The TV does not turn on the LED is red

Answer

After turning on the TV using the button or joystick on the TV, the TV screen remains black, but the LED indicator is on. If the front light (standby) indicator is lit, the TV is still in standby mode. Turn the TV on with the standby button on the remote.

Note: Many of the 2015 and 2016 TV models have the feature of a “pulsing” LED (standby mode) when the TV is turned on. This is intentional TV behavior to show that the TV is “booting up” (starting up). When the LED light stops pulsing, the TV is fully functional and can be operated using the TV remote.

If the TV fails to turn on, go to step 2.

The most common cause

The most common reason for the TV set not to work is the disconnection of the “Network” button. It is available in all modern models. This toggle switch is placed at the bottom, at the side or at the back of the device. If you move it to the “off” position.”The device will not respond to signals from the remote control. Someone in the household, such as a child, might have pressed the switch. If the TV still doesn’t work after you checked it, you need to keep looking for possible causes.

Sometimes the TV takes a very long time to boot up and no picture appears. This indicates a software failure. It is possible to reflash the device on your own, if some information is still present on the screen and you are able to enter the system settings. When the monitor doesn’t respond to the signals from the remote control, it’s necessary to apply to the service center.

Problems with TVs of different brands

Now let’s look at breakdowns common to equipment from popular manufacturers.

Samsung TVs

First it is necessary to make sure that there are no problems related to power supply. There are several options:

  • The power button located on the front of the TV doesn’t work;
  • Faulty remote control or dead batteries;
  • The power cable is damaged;
  • The socket does not work;
  • problems with electricity.

Practice shows that owners of Samsung TVs of the following models face similar problems:

Problems with switching are observed even if there is no visual damage. Complete absence of indication. an indicator of power adapter burnout. Probably the socket is out of order or the light is banal. To change the power supply yourself you need to disassemble the TV and carefully disconnect the broken module. You need to use professional equipment and have the appropriate skills. If the equipment is still under warranty, contact an authorized service center.

Phillips TV: Where to look for the problem

The owners of TVs of this brand write in their reviews that the equipment quite often arbitrarily goes to sleep. Modern models support functions that contribute to the automatic switching of appliances to “sleep”, which sometimes causes problems.

Try to turn TV on with remote control. No reaction? Then unplug the power cord from the outlet and wait a few minutes, then plug it back in. Perhaps the problem is not due to the sleep mode, but due to a breakdown of the hardware components. In this case it is better to trust the professionals.

Black screen indicates a breakage of the backlight, processor or banal wrong connection of the antenna cable. Check the cable for damage.

In some cases, the screen lights up, but almost immediately the image disappears. This is an indicator of inverter or matrix malfunction. Such an expensive type of repair is better to entrust to professionals.

If the TV turns on too long, the problem could be in the nodes of the power supply. Possibly not enough power is being supplied.

LG brand TVs

A popular brand that many users associate with the best ratio of affordability to a small price. Problems with the display most often occur in the following models:

The accompanying documentation describes the indication codes. Correctly interpreting the flickering LED, users will be able to restore the equipment on their own.

Indicator lamp is on all the time

If the LED lights up, it means that the control unit is receiving power. If the TV does not react to signals from the remote control, the first thing you need to do is try to turn it on directly with the buttons. The problem might be the remote control malfunction and not the TV itself. If this is indeed the case, you need to take the following actions:

  • Check if the batteries and contacts are working properly and check for oxidation.
  • Check the integrity of the transmitter and the lack of sticking buttons remote.
  • If possible, disassemble and clean the inside of the remote control from dust.
  • If remote control was flooded with liquid and does not work, return it for repair or buy a new one (preferably the original one as it will last longer).

If the TV could not be started from the panel, there are two possible scenarios.

Protection has tripped

The TV may try to start, but after a few seconds the screen goes blank, or does not turn on at all. The main reason for such malfunctions in most cases are interruptions with the electricity supply in the home network. This can be a voltage drop or switching on and off the power at the moment of finding the TV in “sleep mode.

The most effective way to solve the problem is to completely disconnect the device from the network for a while, and not with the remote control, but to remove the power cord from the outlet. This will be enough to restore performance if the TV does not turn on after a power outage. If the problem with voltage is constant, you’ll have to use a stabilizer, an uninterruptible power supply, or at least a surge protector. And when you leave home, it’s better to turn off the TV completely.

Processor or control malfunction

You can see from the schematic that LEDs are controlled by the Stand By wire and the Q211 transistor. If a short circuit occurs, the TV stops turning on.

In this case you will need to call a service technician. Attempting to do complex repairs on your own can completely disable the TV.

If the TV turns on and the channels are switched on, the remote control most likely has lost or run out of batteries. Also in the remote control may break the quartz resonator after a fall.
