Today, every average family cannot imagine their life without a TV. Despite the development of the Internet industry, television still occupies the first place in holding a family evening. But if the TV does not turn on, what to do in this situation? First of all, in this case, you should not panic. When the TV stopped responding to the start button, this does not mean that it is time to call a specialist.
First you need to inspect the equipment yourself. Most of the breakdowns of modern technical products can be corrected on their own, using the advice of professionals. Most often, such a breakdown is caused by banal user errors. If the TV cannot be started, the mode is probably incorrect, the wrong buttons were pressed by mistake, the power cable is damaged or disconnected. To determine why the screen does not turn on, you must first find out the type of this household appliance. After all, the appropriate approach will depend on this. To date, the following are considered popular:
- Plasma screen;
- LCD monitor (LCD);
- kinescope (older models).
The user does not need to disassemble his equipment and try to master the boards and systems. Therefore, the repair of any TV model will not have big differences. Recommendations for eliminating the causes when the TV does not turn on may also be suitable for repairing other household appliances.

If an LCD TV was recently bought, and does not turn on immediately, as soon as it was installed in the house, then there may have been connection errors. The possibility of factory failures is unlikely, as every reputable company tests its products well before being exported to the market. If a similar situation arose and the device does not turn on, there may be errors in the connection, a breakdown of the remote control, or improper control of the equipment.
What to do in such cases? It is required to read the instruction manual of the purchase again and start again. For example, why the equipment may not respond because the main power button is in the off position. When the signal LED is lit, does not blink, the TV is powered properly. But if the light does not respond to your actions, the start button for the equipment or the power cable may be faulty. You should carefully inspect the power outlet and the cord itself. The socket should be checked with a special tester screwdriver, in which an LED is built in. If it flashes frequently when the tools are moved, there is a possibility of contact divergence. There are times when the LED on the voltage indicator flashes due to its own malfunction, such breakdowns do not deserve attention. If such areas have been reliably checked, and the equipment does not respond, the breakdown must be looked for in other places.
Wrong mode selection
If the indicator lights up properly, but the device does not work, the cause of the power supply should be excluded. Now you need to deal with the modes of operation of the TV. Most of the new models of modern production are equipped with several modes of operation:
- to watch DVD;
- Game Mode.
And this is not the whole list. Each of them requires detailed study for proper use. If the power button does not help, it is likely that sleep mode is activated. It is not difficult to find out — the monitor goes out in this position, but the signal LED glows red. After that, you should familiarize yourself with other modes of technology. For certain models, it is common to have a button that allows you to identify the current mode. When the game mode or DVD player has been set, the monitor will turn off, the indicator will be on in such cases. You should also inspect each player or game console connection jack. If it was not possible to connect a set-top box or player, but the mode has already been selected, the monitor will turn off.
The reason why the TV stopped turning on may be due to a malfunction of the control panel. To check this, you should press the start button — when the LED blinks, this indicates the correct operation of the remote control. But when the LED does not blink or does not light up at all, you should inspect the remote control. Sometimes you just need to change the batteries and the problem is solved. When the same remote control is available, it is recommended to try to turn on the equipment using it. If again there are no changes even when using another remote control, you should try to start the technique from the button on the case itself.
Often, when a breakdown occurs, the built-in speakers reproduce typical sounds — the TV clicks, cracks, etc. When the column clicks at the moment the remote control is pressed, this indicates that the remote control is working normally, the cause must be looked for further. Some modern TVs have a characteristic sound signal that reacts to the lack of connection with another device or the wrong mode.
When the equipment constantly clicks, but does not turn on, you should find out the peculiarity of these signals. A single signal while turning on the TV cannot be regarded as a breakdown. Depending on the manufacturer of the device, this beep can be more or less loud.
When TV cabinet parts are made of cheap plastic materials, they can also produce typical clicking sounds. Causes this heating, then cooling of these parts. Such phenomena should not be considered a breakdown either, although this can be pretty annoying.
When the TV failed to turn on, but it clicks, the problem is probably in the power supply, which stops the start of the equipment. This can be determined as follows, when a clicking sound occurs after pressing the start button and disappears after the TV is turned off, the probability of failure of the power supply or other internal part is very high.
