The Samsung text flashes on the phone and the phone does not turn on. Samsung smartphone does not turn on

The situation is understandable when the phone fell from a height and as a result the screen broke or cracked and stopped working. You need to urgently contact a professional service center. But what to do if there is no visible damage, but the device does not turn on? First of all, connect the charger and wait, if there is no help, then try turning on another charger. Frequent problems occur due to a broken cable or charging failure. If the procedures do not help, dial the service center number.

The main reasons why a Samsung phone does not work

The reasons why a smartphone fails are varied, but in 90% of cases the problems are directly influenced by the human factor. Specialists will organize high-quality diagnostics and clarify the situation. The client receives a notification by number about the condition of the equipment and learns the cost of the work. You can find out how much it costs to change a component by looking at the price list on the website. Please note that the price does not include accessories. Common reasons why the phone does not work:

screen malfunction, the device works, but there is no image;
water or moisture got inside;
does not respond to the power button due to its breakdown;
battery problem;
Android operating system crash.

It is worth turning the volume control up to full power and rebooting the device. If the indicator lights up during booting, characteristic sounds are played, but you see a black screen, then the smartphone is working, but there is a problem with the display. We will use a multimeter and an oscilloscope to check the condition of the video chip, display cable, and evaluate the matrix. If you need to replace a component, replace it as soon as possible. We will re-solder the faulty microcircuits using a special infrared station.

This happens due to power surges in the network, the device falling, or being flooded with liquid. Voltage drops can occur during charging, which will damage the power controller, motherboard, and transistors. The ingress of moisture causes instant oxidation of metal components, especially the contact paths of microcircuits. Because of this, the surface oxidizes, which leads to the cessation of current conductivity.

The button does not function due to loss of contact in the power circuit. We will disassemble the smartphone, solder a new button and connect it to the motherboard. A common problem is a mismatch between the charger and the phablet. As a result, the battery fails. The battery is negatively affected by voltage fluctuations and prolonged exposure to damp places.

The Android operating system powers the phone by providing access to components and resources. An unsuccessful update, buggy firmware, an abundance of running applications that load the processor and memory, viruses are the reason that the device does not turn on.

We recommend using a protective case for the case, an original charger for charging and keeping the smartphone away from moisture and direct exposure to sunlight. If a problem arises, the service center staff will offer a solution. A free courier is available to call your home. We will correct situations related to system failure; if it is impossible to repair it at home, we will take the equipment to a service center.

We work in the cities of Moscow, Yekaterinburg, St. Petersburg. Urgent repair service available. We service models: s2, s3, s4, s5, s6, s7, Ace, J, C, Note 3, Note 4, Xcover. If you have a Samsung Galaxy or another model, we can change any component in a couple of hours. The necessary parts are kept in the service warehouse. Call the call center operator 24 hours a day.

Smartphones from Samsung have established themselves in the market as reliable devices, characterized by stable operation and high-quality hardware components. Despite this, all sorts of breakdowns can occur with any equipment. In the article below we’ll look at why Samsung won’t turn on and what to do about it.

Reasons

There can be quite a lot of situations that led to the impossibility of turning on a mobile device, but they are all divided into two main categories:

Damage to the hardware. They involve damage to the internal contents of the smartphone. Most breakdowns cannot be repaired at home and will require contacting a service center or specialist.
Software problems. Consist of a failure of the device’s operating system. Having a personal computer at hand and following the instructions below, you can solve this type of problem yourself.

Troubleshooting hardware problems

The most common breakdowns of Samsung mobile phones are the following:

damage to the charger: power supply or cord;
battery wear or detachment of connecting contacts;
mechanical failure of the power button;
charge controller malfunction.

If you want to find out the cause of the malfunction, you should remember after what time the problem appeared. Perhaps the phone slipped out of your hands and hit the floor, or moisture got on the case. As a result, a crack could appear on the internal board or the supply elements could short-circuit. In this case, the device should be taken for repair and entrusted to a specially trained person to solve the problem, since it will be very difficult to cope with this kind of problem on your own.

If specific reasons why the Samsung does not turn on cannot be identified, then the first thing you should do is check the charger. Almost all modern phones are equipped with a special indicator, so when connecting the charger you need to pay attention to it. If the LED light is on, then everything is fine with the charger; if not, you should connect another one or replace one of the elements (cord or power adapter).
Next you need to inspect the battery itself. If the back cover is removable, then you must:

Gain access to the battery and make sure the contacts are well connected. If one of them does not touch the battery tightly, you can take a small screwdriver and slightly bend it towards the power element.
Make sure there are no swelling on the battery. Otherwise, you will need to replace the battery.
Take a multimeter and measure the voltage at the battery contacts. In a discharged state, this indicator should be equal to 3.7 V, in a charged state - 4.2 V. A significant deviation indicates a faulty battery and the need to replace it.

If you were unable to gain access to the battery or the inspection did not reveal any problems, you should make sure that the power button is working properly. To check, you must complete the following steps:

Download and install a program called ADB Run on your computer. This is a special utility that can be used to flash mobile devices, set superuser rights, etc.
Connect your smartphone to your PC using a USB cable and launch the program.
A window will open with a list of possible actions. At the bottom there is the “Input” line, where you should enter the number 4, corresponding to the “Reboot Device” command.
In the additional menu with reboot options, enter the number 1. The phone will restart.

Completing the described procedure will allow you to start your smartphone when the “Power” button is not working. The only thing that can prevent you from using this method is the “USB Debugging” mode disabled on the device.

Other hardware damage will be difficult to identify without certain knowledge regarding the operation and repair of mobile devices. Next, we will consider the options when a Samsung Galaxy phone does not turn on due to problems with the software.

Troubleshooting software glitches

Most software problems arise after changing the firmware version or trying to obtain root rights. The first step to fixing the problem is to reset to factory settings. The procedure is performed as follows:

You must press and hold the power, volume down and return to home screen keys. Release when the smartphone starts in Recovery Mode.
In the menu that opens, you need to go to the line “wipe data/factory reset” and start the operation.
Wait until formatting is complete, and then select the line called “reboot system now”.
The smartphone will reboot in normal mode.

Before performing the procedure, you should take into account the fact that all data stored on the phone will be completely and irrevocably destroyed.
If you cannot enter Recovery Mode, you will need a complete flashing. To understand what to do to install a new operating system on a Samsung phone, you need to follow the instructions:

Find it on the Internet, download and install a special program - Odin. Please note that for devices released before 2012, version 1.86 is suitable. For later smartphone models, you can use the latest software versions.
Visit the page at: sammobile.com/firmwares and download the firmware version specifically designed for this phone model. You should be extremely careful, otherwise even minor differences in the name can lead to downloading the wrong file, problems with installation and further use of the mobile device.
Connect your smartphone to your computer.
Press the Volume Down and Power keys at the same time to put the device into boot mode.
In the Odin program, click on the “AP” line. In the explorer window that opens, select the firmware file. Then press the “Start” button.

If your phone does not turn on, this can make any user nervous, but in any case, before taking the device to a service center, you can try to provide first aid to resuscitate the smartphone. Problems due to which the phone does not turn on can be either software, for example, a problem with the firmware due to an unsuccessful update, or hardware, for example, due to a failed battery.

Below we have tried to put together a lot of tips that will help you figure out why your phone won't turn on. If none of the tips helped you, please describe your problem in the comments.

The phone does not turn on after repair.

If you decide to disassemble the phone yourself, and after assembly it does not turn on, then the problem may be that you simply forgot to connect power to the motherboard of your device. You must disassemble it again and make sure that the power supply circuit from the battery to the motherboard is not broken and all cables are in place. If you have a multimeter, try checking the voltage on the battery, or after assembling the phone, try putting it on charge. Almost all phones notify you when charging starts, even if the device is turned off.

What to do if water gets into your smartphone

Let's look at the hardware reasons why the smartphone won't turn on.
One of the reasons may be falling into water. What to do if your phone falls into water? First, remove the battery, you need to do this as quickly as possible, then dry your smartphone with a hairdryer. Control the air; it should not be hot, otherwise the touch glass and some other components will simply begin to peel off. Then, without inserting the battery into the smartphone, put it in a warm place. It is worth noting that you do not have much chance of salvation and it may not be possible without losses. In particular, the buttons on the device may stop working. If you have dried your smartphone, but it does not turn on, it needs repair at a service center. The worst thing that can happen is replacing the system board, which, by the way, It costs as much as a smartphone itself.

The smartphone does not turn on after being completely discharged.

This problem is observed in some modern smartphones. In particular, Sony phones. Some Sony phones had such a feature that it was impossible to turn them on after being completely discharged if the phone was in this state for a long time. One thing helps - long-term charging of the battery with a current of 2A. And these are almost all chargers.

In any case, as I already wrote above, you need to put your smartphone on charge for several hours. Usually the problem goes away on its own. You can try a charger with a higher amperage, for example, 1.5 or 2 Amps.

Also try making your smartphone.

Check the battery. The phone may not turn on due to a faulty battery.

This is a must. If you have a removable battery and can install another one, do so. Sometimes, although not often, the problem that prevents your smartphone from turning on may be the battery. By the way, is your battery fully charged? Maybe this is the case?

With some phones, especially if the phone is several years old, the actual battery charge may not match what your phone shows. If your phone won't turn on, try charging it for a few hours. It is possible that the battery will charge and the phone will turn on.

The battery wears out very quickly. Many mobile phone manufacturers provide a one-year warranty on the device itself, and half a year on the battery. The reason for battery failure is quite simple - a very heavy load on it. We constantly charge our phone, and as you know, batteries lose their charge with each charge-discharge cycle. For example, standard lithium-ion batteries installed in our phones work properly under load for no more than two and a half years.

Check the charger.

If your smartphone is dead and it won’t turn on again, maybe it’s a charging issue? Try charging your device from your computer. If the phone shows no signs of life within half an hour, the problem is not with the charger. If the phone seems to be charging, but cannot charge, check the charger on another phone. It is quite possible that it will need to be replaced with a new one.

The phone does not turn on after being dropped. Mechanical damage.

Smartphone manufacturers like to say that their phones cannot be scratched, drowned or broken. Manufacturers give their phones Gorilla Glass screen protection, IP67 water resistance, shockproof casing, and so on. Despite all the phone protection measures taken by companies, it often happens that the phone does not turn on after being dropped. For example, on asphalt or falling into water. Unfortunately, all that can be done at home after a fall is to see if the battery, power cable or display cable has come loose, if there is a sound or vibration signal to turn it on.

It’s unlikely that you can do anything more with a dropped phone at home. To do this, you need to check the voltage on the battery and on the system board. If your phone is dropped and won’t turn on, and you don’t have the necessary tools at home, you will have to take the phone to a service center.

After the firmware the phone does not turn on.

One of the most common reasons why a phone may not turn on is due to an incorrectly installed firmware or update. After flashing or updating the phone does not turn on due to incorrect installation of files. In this case, you will need to flash the phone. For example, if your Samsung phone does not turn on, then you will need to download the firmware from the official Samsung website and the Odin flashing program. Using this program you can flash your phone. All settings and files on the internal memory will be deleted, but there is a chance that the phone will turn on.

If Lenovo phone won't turn on, then in this case you will need to enter Recovery mode by simultaneously holding down the power and volume up keys. In the Recovery menu you will need to select the wipe data/factory reset menu item, and then Yes - delete all user data. Unfortunately, different phones have different ways to access the Recovery menu. If you are sure that you installed the official firmware or an official update, then contact the manufacturer’s authorized service center, they will restore the firmware.

But we recommend you try perform a Hard Reset by resetting the phone to factory settings. Very often this helps if the phone does not turn on. Below we have selected key combinations for popular phones.

Samsung phone won't turn on: Press and hold the volume rocker up, the center menu button and the power button at the same time.

LG phone won't turn on: Press and hold the power button and volume down button at the same time, then select wipe data/factory reset.

Huawei phone won't turn on: Press and hold the Volume Up key and the Power button at the same time. You can try pressing the home button, volume up key and power button.

If your other phone does not turn on after flashing, write the exact model in the comments. We will try to help you.

The phone turns on and turns off immediately, what should I do?

It often happens that after updating or installing a program, your phone turns on and immediately turns off. Usually it looks like this: the phone turns on, the logo appears, the boot process takes place and the phone goes into an eternal reboot or turns off. There can be a lot of problems here, from the firmware to the battery. If you have a problem with your phone after flashing or updating the device, then roll back to the previous firmware or reset the settings. It will help.

Sometimes the phone turns off while the device is booting up. Consider your phone does not turn on and the advice from the previous paragraph will help you. You must perform a HARD RESET or flashing the device using a computer.

If you have not updated the firmware, then the whole issue may be the power button, which “sticks” and turns off the phone. Unfortunately, this happens very often, especially if the phone is in water. In almost all smartphones, the button is soldered to the motherboard and can be replaced.

If The phone turns off and turns off immediately after the complete download, when you see the desktop and icons, then try to remove the latest installed programs, if, of course, you have enough time for this.

The phone may turn off immediately due to the battery. Check the battery and system board cables. Even if a smartphone has a “non-removable” battery, removing it is not that difficult. In any case, if you are sure that the problem is not in the firmware, then you can most likely find out exactly the problem due to which the phone turns on and off immediately at a service center. Again, the problem is either in the firmware or in the power circuit.

These simple steps can help you provide first aid if your smartphone won't turn on. If none of these points suits you, take the device to the store if it is under warranty or to a phone repair service center if it is no longer under warranty.
