How to identify the different causes for why does digital tv keep losing signal? And solve how to intervene in the correct way to solve it. Even nowadays, with the most modern Smart TVs on the market, it could happen to run into annoying problems of disturbed TV signal. With the consequence of not being able to watch the channels of our interest on digital terrestrial. This guide was created precisely to put an end to the question, where possible, by identifying the different situations in which one might encounter.
Why does digital tv keep losing signal?
The main causes that cause a digital terrestrial signal will be explore disturbed and what to do in practice. What is useful to know is that these are easily resolved critical issues, which fortunately do not require the intervention of a technician and can be stemmed in the first person within the comfortable home.
Digital tv interference on some channels: what to do?
To start exploring the topic and understand what to do in the event of a digital tv interference on some channels. It is important to understand what are the elements we are going to handle. This is in the specific case of the traditional components of a TV system. In fact, it is not only the antenna that influences the operation and reception quality of the television signal on digital terrestrial channels: the cables that connect to a signal amplifier or switchboard start from here., generally located in the attic of our home or in a dedicated control unit inside the building. In turn, all the branches that must wind their way to the individual sockets start from the switchboard. In condominiums, it is common to find them on the landing of each floor, while in individual apartments, boxes are installed for the internal distribution of the sockets.
Now that we have learned the basics, the first thing to do if the digital terrestrial TV signal is weak or absent is to understand if the antenna is shared with other homes, as happens in a classic condominium. In such cases, it is advisable to ask the neighbors whether the situation is also happening to them or not. If so, the cause of the fault must likely be found in a failure or altered operation of one of the common parts of the system, i.e., the antenna above, cables and main switchboard.

Disturbed TV signal: the most frequent causes
Let’s move on to the hypothetical scenario in which disturbed TV signal involves all the condominiums present in the same housing structure. The main causes, in this case, can be two. The reference goes to the condominium switchboard not powered or to a technical fault in the condominium control unit. In the first case, usually recognizable when the digital terrestrial is seen in jerks, the verification to be carried out is rather quick: if the light of the condominium stairs does not work, the problem may be precisely that, considering that it is not uncommon for the two plants to share the same differential.
Usually, you can find the switchboard of your building in the meter room, and it must be set to ON to receive the television signal again. If, on the other hand, the switchboard is powered correctly, but the absence of the television signal continues, it is very likely that the central unit of the building needs to be repaired. The only thing to do is to contact both a specialized technician and the building administrator.
It could also happen that the signal is absent only in some residential areas. In this case it is advisable to check if someone has carried out a renovation of some kind or any work that may have affected the system. It is different than if the absence of a signal occurs only inside one’s own apartment since the cause of the fault will necessarily be linked to an “individual” problem.
The first thing to do in a case like this is the most obvious one: to check that the problem is present on all the televisions in the apartment if there is more than one. If it’s just a TV that’s causing problems, then try replacing both the power plug and antenna cable before calling an expert. If the disturbing TV signal affects all the appliances in the house, the fault should be attributable to the TV signal distribution lines.
Especially due to wear due to time passing or to system construction work carried out too roughly. Finally, if the problem is related to the lack of signal only on certain channels, the reason is to be found in the absence of those channels from the reception area or from the incorrect tuning of the frequencies.
