No -Trikolor TV signal: what to do if you lost the signal level diagnostics

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

The occurrence of errors during broadcasting of TV channels is always unpleasant, but when there is a complete lack of translation - it is already a cause for concern. There is quite a logical question - why there is no signal at the "Tricolor TV"?

When the TV displays an error, followed by a "No Signal" sign display, there is not because of lack of funds on the balance sheet, but because of other factors.

in the field of satellite equipment Experts identify two main groups of causes that lead to the fact that there is no video on the "Tricolor TV":

• external, not work-related equipment;
• internal, arising due to problems of the receiver or the antenna.

Among the external reasons why there is no signal at all "Tricolor" channels include the following factors:

• the impact of weather conditions;
• preventive maintenance;
• obstacles for passage of a signal from the satellite to the receiver.

Internal problems that cause problems in the functioning of the equipment, accompanied by the fact that the "Tricolor TV" writes "No Signal", the following factors may be considered:

• incorrect selection of the video source to the receiver;
• damage to the connecting cable;
• incorrect initial setting;
• breakage receiver or receiver;
• Antenna failure.

Eliminate internal problems on their own often it is difficult and required to address service technical support for qualified medical care and accurate detection of the reasons why the "Tricolor" writes, "No signal. "

Weather

One of the most frequent reasons, why does not work "Tricolor TV" are the weather conditions. A satellite broadcasts and having the designation "AMU1 Express", located in a geostationary orbit, which runs at a height substantially greater than 34 km above the equator.

It turns out that the signal can reach the subscriber antenna, it must first reach of the operator, to be sent back to the satellite and then sent to the user. receiving frequency varies from 10.5 to 12.5 GHz.

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

Another reason for the "Tricolor" does not search channels are mechanical interference in the form of trees or shrubs, grown under the window. In this case, the solution is an elementary elimination of interfering factors or antenna movement to another location.

If the reason why, today, does not work "Tricolor TV" - in bad weather outside the window, then you should not take anything, and you just need to wait for better weather conditions.

software failures

Much more serious is the problem caused by software malfunctioning of equipment. Since all of the satellite signal receivers operate under the operating system periodically there may be unresponsive when the receiver is "Tricolor TV" is not working and simply does not respond to any action user. Can also "fly" Driver needed for the proper functioning of the tuner. Ways to fix this problem, the following steps could be in this case:

• a complete reboot of the receiver;
• roll back to the factory default settings of equipment;
• flashing tuner.

How to diagnose why not show "Tricolor TV"

To understand what to do when lost signal on the "Tricolor TV", should initially conduct a series of diagnostic measures.

When displayed on the screen telereceiver label to indicate the absence of a signal, the first thing you can try to check the correct selection of the input source. Depending on the model, the television receiver, this operation can be done by pressing the Input or Source button. Further, after being hit in the corresponding menu, select the input to which the antenna is connected.

The second action of self-diagnosis is to test the proper operation of the receiver itself, namely - the availability of power.

When searching for the reasons you need to ensure that no broadcast on all channels. If not broadcast only one program, then it is likely that just under maintenance or malfunction caused by problems on the part of the operator. But if not displayed even Infochannel, the reason - in the malfunction of the receiver or the antenna.

What to do if "Tricolor TV" no signal for technical reasons

In identifying the problem, you can try to remove it yourself. In most cases, conduct activities to address the lack of a signal does not require professional assistance.

Elimination of insufficient stiffness and cables mount antennas

One reason for the absence of signal reception antenna cable is damaged. Most often, such a characteristic of the old equipment. Since the wires are on the street, with time there is damage to the outer insulation of the coaxial cable. It microcracks, which leads to the accumulation of moisture, corrode subcoating and signal deterioration until its total loss.

There is also the possibility that if there is a direct connection cable and receiver, water can penetrate the tuner connectors that lead to damage. It often happens, and oxidation of connecting jacks. To diagnose and resolve this trouble is required:

• check cable for damage. When they are detected require replacement of the wire, in whole or in a particular area. Two cables can be spliced ​​by means of a special connector;
• to verify the place of connection wires and the receiver for the formation of traces of oxidation or rust. In this case, a couple of centimeters you want to remove, to re cleaning and use connector with a special seal for outdoor use.

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

The reasons that may cause the lack of a signal are physical problems in the converter. This is quite rare, but ruled out such a factor is not necessary. There are three reasons that lead to the failure of this part:

• lightning, which forms a strong static focus voltage, incapacitating not only the converter but also all electric appliances;
• power-line surges. In the absence of the stabilizer it is likely burn board;

• solar interference. Throughout the calendar year, allocate some periods when there is bright focus the sun's rays, which can lead to overheating or even melting of the transmitter portion of the satellite antenna. In this case, the converter needs to be replaced. The site "Tricolor TV" is a full range of prices and technical characteristics.

To verify the converter at home is not possible. Therefore, if the problem is in it will have to turn to specialists.

What if the receiver has broken down

Here everything is clear and simple. If the receiver is no longer switched on or the display shows strange symbols, the equipment does not respond when you press buttons on the remote, the reason lies in the failure of the receiver.

There are only two options: try to flash the receiver (which can be done by yourself) or to carry out the replacement of the motherboard (only in service center). In the latter case, the wizard will diagnose and identify the maintainability of the equipment. In the worst case, it requires the purchase of a new set-top box.

What if the problem occurs when there is insufficient strength of the incoming signal

The first action is recommended when a warning label indicating the absence of a signal, is to check the quality and strength. Thus be able to reduce the number of possible answers to the question that today with the "Tricolor".

Checking the quality of the signal operator "Tricolor"

To verify the quality of the incoming signal may be by remote control from the receiver. Selecting the button to enter the corresponding menu will depend on the specific model of the receiver (GS, DTS, DRS, HD). Most often you need to press one of the three:

• i;
• F1;
• INFO.

Sometimes, as a confirmation of an action is required in addition to press the green button on the remote.

Next, the TV will display the information board, on which there are two scales. They displayed the level of the input signal and its quality. All the corrective action will depend on the evidence. To provide a normal broadcast signal requires at least 80%.

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

Setting the plate

If all the physical parts in one piece, and the equipment is operating normally, there is no signal the reason may be hiding in the improper installation of the antenna. Conduct adjustment is recommended together: one person will change the angle of rotation, the second at this point to observe the change of the signal.

Turn the plate should be slowly changing the angle at a time not more than 10 °. Between steps must be locked in position for 10-20 seconds. In the pause is held level check. The actions are repeated until reaching the incoming signal strength of about 90%.

What if refuse to work only a few channels

If you refuse to broadcast only a few channels, the problem may be software-related. In this case, you may need to reset the receiver's settings to the factory settings. Second Embodiment solutions, when a list of regions "Tricolor" unavailable due to change of broadcasting frequencies operator assumes channel reconfiguration.

How to reset the "Tricolor" to the factory settings

Reset settings can be yourself. This requires action in the following way:

• enter the menu of the receiver;
• select the "Applications" or "Settings" (on older models);
• go to chapter "factory";
• confirm the action by entering the receiver's PIN code or by pressing the OK button.

After the completion of the procedures necessary to wait some time to complete restart of equipment. The first thing the user sees is the set-up menu, which is required to set the date, time, region, and other necessary data. Upon completion of adjusting the settings, the receiver automatically conduct scans and frequency search channels. A list must be preserved.

Updating the list of TV channels

The reason for the absence in the normal broadcasting signal level may become incorrect adjustment channels. This problem is eliminated by updating the list. Proceed as follows:

• off the receiver from the mains;
• switching the receiver to move its expectation of the operation mode;
• switch to the channel where the error occurs;
• the transition to the receiver's menu option "Channel Search";
• confirm the action by pressing the "OK" button.

Receiver for a couple of minutes to conduct scans for available channels for broadcast and will form a new list. It must be stored in the device memory.

The appearance on the television message "No Signal" screen - this is not a sentence. With the correct diagnosis of a solution can be carried out independently without the involvement of technical support service operator. Once again, see the instructions for the resumption of the broadcast "Tricolor TV" can be presented in the video.
