Antenna and cable problems

If the TV worked all the time normally, and then the picture was badly spoiled, then a reasonable question arises: why did this happen? To answer it you need:

  • check all connections;
  • check the condition of the cable; it may be pinched or interrupted;
  • make sure that the settings are not lost.

If the TV catches on the antenna, it is necessary to see if some trouble has happened to it. After a strong wind, hail or snowfall, the antenna can change position, bend, break, a heavy object can fall on it. If there is an individual antenna, check the reduction cable. It must be viewed visually and ringed with an ohmmeter.

.

The satellite dish can also change its position under wind pressure, and in fact it is very important for it to be oriented in a certain direction with great accuracy. When the position changes, the channels start to show poorly or disappear altogether. To properly set up a satellite dish, one person should twist it, and the second monitor the signal level.

.

It happens that the reason for a bad TV display is the failure of the receiver or converter. See if the device's light is on, if an access card is inserted for the coded channel. If the devices are under warranty, then they must be returned for repair or replacement.

If you have an antenna in common with neighbors, the neighbor shows well, but you are not, then first check the cable. From cable wiring in the shield parallel to the home cable, throw a piece of another cable and connect it to your TV, a mini apartment wiring. If the TV began to show better, then the case is in the wiring, otherwise look for the cause in the TV or in the noise generated by household electrical appliances.

Trouble with cable TV

When you connect a cable television, when the signal is propagated with a cable, the reasons for a poor display may be the improper tuning of the channels. You must reconfigure or contact your service provider. If the image is clear, and the sound is wheezing, then in the settings you need to set the sound standard DK.

After you are convinced that everything is in order with the setting, and the service provider has confirmed the good quality of the signal, it is necessary to check the condition of the cable. Maybe it's too old, frayed in some place and it must be changed to a modern type.

There is a statistics of the reasons for which cable television is poorly displayed, and which answers very well the question of why communication problems occur. Here's a big part of them.

  • The TV plug is not fully inserted into the socket.
  • The integrity of the cable is broken.
  • Wrong connection in wiring to TVs or apartments.
  • Use of low quality dividers.

According to the connection scheme, the difference between a cable TV and an antenna is that when a cable is connected to a small area of ​​several houses, one transmitting node is installed. If for some reason the power supply of the node is interrupted, then all users who are connected to it will not receive a signal. In this case, it is necessary to eliminate the main problem by providing a power supply to the node. These issues are covered by utilities, and nothing depends on users.
