What to do if there is no signal on the TV

Today, it is difficult to imagine life without television broadcasting. No signal - a fairly common problem, which sooner or later most TV owners face. Reasons, for which this fault may occur may be several. Them, first of all, include:

hardware problems;
preventive work;
external factors.

Hardware problems

The most common reasons, for which there is no stable signal on your TV, from this category, usually, is:

connecting cable defect;
satellite dish or antenna malfunction;
satellite converter failure.

The problem with the connecting cable can be an obvious answer to the question, why there is no signal on the TV. If the antenna or satellite dish has a poor connection to the device due to cable damage, such a situation is quite justified. Check the plugs and the wire itself for defects. By the way, it is the quality of the wire that also affects the transmitted signal, so it will not be superfluous to know, how to choose the right cable.

If you use a satellite dish to receive a TV signal, you need to make sure, that she is in the right position (a little below we will give advice, How to do it).If the satellite receiver is covered with a layer of dust, ice or dirt, not wonderful, that it doesn't work. In this case, the surface should be carefully cleaned.

Failure of the satellite converter is a fairly common cause, on which there is no signal from the satellite on the TV. The converter acts as a regulator, which reduces the frequency of the signal from the satellite to reduce losses during signal transmission. To solve the problem, replace the faulty converter with a new one.

Importantly: if you are unsure, what do you know, how to do such manipulations with a satellite dish - entrust this task to an experienced master. Otherwise, you risk causing irreparable damage to the device.

Preventive work

If your TV says "no signal" in extremely rare cases - maybe, your operator performs preventive work to eliminate delays and other problems in the speech of the TV signal. The only way out is to wait, until the preventive work comes to an end. It is quite easy to distinguish one reason for the absence of a signal from another:

take the remote control from the receiver;
enter the system menu;
check, whether there is an inscription "no signal" in the menu of the receiver.

If the device starts writing about the lack of signal in its system menu - then, the problem lies in the satellite of your operator. In some cases, the prefix may "hang" (for cable TV subscribers). Try rebooting the device: disconnect from the mains, and after 30 sec turn on again. Perhaps, the problem will disappear. The same steps can be performed in the absence of a signal on Tricolor TV.

In any case, it is not superfluous to contact your digital TV provider, to find out, what to do in a situation, prevailing.

External factors

What shall I do, if there is no signal on your TV with some external factors? Obstructed obstacles in the form of tree branches and other foreign objects can interfere with the passage of the TV signal. If you have the opportunity to fix the problem - you're in luck. If not, then the only solution may be to reinstall the satellite dish elsewhere. For tips on setting up a satellite dish, read the article on connecting to a satellite TV.

How to set up a satellite dish yourself

To make the settings of the satellite dish with your own hands, necessary:

go to the operator's website and find the angle calculator;
enter the coordinates of the satellite and find out its location;
aim the antenna at the satellite, using data, received earlier.

You can determine your current location with a regular smartphone. Usually, their accuracy is enough to choose the optimal direction of the plate.

If you often have problems with lack of signal, then you need information on how to improve your TV signal. Perhaps, you need to select a new antenna. In any case, this problem is solved, as for old TVs, and for new ones.
