Many experts predicted the displacement of television programs and television in general, by the Internet, but this did not happen. With the development of technology, even to this day, it was not possible to solve the problem with the image on the TV, and many are wondering why and what to do if a shows bad TV?
Factors Affecting Image
- TV setup did not work properly;
- inconsistency of the technical characteristics of the device with the transmitted signal range;
- adverse weather conditions, such as snow, rain or fog;
- clutter of the communication channel with other sources.

Carrying out preventive work on the TV channel
Sometimes there are cases when the signal on the channel disappears for a certain time (most often for a period of several hours) in order to perform a series of technical manipulations to maintain the equipment. In the case when other channels are functioning normally, you need to wait for a while and the broadcast will resume itself. In some cases, during maintenance, a special screensaver may be displayed on the screen, which serves to signal that these works are being carried out.
It is worth noting that the image may not be available if there is a breakdown on the part of your teleoperator. In order to make sure that there is no signal, you need to contact the neighbors connected to the same operator. In the event that the problem for you and your neighbor is the same and does not go away for a long amount of time, you need to contact the operator by phone, or personally pay a visit to the office in order to check the status of your personal account or find out about possible repairs on the line.
Possible antenna problems
Most people in our country use fairly old radio receivers. These receivers during bad weather conditions such as a blizzard, rain and nebula begin to catch the signal poorly and you may have problems with sound and image. In order to level these factors, you just need to install the antenna in a more powerful way.
In addition to the above factors, a damaged antenna can also cause picture problems. It could be caused by strong winds or hail. The danger is also caused by the accumulation of snow, which could remain on the surface of the device and could not withstand its weight deform.
In the absence of visible damage, the antenna could change its position in space and turn in the opposite direction. This can be due to poor installation or the use of improper fixing devices.
Signal interference
Most often, this problem is faced by residents of summer cottages than urban apartments. Many people complain that their TV shows poorly. And this happens because of the ability of the radio signal to disperse in space, since urban transmitters are most often located in large cities, and the signal does not cover long distances well. To solve this problem, it is necessary to replace the receiver with a more powerful one or raise it antenna if possible by a couple of meters. It is worth abandoning antennas that are installed directly on the TV case, since they simply cannot provide the required signal.
Residents of high-rise buildings are faced with this trouble in the event of illegal interference in the telecommunications system. Often, the installation of new equipment leads to cluttering of the air, and the signal simply does not reach. Installation of all antennas and satellite dishes should only be made in consultation with the supervisory authorities. In the absence of this permission, you can request the dismantling of this equipment by contacting the courts.
Wire or mount failure
We can distinguish cases when the TV shows poorly due to the lack of a tight contact between the wire and the receiver inlet installed in the device. Due to gusts of wind or other reasons, the contact may periodically leave, after which the image starts to junk or a gray-black ripple appears on the screen. In order to eliminate this problem, it is necessary to disconnect the wire from the connector and check its integrity for the presence of oxidation, if the latter is found, clean it, and then return it to its place. If you have several devices installed in your room, it is necessary to inspect the adapter, since it is often installed incorrectly and could move away over time.
After you have made all the fastening checks, you must examine the cable itself for visible damage. Sometimes pets destroy the whole structure of the cable with their teeth and claws. It is strictly forbidden to hang any objects on the cable or to conduct its wiring with large bending angles, this can lead to an internal break in the cable, which you cannot notice visually. If the cable is not in the staircase, but outside, then it must be firmly fixed on the facade of the building, because during bad weather it can begin to hang out and cling to something, subsequently break, especially if it is of considerable length.
Incorrect device settings
This problem manifests itself in the absence of most TV channels and a spontaneous change in the positions of channels on your device. In this case, only a specialist should configure the device, since this process is quite time consuming and requires special knowledge. If you receive broadcasting services from a private operator, you can contact the support team and they will send a person to you.
In rare cases, interference can occur when the signal is excessive.
Hardware malfunction of the TV
It is worth focusing your attention on this point if your device has become poorly displaying images unexpectedly for you, and during the process of switching channels there are no visible changes. This problem is especially acute on old technology, but in some cases the models of new TVs are also subject to it, having stopped displaying the picture normally and outputting sound after a short time of operation.Most often, this problem is associated with a failed converter, which is necessary to convert the signal to low frequency. Less commonly, it is the receiver, which is responsible for receiving. It is unlikely that you will succeed in subordinating these parts yourself, so replacing the part with a new one is the best option for you. If the equipment is under warranty, you can contact the service center, which will diagnose and find out the cause of the breakdown. If the marriage is a factory one, you will most likely have it replaced for free.
