard, specify the satellite TV operator and select the region where your equipment will be installed, if it is in the drop-down list. If after this the channels are not found (or not all channels are found), you need to re-configure the antenna to receive a signal from the satellite.

If it was not possible to configure the successor, then

You need to adjust the antenna to more confident reception signal. You can do this yourself or contact

On one/several channels, the “Tricolor TV Info Channel” shows

Check the strength of the received signal from the antenna

To do this, on the Tricolor TV Info Channel, double-click on the red function button on the receiver remote control (“F1”, “i” or “INFO”, press again if necessary green button on the remote control). An expanded information banner window will open. In the window that appears, two scales will be displayed at the bottom - signal strength and signal quality. For stable signal reception from the satellite, the scales must be filled to at least 70% (visually - three-quarters).

1. Both scales are 70% filled or more

If the Infochannel shows, but the image is missing only on some channels of the paid service, this may be due to a change in the channel broadcast parameters to optimize satellite capacities. In such situations, channels with old broadcast parameters may be stored in the channel list on your receiver. You need to update the channel list. To update the channel list, press the “Menu” button on the receiver’s remote control and in the “Main Menu” select “Search for Tricolor TV channels.”

2. One or both scales are less than 70% filled

You need to adjust the antenna for more reliable signal reception. You can do this yourself or contact

The screen displays "Empty list"

Check the strength of the received signal from the antenna.

To do this, press the red function button on the receiver’s remote control twice (“F1”, “i” or “INFO”; if necessary, also press the green button on the remote control). An expanded information banner window will open. In the window that appears, two scales will be displayed at the bottom - signal strength and signal quality. For stable signal reception from the satellite, the scales must be filled to at least 70% (visually - three-quarters).

1. Both scales are 70% filled or more

Press the “Menu” button on the remote control and select “Search for Tricolor TV channels.” Then click the “OK” button and confirm the start of the channel search. Wait until the search for TV and radio channels is completed (the screen should display Announcement) and save the found TV channels.

2. One or both scales are less than 70% filled

Reset the receiver settings to factory settings.

To do this, press the “Menu” button, then “Settings” or “Settings or “Applications”, select “Factory settings” and press the “Ok” button. After confirming the reset, the receiver will reboot and the Initial Setup Wizard will be launched. In the Installation Wizard, specify the satellite TV operator and select the region where your equipment will be installed, if it is in the drop-down list. If after this the channels are not found (or not all channels are found), you need to re-configure the antenna to receive a signal from the satellite.

If it still doesn’t show, then you need to adjust the antenna for more reliable signal reception. You can do this yourself or contact.

Seal

This is not a very common malfunction, and you can’t even call it a malfunction, meaning when the quality of the received signal fluctuates DVB signal T2. Most often this is due to the position of the cable from the antenna to the TV, reception conditions and a number of other reasons. Why this happens is simply incomprehensible to an inexperienced user in such matters, and he can explain this behavior of the tuner as a malfunction of the set-top box or antenna, but that is not the point. However, let's take things in order.

Causes

The intensity with which the dvb-t2 signal jumps depends on the height at which the cable has such a horizontal section and how long it is; if it is located close to the ground, then the influence of interference is minimal. It is clear that the longer such a section is, the more the useful signal will be suppressed. To avoid this, place the antenna close to the set-top box; using a high-quality cable also helps.

The digital TV signal also begins to jump when it is tilted, for example when it descends from the ridge of the roof to the wall. It is worth noting that there is a known case when, with an inclined cable, the receiver showed for quite a long time after tuning, and with the onset of summer and hot weather, the signal level began to change abruptly from 0 to 100, and the quality signal remained at 5%.

There have been cases in practice when, in urban conditions, with a nearby tower located, an active indoor antenna was used to receive the first and second multiplex. The signal arriving at the tuner was very large, which led to the protection being triggered and, as a result, the signal began to jump on the digital tuner.

There were also opposite cases when the signal was artificially lowered. This refers to obstacles in the form of buildings or trees. Moreover, if there is a tree between the antenna and the tower, the reception is excellent in winter, but in summer the foliage dampens the signal and jumps in its level also occur. In this case, it is enough to move the antenna. By the way, for this reason there is a signal failure on satellite TV, installed plate It was showing correctly for several years and suddenly glitches began to occur, the picture crumbled into squares. It turned out that the tree had grown over the years and began to block the dish from the satellite.

There are many nuances here and they can have an impact - weather, cable quality, tower location range (signal strength), so you need to understand each case when the signal starts to jump when receiving or setting up T2, individually, and no matter what set-top box you have World Vision, Rolsen, etc..

Avoid twisting the wire into a coil, as well as long sections with horizontal and inclined cable positions; use 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.

Tricolor satellite television has long been popular among large number TV viewers - and all thanks a large number channels and broadcast quality. But even with the latest technology Such a nuisance as a lack of signal may occur.

What to do if the inscription on the Tricolor “No signal” appears on only a few channels, while the rest show

If the signal is lost on only a few channels, you will need to update their list. To do this you will need:

Disconnect the receiver from the power supply for about a minute, then connect it and wait until the receiver comes back on. working condition, and then switch it to a scrambled channel.

If there is no signal on Tricolor-TV again, search for channels, which can be done using the remote control for the receiver. Enter the menu, then search for “Tricolor-TV” channels, then click OK, then the yellow “Done” button and finally “Exit”. Next, the search for channels will begin. During the search, two buttons will be displayed on the screen - “All Radio” and “All TV”. At the end of the search, a window will appear with the number of TV channels found.

Be sure to save the detected TV channels. To do this, click the “OK” button. After this, the receiver should turn on to Tricolor-TV.

What to do if the inscription on the Tricolor “No signal” appears on all television channels

If the signal disappears on all TV channels, this indicates its low level. Then you will need to check the connection between the cable and the receiver, its reliability and the integrity of the connections at the connector connections.

If the connection is still correct and there is no damage to the cable, and there is no signal on the Tricolor, then the antenna will need to be configured manually. To do this, it is best to contact a regional dealer to call a specialist to your home.

To adjust the antenna yourself, you need to move the antenna very slowly, one centimeter at a time, fixing it for 5 seconds in each position until an image appears on Tricolor-TV. The strength and quality of the signal can be checked using the information banner located on this TV channel by pressing the “i” button twice. In this case, the signal and quality scale will be displayed at the bottom of the screen (quality on the right and strength on the left). To view Tricolor-TV channels, these two scales must be filled at least 70%, only in this case the viewing will be stable.

What to do if the inscription “No signal” on the Tricolor continues to appear

In most cases, the procedure described above helps, but sometimes you have to resort to more radical measures, requiring a factory reset of the receiver. To do this, you need to turn on the receiver. On the remote control, after pressing the “Menu” button, the entire receiver menu will be displayed.

Using the "Down" and "Up" arrows located on remote control control, you need to go to the “Installation” item. Next, to enter the submenu, press the “OK” button and enter the required PIN: 0000.

In the next submenu that opens, use the arrows to select “Factory settings” and click “OK.” Then press the “F1” button and confirm the reset existing installations, then wait a minute for the process to finish.

A “Next” button will appear in the Settings Wizard. Click “OK” again, and repeat this in each window that appears, without changing the value, until “Search for Tricolor-TV channels” appears.

After graduation automatic search The number of detected Radio and TV channels will be displayed. And the “Done” button will be available to click. Press the “F3” button, which will allow you to save all found channels. Enjoy watching high quality TV!

From this article you learned what to do if the message “no signal” appears. Tricolor-TV will now give you only one pleasure, because you will be able to watch the most interesting TV shows.

In Russia, the largest digital television provider is Tricolor. Most subscribers are familiar with the situation in which a message about no signal appears on the TV screen. Message "No signal" should not be a reason for serious worries and worries. The inability to watch a channel in most cases is actually caused by a lack of signal, and the reasons for this situation are intuitive and can be eliminated by the subscriber independently.

What are the reasons

First you need to understand causes, causing problems with signal transmission. All problems in which the dish signal disappears can be divided into two large groups:

writing an error message TV may be due to external reasons, which do not depend on the subscriber’s receiving equipment;
TV is capable of writing an error message due to internal reasons, which are caused by equipment malfunctions or are associated with settings failures.

External causes that can cause problems with signal transmission include external influences in the form of wind, snow, rain, when exposed to which the TV begins to show poorly. This group includes the need to carry out all restoration work in case of accidents, when the signal begins to disappear and the Tricolor stops showing. The signal begins to disappear during periodic maintenance work by the operator.

First steps if there is no signal

Problems may not be related to work satellite dish, since in some cases the message may be shown by the TV itself. It is necessary to find out the reason why the TV channel stopped working. To find out the influence of the TV settings, you need to use the Tricolor TV remote control press"OK" button. If the general list of channels is not displayed on the screen, then the TV settings have failed. To resolve, you need to re-configure the TV by selecting the connection input satellite receiver.

It is recommended to disconnect the signal receiver from the power supply for about 1 minute. Turn on the receiver again and wait until it enters operating mode. Check what's on the desired channel the message about no signal disappeared.

If the situation has not changed, then you need to check the number of channels on which the “No Signal” entry appeared. If the error message is not displayed on all channels, but is shown only on one channel, then it is enough to update the list of TV channels. To do this you need to do a number of simple actions:

select the “Menu” item and press the “OK” confirmation item;
Answer “Yes” and “OK” to the warning message about updating channels.

Updating channels may take a long time, so don't worry. Once the update is complete, a window will appear on the screen indicating the total number of channels found. You need to save the settings.

If the message "No Signal" appears on all channels, then the reason must be search in the operation of the equipment.

Why is there no signal on Tricolor TV

To solve the problem of no signal, it is necessary to perform a number of actions, the implementation of which will give 100% result:

Before finding out whether there are technical problems with the equipment, it is worth checking for natural causes in the form of a lack of broadcasting channels. It is likely that in this moment Preventative work is being carried out. According to functional responsibilities the operator is obliged to inform the subscriber about planned maintenance work several days before the start of work. Most subscribers ignore incoming messages or the information does not reach them for certain reasons.

Check information about the event preventive work you can:

Problems of this nature are usually resolved within 10-20 hours. Information about the occurrence of an unforeseen situation must be posted on the official website of the provider.

Absence messages about preventive maintenance and unforeseen situations means that the root cause must be looked for elsewhere.

Technical problems

You need to check the cable connection from the receiver. For this necessary:

check if there are breaks or damage on the cable;
check the tightness of the contact threads

You need to find out if there are breaks or any damage on the cable. Visual inspection may reveal obvious damage. If there are none, it is recommended to use a tester and check for hidden problems.

If problems are identified, the cable must be replaced. If it is not possible to completely replace the cable, you can eliminate the break and connect the cable parts. This requires a special connector and two F connectors. You need to do the following actions:

cut the cable where the break is detected;
strip the braid;
screw the connectors onto the cable;
secure firmly with a connector;
strengthen the connection by wrapping a layer of electrical tape over it.

If no damage is detected in the cable, then it is necessary to check the tightness of the F-contact threads.

No signal may be caused by a faulty receiver. To check the device, just connect it to a working antenna. To do this, you can contact your friends or relatives, neighbors who have the Tricolor. If a signal appears, then the cause of the breakdown must be sought in antenna.

A negative test result in the form of no signal indicates a breakdown of the receiver. In most cases, the tuner responsible for receiving the Tricolor signal fails. In this case, the receiver must be taken for repair to service center.

Antenna malfunction

Very often, antenna malfunction occurs as a consequence of exposure to unfavorable natural conditions such as strong winds and heavy rainfall. In this case, as a rule, the side connections that hold the antenna in a certain direction become loose. Even a deviation of the antenna by 1-2 degrees leads to the fact that the satellite signal passes by it and problems occur in viewing Tricolor TV channels. For elimination problems needed:

prepare wrenches for tightening the nuts;
inspect the place, providing possible sources dangers;
stretch all antenna connections;
tune the antenna by pointing the antenna in a certain direction until a clear signal is received.

When trying to change direction, each position must be fixed for 3-5 seconds. It is recommended to use the help of an assistant when setting up, so when setting up a specific rotation to receive a signal, you need to check its quality. The signal quality can be checked by calling up the banner by pressing F1 on information channel. A scale of signal quality and strength is displayed at the bottom left of the screen. To be able to view stable and high-quality image TV channel, both scales should reach 70%. When a good signal is received, you can stop working.

If it is impossible to set up the antenna yourself, you must seek the help of a specialist by calling him to your home. The technician will configure the antenna using the horizontal scanning method.

Converter problem

In most cases, the cause of the “No Signal” message is a broken converter. The difficulty of diagnosing lies in the fact that it is very difficult for the subscriber to determine whether the error in receiving a signal is the result of a broken converter or whether it was influenced by other factors. It is impossible to visually determine whether the converter is broken.

For checks must be completed the following actions:

The subscriber will most likely not be able to solve a problem of this nature on his own and will have to seek the help of a specialist.

What you should pay attention to

Don’t panic when a “No Signal” message appears on your TV screen. It is not recommended to randomly press the remote control buttons repeatedly while trying to achieve a result. Try to calmly analyze the situation and try to find out the reason possible problems.

Remember, that when trying to search and update channels, you cannot disconnect the signal receiver from the power supply. Otherwise, the equipment may be damaged.

You should not waste time and effort trying to fix a technical problem yourself. In most cases, it is much easier and faster to contact a specialized service center than to do the work to eliminate the causes yourself. Service specialists are able to work in a fairly short time frame and will do everything necessary work By liquidation Reasons for no signal:

equipment setup;
replacement faulty equipment;
software update.
