Many experts predicted the crowding out 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 has not been possible to solve the problem with the image on the TV, and many are wondering why and what to do if shows bad TV?
Factors affecting the image
- the TV set up was done incorrectly;
- 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 number 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 splash screen 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 be absent in the event of damage from your cameraman. 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 with 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. During bad weather conditions, such as a blizzard, rainstorm and nebula, these receivers begin to pick up the signal poorly and you may experience problems with sound and image. In order to neutralize these factors, you just need to install the antenna more powerful.
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 other direction. This can be due to poor installation or the use of inappropriate fixing devices.
Interference during signal reception
Most often, this problem is faced by residents of summer cottages, rather than city apartments. Many people complain that their TV shows poorly.And this happens due to the property of the radio signal to scatter in space, since urban transmitters are most often located in large cities, and the signal does not cover long distances poorly. To solve this problem, it is necessary to replace the receiver with a more powerful one or raise 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 must be produced only with the approval of the supervisory authorities. In the absence of this permission, you can request the dismantling of this equipment by contacting the courts.
Faulty wire or attachment
There are cases when the TV shows poorly due to the lack of tight contact between the wire and the inlet of the receiver installed in the device. Due to gusts of wind or other reasons, the contact may periodically move away, after which the image starts to junk or gray-black ripples appear 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 need to 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 wire it with large bending angles, this may result in an internal cable break that you cannot visually notice. If the cable is not in the entrance, but outside, then it must be rigidly fixed to the facade of the building, because during bad weather it can begin to dangle and catch on 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 TV broadcasting services from a private operator, you can contact the support service 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 began to show poorly the image unexpectedly for you, and during the process of switching channels, no visible changes occur. This problem is especially acute on old technology, but in some cases, models of new TVs are susceptible to it, having stopped normally displaying the picture 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. You are unlikely to succeed in subordinating these parts yourself, so the best option for you would be to replace the adhesive part with a new one. 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 everything replaced for free.
