Samsung a50 screen does not go blank

The monitor screen goes blank quickly. What to do

Received a letter asking that the monitor screen goes off quickly. Verbatim:

Teach me what to do so that in my laptop the monitor does not go out so quickly when I read texts?

Of course, there are serious problems with monitors, and finding solutions to such problems can be quite serious business. So in some cases, even calling a specialist cannot be dispensed with.

But, also in many cases, the monitor screen quickly goes out simply due to the installed power settings.

Therefore, first of all, novice users just need to pay attention to these settings, which is what we will do in this article.

Let’s talk about Windows 7 first, and then about Windows XP, so choose where you need to deal with the monitor screen.

Power settings in Windows 7

So, you have the operating system Windows 7 and the monitor screen quickly goes blank, whether it is a laptop or a stationary computer.?!

We go to the Power supply section. To do this, simply right-click on the power icon on the Taskbar (as shown in the screenshot below) and select Power supply in the context menu that appears:

If you do not see the power icon on the taskbar, in this case, click on the small triangle icon (in the picture to the left of the power icon) with the left mouse button and find the power icon.

You can enter the power supply in another way.

Start menu. Control Panel:

Next, select System and Security:

So, whether we entered the Power supply section through the Taskbar or through the Start menu, now in the selected power plan we click on the link with its settings:

And already here we can configure the way we need:

How long does it take to dim the display (monitor) or turn it off so that it goes out completely, as well as when to put the computer into sleep mode and adjust the screen brightness.

over, for a laptop, this can also be configured separately: From battery or From mains.

And, of course, after changing the settings, you need to save them for them to take effect:

So, if your monitor (laptop) screen goes blank quickly enough, try here to increase the time in the appropriate parameters (when to dim and turn off the display).

Since we have “climbed” into these settings, then, perhaps, it will be interesting for someone to delve into the additional settings:

But, this does not apply to the topic raised, so I will leave it for independent development, especially since everything is quite intuitive there.

Power settings in Windows XP

You have Windows XP operating system on your computer or laptop and you notice that the monitor screen goes blank quickly?!

We go to the Start menu. Control Panel:

Further, at the very end of the large list, we find Power Supply. We go there:

First, we choose a suitable power management scheme (as shown in the picture below), since perhaps some of the proposed schemes may suit us in terms of parameters (or at least approximately it may be suitable).

And we configure the parameters as we need. In particular, if, for example, we believe that our laptop’s screen goes blank quickly, then in the Display off column we increase the time (after how long to turn off the display):

Do not forget to click on the Apply button and then on OK for the changes to take effect.

So, if we think that on our computer (laptop) the monitor screen goes out quickly enough, then first of all we go to the Power supply to adjust it there. And here it was shown how to do it in Windows 7 and Windows XP.

Display (screen) not working in Samsung phone

Remember, if the screen on your Samsung phone is not working, then it’s time to contact a service center. If the mobile body looks completely intact, there are no slightest cracks, there are no smudges on the display, then the reasons may be as follows:

Sometimes the display on a Samsung phone stops working due to the fact that the screen itself, that is, the matrix, is damaged. Most modern smartphones from Samsung (A-series: Galaxy A3, A5, A7; S-series: Galaxy S5, S6, S7, S8; also some J-series models) use amoled matrices, one of the disadvantages of which is fragility. If they are damaged, as a rule, outwardly there may be no signs, since small cracks are under the glass and they can only be viewed from a certain angle. The outer glass very often remains completely intact, the phone boots up, makes sounds when touched, you can even pick up the phone from memory when there is an incoming call, but there is no image or backlight, only the touch buttons at the bottom of the screen next to the home button are lit. Do not try to make repairs yourself: not only is it difficult, but you can also aggravate the breakdown by damaging the loop of the touch buttons, the back glass cover, etc. Remember, our service center will solve your problem in a matter of hours: we always have the right original parts. If even you have the slightest doubt, then do not risk it: immediately take the phone to the masters, because only they will carry out a high-quality replacement.

Often a black screen appears in a Samsung phone: if the microcircuit that is responsible for controlling the screen, or some components in its strapping fail. It is quite difficult to replace them with improvised tools.

In rare cases (one in a thousand), the display does not turn on in a Samsung phone due to the fact that it has recently “landed” on a hard surface and the connector has come off the main PCB. In our center, it can be done in the shortest possible time or even in the presence of the client.

Learn more about the reasons why the screen is not working on a Samsung phone

It has already been said above that the exact cause can be identified only with the help of diagnostics on the professional equipment of the service center. But, consider the main signs.

It is worth mentioning that under this breakdown, many smartphone owners often mean a non-working touchscreen, i.e. touch screen. Describing a breakdown as a non-working display, it means that the screen does not respond to touches. We are considering cases when it is the display that does not work, i.e. no picture.

So that you understand. Modern smartphones are made up of many small components that are connected to each other using loops. Not only the component itself can be damaged, but also microfractures on the plumes can appear. In the case of moisture penetration under the case, especially for sweet or viscous drinks, oxidation can occur, which also causes unpredictable consequences.

The reasons

  • Physical damage. This category of causes includes not only shocks and falls, but also the ingress of liquids. There is not always visible damage on the screen surface. A microcrack in the board or one of the connecting components is enough for the screen to stop working. The influence of liquids was discussed earlier.
  • The display stopped working after updating the firmware. There are cases when the phone turns into a brick and does not react completely, or there is an indication of inclusion (diodes are on or there is a vibration response), but the screen still does not turn on. Probably the firmware is not suitable, or there was a failure during the update process and the installation was incorrect. In this situation, you will have to reflash the smartphone again.
  • The screen stops working while using the smartphone. Those. you use your Samsung and at some point the screen goes blank. There is a high probability of failure of the proximity sensor, which is responsible for locking the screen during a call when you bring the phone to your ear.

We have listed all the reasons and cases of display failure in phones from Samsung and any other manufacturer. Most often, of course, the cause is physical injury.

Our advice: contact the service center. Trying to figure out the problem yourself, you can only harm and make the final repair more expensive.

Not everyone monitors their smartphone closely. Quite often, unforeseen situations arise due to the fact that the device does not turn on or the screen does not work on Samsung. This can happen for completely different reasons, ranging from ordinary mechanical damage to factory defects. Let’s take a look at the most common reasons why a smartphone stops functioning correctly.

Why the screen goes blank on Samsung

Remember, if the screen on your Samsung phone is not working, then it’s time to contact a service center. If the mobile body looks completely intact, there are no slightest cracks, there are no smudges on the display, then the reasons may be as follows:

Sometimes the display on a Samsung phone stops working due to the fact that the screen itself, that is, the matrix, is damaged. Most modern smartphones from Samsung (A-series: Galaxy A3, A5, A7; S-series: Galaxy S5, S6, S7, S8; also some J-series models) use amoled matrices, one of the disadvantages of which is fragility. If they are damaged, as a rule, outwardly there may be no signs, since small cracks are under the glass and they can only be viewed from a certain angle.

If even you have the slightest doubt, then do not risk it: immediately take the phone to the masters, because only they will carry out a high-quality replacement.

Operating system errors

If the device freezes and does not turn on after that, then it is highly likely that the main problem lies in the operating system. Android OS (this is especially true for older versions) is not famous for its stability, so sudden errors may occur regardless of the brand and model of the smartphone.

In such situations, not everything is unambiguous, because in most cases, when the screen does not turn on, and the problem arose after freezing, you just need to pull out the battery for a couple of minutes, after which, most likely, the device will start without problems. Unfortunately, it is not always possible to solve the problem in this way, because sometimes the phone does not start even after that, and some devices are equipped with a non-removable battery (use the reset button located on the smartphone body). Where to find it, read the instructions.

If all the tips that were given above could not help you, then you will have to reset the device settings to factory settings. Unfortunately, all your data will be deleted, but the good news is that the operating system will start functioning normally again. Follow the instructions below:

  • Hold down the Volume Up and Home keys.
  • Press the power button without releasing the pressed keys.
  • In “Recovery Mode” you can roll back to factory settings. This process is individual for each smartphone, so you should look for instructions on the Internet.

Now that you have learned what to do if the screen of a smartphone released by Samsung does not work, you can take stock. Do not disassemble the device yourself if you are not sure of the success of the actions. Entrust it to the professionals working in the service centers. Only they can correctly diagnose a breakdown and replace a failed module.

Discharged battery

Let’s first analyze commonplace problems due to which the screen may stop working. Let’s start with the difficulties that can be associated with the battery. Most often, the battery simply does not receive the proper amount of energy from the charger. On Samsung, this can happen as a result of a faulty charger that stops working properly due to a burnout of the microcircuit inside the power supply.

Such cases are not uncommon and happen all the time, as a result of strong voltage fluctuations. With a significant increase in the input voltage, the board burns out. It’s good if the charger suffers, and not the device itself.

It is also worth mentioning that the battery can fail, but this rarely happens on devices from this company. This problem can be solved by simply replacing the battery with a new one. You can do it yourself, just choose the right battery.

Screen damage

Service centers often receive questions about what to do if the screen does not work after the phone has been dropped. In fact, if the reason really lies in the fall, then you will definitely not be able to solve this problem on your own. The phone can only be repaired by contacting the service center.

It is worth noting that when the device falls, several damage options are possible:

  • Damage to the display. Such situations can be solved only in one way. by replacing the display, but it is almost impossible to do this on your own. It is best to take the phone, the screen of which is off, to a Samsung service center, where specialists will replace it with the original one.
  • Damage to the screen control chip. If the screen of a device from Samsung does not turn on, this does not mean that the display is to blame for everything. It is not uncommon for people to replace the screen, but the problem is still not solved. Replacing the microcircuit is quite cheap, which allows you to solve the problem as quickly and efficiently as possible. It is not recommended to do this on your own, as you need specialized equipment for re-soldering the boards.
  • Damage to the connection of the connector to the printed circuit board. This situation is as simple as possible. To solve it, you only need to disassemble the smartphone, the screen of which has gone out, and insert the detached part in its place. 90% that this method will help your device.

It is worth mentioning that there are other rare problems as well. which can only be identified at service centers. Contact the experts if you have a screen on your Samsung phone. Samsung smartphones do not fail as often as they say.

What to do if the backlight of the screen does not work correctly on a smartphone or tablet, or the display does not turn off when it should be. Or, the smartphone screen goes blank when called and does not turn on. What to set up and how to fix?

Many users face a problem when an Android phone or tablet starts to act up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

Quick fix for Samsung Galaxy A50 that’s stuck on Black Screen of Death

For example, the device has problems with the screen backlight or its on / off functions, etc. do not work correctly. This may be due to:

1st: Software failure. i.e. the problem is a software failure

2nd: Hardware failure. i.e. the problem lies in the “hardware” (that is, it requires replacement or restoration of spare parts for the gadget)

However, do not rush to get upset. in 90% of cases with problems with the operation of the power supply adjustment system, adjusting the backlight, turning on / off the display of a smartphone or tablet based on Android, a software glitch is to blame, which you can easily fix on your own.

Quite simple. go to “settings”, find “backup and reset” there, in which you select a full reset with the deletion of all data. Be careful, the use of this method is often effective, but it entails the deletion of all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone or tablet. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.

It is based on solving problems with the screen of phones and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all, it controls system functions, corrects, and fixes all possible settings and synchronization errors. A small, easy-to-use, free utility for devices based on Android Multi Cleaner. You can download the application from Google Play and see its additional options in the description HERE. After installing the application, all that remains is to launch it. Further, from you, in principle, nothing else is required. The application will completely take over the control of the device’s functions. (By the way, among other things, the gadget will start charging 20% ​​faster, and its performance will also significantly increase, which will affect the loading and operation speed of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)

  • In addition, it is worth cleaning the system with NORMAL antivirus. Best of all, Kaspersky Anti-Virus copes with this task, which can be downloaded HERE. Unlike the “multi-cleaner”, the software of “Kaspersky Lab” is paid, therefore, if you do not have the opportunity to install such protection, you can skip this step

Changing the software of the device, or, as it is also called “flashing”. This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer of your device, download the utilities and the firmware itself necessary for the firmware, and then reinstall it on your gadget.

If none of the methods brought results, unfortunately, you will have to contact the Service Center to repair your tablet or smartphone.

samsung, screen, does, blank

Some users cannot find the option to completely disable protection, while others have problems using it.

It turns out that even when we find this option, the following message disconnecting is prohibited may appear, but there is a solution.

How to disable fingerprint on Samsung a50

To do this, enter the lock area (as I wrote above), only now you need to enter a registered fingerprint.

Then move the slider to the right opposite the Fingerprint line to the left so that it becomes gray (inactive).

How to disable protection on Samsung a50. PIN or password

Under the usual blocking, it is customary to understand the key (figure), since it is used for protection most often.

The first thing you must remember is that what you put, for example, the drawing, otherwise it will be more difficult to turn off (I already described how to proceed then).

Remember? Excellent. Then we break into the settings (gear icon), click on the line “Lock screen”.

Now in the first line “Lock Type” notice in blue the one you have installed.

For example, I have set a PIN-code, but you can have a picture or a password. In any case, click on this section. You will be prompted to enter twice what you put in the code or password. I have a pincode.

After that, at the very bottom, select “No”. That’s it, your Samsung a50 won’t bother you anymore.

What to do if you can’t turn off protection on your Samsung Galaxy a50 phone

Sometimes you will not be able to select the “No” option, because the information is displayed that this option was disabled by the admin.

What to do if the options for disabling protection are on a gray background with a message about its deactivation by the phone administrator?

This can happen due to encryption or data storage policy. You will not be able to set the No option in the passwords section and you will not be able to disable the lock screen using the programming options.

There is a solution to this. First of all, check if encryption is enabled when you enable it, blocking cannot be disabled.

The only solution is to turn off encryption. To do this, go to “Settings Advanced Settings Security”, find the encryption tab and select the option to decrypt the entire device.

If the error (more precisely inaccessibility) still appears, then another solution applies here.

You must enable another type of protection, deliberately lock the device by entering the wrong pattern, and then unlock it with a spare PIN.

Then all options will be unlocked and the specified error message will not appear. Thanks for visiting. Success.
