TV does not turn on

The TV sometimes stops functioning as it should, while the indicator either constantly lights up or flashes completely unevenly. If this is the case, it's time to start looking for the causes of the malfunctions, why the TV does not turn on.

A television receiver may fail for a number of reasons. Moreover, they mainly do not depend on the popularity of the brand, the model of a particular device and other external reasons. As for the TV device, it can be:

  • CRT;
  • liquid crystal;
  • plasma;
  • LED light.

However, the causes of damage to the device are not associated with these indicators. They can be exactly the same for very ancient models, as well as for ultramodern ultralight and ultrathin options. Among them, there are breakdowns of the power buttons, an incorrectly selected operating mode, malfunctions of the control panel, improper connection of plugs. in the first case, the receiver simply does not turn off, in the second there is no image on the screen. If there are problems with the remote control, the device does not respond to pressing buttons on this device, or the battery that supplies the remote control has run out of life.

Indicator flashes

This state of affairs provides a lot of information. Firstly, electricity is supplied to power the TV. Secondly, the indicator, one way or another, detects a breakdown, although it flashes red, which greatly helps in the search. It may well be that the problem is the malfunction of the remote control. It is necessary to find out why:

  • check the batteries, if the power sources are exhausted, if the connection is made correctly;
  • will study the operability of a device that tends to fail often;
  • make sure that all components are working properly.

In the event that attempts are made to correct the situation, but the light remains active, then the error should be sought using the instructions for this model of TV. Usually in each such booklet there is a section devoted to possible malfunctions and methods for their elimination. You should definitely take advantage of this.

The indicator lamp sometimes does not work evenly when the TV is used to perform the functions of a computer monitor.

REFERENCE! The same can happen if the settings of the operating mode are selected incorrectly. In this case, for the TV to function properly, select the AV mode, not the PC mode.

On some models of TVs, the indicator may not blink randomly, but in a certain mode. For such receivers, manufacturers have provided self-diagnostic functions, certain results which a blinking light demonstrates. The signals are intended for service technicians who in this way quickly and easily detect the cause of a breakdown.

LED is steady

The indicator lights up without a wink, but the TV does not work? In this case, we can also conclude that the power is supplied to the receiver, is supplied normally, and the cause of the breakdown is not in it. You should try to turn on the TV using only the remote control. In this case, it will be possible to check the serviceability of the remote control.

The device may have various problems, one of which is sticky buttons. For this reason, turning the device on or off does not work. Accordingly, the remote control must be cleaned, or purchase a new one. And if the batteries are dead, they should be replaced. If necessary, install the batteries correctly.

IMPORTANT! If the indicator light is on, but the TV does not work, it is possible that the breakdown is in the motherboard.

A software malfunction is also possible. Reliable and reliable diagnostics can only be carried out at a service center by specialists who have the necessary experience and have access to the appropriate specialized equipment.

In which TVs do these problems occur

With general similarity, all modern TV models can differ in many nuances. These are technical solutions of manufacturers that equip receivers with certain capabilities, or simply there are certain imperfections that affect the quality of the device.

Usually, all the problems and their solutions are indicated in the instructions for the TV. This document is supplied with the receiver and other components. If the brochure is lost, the instructions are easy to find on the official website of the manufacturer or on the Internet.

The TVs of the South Korean manufacturer Samsung come across a wide variety of shortcomings. Therefore, the search for the causes of device malfunctions should begin with power. It is possible that the power button on the TV does not work, there is a malfunction in the remote control, including inoperative batteries. Among the most common problems are a breakthrough of the network cable, a malfunction in the outlet, broken extension cords.

Models may be problematic:

  • le40r81b;
  • le32r81b;
  • le23r51b;
  • le40s62b;
  • le20s52bp.

On Philips televisions, the active mode may not be the cause of the problem. These models have a feature called “sleep mode”, that is, the TV is connected, but without an active image. It is treated by changing the settings. In general, just press the appropriate button on the remote control.

Damage to capacitors, power supply, microchips, and other parts is not ruled out. You can fix the problem only in stationary conditions of a certified service center. User actions should be limited to turning the receiver on and off with the remote control and the panel.

South Korean manufacturer LG produces models:

  1. 42pa4510;
  2. ld33b;
  3. 42ld650;
  4. 42la621v.

The developers of the receivers have provided a flashing coding system. Each variety indicates a particular problem in the functioning of the device.

Overheating can be a common cause of difficulties turning on the TV. In this case, the device just needs to be turned off for a while and then turned on again.

How to get rid of a problem

It should be noted several basic approaches to solving the problem.

  1. Check for electrical current in the household network. Make sure that power is supplied correctly. If not, take steps to rectify the situation.
  2. Check the settings, make sure that “sleep mode” is not turned on.
  3. Check the operation of the remote control.

In all other cases, contact a service center.

Modern TVs of all types are very complex devices, the technology of their manufacture involve the use of components and functional units that cannot be repaired without the use of special equipment. Employees of service centers that serve customers in a particular area are specially trained to work with certain models. Only they are able to diagnose complex problems and find solutions.

Attempts to independently solve problems with the TV are fraught with damage to a cheap product. Often the consequences of such actions cannot be eliminated.
