Samsung TV won't turn on

Equipment produced by the famous South Korean brand Samsung has always been considered one of the most reliable. However, even Premium class devices are not protected from breakdowns. Naturally, this also applies to television equipment.

Mostly, if a hardware component fails, then you need to seek help from qualified service center specialists. Since the average user cannot replace a faulty module on his own.

Less significant problems can be fixed on your own. No special skills or tools are required for this. The first and, perhaps, the most important stage of repair work is to find out why the Samsung TV does not turn on.

The diagnostic results will show the causes of the malfunction, therefore, the user will be able to make a final decision regarding subsequent actions. Depending on the complexity of the problem, you need to fix it yourself or contact specialized specialists.

Problem search algorithm

To determine why the Samsung won’t turn on, you first need to inspect the device for external damage, and only then move on to diagnosing the hardware component. Step-by-step algorithm for finding the problem:

Check the functionality of the outlet.
Assess the condition of the power cable, inspect it for kinks and abrasions.
Carefully examine the body of the TV; it is possible that the whole issue is due to mechanical damage to the panel.
Inspect the LED matrix; the main indicator of the failure of this part is dead pixels.
If any hardware component burns out, you will smell a burning smell.
If you have a special screwdriver, unscrew the bolts holding the back panel of the TV device. Visually inspect the boards; mechanical or thermal damage to the circuits is possible.
Channels switch with a delay or do not scroll through at all. In this case, it makes sense to install software updates. The Tizen operating system is decent software, but it is not without its drawbacks.

More thorough diagnostics can be carried out exclusively by certified specialists who know the arrangement system of the basic modules and have at their disposal professional equipment: spagers, multimeter, oscilloscope, etc.

If the TV does not turn on and the indicator blinks, then the problem is in the power circuit. This type of breakdown will be difficult to repair on your own.

What to do if the TV does not turn on

A TV, like any other complex equipment, may periodically malfunction. However, as a rule, there is no relationship with its service life. In some situations, when the Samsung TV does not turn on, the red light blinks or the monitor immediately goes off, the problem may be hidden in incorrect switching of the relay or other components. Such breakdowns are typical for old TVs with picture tubes. Newer LCD models are distinguished by complex fillings; accordingly, self-repair of such devices becomes more difficult. However, it all depends on whether there was a hardware failure, or the user was simply fiddly with the settings.

It is worth noting that in some situations you can actually troubleshoot problems yourself. However, in this case you need to be confident in your knowledge and not take unnecessary risks. First of all, you need to try to determine why the Samsung TV does not turn on. The malfunction can manifest itself in different ways.

How to solve the problem yourself?

Now let’s look at situations in which repairing a Samsung TV yourself will absolutely not harm the situation. Therefore, you can figure it out on your own without any hassle.

Problems with setting the standby mode. The display turns off, but in Standby the device continues to function. In this case, you need to pay attention to the panel LED; as a rule, it lights up red when in standby mode. To start the TV, you just need to exit standby mode by pressing the power button on the front panel of the device or on the remote control.
The remote control is broken. First you need to change the batteries and also check all the keys. You can always download a special application to your smartphone - TV-remote, as a result of which you can switch channels and adjust the volume using the most ordinary phone.
The socket is broken. If the indicator on the control panel does not light up, connect the TV to an alternative power source. After this, you can continue to use the device.
TV viewing is not available. It is likely that the occurrence 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 over-the-air TV, simply turn off all devices.
Low signal strength. Due to a weak signal, only a black screen is visible on the TV screen, often the reason for this is unfavorable weather conditions: excessive rainfall, thunderstorms, etc. Do not rush to take any action; it is likely that broadcasting 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 most often encounter.

Check TV mode

This topic has already been partially touched upon earlier, but now we will consider it in more detail. First you need to check what mode the television equipment is currently in. Standby – standby mode, its activation is indicated by a red indicator on the main panel. To resume TV broadcasting, you need to exit standby mode.

Experts strongly do not recommend leaving the TV in this mode for a long time. The thing is that the power supply circuits remain active, that is, they are energized. This means that if there is a voltage drop in the network, the power circuits will burn out. Of course, in the end the TV device will not turn on.

Thus, we figured out why the TV does not turn on, you just need to deactivate the Standby mode. In addition, be sure to turn off the TV by pressing the “Power” button, which is located on the front panel, to eliminate the possibility of burnt-out power circuits.

Check remote control

Why doesn't the remote control work? First you need to replace the batteries. Then you should check the keys; perhaps some of them are stuck and work only after several presses.

If the channels do not turn on the first time, then the problem probably lies in the failure of the infrared sensor. Such failures occur due to mechanical damage or liquid entering the device.

To control the TV with the remote control again, you need to buy a new one or replace it with a smartphone, having first downloaded and installed a special application, which we already talked about earlier.

Checking the outlet

If the indicator does not light and the device does not start either from the remote control or from the key located on the front panel, then you need to check the functionality of the socket. It is likely that the TV does not turn on precisely because of it.

Of course, you should first connect the equipment to an alternative power source (to another outlet or extension cord); if there is no result, then contact a service center, since you absolutely will not be able to repair the elements of the power system yourself.

Another source selected

If you want to watch terrestrial TV, but there is no picture, then check whether you have selected the correct signal source. It is likely that an HDMI cable is connected to the TV, in which case you need to turn it off and activate the connection to the antenna.

Why doesn't my LCD TV turn on?

Almost all modern TVs today are equipped with LCD screens. If your Samsung TV does not turn on, the indicator blinks or constantly goes out, then first of all you need to pay attention to several of the most common signs of a malfunction. Most often they are associated with a broken remote control. If the indicator lights up, then most likely the batteries installed in the device have expired. It may also not turn on due to incorrect mode or improper use of the extension cord. Also, many people encounter this problem when connecting a computer to a TV.

When to contact a service center

Hardware failures on a Samsung TV can only be fixed by a professional engineer. The average user will be able to solve external problems, so disassembling the device yourself is by no means a good idea.

Software malfunctions of Samsung Smart TV are also not always possible to fix with your own hands. To update the firmware, you must first download it and save it to a flash drive or built-in hard drive. Not every user can cope with such a task.

Service center engineers have special equipment at their disposal and also know how to properly disassemble the TV. Now let’s look at the situations in which you need to contact the experts.

The TV does not turn on from the panel button

If the TV does not start after pressing the power button located on the panel, you should pay attention to the standby indicator. For example, if it turns off when the button is pressed, this indicates that the internal locking has been activated.

Do not rule out damage to the button itself or the cable that provides the connection. If, when pressed, the button literally falls into the panel and does not click, then it needs to be replaced. You absolutely won’t be able to do this yourself, so you just need to call a specialist.

The indicator lights up red

If the light is red but the TV does not turn on, this means that it is in standby mode. We have already figured out how to fix this problem. In some situations, the indicator glows green, but then turns red again. This indicates that the central processor generated and sent out an incoming signal to turn on to other modules.

Due to the fact that one of the nodes breaks, the command is not executed. For example, the problem lies in the power supply, so the TV does not start. The central processor does not receive confirmation that the command has been executed, as a result of which it cancels the signal to turn on the TV, returning the device to sleep mode.

The LED may constantly change color, but the TV will not turn on. The cause of the malfunction is the inverter or transistor. You need to contact the service center to have specialists replace the faulty modules.

The indicator is green, but the TV does not turn on

If the indicator lights up green, but the TV does not turn on, then specialists will conduct a thorough diagnosis. The check begins with testing the motherboard; in particular, the incoming voltage is measured using special equipment. In addition, the execution of commands to illuminate indicators, turn on the TV, etc. is tested.

When the light comes on, indicating operation, but no signals are received from the main board, this may indicate problems with the software. Try to turn on the device using the remote control or by pressing the button located on the main panel.

A hardware failure of the motherboard can be resolved by replacing the faulty component. If the voltage is completely fine, then the specialists will reset the user settings and then install the updated software.

The indicator flashes regularly

A constantly flashing light is an indicator of a failure, but you need to specify the problem, which can be very difficult. To determine the cause of the blinking indicator on the TV, a comprehensive diagnosis is carried out. Using an oscilloscope, the power adapter is checked, and the performance of the converter, which is located on the motherboard, is also tested.

Often the red light blinks due to voltage problems. For example, there was a short circuit in the contact circuit.

The TV takes a long time to turn on

If the television equipment takes an unusually long time to turn on, this indicates a malfunction of a particular unit. For example, if you use a device with a liquid crystal matrix, then the factors will differ significantly from the same LED models.

Determining why the TV does not work well and does not turn on immediately is extremely difficult, especially if you do not have experience in repairing equipment. Considering the circumstances, it is more advisable to contact a service center, whose employees will be able to quickly determine the cause of the malfunction and normalize the correct operation of the device. They use not only professional equipment, but also licensed software.

Other breakdowns

In addition to direct damage to the TV, there are malfunctions of additional elements:

Voltage surges. With any power surge there is a possibility of breakdown. Even when the TV is turned off, some components continue to use energy. Therefore, it is recommended to turn off all operating devices during a thunderstorm. This problem can be resolved by using a voltage stabilizer.
The remote control is broken. Before you start checking the TV, you need to make sure the remote control is working. Press the buttons, replace the batteries. For a working device, the indicator will blink each time you press it. If the remote control is broken, you can use the control panel or control it using your smartphone to turn it on.
Access problems. If child lock has been set, the control panel on the TV itself is locked and does not respond to any pressure. In this case, you need to use a remote control, without which it is impossible to disable the lock.
Constant reboot. The functionality of Smart TV may be impaired due to a technical failure or incorrect installation of the update. First, you should try to reinstall the firmware yourself. If this does not help, a complete diagnosis of the equipment is needed.

Other problems, such as problems with the backlight or a broken power key on the TV, cannot be fixed on your own. They often occur due to power outages.

Recommendations

Connect equipment through a voltage stabilizer. The protective device will protect not only television equipment from power surges in the network, but also other household appliances.
When the first malfunctions occur in the operation of the television panel, immediately disconnect the device from the network. “Bad” signs include regular clicking sounds and a burning stench.
If the TV receiver is “flat”, do not place it close to the wall. Especially if the wall is covered with carpet. The equipment gets quite hot inside. Hot air needs to escape through vents at the back of the case.
It is better to eliminate periodically occurring failures immediately. Over time, the problem may worsen, and the TV receiver will no longer turn on completely.
Do not unplug the cord from the outlet while TV is on. First turn off the device using the remote control.
Let's "rest" the TV set to cool down. If you go away for a long time and leave the panel on, in the settings, enable the function to automatically turn off after a certain period of inactivity. So, if no button is pressed, for example, for two hours, the TV will go into standby mode.

Types of faults

TVs can have different problems that cause approximately the same “symptoms”. In this case, the devices need to quickly fix the problem.

The indicator flashes red.
The TV clicks, hums, hisses or whistles.
The indicator doesn't work at all.
The TV does not turn on, the light is on.

You can learn what to do in each specific situation from this article. But you need to remember that, as a rule, the same characteristic of a broken device will be either a lack of response to the remote control, or a complete shutdown when the power supply is turned on.

Infinite reboot

This malfunction is typical for Samsung devices that support Smart-TV technology: endless rebooting is a consequence of a firmware failure or unsuccessful update. Any user can perform flashing: just follow the instructions that are included in the factory kit for the device.

Consultation with a service center will be required if reinstalling the software does not produce the expected results: a thorough diagnosis of the device and a targeted set of repair work will probably be required.
