Samsung TV receiver can have many problems, and the skilled help of the master is not always required for their elimination. For example, if the Samsung TV does not turn on, then do-it-yourself repair in some cases is still possible.
If the equipment does not turn on or does not behave as it should, it makes sense to try to find out the cause of the breakdown yourself without involving service center specialists. The latter will have to pay a lot of money, while a small problem can be completely eliminated on their own.
Important! If the TV is under warranty, then self repair is out of the question. Opening the case, breaking factory seals and other actions automatically deprive the consumer of all service privileges.
Network cable and socket
First of all, you need to check the status of the network cable and outlet. The first is inspected visually on physical damage. The outlet can be checked by connecting another household appliance to it, for example, a lamp.
Manufacturers, in pursuit of lightness and refinement of the design, turn a blind eye to the protection of the case. Some models are so fragile that the outer plastic crumbles when pressed hard. Carefully inspect the enclosure. for chips, dents and other mechanical damage.
Particular attention should be paid to the screen: even microcracks that are barely visible to the eye can affect the quality of the picture. It can also be attributed to defective pixels. To diagnose the latter, special tests are provided in the firmware that identify dark or bright points on the screen.

Power surges are one of the most common causes of failure of TV equipment. Boards and individual elements can burn out and exude a specific smell. You can catch it by sniffing at the back of the TV.
Inspection board inspection
If the warranty period has already expired, and a visual inspection of the external part of the equipment did not give results, then you can try to open the case and look for problems on the main board. Is worth pay attention to contacts, wires and groups of microcircuits: open circuit, thermal effect, excess moisture or corrosion.
Operating system diagnostics
Problems can be not only in hardware but also in software. It happens that the firmware starts to fail and in every way to fail. This, for example, can manifest itself in a noticeable delay between switching channels or independently performing certain actions without user intervention.

Only decision. installing new firmware. If the TV is connected to the network, then the current update can be received “over the air” by looking at the appropriate settings section. In other cases, you will have to copy the firmware to a flash drive and install it manually.
When the wizard’s help is not required
Very often, owners of television sets panic and begin to call the master at the slightest problem with their device. But if you calm down and take a sober look at the situation, then there may not be a breakdown of equipment. It is required to check the behavior of the television receiver for some symptoms.
You need to check what mode the TV is in. For instance, standby mode. This is the standby mode, and you can find out about its on state by looking at whether the red light on the unit panel is on. It should be remembered that leaving the television receiver in this mode for a long period of time is not recommended, since with the seemingly disconnected unit, all the power supply circuits remain energized. If the mains power happens power surge, then all primary circuits will burn out, after which the television receiver will refuse to turn on. Therefore, the unit should be turned off using the button located on its panel to reduce the risk of burnout of the electronics.
Inoperative Remote Control
In the case when you watch the indication, but the TV does not respond to commands from the remote control, you can try to turn on the device using control panel, located on it. If you succeed, then the remote control is faulty. Although, in principle, it cannot break, unless, from a fall, a quartz resonator can break, which will have to be replaced. Most often, in the remote control the batteries are low or empty. In any case, it is worth disassembling the remote control and try to fix the malfunction of the remote control with your own hands.

No standby indication
In a situation where there is no indication, and when the button is pressed, nothing happens, you do not hear clicks and do not notice the blinking of the LED, then we can assume that malfunctioning outlet. Of course, you can try to connect the device to another power source, but if this does not help, then, without special knowledge and qualifications, you can’t repair the television yourself with your own hands. Even replacing a conventional fuse will cause you difficulties, because in modern TVs they are not so easy to find. Consequently, calling the wizard will be the right decision.
The indicator blinks once
If a one-time blinking of the indicator was noticed, after which it continues to light up steadily, or its color has changed, this may mean that the device is in working mode: either AV, or in PC connection mode. Therefore, you will need to transfer the unit to TV reception mode.
Inadvertently, some specific TV features could be activated. For example, child protection, blocking the inclusion of technology without a remote control. It is worthwhile to carefully study the settings for the running functionality of such a plan. An extreme case is resetting to factory settings.

Rain, heavy snow and other bad weather affects the quality of the broadcast signal. Ripples, artifacts, or noise appear on the screen. It is necessary to wait for the end of the weather, and if the situation has not changed, then check the antenna (plug, cable, housing).
This problem is especially relevant in private homes. Strong jumps can damage any household appliance. To avoid such troubles, it is worth getting special equipment. voltage stabilizer.
If the equipment turns off almost immediately after switching on, then the matter may be in the button. Other symptoms of the latter malfunction. a loud click when activated and an idle indication. You can replace the power button yourself, fortunately, many manufacturers have implemented this feature in their models.
This is a typical platform crash. Problem is treated updating firmware to the current version or reinstalling it completely.
When the help of a telemaster is required
Everything that can be done by a non-specialist in teletechnics is limited to checking elements that are outside the device. In other cases, opening the device with your own hand is not recommended, and you can not do without a wizard.
The device did not turn on from the panel
If you didn’t succeed in turning on the TV from the control panel, you need to observe the behavior of the standby indicator (it normally lights up steadily, more often. red). If it turns off when you try to press a button, then the problem should be sought deeper in the device, as this indicates internal lock operation (not to be confused with the child lock mode, which is activated by the user). This happens when one of the modules fails. In some telecom models, when a lock is triggered, you can hear a click sound. You will not be able to fix such a breakdown yourself. The only reasonable way out is to call a specialist.
Samsung TV power button
The indicator turns green and then turns red again
Such color switching indicates that the CPU generated a signal to turn on the device, and it was sent to all modules for its execution. If any module failed, then he cannot execute the command. For example, a failure in the power supply does not allow it to go into the desired mode. In this case, the processor, without receiving confirmation from the power supply about normal operation, sends a signal to cancel the inclusion of the television receiver and returns it to sleep mode.
Such flashing can continue for a long time until the main cause of the failure is removed: the inverter is repaired, the transistor is replaced (for example, on the s62 chassis), the power supply is moved, or another of a large number of reasons.
The indicator turns green and nothing happens.
When the indicator lights up in green, and the television receiver does not think to turn on, this situation can be called ambiguous. Is required main board check with the measurement of the voltage supplied to it. There is also a study of commands to launch, highlight, etc.
If the light turns on, signaling the working state, but there are no signals from the main board, while the device does not respond to the remote control and pressing the buttons on the case, this may indicate software crash. Only flashing and updating the software will be able to return the motherboard to normal operation.
The indicator flashes randomly
This behavior of the indicator indicates that a failure has occurred in the TV set, and it carries no more useful information. Required complete diagnostics of electronics, starting with the “ringing” of the power supply and ending with the converters located on the system board.
TV turns on for a long time
When it takes a long time to turn on the television, this indicates that some unit of the unit has failed. For televisions with a kinescope and LCD panels, the occurrence of damage can vary greatly. Identifying a malfunction without having the necessary experience and knowledge is not easy enough. Since the problematic unit still starts to work, and only a qualified master can get to the bottom of the cause of the failure, using special equipment to perform the necessary measurements. In some cases, you will need to check the device in the service center on the stand, using special software.
As you can see from the above possible reasons why the TV stopped turning on, there are not so many options for repairing it on your own. This rule also applies to the case when the TV itself turns on and immediately turns off. And since the unit is a complex electronic device, it requires accuracy in operation and timely after-sales service.
