LG TV does not turn on: light is flashing

Like any home appliance, TVs are prone to malfunction. This can happen regardless of the period of operation of the device and the manufacturer.

When the relay indicator blinks, then LG TVs of the 42pa4510, ld33b, 42ld650, 42la621v series themselves give a signal that the device has a problem. Usually the red light should flash a certain number of times. You just have to open the user manual and find the section in which the types of breakdowns and their indication are indicated, with which the device reacts to the problem.

Another option that can cause a similar symptom appears when a computer is connected to the TV as a monitor, or a player. If the latter went into “sleep mode”, or maybe completely turned off, then the TV, when turned on by the remote control, will beep for a few seconds by the indicator.

Overheating of internal parts or the TV case is a very common problem for modern appliances. In this case, the failure to turn on the device, a dark indicator and clicks will make themselves felt even in a working model. Let the appliance rest for a couple of hours and everything will work out. Also, the TVs will whistle, and the indicator will not turn on if the power supply is too heavily loaded. By replacing the transformer, transistor or microcircuit, you can solve the problem. If the old TV set goes out, or the old TV set goes out, then the master should look for the reasons here.

Mystery TV does not turn on blue indicator is on

The TV does not turn on. a situation in which it is necessary to understand and find the reason. As soon as television firmly entered our homes and became widespread, it radically changed a person’s life, his leisure time and outlook on life. And now, if something happens to the TV, a real panic begins for many. What to do when suddenly a failure occurs and the TV does not turn on, and the LED blinks or does not light up?

Samsung TV does not turn on: red light blinks and beeps

Before you start troubleshooting, you must try to turn on the TV again. It is very possible that the problem is hidden in the power button, if for some reason it did not work stably. The indicator light may or may not be on. In view of this, special attention should be paid to it.

Many of those who have purchased a Samsung TV of the le40r81b, le32r81b, le23r51b, le40s62b, le20s52bp models are faced with the problem of not turning on the TV. In this case, the light is on, but there is no damage. Don’t panic. In addition, you need to understand that the fault is not in the manufacturer of the equipment. A similar nuisance can happen to a product of any brand.

One of the most commonplace problems is a breakdown in the outlet or, in general, the reason for the blackout. You need to analyze the wiring for faults. Perhaps the breakdown lies in the shield or connector, which simply turned off or stopped working from a power surge. Sometimes the reason lies in the complete lack of electricity. You can check the outlet by plugging in another device or appliance. If there is no food in the whole apartment, then it is necessary to inspect the machines. If everything works for the neighbors, and your apartment is de-energized, and you have not identified any visual reasons, you need to contact a specialist. Let the master on duty take the necessary measures himself.

If the TV does not turn on and the indicator does not light up, you should check the condition of the outlet

If the TV does not turn on and the indicator is off, you should:

  • Check the serviceability of the outlet into which the device is connected;
  • Analyze the integrity of the device’s network cable;
  • Check the voltage in the network throughout the apartment;
  • Asking if neighbors have tension.

Only if there is a positive answer to all questions, it can be assumed that the malfunction must be looked for in the device itself.

A modern TV does not turn on, and the indicator is on: what to do

If the TV does not turn on, it is best to contact a service center. But, if today is a day off, or trouble happened in the evening, then you can try to fix the problem yourself. First of all, you need to conduct a preliminary inspection of the equipment.

The instructions supplied with the device give full recommendations on this matter, and how to eliminate some basic, especially frequent and easy breakdowns. Sometimes the problem of not turning on the TV may lie in the wrong connection of the device, and the fact that the shutdown button is accidentally pressed, or the shutdown button may be damaged. Could also burn out the power supply.

Before looking for a solution to fix the problem, you need to determine exactly what kind of device you have: LCD, plasma TV, or CRT. Currently, liquid crystal, CRT, and plasma devices are produced. If one of them breaks down, there will be no special differences in the repair, because the difference lies only in the “design”, and the internal structure of the device remains the same.

In case the TV does not turn on, it is best to contact the service center for help.

TVs almost always have various problems, but at first glance they all have approximately the same symptoms:

  • The indicator constantly blinks red and green;
  • The device clicks, hums, pops or whistles;
  • The indicator light does not work at all;
  • The TV does not turn on, but the indicator lights up blue.

A broken device will be equally characterized by an immediate lack of reaction to pressing the buttons on the remote control, and a complete shutdown while the power supply is turned on. If the plasma does not start immediately, try again.

Why Philips TV does not turn on: what to look for the problem

If the light is on, but the TV does not turn on, then we can assume that the consumer has incorrectly applied the active mode. Many of the latest devices have features that allow you to enter a “sleep” state. With this turn of events, the TV must respond to the remote control. You just need to go to the menu and turn on the “TV” mode.

In case your Philipstea1507p TV is connected via an extension cable, it is worth checking if any parts are damaged, like microcircuits or a capacitor, or the power supply and buttons. In this case, it is best not to try to fix the problem yourself. Your wrong actions can only harm the device even more.

If you intend, nevertheless, to try to fix the device on your own, then read the instructions carefully and follow only its instructions. Start by trying to turn the TV off and on again. If your TV model is relatively new, and purchased recently, then it should not have global problems. The simplest breakdown can be a faulty power button. It may just be disabled. If the indicator light on the TV is on, but the device itself does not turn on, then everything is in order with the power supply, it is just that the device did not turn on the first time. Don’t look for other reasons yet, just try restarting your device.

Philips TV may not turn on because it is set to sleep mode

In order to start the system, try the following steps:

  • If the indicator does not turn on from the remote control, then try to turn on the device directly from the control panel of the TV itself. Perhaps you just have a faulty remote control, or it has run out of batteries.
  • When the TV does not want to turn on from the TV panel, then you need to pay attention to the standby indicator.
  • A dark screen will also be with a weak transmitted signal, or if the antenna is poorly plugged in.
  • Sometimes after turning on, the TV screen lights up, and after a few seconds it turns off again. This may mean that one of the device’s microcircuits is broken, and its quick shutdown is a simple protective function. If the device goes into protection, you should call the telemaster.

If the TV turns on for a long time, then the cause may be a malfunction of one of the television units. Different models of TVs can have very different breakdowns. It is difficult to find serious faults without proper experience. It is better to give it to a specialist for repair.

The TV beeps and does not turn on

Television, today, is one of the most popular ways of recreation and leisure. And its serviceability worries all residents of the house. In order to avoid serious problems with this type of equipment, it is necessary to operate the device strictly in accordance with the instructions, and periodically carry out preventive examinations by a specialist.

Repair of the control board

If the main chip or its components are broken, contact the service center. To disassemble the TV and fix the hardware module, you should use professional equipment that is not available to the average user. It is possible that engineers will not repair the control board, but simply install a new part.

Backlight is off

Turn on the TV and look closely at the screen. Is the image completely missing? Perhaps there is a picture, but very dim, dark or blurry? Try shining a regular flashlight on the screen. If the image appears, then the Philips TV backlight is not working. This symptom indicates a breakdown of the power chip, inverter. The LED backlight burns out much less often. Sometimes only some diodes do not work, for example, located in the corners.

Inverter. a component of the power board, which is supplied with a voltage of about 1000 V (this component ensures the correct operation of the screen backlight).

It is strictly forbidden to try to change or repair the inverter on your own. Contact the professionals. They determine the cause of the malfunction of the Philips TV, and then change the inverter or backlight.

Power indicator is on

If the indicator is on, it means that voltage is applied to the microcircuit. Try turning on the TV using the remote control. No reaction? Press the “Power” button, it is located on the front panel, just below the screen.

Oftentimes, the reason for the power light on and the Philips TV does not turn on is a malfunction of the remote control. Such damage can be eliminated without special equipment and at home:

  • Open the back cover that contains the batteries and replace them.
  • Check the contacts in the battery compartment; oxidation may have occurred. Try cleaning the contacts by dampening cotton wool with alcohol.
  • Push all the buttons, they may sink, stick. Disassemble the remote control, clean the inside with cotton wool soaked in alcohol.
  • If moisture gets on the main chip of the remote controller, wipe off the remaining liquid.

In some situations, the remote control cannot be repaired, so it must be replaced.

If there is no response to the remote control or buttons on the front panel, and the power indicator is still on, the problem is solved by one of the following methods.

Activation of the protection system

Voltage drops activate the equipment protection system. The TV will not respond to commands until the power outages disappear. If the problem is with the activation of the protection system, turn off the device for about 15 minutes. Then try turning it on. Buy a voltage regulator to avoid these problems. As a result, you will insure the equipment against expensive repairs.

Why my Philips TV won’t turn on. possible causes

The equipment has a certain service life. Once it comes to an end, users run into problems. However, there are also unforeseen breakdowns, but they can be eliminated under warranty, if, of course, it is still valid.

What if my Philips TV won’t turn on? Do not rush to contact the service center, first you need to determine the cause of the malfunction. It is possible that you will be able to solve the problem yourself, saving on maintenance.

Let’s consider the main causes of the malfunction. It is important to determine in a timely manner, after which a breakdown occurred. Based on this information, a follow-up plan is drawn up.

Power indicator is off

When the light is off and the TV stops turning on, you need to check if voltage is supplied to the microcircuit. In some situations, the failure can be fixed very easily. Before contacting the staff of the service center, you need to check some factors.

Start by checking the mains power. Take an indicator screwdriver or plug a working device into the socket to check if there is voltage. You can also use a surge protector, voltage stabilizer. It is possible that the very socket to which the TV is connected is faulty.

It is possible that the TV does not turn on due to the fact that the power button is deactivated. Almost all Philips TV models have a button next to the LED on the front panel that allows you to turn off the screen. Try to click on it, maybe the image will appear.

The third reason is that the device went into sleep mode. To exit power saving mode, press the AV / TV button on the remote control.

If the above methods did not help and the LCD TV problem persists, contact the service center. The power light may be off due to a broken system board component. In this case, complete diagnostics with disassembly of the device is required.

Switching to standby mode

If the power indicator is on or flashing and the solutions above do not work, then the TV has entered standby mode. The malfunction occurs when the TV is connected to a computer, laptop and is used as a screen. Just move your mouse or press any button on your keyboard, the image will appear. An alternative way is to disconnect the TV from the computer and select a different signal source.

Malfunctioning processor or control

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

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

Pay attention to our other articles:

  • Do-it-yourself TV repair: LCD / LCD, plasma and kinescope. Schemes, videos and secrets of repair.
  • Do-it-yourself TV remote control repair. And also a video on how to fix the remote control buttons.

The indicator is on continuously

If the LED is on, this indicates that power is being supplied to the control unit. If the TV does not respond to signals from the remote control in any way, the first thing to do is 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 the case, the following actions should be taken:

  • Check the health of the batteries and contacts for oxidation.
  • Make sure that the emitter is intact and that the remote control buttons are not sticking.
  • If possible, disassemble and clean the remote control inside from dust.
  • If the remote control was flooded 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.

Indicator flashes

If the indicator flashes, then the TV itself diagnoses the type of problem. Usually the red light will flash 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 faults and their indication are indicated. And, already based on this, take the necessary actions.

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

You need to take 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. Basically, the TV is working. It’s just that the image is not fed to it.

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. over, in a large number of cases, the problem is caused by rather trivial reasons, including:

  • There is no power in the electrical outlet. The circuit breaker in the dashboard may turn off, or the outlet may be faulty. It is checked using a conventional indicator screwdriver or a tester. If there is no power supply, 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 the problem in the outlet or wiring yourself or with the help of an electrician.
  • Malfunction of the extension cord (if connected through it). When a direct connection to the outlet ensures the normal operation of the TV, but there is no power through the extension cord, it is in it. If it is a surge protector, you need to check the power button and fuse. In any case, a working device is required to fix the problem.
  • The “Network” button on the TV is turned off. On almost all models of modern TVs, when the “Network” button is disabled (it can be located on 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 is not used, for example, AV, PC or Receiver, the screen dims and can enter “sleep mode”. You need to select the TV function again and the picture will return.
  • Malfunction of any part. It can be a microcircuit or a capacitor, or perhaps a power supply or control system (for example, a button has broken). It is better to entrust the testing of the performance of various components of the TV and the implementation of the necessary repairs to the specialists of the corresponding service center.
  • Blown fuse. For CRT 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.

Common causes of malfunction

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

  • LED indicator blinks but TV does not turn on.
  • The indicator lights up 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 from the remote control.
  • TV clicks, hums, makes strange sounds, but does not turn on.

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

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

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

The most common causes of clicks on TVs are:

  • Interlocking system actuation. In the event of some types of malfunctions (power supply unit or other units), the protective function is activated. It is designed to avoid more serious damage in the event of a malfunction. It is the blocker that emits characteristic clicks when the TV tries to turn on.
  • Heating and cooling of the plastic parts of the case. So, even a working TV can click.
  • Giving a signal about an activated (not used for a long time) operating mode for the selected source. At the same time, TVs can beep or whistle.
  • Excessive load on the power supply. The cause could be a transformer, microcircuit, or transistors. In this case, the TV does not turn on at all. A qualified master is indispensable here.

Why the TV won’t turn on and what to do?

Like any technique, it is common for a TV 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. In this case, 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.?

Protection triggered

In this case, the TV may try to start, but after a few seconds the screen goes out, or it does not turn on at all. The main reason for this problem in most cases is power outages in the home network. It can be voltage drops or power outages and turns on when the TV is 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 a 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 turning off the light. If the voltage problem is constant, you will have to use a stabilizer, an uninterruptible power supply, or at least a surge protector. And when leaving home, it is better to completely turn off the TV.

DIY TV repair Mystery

Mystery TVs belong to the category of inexpensive modern household appliances. However, even they can sometimes fail. But not in all cases when the device stops turning on or the sound disappears on it, you must immediately contact a specialist. In this article, we will look at how you can fix such problems yourself.

The most common problem faced by the owners of TVs of this brand is that the device simply does not turn on, most often it does not start from the remote control. Although in some situations, no manipulation helps. In this case, certain indicators are lit on the TV itself. Let’s consider how you can solve the problem in each specific case.

Red indicator is on

If the light is not constantly on, but blinks, then there is probably a failure in the device software. In this case, you just need to reboot it. If the problem still persists, then a complete reinstallation of the software and possibly the purchase of a new power supply will be required.

If the red indicator is on constantly, and the TV does not turn on from the remote control, then you need to find on the TV panel itself (usually on the right side of the side) the on / off button and try to turn on the TV with it. For some models, the device starts up by pressing the “SOURCE” button. It is also necessary to make sure that the correct batteries are inserted into the remote control.

If there is no such button or the device does not turn on, it is necessary to disconnect it from the power supply and leave it alone for a few minutes. Then reconnect to the network and try to turn it on without using the remote control.

In some situations, none of the activation methods may help. This happens with strong voltage surges, as well as when it is too low in the network. Therefore, if the red indicator light is constantly on, it is necessary to check the voltage in the mains.

Why does not it turn on?

If it is constantly highlighted, this means that a failure in the matrix may have occurred or it has failed. In order to check this, it is necessary to disconnect the device from the mains and remove its back cover. Take a close look at all boards and the main control matrix. If it has dark unnatural stripes, then it needs to be replaced.

If the indication in blue is constantly blinking, and even at different intervals, you must carefully study the instructions for the device itself. Such a problem indicates some kind of internal error on the TV, which makes itself felt in the form of such a signal. The reason for its appearance and the ways to eliminate it should be written in the user manual.

If the indication changes its color from blue to red, this indicates several problems in the operation of the device that arose simultaneously. In this case, you should not try to repair the TV with your own hands. professional tools may be needed here.

In some cases, if the device itself overheats or problems with its kinescope, the screen may not light up, and the blue indicator will also light up constantly. This means that there is a problem with the broadcast of the image. In this case, when you try to switch channels, the sound will appear, but the image will not. In this case, only a professional master will be able to determine the exact cause of the breakdown.

And one more thing: if the TV screen was connected to the computer as a monitor, but the connection channel itself was selected incorrectly, then an indicator of any color may light up. Therefore, it is necessary to check both the correct synchronization of devices with each other, and the correctness of the selected connection channel.

How to get sound?

Sound skips in some situations. But even in this case, the repair of the Mystery TV can be done by hand.

  • If the sound is lost only on analog channels, you need to make sure that all the settings of the device itself are correctly set. You also need to check if the region of residence is one of those where channels with this type of broadcasting are already disconnected. In this situation, only installing a satellite receiver can help save the TV.
  • If the sound has disappeared altogether, but the image is still there, you must first check the level of the set volume on the device itself. And if necessary, you should add it.
  • If the TV turns on, but there is no sound or image, then there are problems in the microcircuits. Here it is also necessary to disconnect the device from the mains, remove its back cover and carefully inspect all boards and circuits for spots, stripes or damage. If everything is in order, then there was an error either when connecting the device or in its internal software. You need to restart your TV and reset all settings to factory defaults.

And one more thing: even if you yourself managed to establish the exact cause of the malfunction, but there is even the slightest doubt that the repair work can be performed safely and correctly on your own, you should contact the repair shop.

Only suitable tools and original spare parts must be used to carry out the work personally.

Other malfunctions

But sometimes other malfunctions may occur in the operation of a TV of this brand, which can also be solved by yourself.

  • When viewing, the image partially disappears or disappeared altogether. This means that the periscope has been interrupted. After diagnostics, it will become clear whether a repair or complete replacement of the device is required. Diagnostics should only be carried out in a repair shop.
  • The TV does not turn on at all and there is no indication. a problem with the power supply. It needs to be replaced.
  • The TV turns off spontaneously. Protection (against overheating and spontaneous combustion) can be triggered here, or the factory settings are set to turn off the device during continuous operation for more than 5 hours.

Before proceeding with the diagnostics of the TV boards and microcircuits, it is necessary to carry out its external inspection: make sure that the case is intact, that there is no burning smell, that all wires are connected correctly and that the backlight is working properly.

For more information on how to repair a Mystery TV with your own hands, you will learn from the following video.

Red color

If the user sees the red color of the LED, while the equipment does not want to start, this means that it is in standby mode, and you need to try to get it out of it.

In general, a lit indicator means that the power supply unit is normal. But you should still diagnose from this node. Namely, they measure the level and stability of the supply voltage.

There is a loop through which signals pass to the base modules, it is damaged and because of this the TV stops turning on. It is worth visually assessing the state of the power supply, check the level of filtration, see if there are swollen capacitors and, in which case, replace them.

It is the capacitors that most often cause the TV to malfunction, and the light on the case may continue to burn red. The power supply simply cannot give a command that would ensure the correct start of the equipment.

But not always the reason lies in the power supply. Another situation, also associated with problems in the voltage supply. the TV memory microcircuits “zeroed out”. To solve the problem, put the device into working mode, for which the system firmware is updated using the programmer. True, few people have it at home, so it’s easier to contact the service.

Another reason is that the system board or its circuits have shorted. There are converters and voltage stabilizers. For the processor to work correctly, current must be supplied to it. If not, the TV functions limitedly or does not react to anything at all.

Green color

Some models are blue. Again, this could be due to a variety of reasons. But you should start looking for a solution by studying the state of the main microcircuit: measuring its voltage, testing how the backlight works, a power activator.

It happens that in an attempt to switch the channel, a sound will be heard, while there is no picture on the screen (or it appears extremely slowly). The reason for the incorrect operation is searched for in the inverter or power supply unit, from which power is supplied to the display backlight. Also see if everything is in order with radiation sources.

The TV with a lit green indicator does not respond to the remote control because the main microcircuit does not receive a signal, therefore, it cannot transmit it further. It is possible that the problem is in the memory or inoperative inverter. To fix this, again, you need a programmer, which updates the firmware of the microcircuit responsible for memory.

All paths lead to the motherboard. it is she who blocks the signal transmission to the matrix controller. There may even be a sound, but not an image. To make sure that the problem lies in this node. diagnose the LCD matrix and T-con.

It is very difficult to fix hardware faults on your own, therefore, without proper experience, it is better to turn to TV masters.

If the indicator is on

When the TV does not turn on, while the indicator is constantly on, it means that electricity is supplied to the equipment, specifically to the control circuit. Further diagnosis includes simple steps.

Obviously, the TV does not respond to the remote control, so you can try to start it with the “Power” button located in the front or on the side (different for each model). Sometimes the problem lies in the remote.

  • contacts are oxidized;
  • the IR sensor is out of order;
  • does not receive power. the batteries are empty;
  • the microcircuit is dusty, covered with dirt;
  • some buttons do not work or they are “stuck”;
  • water got inside.

Repair of the remote control is not difficult, a person who has already dealt with the equipment can handle it. Of course, you can take it to a service center, but it’s cheaper to take a new one.

If the TV set does not respond to pressing “Power” on the case, this can be explained as follows. First, the built-in protection might have worked. It happens that the TV even turns on for a couple of seconds, but immediately its screen goes out. Elements of the protection system are triggered automatically due to voltage surges.

This often happens when the TV was in “sleep mode” and the electricity was cut off. To eliminate this malfunction, you need to disconnect the TV from the network for 5-10 minutes.

Sometimes the processor installed in the TV fails and the equipment stops turning on

During this time, he must “recover”. Then they insert the plug into the outlet and try to turn it on. If it worked. good, if not, it is highly likely that the reason is a short circuit of contacts or a burnt out hardware module.

A person is so arranged that he begins to look for solutions after the problem has appeared. Few foresee possible difficulties in advance. So, if voltage drops occur in an apartment or a country house or the lights are often turned off, it is better to get a UPS, a stabilizer or a good surge protector. This will help protect the hardware module of equipment from unpredictable phenomena.

Sometimes the processor installed in the TV fails and the equipment stops turning on. LED backlight (it is thanks to it that the screen produces bright, color-saturated images) is controlled by the Stand By cable and the Q211 transistor.

Sometimes a short appears in the block where they are located. Those who know how to use a multimeter, know where to get components for the TV and how to replace old ones with new ones. can do home repairs.

If there is no such knowledge, it is better not to risk it and call a TV technician to your home or hand over the equipment to a service center.

Electricity problems

Plasma display panels manufactured by LG or Samsung may not turn on not only due to technical problems. There might be a problem with the connecting cables, outlet, or antenna. You can try to connect the equipment to a different power source.

Electricity, namely voltage surges, can seriously damage your equipment. Because of this, fuses burn out, power supplies, hardware modules are overloaded. New TVs are equipped with so-called blockers that protect the main modules from burnout.

If the indicator is off

This already suggests that the TV is not receiving power. True, it happens that the diode is inactive, and the TV turns on at the same time. If so, it is burned out and it is enough to replace it.

  • problems with the outlet. So, it could break or the switch is turned off in the shield. To check if the socket is working, there are now special indicator screwdrivers;
  • the TV is connected to a faulty extension cable. The solution is replacement. Of course, you can try to fix it. Most often, the fuse and the power button fail;
  • the “Network” button is disabled. It is located on the TV cabinet, on the side, bottom or on the back wall. Until you turn it on, the TV set will not respond to the remote control or the “Power” button;
  • the wrong mode is selected. The user, due to inexperience, can choose “AV” or “HDMI” mode and will see a black screen in front of him. Required for the channels to be shown. digital TV;
  • the fuse is out of order. This is most often found in “pot-bellied” CRT models. The broken part is replaced with a new one.

If you have experience and professional equipment, you can repair the TV receiver with your own hands.

What to do if the TV does not turn on?

Any technique can fail prematurely. Televisions are no exception. over, it happens that both new and old TV panels, which have been working for years, fail. Only comprehensive diagnostics will help determine the cause. A common symptom is that the TV does not turn on, and the LED indicator on its body starts blinking. The article will talk about how to be in such situations, whether it is possible to fix the equipment and what is needed for this.

Technical difficulites

It can be anything from fuses to circuit boards and capacitors. It is difficult to visually assess their condition, so professionals use special equipment.

If the matter is in the matrix or the backlight, how to determine it:

  • the display shows stripes that were not there before;
  • there is sound, no picture;
  • broken pixels appeared;
  • the screen just glows black.

The matrix cannot be repaired. only replacement, but it is expensive.
