The widespread development of technology allows you to get the latest news from any access point. However, people's lives are still unthinkable without a TV. A TV receiver is an integral element in any home, almost a member of the family. Therefore, as soon as problems arise, a person is puzzled by the search for a productive solution.
If the TV spontaneously turns off and on, the breakdown should not be left to chance, because in addition to unpleasant breaks while watching, the TV can turn on and work in the absence of the owner - the electricity bill will increase accordingly. But before eliminating it, you need to understand the reason for the appearance.
Why the TV itself turns on and off
The TV turns on by itself. The malfunction is often inherent in modern models due to software, including televisions from trusted manufacturers. The malfunction is completely uncharacteristic of kinescope TV receivers, but is sometimes associated with them. The problem has a lot of reasons, but not all of them are breakdowns. Often, you should understand before urgently changing the TV or rushing to the service center.
IMPORTANT!Trying to find the cause yourself, you should not forget about safety. Before diagnosing, be sure to disconnect the TV from the power supply.
Can the TV turn on by itself or turn off? The main reasons not related to equipment breakdown:
- Incorrect device function setting. Automatic shutdown due to the lack of a reception signal, as well as actions by the user. In other words, the TV believes that there is no need for its work (which is very convenient if the owner likes to fall asleep when watching movies). But incorrect settings can lead to a visible malfunction.
- Installing a program that sets the time for automatic on and off.
Spontaneous inclusion of the TV - it is easy to solve the problem, you just need to go to the functional menu and turn off unnecessary options.
REFERENCE! Before you worry, you should also check for voltage on the network. Perhaps it is unstable, because the technique reacts like that.
Does the TV turn off and on by itself? The next thing to check is the contact density of the plug in the outlet. A loose-fitting plug will constantly move away from contact, especially if there are pets or a person moving around the apartment. Animals can pull out the wire, and the vibrations created by the movement can share a loose contact.
Dust accumulated in it
Does the TV turn off by itself? The next problem is accumulated dust. People often clean laptops, purge computers, and even wash the refrigerator to ensure proper care. However, television equipment always disappears from sight. Meanwhile, dust can also accumulate inside the TV - rarely, but there is such an opportunity.
REFERENCE! Typically, TVs are protected by a dense housing, which has lattice openings for timely ventilation. They are also blocked from dust (superimposed on each other, air penetrates - dust less often), but such an opportunity is still present.
Dust is not an electrical conductor, but sometimes its amount is enough to short circuit on the board. It is enough to use a vacuum cleaner to clean - you need to remove the back cover and go over the entire surface, details.
There are problems with the power circuit
Why does the TV turn on by itself? The next problem may be related to the power supply, more serious diagnostics will already be required here to check the operability of the entire board. The first step is to check the standby indicator. If it blinks, then the malfunction really arose with the power board. The TV needs to be taken to the service or to replace the failed parts yourself.
IMPORTANT! Be sure to check the socket, wire and plug for damage.
Voltage drops present
Another reason for the spontaneous operation of the TV. The reason for this is prolonged use, as a result of which mini-cracks appear on the board. Humidity, unstable voltage, high temperatures - all this leads to breakdown of the connections and bloating of capacitors.
The TV itself turns on and off: what to do? The TV needs to be taken to the service or, as in the previous case, try to fix it yourself. Be sure to follow the safety precautions when checking the board for damage.
These are the reasons for the spontaneous operation of the TV for no apparent reason. Some can be eliminated on their own, armed with a soldering iron, others are subject only to a specialist. In any case, such a malfunction is not a reason to buy a new TV receiver.
