Whatever many researchers say, the Internet has not been able to fully replace television. Modern devices allow you to get the maximum image quality, but it was not possible to completely get rid of various problems when watching TV shows. And the owners often wonder why the TV began to show badly. The following factors can create various interference and interference:
- weather conditions in case of thunderstorm, heavy cloud cover, fog or wind;
- too much distance from the receiver to the signal source, which is especially important outside the city;
- capabilities of the device itself, since all TVs differ in their characteristics;
- device setup specifics.
This article describes the main causes of image problems and how to fix them.
Prevention
It happens that the TV channel interrupts the broadcast in order to prevent and maintain its equipment. In the case when the rest are working properly, it is worthwait for the repair work to be completed, and broadcasting will resume. Also, many channels use a characteristic screensaver during technical breaks.
In some cases, the lack of a signal may be due to malfunctions on the provider's side. To confirm this, you can check with your neighbors if the television is working for them, or immediately call the technical support line. It is also worth checking if the money on your personal account has run out, as the denial of access to the service may be caused by their absence.
Antenna problems
To process the incoming signal, many TVs are equipped with a special receiver. In most cases, the TV does not show well from a common antenna due to weather conditions. They can be rain or heavy cloud cover. This problem can be solved by replacing the antenna with a better and more sensitive one.
There are still cases when interference is caused by the deformation of the antenna. This can happen due to strong winds, hail or in the event of heavy snowfall. Snow lying on the rails can bend them with their weight and disable them.
In the absence of mechanical damage, a strong wind could turn the antenna, which caused a decrease in the signal reception level. This happens due to incorrect installation. If we talk about a satellite dish, then from time to time it requires adjustment of the settings, since the satellite may slightly deviate from the original trajectory.
Weak signal reception
As mentioned above, thisrefers more to the owners of country houses. Often in the country or in the village, the TV shows badly in comparison with the city. The reason is that due to the influence of the atmosphere, the signal does not reach the receiver with sufficient strength, since transmitters are usually located in large settlements. As a solution, you can replace the receiver with a more sensitive one. However, this option is not suitable for indoor antennas, as they do not have enough power.
Urban residents may have similar problems due to illegal interference with the design of the antenna and switching. Any changes must be carried out by professionals and after obtaining special permission. Otherwise, dismantling can be achieved through the courts.
Switching problems
Often the reason that the TV does not show well is poor contact between the antenna connector and the corresponding TV jack. Periodic deterioration of the connection will create distortions in the picture and sound. To begin with, it is worth examining the connector itself and the input of the device. In case of damage to one of them, it is necessary to replace the failed part. If both of them are in order, then you need to reconnect them, making sure that the contact is tight. If a splitter is present, it is necessary to inspect the contacts on it. When all the contact points are checked and everything is in order, and the TV does not show well from the antenna, what should I do?
If these steps fail, inspect the antenna cable for damage. It is undesirable to pinch it with pieces of furniture or bend it at a strong angle, as this can damage the wire from the inside, and it will be more difficult to diagnose the problem. If your antenna cable runs outside your home, make sure it is securely attached to the wall when you first install or replace it, as wind vibrations can cause internal damage or a complete break.
Error in settings
In order to tune in to a specific channel, the receiver must catch the frequency corresponding to it. This problem is especially common in analogue broadcasting. If there is incorrect information about the channel, the TV receiver cannot find the corresponding signal. This can be caused by self-configuration attempts or some kind of failure that caused the device to be reset to factory settings.
If such a problem occurs, most likely, the TV does not show most of the channels, and the rest are mixed up and are not on their "buttons". In this case, the device must be configured by a service center specialist, since for an ordinary user such a process is very complicated. Also, if television services are provided to you by a provider, you need to call technical support and call the master at home. Even in cases where the TV does not show well, the problem may arise due to an unnecessary signal amplifier in such a situation, which must be turned on only in case of uncertain reception.
TV breakdown
If the image on the screen has deteriorated sharply and switching channels does not change the situation in any way, then most likely the receiver or converter has failed. These parts are not repairable and will need to be replaced to resolve the issue. If the warranty period of the device is valid, such repairs should be carried out free of charge.
It is worth noting that such cases are found mainly in fairly old TVs. And, of course, most of these problems are solvable. So if the TV does not show well, what to do, you now know.
