Due to the planned disconnection of apartments from analog TV broadcasting, the majority of the population switches to digital television, because it is characterized not only by high-quality images, but also by uninterrupted broadcasting. However, despite the obvious advantages of the technology, problems are possible here. Most often, they consist in the fact that digital television channels stop working. Let’s see why digital television does not show today.


Bad weather can be another reason for a weak digital TV signal. Strong gusts of wind, thunderstorms, rain and snow can affect signal reception. In this case, there may be a deterioration in the quality of the image and sound, and the picture may be displayed in the form of “squares / pixels”. The complete absence of a signal is also possible. In this case, check the signal level on your equipment. If the indicator is low, you should increase it to the maximum. It turns out that weather conditions will not be able to affect the loss of digital channels, but only some signal deterioration.

Antenna malfunction

A common reason for the lack of broadcasting is the direction of the antenna towards the transmitting tower.

An antenna that is outdoors is most susceptible to damage. From frequent ingress of moisture, strong winds, elements can be damaged and there is no digital TV signal. Follow these steps to identify the problem:

  • Check for voltage in the power supply.
  • View cable connections to devices, plug.

If the equipment viewed does not help identify the cause, connect another antenna and test. If the new antenna also does not work, then the reason is different.

Faulty cable and connections

A faulty cable is a common problem. Since part of the cable is located on the street. during long-term operation, the winding is destroyed and erased, and this leads to cracks. It is important to review all cable connections for integrity. In case of damage, the cable will need to be replaced.

No signal what to do

Before proceeding to fix the problem, it is worth identifying what exactly it is. The reasons are divided into the following types:

You will need to go to the broadcaster’s website and familiarize yourself with the schedule of preventive and repair work.

Stop broadcast

Preventive maintenance is a possible problem with the broadcast termination. To clarify, go to the broadcasting site of your region and view the information. To carry out test work, the second multiplex is turned off and the necessary information is collected. Broadcasting stops completely soon after. Today, in most regions, broadcasting is carried out using only one multiplex package. After disconnecting analog television, the ability to connect the second package will increase. If such preventive work is carried out, the TV and radio channels are temporarily disabled.

Poor signal reception conditions

Incorrect antenna placement can be a common problem with poor or no signal. It must be correctly installed and directed towards the direction of the tower. One of the reasons for poor signal reception can be bad weather conditions, as well as maintenance and repair work. It is also possible to break off the contact at the connections and cable connections. In this case, check all plugs.
