Extraneous sounds when the indicator is off and the TV does not turn on

Some devices, in addition to light indicators, are equipped with sound sensors. They are an indicator of possible malfunctions. These sounds have several meanings. The normal ones are:

  • after pressing the power button on the remote control, a single click is heard;
  • sometimes a small noise is heard due to the heating of the plastic parts located on the device body.

When the instrument is at factory settings, it is possible that characteristic signals appear indicating a problem. To decode the signal, you must carefully study the instructions. If a click is heard during power-on, and the TV first works, and then the image disappears, you can make an assumption about the damage to the microcircuit. A burnt-out part, after opening the lid, immediately catches the eye.

Indicator flashes

There are times when there are no network faults, the indicator light is on, but not constantly, it blinks randomly. One of the reasons for such a problem is a malfunction of the remote control. It is necessary to check its work, visually inspect, to determine:

  • mechanical damage to the case;
  • the state of the buttons (defects are not allowed);
  • the batteries are working, they may have run out, they need to be replaced.

If after checking the operation of the remote control the problem persists, you can try to turn on the receiver using the control panel located under the TV screen. If the connection fails, it means that the operating mode was configured incorrectly, or it has failed. The TV has various playback modes:

does, turn, light
  • standard;
  • sleeping;

  • the device is not connected to the mains;
  • damage to electrical wiring;

  • the power supply does not work, replacement is required;
  • the operating mode is incorrectly adjusted;
  • other technical problems (the microcircuit “flew”), without the help of a specialist repair is impossible.

The operation of the indicator will help determine the source of the problem, choose the right repair method.

The light is on continuously

If the lamp is lit with a bright continuous light, then the correct connection to the mains has been made. The problem is related to the operation of the remote control. If it does not have mechanical damage, you can try to push harder on the buttons, especially when they sink. If the problem is solved, it is better to replace the remote control in order to ensure the normal operation of the device.
