When your Samsung TV won’t turn on, start by trying to reset your Samsung TV. Disconnect the power cord from the outlet, then press and hold the TV power button for at least 10 seconds. Plug the TV back in after waiting a couple of minutes and press power on. There could be one of three options: standby light is red and flashing or not working or standby light is green. If you see blinks on Samsung TV’s, it usually indicates a bad power supply. If you see it not working, this is a power issue. If standby light is green, then it could be an issue in the panel.

One of the most frustrating things is when you get home at the end of a long day, go to turn on the TV and get no response. Although Samsung equipment, produced by the famous South Korean, has always been considered one of the most reliable, it can sometimes fail.

The first and the most important stage of repair work is to find out why the Samsung TV does not turn on and the diagnostic results will show the cause of the failure. Depending on the complexity of the malfunction, you need to fix it yourself or contact a specialist. Below is a list of things you can try to find the reason why your Samsung TV won’t turn on but first, let’s go into the causes.

What would cause my Samsung TV to not turn on? 

To determine why Samsung TV won’t turn on, you first need to inspect the device for external damage and only then proceed to the diagnosis of the hardware component. Here are a few reasons why this can happen:

1. Standby mode: When the red light stays on and the display turns off, the device continues to function. To start the TV, press the power button on the front panel of the device or the remote control.
2. You have broken remote control. First, you need to change the batteries, and also check all the keys. You can always download a special application on your smartphone – TV-remote so that you can switch channels and adjust the volume using the most ordinary phone.
3. Broken socket. If the indicator does not light up on the control panel, connect the TV to an alternate power source. After that, you can continue to use the device.
4. It is likely that the emergence of this failure is caused by the activation of AV, HDMI or wireless internet connection. As a result, an image from a mobile device or laptop is displayed on the screen. To resume watching terrestrial TV, simply turn off all devices and check all connected hdmi to vga converters.
5. Low signal strength. Due to a weak signal, only a black screen is visible on the TV screen, often due to adverse weather conditions: excessive precipitation, thunderstorms, etc. Do not rush to take any action, and it is likely that the broadcast will resume in a few hours.

To independently determine why the TV does not turn on, you do not need specialized equipment. Now let’s analyze the main breakdowns that users encounter most often.

A Step by step algorithm for turning your Samsung TV on again.

A lot of power issues can be the result of a hardware problem, and the best thing to do is to get a trained Service Technician to take a look at your TV if you are having trouble. There are a few things you can try at home first: First, you need to check in which mode the television equipment is now.

If it is in standby mode, it will display a red light indicator on the bottom left hand side of the TV’s main panel. To resume TV broadcasting, you need to exit the standby mode.

1. Press the “Power” button on your remote and check if the LED is turned off.
2. If it turns off, this means that the TV is connected properly to the power supply.
3. Test if the screen is functioning properly by lightly tapping your finger on the screen. If the screen blinks, it means that it’s working properly.
4. If the screen doesn’t blink or the LED doesn’t turn off it means that either there is an issue with your remote, the power supply or the screen is faulty. There is also a possibility that you are experiencing a black screen on the Samsung TV.

 

PLEASE NOTE: Experts strongly recommend not to leave the TV in standby mode for a long time as power supply circuits remain active and can cause a voltage drop in the network. The supply circuits will burn out. Of course, in the end, the TV device will not turn on. Thus, one of the solutions to fix why your Samsung TV won’t turn on, is to deactivate Standby mode.

 

Samsung TV won’t turn on and the standby light is red

In some situations, the indicator lights up green but then turns red again. This indicates that the central processor was formed and sent to other modules the incoming signal to turn on. The LED can constantly change color, but the TV never turns on. The cause of the fault is an inverter or a transistor. It is necessary to contact the service center so that the specialists change the faulty modules.

If the TV does not start after pressing the power button located on the panel, look to the standby indicator. If it is turned off when the button is pressed, this indicates the activation of the internal lock.

It is not necessary to exclude breakages of the button itself or the loop providing the connection.

If, when pressed, the button literally falls inside the panel and does not click, then it needs to be changed.

You absolutely cannot do it yourself, so you just need to visit a Support Center.

If you are able to turn the TV on this way, the problem may be with your remote. 

 

2. Check the TV remote

If your remove doesn’t work, you need to replace the batteries.

Then you should check the keys, perhaps some of them stick, work only after a few clicks.

In addition, the execution of commands for the backlighting of indicators, turning on the TV, etc. is being tested.

When the light comes on, indicating that it is working, but there are no signals from the main board, this may signal problems with the software.

Try to turn on the device with a remote control or by pressing a button located on the main panel.

Hardware failure of the motherboard is fixed by replacing the defective component.

If the voltage is a complete order, then the specialists will reset the user settings, and then install the updated software.

Samsung TV won’t turn on and the Red Light Flashes

If the TV does not turn on, and the indicator blinks, then the problem lies in the power supply. A constant red flashing light is a failure indicator, but you need to specify the problem, which is very difficult.

To determine the cause of the appearance of a flashing red light on the TV, a comprehensive diagnosis is carried out.

Using an oscilloscope, the power adapter is checked, and the efficiency of the converter located on the motherboard is also tested.

When the red light flashes it is usually due to voltage problems on your Samsung TV, hence why it won’t turn on. For example, a short circuit has occurred in the contact circuit. The quickest way to test is by disconnecting the power supply from the board main board, plug in the power supply board, after that if the power supply is good, you should see some lights in the screw holes and the problem is not there.

A professional engineer can only remove hardware breakdown of the Samsung TV. An ordinary user will be able to solve problems of external character

Independently disassembling a device is by no means the best idea, especially if you don’t know what you are doing.

Software failures Samsung Smart TV is also not always possible to eliminate on your own.
