No signal - Tricolor TV: what to do if the signal level has disappeared, diagnostics

The reasons why there is no signal from the Tricolor satellite dish

The occurrence of errors in the broadcasting of television channels is always unpleasant, but when there is a complete absence of broadcasting, then this is already a cause for concern. A completely logical question arises - why is there no signal on Tricolor TV?

When an error is displayed on the TV screen, accompanied by the inscription "No signal", this occurs not due to the lack of funds on the balance, but due to a number of other factors.

Specialists in the field of satellite equipment distinguish two main groups of reasons leading to the fact that there is no video on Tricolor TV:

• external, not related to the operation of the equipment;
• internal, arising from a malfunction of the receiver or antenna.

Among the external reasons why there is no signal on all Tricolor channels are the following factors:

• exposure to weather conditions;
• preventive work;
• obstacles to the passage of the signal from the satellite to the receiver.

Internal problems that cause malfunctions in the operation of equipment, accompanied by the fact that "Tricolor TV" writes "No signal", the following factors can be considered:

• incorrect selection of the video signal source on the receiver;
• damage to the connecting cable;
• incorrect initial settings;
• breakdown of the receiver or receiver;
• breakdown of the antenna.

It is often difficult to eliminate internal problems on your own and you need to contact the service technical support to receive qualified assistance and to accurately identify the reason why "Tricolor" writes "No signal ".

Weather

One of the most frequent reasons why Tricolor TV does not work is weather conditions. The satellite, which carries out broadcasting and has the designation "Express-AMU1", is located in a geostationary orbit, which lies at an altitude of over 34 km almost above the equator.

It turns out that in order for the signal to reach the subscriber's antenna, it must first reach the operator, be sent back to the satellite, and only then sent to the user. The receiving frequency ranges from 10.5 to 12.5 GHz.

The radio signal is sensitive to interference caused by atmospheric phenomena such as snow, rain or hail. Bad weather can cause weakening of the signal, and in some cases, cause complete loss of signal.

Another reason why "Tricolor" does not search for channels is mechanical interference in the form of trees or bushes that have grown under the window. In this case, the solution to the problem will be the elementary elimination of the interfering factor or the movement of the antenna to another place.

If the reason why Tricolor TV is not working today is in bad weather outside the window, then nothing should be done, but you just need to wait for the weather condition to improve.

Software glitches

Much more serious will be the problem caused by software malfunctions in the equipment. Since all satellite receivers operate under the operating system, periodically freezes may occur when the Tricolor TV receiver does not work and simply does not respond to any actions user. Also, the drivers necessary for the normal functioning of the tuner can "fly off". In this case, the following steps can be used to fix the problem:

• complete reboot of the receiver;
• rollback to the factory settings of the equipment;
• tuner flashing.

FOR YOUR INFORMATION!

You can carry out the update procedure yourself or give the device to the service, but then the procedure will be paid.

How to diagnose why Tricolor TV does not show

To understand what to do when the signal on Tricolor TV disappears, you should initially carry out a number of diagnostic measures.

When an inscription is displayed on the screen of the TV receiver, notifying about the absence of a signal, the first thing to do is to try to check the correct selection of the input signal source. Depending on the model of the TV receiver, this action can be performed by pressing the Input or Source key. Further, after entering the corresponding menu, you should select the input to which the antenna is connected.

The second step for self-diagnosis is to check the correct operation of the receiver itself, namely, the presence of power.

FOR YOUR INFORMATION!

Sometimes it happens that the power indicator works, but the receiver itself, in fact, does not. In this case, pull the plug out of the socket and reconnect it after a while.

When looking for the cause, you need to make sure that there is no broadcast on all channels. If only one program is not broadcast, then there is a high probability that technical work is simply being carried out or that the malfunctions are caused by problems on the part of the operator. But if even the info channel is not displayed, then the reason is in the malfunction of the receiver or antenna.

What to do if there is no signal on Tricolor TV for technical reasons

If you identify a problem, you can try to fix it yourself. In most cases, the implementation of measures to solve the lack of a signal does not require the help of a specialist.

Elimination of insufficient rigidity of the antenna and cables

One of the reasons for the lack of signal reception is damage to the antenna cable. Most often, this is typical for old equipment. Since the wires are outside, damage to the outer insulation of the coaxial wire is observed over time. Microcracks form on it, which leads to the accumulation of moisture, corrosion of the inner coating, and deterioration of the signal until it is completely lost.

There is also the possibility that if there is a direct connection between the cable and the receiver, water can penetrate into the tuner connectors, causing damage to it. Oxidation of the connectors is not uncommon. To diagnose and eliminate this trouble, you need:

• check the cable for damage. If they are found, it is necessary to replace the wire, in whole or in a certain area. Splicing two cables can be done using a special connector;
• check the junction of the wire and the receiver for the formation of traces of oxidation or rust. In this case, you need to remove a couple of centimeters, re-strip and use a connector with a special seal for outdoor use.

Tricolor writes that there is no signal: what to do if the problem is in the converter

Physical problems with the converter are some of the causes that can cause no signal. This happens quite rarely, but you should not exclude such a factor. There are three reasons leading to the failure of this part:

• a lightning strike, which forms a strong hotbed of static voltage, disabling not only the converter, but also all electrical equipment;
• drops in mains voltage. In the absence of a stabilizer, there is a high probability of board burnout;

FOR YOUR INFORMATION!

If the voltage jump in the final source exceeds 240 V, then more than 18 volts will go to the converter, which will lead to its failure.

• solar interference. During the calendar year, several periods are distinguished when the focusing of bright sunlight, which can lead to overheating or even melting of the transmitting part of the satellite antennas. In this case, you will need to replace the converter. The Tricolor TV website presents a full range of products with prices and specifications.

It is not possible to check the converter at home. Therefore, if there is a problem, it is in it that you will have to contact the specialists.

What to do if the receiver is broken

Everything here is very clear and simple. If the receiver stops turning on, or the display shows incomprehensible symbols, and the equipment does not respond to pressing the buttons on the remote control, the reason is the receiver's breakdown.

There are only two solutions: try to reflash the receiver (which you can do yourself) or replace the motherboard (only in a service workshop). In the latter case, the master will diagnose and identify the maintainability of the equipment. In the worst case, you will need to purchase a new set-top box.

What to do if a problem occurs when the input signal is insufficient

The first action that is recommended when a warning message appears indicating the absence of a signal is to check its quality and strength. Thus, it will be possible to reduce the number of possible answers to the question of what is happening with Tricolor today.

Checking the signal quality of the operator "Tricolor"

You can check the quality of the incoming signal using the remote control from the receiver. The choice of the button to enter the corresponding menu will depend on the model of a particular receiver (GS, DTS, DRS, HD). Most often, you will need to press one of three:

• i;
• F1;
• INFO.

Sometimes, as confirmation of the action, you will need to additionally press the green key on the remote control.

Next, an information board will be displayed on the TV screen, on which there are two scales. They display the level of the incoming signal and its quality. All corrective actions will depend on the indication. To ensure normal broadcasting, a signal level of at least 80% is required.

Otherwise, you will need to check for physical damage, correct antenna alignment, and proper operation of the receiver.

Setting up a cymbal

If all physical parts are intact, and the equipment is operating normally, the reason for the lack of signal may be hidden in the incorrect installation of the antenna. It is recommended to carry out the settings together: one person will change the angle of rotation, the second at this moment observes the change in the signal.

Rotate the plate slowly, changing the angle at a time no more than 10 °. Between actions there should be a fixation of the position for 10–20 seconds. During these pauses, the level is checked. The actions are repeated until the strength of the incoming signal reaches about 90%.

FOR YOUR INFORMATION!

Before tuning the antenna, it is recommended to clear it of ice in winter or debris in summer. Also, these activities are recommended to be carried out in clear weather.

What to do if only a few channels refuse to work

If only some channels are refusing to broadcast, the problem may be software related. In this case, you may need to reset the receiver to factory defaults. The second solution, when the list of Tricolor regions is not available due to the operator changing the broadcasting frequencies, involves re-tuning the channels.

How to reset "Tricolor" to factory settings

You can reset the settings yourself. To do this, you need to act according to the following scheme:

• enter the receiver menu;
• select "Applications" or "Settings" (on older models);
• go to the subsection "Factory";
• confirm the action by entering the receiver's pin-code or by pressing the OK button.

FOR YOUR INFORMATION!

By default, the factory code for confirming user actions is 0000, which works if no one has set a user password.

After completing the procedure, you must wait some time to complete the hardware reboot. The first thing that the user will see will be the setup menu, in which you will need to set the date, time, region and other necessary data. When the setup is complete, the receiver will automatically scan for frequencies and scan for channels. The list that appears must be saved.

Updating the list of TV channels

The reason for the lack of broadcasting at a normal signal level may be incorrect channel tuning. This issue is resolved by updating the list. The sequence of actions is as follows:

• disconnecting the receiver from the network;
• turning on the receiver while waiting for it to switch to operating mode;
• transition to the channel where the error appeared;
• go to the receiver menu, item "Channel search";
• confirmation of the action by pressing the "OK" button.

The receiver will scan the available TV channels for a couple of minutes and form a new list. It must be saved in the device memory.

The appearance on the TV screen of the message "No signal" is not a sentence. With correct diagnostics, the problem can be solved independently without involving the technical support service of the broadcast operator. You can see the instructions for resuming broadcasting of Tricolor TV again in the presented video.
