The TV does not turn on, the indicator goes out. Samsung TV does not turn on, the red light is flashing: possible causes and their elimination

There are many nuances to the malfunction, but its essence is simple - the TV does not turn on or, as if it turns on, but does not give out any sound or image (it is found in any type of TV - in LCD, plasma, kinescope).

In this case, there may be various options:

• The indicator (light) flashes, the TV does not turn on. Sometimes the LED flashes a certain number of times - this is a kind of self-diagnosis. A different number of blinks indicates different problems.
• The indicator is constantly on, the TV does not turn on and does not respond to any actions.
• No lights are on, TV is not working.
• There are side sounds (something clicks, chirps, rumbles, makes a strange noise).

Why did the TV stop turning on?

• The most common reason is "of course". This happens in 90% of cases.
• Due to power surge.
• Because of some cotton inside, after which it can smell burnt.

What is required to troubleshoot

Self-repair is dangerous!

Unskilled repairs can lead to a fatal breakdown and the release of equipment in the trash. Trust only professionals.

Like any technology, the TV tends to malfunction, and regardless of the period of its operation. For example, in some cases the TV does not turn on, but the indicator blinks and the relay clicks. Many other symptoms are also possible. So, let's look at why the TV does not want to work, and what to do in certain cases?

Common Causes of Malfunction

The problem can manifest itself in several ways and is manifested by the following possible symptoms:

• The LED indicator flashes but the TV does not turn on.
• The indicator is red, and the device is not controlled from the remote control and does not turn on at all.
• The indicator does not light up and the TV does not turn on with the remote control.
• The TV clicks, buzzes, makes strange sounds, but does not turn on.

Televisions by their type can be divided into three main varieties: kinescope, plasma and liquid crystal. Despite notable differences in size, appearance and the method of displaying the picture on the screen, the reasons that do not allow the device to turn on are absolutely identical. They do not depend on the type of television receiver.

Flashing indicator

If the indicator blinks, then the TV itself is diagnosing the type of problem. Normally the red light flashes a certain number of times. In this case, you need to open the operating instructions for the device and find the section where the types of malfunctions and their indication are indicated. And, based on this, take the necessary actions.

Another option that can cause a similar symptom is the TV connected to the computer as a monitor. If the connected computer is in "sleep mode" or turned off, the device will flash for a few seconds when turned on from the remote control. Alternatively, the TV is connected as a second monitor, but not as the main one.

You need to bring the computer out of Stand By mode (move the mouse or press a button on the keyboard) or start it by pressing the power button. In fact, the TV works. It just doesn't display an image.

The indicator is constantly on

If the LED is lit, this indicates that power is being supplied to the control unit. If the TV receives signals from the remote control remote control does not react in any way, the first thing to do is to try to turn it on directly using the panel buttons. Perhaps the malfunction lies precisely in the incorrect operation of the remote control, and not the TV itself. If this is indeed the case, then you need to take the following steps:

• Check batteries and contacts for oxidation.
• Make sure the integrity of the emitter and the absence of sticking of the remote control buttons.
• If possible, disassemble and clean the remote inside from dust.
• If the remote control was filled with liquid and stopped working, send it in for repair or purchase a new one (preferably the original one - it will last longer).

If it was not possible to start the TV from the panel, two scenarios are likely.

Protection worked

In this case, the TV may try to start, but after a few seconds the screen goes blank, or it may not turn on at all. The main cause of this problem in most cases is power outages in the home network. These can be power surges or power cuts and turns on while the TV is in “sleep mode”.

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

Processor or control failure

The diagram shows that the LED indicators are controlled via the Stand By wire and the Q211 transistor. When a short circuit occurs, the TV stops turning on.

In such a case, it will not do without contacting service specialists. Attempts to carry out complex repairs on your own can completely disable the TV.

The indicator is off, the TV does not turn on

Such symptoms most often indicate that the cause of the malfunction is a lack of power. If the light bulb just “burned out”, the TV would work in normal mode, but without indication. Do not worry ahead of time and call the master. Initially, it is necessary to exclude all variants of the problem that are available for self-correction. Moreover, in a large number of cases the problem is caused by rather banal reasons, including:

• No power at electrical outlet. The circuit breaker in the shield may turn off, or the socket may be faulty. It is checked using a conventional indicator screwdriver or a tester. If there is no power, the machine is inspected. Even if it is on, it is better to “click” it several times. Did not help? You need to look for a problem in the outlet or wiring yourself or with the help of an electrician.
• Extension cord failure (if the connection is through it). When a direct connection to the outlet ensures the normal operation of the TV, and there is no power through the extension cord, that's the point. If it is a surge protector, you need to check the power key and fuse. In any case, you need a working device to fix the problem.
• Network button on TV turned off . Almost all models modern TVs when the "Network" button is disabled (it can be located at the bottom, side or on the back of the TV), it becomes impossible to control the device from the remote control. It is necessary to activate the On/Off button on the control panel.
• Wrong mode selected . The TV in this case works absolutely fine, but if one of the modes, for example, AV, PC or Receiver, is not used, the screen dims and may enter “sleep mode”. You need to select the TV function again, and the picture will return.
• Any part malfunction . This may be a microcircuit or a capacitor, or perhaps a power supply or control system (for example, a button has broken). Testing the performance of various components of the TV and carrying out the necessary repairs is best entrusted to the specialists of the appropriate service center.
• Blown fuse . For kinescope TVs, this is the actual reason for the lack of power. If it is located in an accessible place, it is quite possible to replace it yourself.

Extraneous sounds when the TV is not working and there is no indication

Sometimes TV owners are faced with clicking or other sounds inside. Symptoms may vary:

• The TV did not turn on, the indicator blinks, the relay clicks.
• The light is not on, the TV clicks.
• The TV beeps and does not turn on.

The most common causes of clicks on TVs are:

• Activation of the locking system . In the event of certain types of malfunctions (power supply or other units), the protective function is activated. It is designed to avoid more serious damage in case of malfunctions. It is the blocker that makes characteristic clicks when the TV tries to turn on.
• Heating and cooling of plastic body parts . So, even a working TV can click.
• Signaling about the activated (not used for a long time) operating mode for the selected source . At the same time, TVs may squeak or whistle.
The reason may be a transformer, microcircuit or transistors. In this case, the TV does not turn on at all. You can't do without a qualified master here.

TV does not turn on, protection works (video)

In this video you will clearly see how the protection works when the TV does not turn on. At the same time, the wizard tells how to fix the problem.

If the TV does not turn on, this does not mean that it is faulty. The first step is to diagnose the cause. If a complex problem is established, for example, a breakdown in the power supply, it is worth contacting a qualified, or better authorized service, for help.

In contact with

Any TV, regardless of its age, tends to break down. For example, sometimes the TV does not turn on, the indicator blinks, the relay clicks. Other symptoms are possible, but the result is the same - TV repairs will be required. Let's look at the common causes of a breakdown, which can manifest itself in several ways. What are its symptoms? This is when the LED indicator flashes, but the TV does not turn on, the indicator glows red, but there is no control from the remote control and the TV does not turn on at all, the indicator does not light up and the TV does not turn on from the remote control, you can hear it clicking, making strange sounds. All these symptoms indicate that TV repair is guaranteed to be required in service center. 1. The indicator flashes. If this happens, respectively, the TV itself tries to diagnose the problem. Typically, the red light will flash a certain number of times. Another option that can cause this kind of symptom is when the TV is connected to a PC as a monitor. 2. The indicator is constantly on. When the LED is lit, it means that power is being supplied to the control unit. If the TV does not respond to signals from the remote control, you should turn it on using the buttons on the panel. It is possible that the failure is in the incorrect operation of the remote control. Otherwise, the TV needs to be repaired. If starting the TV from the panel did not work, there are two options here. The first - the protection worked. In this case, the device may start, but the screen will turn off after a few seconds, or it will not turn on at all. The reason for this situation may be power outages in the network, power surges at the moment when the TV is in “sleep mode”. The solution to the problem may be to turn off the TV from the network. If the voltage problem is persistent, you should use a stabilizer, UPS or surge protector. This will avoid repairing TVs in the future. The second is the failure of the processor or control. If a short circuit occurs, the TV will not turn on. In this case, it is guaranteed that the TV will need to be repaired. 3. The indicator does not light up, the TV does not turn on. Such symptoms are usually evidence that the cause of the breakdown is a lack of power. If the light bulb “burned out”, the TV would work in normal mode, with no indication. In most cases, this problem can be caused by reasons such as the lack of power in the electrical outlet. Perhaps the circuit breaker turned off in the shield, or maybe the socket itself is faulty. There may be other reasons why you need to repair any TV models in Kyiv.

In an outdated Grundig GR-1450TX TV, when you turn on the strip on the screen.

A TV with a 37 cm kinescope was delivered to our service center, which has long been outdated. There was a malfunction in it - when you turn on the bright white screen, stripes appeared. The user requested that the TVs be repaired. As a rule, we never refuse our customers, even if the TV is many years old and has been intensively used. A malfunction such as this can be caused by several factors, however, diagnostics are required to accurately determine them. Having completed it, the telemaster found out that two modules failed at the same time - power supply and SR. In this case, the repair of TVs consisted in the resumption of the operability of these nodes. I had to replace and solder many different parts, including C 22.0 * 250 V, 47.0 * 50 V and others. After all the work, the image is good, the stripes are gone.

The photo, which captured the TV from the back, shows that it is quite outdated, both structurally and functionally. Despite this, the sticker with the serial number, model and other information has been preserved, it is well readable. This TV is made in Germany, this is also indicated on the label. The device has one connector at the bottom. In general, the case is not damaged, it is in good condition, except for the dust that has accumulated in the ventilation grilles. We undertake TV repairs, even if they are hopelessly outdated.

To make it possible to repair TVs, the master needs to disassemble it. In the photo, this TV is already without a back cover. The kinescope board is in place, it is not damaged. Since this TV has not been repaired before, over the years of operation (at least 10 years) quite a lot of dust has accumulated inside, especially on parts, circuit boards and wires.

There is a lot of dust on the board on which it is necessary to repair TVs, it is almost impossible to read the markings on the details. This greatly complicates any restoration work. That is why general prevention is required.

Another photo from a close distance, as confirmation of the above. It is really difficult to make out the markings here because of the layer of dust. During the diagnostic work, the telemaster found out that the problem is in the power modules and the CP. That is why the repair of TVs in the restoration of these components. This is a complex work, therefore, it must be carried out exclusively in the stationary conditions of the service center, by experienced telehandlers.

At this stage, the repair of TVs was not completed, since many different passive elements had to be soldered. So, such parts as C 22.0 * 250 V, 47.0 * 50 V and others were replaced. Now this Grundig GR-1450TX kinescope CRT TV is fully operational, the stripes on the screen have completely disappeared.

Squeaky sound in all modes on a JVC AV-2584VE flat screen CRT TV.

The JVC AV-2584VE flat-screen CRT TV has a squeaky sound in all modes. The user who brought it to our service center explained that they tried to connect the DVD and the Tuner, but the situation did not change. This model has a screen diagonal of 25 "and a 4:3 aspect ratio. The device is equipped with one independent TV tuner, it uses acoustic system 20W (2x10W). The model is endowed with AV connectors and a headphone jack. In this case, the power supply module failed, so the TV repair was aimed at ensuring that this node was restored. This is not a simple breakdown, so experienced, knowledgeable TV technicians should be involved in repairs. Along with this, preventive maintenance of the device was carried out, many original parts were replaced and re-soldered.

In the photo, where this TV was filmed from the back, it is clearly seen that it is in good condition, its body is not damaged anywhere. The label with all the information about this TV is in place, everything is perfectly readable on it (serial number, model, etc. information). This, in turn, greatly helps in the repair of TVs.

Televisions and television have firmly entered our lives. Today it is the most common type. family leisure, and, of course, in the event of a TV breakdown, you are unlikely to want to give up your usual entertainment.

In this article, we will tell you what to do if the TV does not turn on.

Why won't the TV turn on?

If the TV clicks and does not turn on, first of all, it is necessary to determine the nature of the clicks. A single sound when turned on is not considered a defect - depending on the model, the click volume may be high or low.

Case parts can also click if they are made of low-quality (low-plastic) material. This happens due to the heating and cooling of the body parts. This is also not a defect, although it irritates many users a lot.

If the TV does not turn on and clicks at the same time, most likely the problems are related to the power supply, which is blocking the operation of the device. If a clicking sound is heard after the TV is turned on, and immediately stops after it is turned off, there may be a problem with the power supply or other indoor units. The same can be said if the TV does not turn on after a thunderstorm - most likely, one of the internal blocks or boards has burned out. It is undesirable to repair such breakdowns on your own - a specialist will fix them quite quickly, but unqualified repairs can further aggravate the situation, as a result of which you will have to throw the TV in the trash.

Sometimes the cause of clicks can be static electricity that accumulates on the surface of the device along with dust. Wipe the TV with a damp cloth (not wet) or a special dust remover, the clicks may stop.

If the TV beeps and does not turn on, first determine the source of the sound.

If the TV does not turn on with the remote, check the batteries first. Perhaps the reason is not in the TV, but in the remote control. This probability is especially high if the TV does not turn on, and the indicator on the case is on (blinking). If the remote control and batteries are OK, check if the TV is in standby mode. This is evidenced by a luminous indicator lamp on the case. If the indicator is not lit, check that the device is plugged into an outlet and press the power button on the case.

If the TV does not turn on for a long time, immediately contact the service center. It is very difficult to identify a breakdown on your own - after all, the part that impedes the operation of the device still enters the operating mode, which means that only an experienced specialist can find it.

What to do if the new TV does not turn on

The chance of being completely broken is pretty low. Before contacting the seller with claims, slowly and carefully re-read the instructions and check all the connection steps. Do not forget to also check the serviceability of the socket and connecting cables (wires).

As you can see, there are many options for TV breakdowns. We do not recommend that you try to fix a broken device yourself, because you can not only break it completely, but also endanger yourself. The result of inept intervention may be a fire or even an explosion of the device. It is better to contact a specialized repair center - it will be safer, more reliable and faster.

There can be many malfunctions in a Samsung television receiver, and qualified help from a wizard is not always required to fix them. For example, if the Samsung TV does not turn on, then do-it-yourself repair is still possible in some cases.

To search for breakdowns in any household appliances there is a certain sequence of search for problems. Repairs are no exception. Samsung TVs, for which the search for possible breakdowns starts from the outlet and continues in the power supply. Next, the switching board and processor module, sweep and synchronization module, etc. are examined. The study may end in the control unit, troubleshooting in the stabilizer or finding a failed transistor in the line scan module. Find it all without opening the receiver– impossible, and the normal owner of the device will not be able to fix such a problem.

If the TV is fresh from the store, then the likelihood that it is faulty is extremely small. The reason may be your inattention, and you did something wrong. Recommended to read carefully instructions for the device. But if it was already in operation and suddenly stopped responding when you tried to turn it on, then searching for the cause of the failure by certain signs will help you decide whether to contact the service or you can handle it yourself.

When the help of the master is not required

Very often, the owners of television receivers 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.

Mode check

You need to check what mode the TV is in. For example, - this is the standby mode of the telly, 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 it is not recommended to leave the television receiver in this mode for a long time, since with the unit seemingly turned off, all power supply circuits remain energized. If the power supply network power surge, then all primary circuits will burn out, after which the TV receiver will refuse to turn on. Therefore, the unit should be turned off with the button located on its panel in order to reduce the risk of burnout of the electronics.

Non-working remote control

In the case when you observe the indication, but the TV set 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 succeeded, then the remote control is faulty. Although, in principle, it cannot break, except that, from a fall, a quartz resonator can break, which will have to be replaced. Most often, in the PDU low or low batteries. In any case, it’s worth disassembling the remote control and trying to troubleshoot the remote control with your own hands.

No standby indication

In a situation where there is no indication, and when you press the button nothing happens, you do not hear clicks and do not notice the blinking of the LED, then we can assume that the socket is faulty. Of course, you can try to connect the device to a different power source, but if this does not help, then, without special knowledge and qualifications, you will not be able to repair the TV receiver with your own hands. Even replacing an ordinary fuse will cause you difficulties, since they are not so easy to find on modern TVs. Therefore, calling the master will be the right decision.

A single blinking of the indicator is noticed

If a single blinking of the indicator was noticed, after which it continues to burn with a steady light, or its color has changed, this may mean that the device is in operating mode: either AV or PC connection mode. Therefore, you need to translate the unit to TV reception mode. In addition, the TV can be blocked from unauthorized use (for example, by children) - in this case, you need to unlock it using the instructions for the technique.

Please note: if an antenna is not connected to the TV receiver, the TV signal is very weak or it is absent at all, then the TV set may enter monitor mode after noise suppression. That is, you will see a black screen without sound.

When You Need the Help of a TV Technician

Everything that a non-specialist in teletechnics can do is limited to checking elements outside the device. In other cases, it is not recommended to open the device with your own hands, and you cannot do without a wizard.

The device did not turn on from the panel

If you can’t turn on the TV from the control panel, then you need to observe the behavior of the standby indicator (normally it lights up with a steady light, more often red). If it turns off when you try to press the button, then the problem should be looked for deeper in the device, as this indicates interlock operation(not to be confused with the child lock mode, which is enabled by the user). This happens when one of the modules fails. In some models of TV sets, when the lock is activated, you can hear the sound of a click. You will not be able to fix such a breakdown yourself. The only reasonable way out is to call a specialist.

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 is out of order, then he cannot execute the command. For example, a failure in the power supply does not allow it to enter the desired mode. In this case, the processor, without receiving confirmation from the power unit about normal operation, gives a signal to cancel the inclusion of the TV 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 has been repaired, the transistor has been replaced (for example, on the s62 chassis), the power supply has been moved, or another of a large number of reasons.

The indicator turns green and nothing happens

When the indicator is green, and the TV set does not even think of turning on, then this situation can be called ambiguous. Required main board check measuring the applied voltage. Also, a study of commands for starting, lighting, etc. is being carried out.

If the light turns on, signaling the working condition, 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, then this may indicate software failure. Only a flashing and software update 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 does not carry any 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 TV receiver, this indicates that any unit of the unit has failed. For TVs with a kinescope and LCD panels, the factors for the appearance of a breakdown can be very different. To identify a malfunction without having the necessary experience and knowledge is quite difficult. Since the problematic unit still starts working, and only a qualified master can get to the bottom of the cause of the failure, using special equipment to carry out the necessary measurements. In some cases it will be necessary to check the device at the service center at the stand, using special software.

As can be seen from the above possible reasons why the TV stopped turning on, in order to repair it on your own there aren't many options left. 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 during operation and timely service.
