Sony Tv Does Not Turn On Indicator Is Off

There are times when there are no network faults, the indicator light is on, but not constantly, it blinks randomly. One of the reasons for such a problem is a malfunction of the remote control. It is necessary to check its work, visually inspect, to determine:

  • Mechanical damage to the case;
  • The state of the buttons (defects are not allowed);
  • The batteries are working, they may have run out, they need to be replaced.

If after checking the remote control the problem persists, you can try to turn on the receiver using the control panel located under the TV screen. If the connection fails, it means that the operating mode was configured incorrectly, or it has failed. The TV has various playback modes:

  • Standard;
  • Sleeping;
  • Connected to a personal computer;
  • Demonstrated through the player.

To return the TV to working condition, you can try changing its operating mode. Set the standard parameters (default), an image should appear on the screen.

Extraneous sounds when the indicator is off and the TV does not turn on

Some devices, in addition to light indicators, are equipped with sound sensors. They are an indicator of possible malfunctions. These sounds have several meanings. Normal include:

  • After pressing the power button on the remote control, a single click is heard;
  • Sometimes a small noise is heard due to heating of the plastic parts located on the device body.

When the instrument is factory set, it is possible that characteristic signals appear to indicate a problem. To decode the signal, you must carefully study the instructions. If a click is heard during power-on, and the TV first works, and then the image disappears, you can make an assumption about the damage to the microcircuit. A burnt-out part, after opening the lid, immediately catches the eye.

The TV does not turn on and the lamp does not light up

Modern household appliances have become much more reliable. It rarely breaks down, its reliability has increased. Manufacturers today produce high-tech equipment only of the highest quality. This allows the most famous companies to increase their sales market, to be the first in the ranking of the best companies.

The light is on continuously

If the lamp is lit with a bright continuous light, then the correct connection to the mains is made. The problem is related to the operation of the remote control. If it does not have mechanical damage, you can try to press harder on the buttons, especially when they fall. If the problem is solved, it is better to replace the remote control to ensure the normal operation of the device.

If the image does not appear even after using the keypad, the motherboard may be damaged. To check the entire electrical system, you must contact a specialized workshop.

The TV does not turn on: types of malfunctions

First of all, you need to determine the cause of the problem. Only after locating the source of the malfunction can you begin recovery operations. The main reasons for which the TV stopped turning on can be attributed to several options:

  • There is no electricity supply;
  • The device is not connected to the mains;
  • Damage to electrical wiring;
  • The remote control is broken;
  • The power supply does not work, replacement is required;
  • The operating mode is incorrectly adjusted;
  • Other technical problems (microcircuit flew), without the help of a specialist, repair is impossible.

The light is off

A light bulb on a TV has several functions. It shows the connection of the device to the network, the setting of the standby mode, and it is also a kind of signaling device of malfunctions in the operation of the device. Depending on the circumstances, the backlight mode will begin to change.

Most often, TV owners are faced with the problem of a complete lack of indicator backlighting. This problem is considered the simplest and the easiest to fix. If the indicator is inactive and there is no image on the screen, then the problem is related to the supply of electric current. To locate the fault location, several operations must be performed:

  • Make sure that the TV is connected to the mains;
  • Check the serviceability of the connection;
  • The plug of the TV cable must be firmly inserted into the outlet;
  • Sometimes knocks out plugs on the electrical panel;
  • If there is no electricity in the whole house, you will have to wait a little until the scheduled power supply occurs.

Why Philips TV does not turn on: what to look for a 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 TV mode.

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, the device simply did not turn on the first time. Don’t look for other reasons yet, just try restarting your device.

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

  • If the indicator does not turn on from the remote control, then try turning 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 connected.
  • 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. In case 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 TV models can have very different breakdowns. It is difficult to identify serious faults without proper experience. It is better to send it to a specialist for repair.

LG TV does not turn on: light is flashing

Like any home appliance, the TV is prone to malfunction. This can happen regardless of the life of the device and the manufacturer.

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.

Modern TVs and the following companies work according to this principle:

  • Samsung le37c530f1w;
  • Philips;
  • Rollsen;
  • Akira;
  • Toshiba (Toshiba);
  • Mystery (Mystery);
  • Bbk (Vvk, BBK) led2452fdtg, lem2488fdt, led;
  • Dns (DNS) m24dm8;
  • Sony (Sony) Erickson, Erisson, Bravia;
  • Dexp;
  • Hyundai (Hyundai, Hyundai;)
  • Helix (Helix);
  • Supra led;
  • Sharpe;
  • Knight;
  • Thomson;
  • Prima;
  • Jivisi;
  • Novex.

Overheating of internal parts or the case of a TV is a very common problem for modern appliances. In this case, the non-switching on of 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 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.

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

Before you start troubleshooting, you need to try turning 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 can either be on or off. In view of this, special attention should be paid to it.

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 entire 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 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 fault 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 the 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.

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, they produce liquid crystal, CRT, and plasma devices. 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.

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 response to pressing the buttons on the remote control, and a complete shutdown while the power supply is on. If plasma does not start immediately, try again.

Why the TV won’t turn on: 4 ways to fix the problem

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.

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 service staff, 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 exactly the outlet 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.

The 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 unclear? Try shining a regular flashlight on the screen. If an 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 is a component of the power supply board, which is supplied with a voltage of about 1000 V (this component ensures correct operation of the screen backlight).

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

Why my Philips TV won’t turn on possible reasons

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 to do if the Philips TV does not 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.

Switching to standby mode

If the power indicator is on or blinking and the solutions listed above do not help, 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 to disconnect the TV from the computer and select a different signal source.

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 on the front panel, just below the screen.

Often 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:

  1. Open the back cover, under which the batteries are located and change them.
  1. Check the contacts in the battery compartment; oxidation may have occurred. Try cleaning the contacts by dampening cotton wool with alcohol.
  2. Push all the buttons, they may fall, stick. Disassemble the remote control, clean the inside with cotton wool soaked in alcohol.
  3. If moisture gets on the main chip of the remote control, wipe off the remaining liquid.

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.

Control board repair

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.

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 that the TV is connected to the computer as a monitor. If a connected computer enters sleep mode or is disconnected, the LED will flash for a few seconds when turned on from the remote control. 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 the lack of power. If the light bulb just burned out, the TV would work normally, but without indication. Do not worry ahead of time and call the master. Initially, you must 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.
  • A defective extension cord (if connected 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, it is in it. If it is a power filter, 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 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. In this case, the TV 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. Select the TV function again and the image will return.
  • Malfunction of any part. It may 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.

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

Sometimes TV owners are faced with the fact that there are 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.

The most common causes of clicks on TVs are:

  • Interlocking system actuation. In the event of some types of malfunctions (power supply 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 (long not used) 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. You can’t do without a qualified master here.

Malfunction of 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.

  • Why does the TV turn on and off immediately: reasons and what to do?
  • DIY TV repair: LCD / LCD, plasma and kinescope. Schemes, and secrets of repair.
  • Do-it-yourself TV remote control repair. And also how to fix remote control buttons.

The indicator is on continuously

If the LED is on, this indicates that the control unit is receiving power. If the TV does not respond to signals from the remote control, 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, return it for repair or purchase a new one (preferably the original one will last longer).

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

Why the TV won’t turn on, and what action to take?

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. 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?

  1. Common causes of malfunction
  2. Indicator flashes
  3. The indicator is on continuously
  4. The indicator is off, the TV does not turn on
  5. Extraneous sounds when the TV is not working and there is no indication
  6. TV does not turn on, protection is activated ()

Checking if the cable is connected correctly

Many users understand that there is a problem when the LED constantly blinks in different colors, while the TV does not turn on. In this case, it is required to check the functionality of the main control blocks. If the indicator flashes randomly, without a specific sequence, then this also indicates damaged hardware units.

Non-working external nodes also lead to the fact that the TV screen is black. This is due to the power line of the device, which needs to be checked first. First you need to make sure that the correct cable connection is established between the external sources and the TV. This will let the user know if there is a connection problem. Therefore, it is necessary to disconnect all cables from the device, reinstall them tightly and reconnect them correctly to prevent loose contact. In addition, you need to make sure that the power cable and PSU are in good working order.

After completing this stage, they begin to check the functionality of the cables in order to understand whether they are working or showing a malfunction. Coaxial cable and HDMI should be in good condition. If the user finds a damaged cable, they need to take another one and check if the problem is solved. You can also try switching from one HDMI port to another to see if the port will work well. If he still does not respond, be sure to proceed to the next stage of diagnosis until a solution is found.

Checking web sources

It is performed to determine if the problem is with web sources. To do this, use the remote control by pressing the “Menu” button. If it is displayed on the screen, then the TV is in good condition and the problem is related to sites such as SAT Box, Cable Box, DVD Player, Amazon, Roku and others.

You should double check the above information source web pages to make sure they are working properly. To do this, it is recommended to turn them off and then turn them on again. This will solve the temporary connection error and black screen problem. If this does not help, you need to try connecting another web source to the TV, or the same source, but on a different TV. This will allow the user to find a likely solution to the failure.

Phillips TVs

Occasionally, the Philips Plasma TV screen may not light up, or a red and white flash may appear at the bottom of the TV screen, while in other cases, the Power LED may have a blinking error code or be steady on. Typically, these symptoms are common in Philips Plasma and are due to a failure in the power supply, main board, scan cards or plasma display. While some of these violations can be easily corrected through troubleshooting, others may need professional help.

The main reasons for the failure of TVs Philips, Thomson, Supra, Sony:

  1. Distorted image. It occurs due to the fact that the TV panel could fail. Usually, in this case, it is impossible to repair the panel yourself; you will need to replace it.
  2. Philips TV constantly returns to the settings menu, even after exiting the menu. In some cases, it could be a firmware bug. Therefore, in such a situation, all the user can do to fix it is to update the firmware using a USB drive.
  3. No sound. In many cases, the failure may be on a faulty SSB board. If so, your best bet is to replace the board. In this case, expert assistance is recommended. However, the user can replace the board himself if he has the necessary experience.
  4. The red power light on my Philips TV is flashing continuously. The most likely reasons that can cause this problem are: power supply, main board, scan driver.
  5. Horizontal red lines appear on the Philips TV. There can be several possible problems: a faulty buffer Y board, a logic board, or the main TV board. In such a case, the best technical means is to seek the help of an expert who could conduct the necessary testing of the nodes inside the device.
  6. Your Philips TV goes into standby when the power indicator flashes six times and then quickly three times. The error code on the TV indicates that the power supply or support and buffer Y boards are faulty. Therefore, to fix the problem, visually check if there are bad capacitors on the power board. If available, replacement of faulty components will be required. If after this the error still persists, the cause of the failure is a defective Y buffer board, in which it is necessary to measure the voltages at the outputs of the power supply. If the readings are correct, you will need to replace both the buffer and support boards.

In most cases, if the user does not know how to fix the problem with Philips plasma TVs on his own, then it is best to contact a specialist.

Correct TV setup

A custom TV may exhibit a black screen problem due to incorrect TV input settings. The voltage source may also not turn on the power. Therefore, the user needs to ensure that the inputs are set correctly. Using the remote control, press the Source button to see the available inputs and go to their settings.

Also, make sure that the component that can be used at the moment is selected for the TV input. Additionally, you can try switching to all TV inputs one at a time to make sure the component is properly connected to the correct input. Thus, the user can solve the black screen problem, for example, in the device in Samsung Smart TV.

Samsung Smart TV

Common problems with Samsung TVs include unable to turn on, signal detection, power-on delay, and no picture or sound. Other errors: fast shutdown, screen flickering, faded images and capacitor leakage, after which the board may burn.

A defective capacitor can cause a power-up failure or cause the TV to pop repeatedly at startup. A defective cable box or satellite can cause signal detection failure, resulting in a noticeable delay between changing channels or searching for an image on the screen. Defective capacitor on power supply makes Samsung TV take a long time to start up when turned on.

A defective fuse on the wrong input channel will make it impossible to display images when the unit is turned on. The TV cannot play sound when there is no power. If the TV has programming irregularities, it turns off for no reason. Firmware that is out of date can also cause this error.

A worn out jumper on the power supply causes the screen to flicker. Problems with LCD technology or poor TV settings can cause Samsung TVs to show deep blacks and discolored images.

Restoring your Smart TV to work should begin with diagnostics. It is extremely important to install the failed hardware section in time. There are times when at first the light diode shines green, but literally a couple of minutes later, the blinking becomes red. This code indicates a breakdown of internal components. Once connected, the processor sends a signal to the appropriate blocks. If at least one of them does not give an answer, the technological process is suspended. The TV will not light up until the damaged unit is repaired.

Diagnostics should be carried out with the involvement of specialists. It requires not only knowledge, but also the appropriate equipment. However, before contacting the service department, it is recommended to perform a simple check of the correct operation of external components, power lines, indication and communication.
