Samsung Shut Down And Won’T Turn On What To Do

When the help of the master is not required

Very often, the owners of TV sets panic and start calling 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 in equipment. It is required to check the behavior of the TV set for some symptoms.

Signal problems

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 until the end of the bad weather, and if the situation has not changed, then check the antenna (plug, cable, housing).

If your Samsung TV stops turning on

There can be many malfunctions with a Samsung television receiver, and it is not always necessary to have qualified help from a wizard to eliminate them. For example, if the Samsung TV does not turn on, then repairing it with your own hands in some cases is still possible.

Troubleshooting a TV

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 on your own without involving the service center specialists. The latter will have to pay a lot of money, while a small problem can be easily eliminated on your own.


Particular attention should be paid to the screen: even microcracks barely discernible by the eye can affect the quality of the picture. This can also include broken pixels. To diagnose the latter, the firmware provides special tests that detect dark or light points on the screen.

Periodic reboot

This is a typical platform failure. The problem is treated by updating the firmware to the current version or reinstalling it completely.

What to do if samsung galaxy phone won’t turn on

All Samsung phones can be restored even if they do not turn on. Just not all are the same.

If there is a “Home” button, then press it together with two others: “Power” and “Increase sound” (you need to hold down three at the same time).

If there is a “Bixby” button, then simultaneously you need to hold down instead of “Home” it. If there is no “Home” or “Bixby”, then together hold and hold “Power” and “Volume up”.

Release “Power” when “Samsung Galaxy.” appears, and hold the steel ones for another 10 seconds until the menu appears.

Then use the sound buttons to select “Wipe data / factory reset” and click on “Power”. Then, in the same way, select and confirm “Yes” or “Yes. Delete all user data”.

Finally, click on “Reboot system Now”. Samsung will reboot and start working like new, only all personal data will be erased.

The Samsung Galaxy turned off and does not turn on. Reasons

If your Samsung turned off and does not turn on, then damage to the operating system can lead to this, but this happens very rarely.

Much more often the reason is in the battery. Of course, the first thing you do is connect the charger and nothing happens.

You are confident in the outlet, in the cable, in the charger itself and in the contacts in the smartphone socket. Check these things out and make sure they are not the cause. It happens that the contacts on the battery are out of order, and this leads to the fact that the phone does not turn on.

In this situation, it can be very helpful to remove the battery and clean out the old contacts that connect to the battery.

Removing the battery will also reset the phone somewhat. The above method is only for smartphones with removable battery.

Also pay attention to the power button itself. It also does not last forever, although it does not break often, it does happen. If none of the above turned on the phone, then the problem may be inside the Samsung Galaxy phone. In its components.

The real reasons why the samsung smartphone turned off and does not turn on

If your phone is samsung note 2, mini, grand prime tablet tab 3, samsung galaxy, a5 2016, j3 2017, a3 2016, a7, c4 mini, j5, s8, s7, s6, a8, j1, tab 2, a6, c6 , s7 edge, c7, c8, j7, c3, s3, j2, a5 2017, s9, s4, tab 4, tab 10.1, s6 edge, j6, c5, s5, j1 2016, s4 mini, a5 2016, s4 mini, c9, gt n8000, c3, j2 prime, note 8, j5 prime, j7 2017, a3 2015, j8, tab 5, a8 plus, s9 plus does not turn on for no apparent reason, although the solution is not a fun process, very often the cause can be eliminated by yourself.

Defects are a common and well-known problem with smartphones, which we use almost without interruption and have become indispensable for us.

They are susceptible to numerous failures: it turns off and does not turn on, does not turn on and does not charge, turns off and spontaneously turns on, turns on and turns off immediately, after the update the screen does not turn on or constantly reboots. This is how both a smartphone and a button can behave.

What to do? Before heading to the service, try my options below, and whoever is friends with a soldering iron can even get inside. I also intend to describe such options. Go.

Your Samsung Galaxy smartphone doesn’t turn on yet. Let’s see what’s going on inside

Mobile devices, which work much like computers, have periodic defects that we often don’t notice. Worse when our phone won’t turn on and we don’t know how to fix it.

The answer to the question is very simple. All you need to do is go to the service, unfortunately, this is not always possible.

What can we do to avoid high post-warranty repair costs? I will advise you on how to diagnose your device.

Although the activity may seem very simple and obvious, but not everyone succeeds, and the first thing to do is to disconnect the battery.

Removing the battery and cleaning the contacts (connecting to the battery) on the phone can help.

Very often the smartphone has rusty contacts. Of course, many Samsung phones today have a non-removable battery. Then skip this step.

Removing the battery allows you to reset the phone. Second step. Viewing the charging connector.

It is worth looking into the connector with a flashlight to see if your plug is damaged from charging.

In addition to checking the power outlet, remember that the battery can also be the reason the phone won’t turn on.

The next step is to connect your phone to your computer by connecting a USB cable. If a window or “Install Driver / Software” appears on the computer, the Charge Controller may be damaged.

What to do? This is a little more complicated. In phones, it is often soldered to the motherboard, but there are also models in which it is a separate module.

You can try to replace the connector yourself, but if you are worried that repairing your smartphone will be overwhelming, then it is better to leave this business right away.

You can also see, for example, if the contacts have slipped off the display. This happens most often (although very rare) when the phone is dropped.

Removing the cover will allow you to check for damage. If the connector on the display is connected correctly, then you need to look for the problem somewhere else.

One of the common malfunctions in our device is when the phone vibrates in our hands after pressing the “Power” button, but the screen does not turn on.

Even then, you can determine that the defect is on the side of the display, and not on the charging connector or other components.

Worst of all, if the motherboard is damaged. This is the heart of the phone and does not bode well.

Even the service does not undertake its repair. Based on the profitability of the repair. If none of the above suggestions work, then the motherboard malfunction is almost certainly.

The repair costs in this case may be greater than replacing the display. Also, you should remember that there are data recovery companies in the event of damage to the motherboard. Success.

Types of faults

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

  • Indicator flashes red.
  • TV clicks, hums, hisses or whistles.
  • The indicator does not work at all.
  • The TV does not turn on, the lamp is on.

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

The indicator is off and the TV does not turn on

If the indicator is off, and the TV itself does not show signs of life, then there is often a problem. In a broken power supply or power outage. If the light bulb just burned out, then the device would work without any problems. Before you panic and contact your master, you can try to find out the reason yourself and eliminate it.

You should not immediately call expensive specialists if the Samsung TV does not turn on. Is the light on? Not? Read the tips below.

What to do first?

First you need to inspect the equipment. The manual describes solutions to some basic and minor breakdowns. For example, the problem of a non-switched TV may well be that the power button was incorrectly connected or selected, the power button was accidentally pressed or broken. In addition, it cannot be excluded that the power supply could burn out.

Before looking for solutions to fix problems, if the TV does not turn on, the light does not light up, it is necessary to determine what type of device you purchased. There are liquid crystal, plasma and picture tubes. In case of minor malfunctions, in principle, there will not be much difference in the repair, the only difference is in the “design” of the internal design.

Main breakdown indicators

Before you start troubleshooting, you must try to turn on the TV again. It is possible that the problem is in the power button, which for some reason has stopped working stably. The indicator can either be on or not, so you should also pay attention to it. In the first case, the problem is definitely not in nutrition.

Often consumers face such a problem: the Toshiba TV does not turn on, the light is on, there is no damage. So what’s the problem? We will understand further in the article. It is necessary to pay attention to the fact that it does not matter from which manufacturer the broken TV is: the solution to the problem will be the same. However, consumers who preferred Toshiba, Samsung, LG, Philips, unfortunately, encounter such malfunctions quite often.

The most common breakdowns

One of the common problems is a breakdown in the outlet or lack of electricity. Here it is necessary to look for a solution to the malfunction in the shield or in the network connector. Sometimes the reason is a complete lack of electricity. As a rule, in this case, the whole house is de-energized. You can check what is with the outlet using a special screwdriver or a tester. If there is no power supply, then it is necessary to proceed to the inspection of the machine. To ensure the best test result, the stopper must be clicked several times. If it does not help, then you should call an electrician.

If the TV is a CRT, then a blown fuse can be a common cause of breakdown. It is because of him that food stops being supplied. In the event that a part in the device is located in an easily accessible place, then you can replace it yourself, without extra costs for a specialist.

Philips TV does not turn on. Is the light on? If not, then there is a possibility that the consumer has chosen the wrong active mode. Many modern devices have special functions that allow it to enter a “sleeping” state. In this case, the TV reacts to the remote control. Just go to the menu and select the “TV” mode.

If the TV is connected via an extension cable, then it is worth checking its performance. In the case when the device is turned on during direct operation with an outlet, the problem lies precisely in the “intermediary”. It is quite obvious how this malfunction is solved. With a new or repaired extension cord.

The TV may not turn on if some parts are broken. We are talking about both microcircuits or capacitors, and about the power supply, buttons. In this case, it is best not to try to fix the problem yourself, because wrong actions can lead to big problems.

The most common reasons for this behavior of technology

  • Heat either on the cabinet or inside the TV. The most common problem for plastic items. In this situation, the failure to turn on the device, the lack of glow of the indicator and clicks will be typical for a working model. To fix the problem, it is enough to let the equipment rest for at least an hour.
  • The TV does not turn on, the light does not light up. Such nuances are characteristic of the triggered protection of the device. As a rule, if the power supply or other main parts breaks, the TV switches to a special mode. This avoids the most serious problem resulting from a minor malfunction. In this case, the device is unlikely to show signs of life. To fix the problem and return to operating mode, the major problem must be repaired.
  • Tvs will whistle and no indicator will light if too much load is applied to the power supply. You can fix the problem by replacing the transformer, microcircuit or transistor, as a rule, it is they who cause such a problem.

Technical problems

The source of trouble can also lie in the breakdown of the remote control (RC). Press the power button. If the indicator blinks, then there is no doubt that the remote control is working properly. If the indicator does not blink and does not react at all, it is worth checking your remote control. It may be sufficient to simply replace the remote control batteries. If there is an identical remote control nearby, you can check that too. If the TV still does not turn on with the remote, try turning it on with the button on the dashboard.

Sometimes, in the event of a breakdown, the speaker emits characteristic sound signals. Beeps, clicks, etc. If the speaker beeps when you press a button on the remote control, then the remote control is working properly, and the problem is different. Sometimes you may come across a modern LCD TV, which beeps when the mode is incorrectly selected and there is no connection with the player or set-top box.

If the image does not turn on even with the button on the dashboard, most likely the problems are inside the device. Modern LCD devices are distinguished by very complex technologies, and it is undesirable to try to fix them on your own. Listen. If something clicks in the back of the case, it could be a built-in blocking module. Very often it is he who becomes the cause of all problems. This module always clicks when activated, and if you hear such a click, you will have to call a specialist.

In the case of old CRTs, the “root of evil” was usually hidden in the fuse, and if you had certain skills, you could replace it yourself. But modern LCD products are created using a completely different technology, therefore, in the absence of special knowledge and skills, you will have to contact the specialists of the service center. We are talking about a fairly expensive sample of household appliances, and it is not worth risking such big money.

Connection problems

If you have purchased a new TV and it does not turn on from the first minutes of being in your home, the source of the problem should not be found in the device itself. The likelihood of defectiveness is very low, as all reputable manufacturers carefully check all their equipment before sending it to distributors. Most likely, the matter is in a wrong connection, a malfunction of the remote control or an error in control.

Read the instructions carefully and try again. For example, the problem might be with the power button, which might be disabled. If the power indicator is on and does not blink, then everything is in order with the power supply. If the light shows no signs of life, the problem might be with the power button or wiring. Carefully examine the cord and outlet, you can also check the voltage with a screwdriver, which has a built-in indicator. If the light blinks intermittently, it is possible that the contacts are moving away. In some cases, the indicator blinks when the light bulb is out of order. You can temporarily ignore such a problem. If no problem is found and the TV still won’t turn on, the problem is different.

What to do if the TV won’t turn on

Since television became widely available for every family, it is difficult to name a more popular way of spending family leisure time (and even the Internet cannot change this). But what if suddenly the TV stopped turning on? The first, and most important, advice is to not panic. If your brand new LCD TV or an equally expensive plasma version does not turn on for some reason, this does not mean that you need to call specialists. Nowadays, there are different repair teams, and you can rest assured that unscrupulous representatives of this profession will certainly take money from you even if the equipment was absolutely serviceable.

Therefore, you must first conduct an initial inspection on your own. Most malfunctions can be dealt with without much skill, using instructions from experienced people. It is possible that the problem lies in such trifles as an incorrectly selected mode, an accidentally pressed button, or problems with electrical wiring. To begin with, it is worth clarifying that the approach to different types of TVs is slightly different. The most common are:

  • Liquid crystal (LCD);
  • Plasma;
  • Picture tube.

But since you do not need to carry out direct repair of equipment, the difference will be insignificant. And the tips you can use to fix your LCD TV are also good for other technologies.

Incorrectly selected mode

If the TV does not turn on but the indicator is on, power problems can be avoided. The problem may be with the wrong mode. Every modern LCD TV is equipped with a variety of modes:

  • Duty;
  • DVD;
  • Game console.

And many others. Read the instructions and study each mode carefully. It is possible that your TV is in standby (sleep) mode. It is quite easy to determine this. The screen goes out in this state, and the indicator glows red or green.

Then check the rest of the modes. Some LCD models have a dedicated button to determine the current status. If you have selected the DVD player or game console mode, you will see only a blank screen and a lighted indicator. Check the jacks into which the plugs of the set-top box or player are inserted. If the mode is selected and the devices are not connected, the screen will automatically go out.

Recommendations for those who know how to hold a soldering iron in their hands

Among the reasons why the TV stops turning on, employees of specialized service centers call breakdowns of almost all main blocks. Pulse power supplies, photodetector modules, motherboards (Main Board or SSB) and backlight control inverters. They also note that the lion’s share of faults of this kind are due to faults in power supplies. For this reason, the first thing that needs to be done after the initial diagnostics (checking the voltage in the outlet, “ringing” the cord and replacing the mains fuse) is to examine the TV’s power supply according to the following scheme:

  1. Conduct a visual inspection for microcracks, chips and cold soldering, and then correct any deficiencies found.
  2. Replace any swollen capacitors identified during visual inspection.
  3. If, as a result of the examination, burnt or damaged resistors were found, then it is necessary to carefully check the circuits in which they are installed. In the case when voltage dividers were built on these elements, the health of the transistors, diodes and other semiconductor devices located next to them should be checked.

Most likely, fixing the breakdowns revealed during the initial inspection will be enough to make the TV work again. If the miracle did not happen, then further diagnostics are carried out by inspecting the fuse. Its repeated burnout may indicate a breakdown of power transistors or rectifier bridge diodes. In addition, the semiconductors on which the PWM chip is strapped should be carefully checked. The microcircuit itself is checked by replacing it with a new or known working part.

The TV power supply is easy to detect. It is indicated by the presence of winding units (transformers, chokes) and high-capacity capacitors

Modern LCD and plasma TVs, in addition to the main power supply, also have an additional standby UPS. This module is constantly under voltage, since it powers the circuits responsible for turning on the device from the remote control. The output of the additional power supply unit must have a low-voltage voltage, which is necessary to power the IR receiver and to maintain the processor in sleep mode. Often, after many years of operation, the capacitors of the network module dry up, lose their capacity, “go into a break”, or even begin to work in the diode mode. Of course, after the storage elements fail, the voltage conversion process becomes problematic, and starting the TV is impossible. Before you start looking for replacement parts, you need to keep in mind that pulsed power supplies have a high-frequency mode of operation. Because capacitors filter high frequency pulses, parts with low series resistance (called ESR) should be selected. During operation, they will heat up less, which means that after repair the TV will last much longer.

Solution: Delete or Format

It is better to discard the defective card immediately, regardless of what is on it. A card packed to capacity should be formatted.

If you have installed a large SD card on your phone, and are going to fill it not only with important files, but also with various programs, read our instructions on how to install the application on a memory card.

Battery malfunction

On average, the phone battery is designed for 2.5 years of use. If your phone was purchased more than 3 years ago, the battery may have run out.

Fault at the memory card level

The phone may refuse to turn on due to the SD card, especially if it was taken by hand or at an unreliable point of sale. In this case, there is a high probability that there is a virus on the card that prevents the phone from turning on. On the other hand, a serviceable but overfilled card can also cause problems to the user.

Solution: service repair

If you are faced with such troubles, either the display itself is broken in the phone, or the reasons for the problems lie in the cable that connects the screen to the board. Of course, you can try to carry out the repair yourself, but without certain technical knowledge, this can lead to the final breakdown of the phone.

We recommend that you do not risk your mobile device and take the gadget to a service where specialists will help you fix the problem.

Method 3
