Help, master! The Samsung monitor automatically goes black when it is turned on! 15

If you are in the boot into the desktop or has entered the desktop, automatically but suddenly black screen phenomenon, try to reinstall the system first, prompt a point to reinstall the system is mainly to reinstall your C disk, if there is anything more important in the C disk, it is recommended that you back it up, if there is no black screen phenomenon after reinstalling the system, it means that this is just a system software problem, of course, if it will be after reinstallation, it cannot be ruled out that it is a hard disk problem on your host, including the motherboard, power supply, and your hard disk has bad sectors (hardware bad sectors mean that your hard disk has a problem, what is a hardware problem, you can check it) and other problems, then you need to go to the place where you bought the computer to repair the internal hardware problems of your host. If the display light is not on, it is a problem with the display, and it is recommended to repair it!

Is the indicator light on, if the indicator light two problems may have two kinds, the first makes the display problem, and the second is the graphics card problem.

If the indicator light doesn't light up, it's a problem with the display, maybe a power supply system.

If the display is in use, the screen is black, and the indicator light is also on, it is estimated that it is a problem with the display, it may be that there is a problem with the lamp, which is more troublesome, and there is a problem with the high-voltage board, which is easier to solve.

If there is no signal on the display, and the power is turned on, it is most likely that there is a problem with your graphics card and slot, especially in this kind of weather, it is rainy in the south, the humidity of the air is relatively large, and if the ground wire is not connected, the chassis shell is electrified. And the parts inside are prone to problems, so it is recommended to switch to the integrated graphics card to try it first!

The main factors that the mobile phone cannot be turned on are the battery, mobile phone software, and hardware that will cause the failure to turn on. Samsung mobile phones are generally recommended to carry out the following steps to troubleshoot and deal with: 1. Charge with wire for a period of time and try to turn it on.

2. Take out the SIM card and SD card at the same time, and then press the power button for more than 10 seconds to test whether it can be turned on. 3. If you can enter the boot interface, but your phone cannot enter the home page, please restart your phone to try. The steps are as follows:

Press and hold the power button and the down volume button at the same time for more than 7 seconds to restart the device. (Note: Some models require you to press and hold the power button for 8-10 seconds to restart the phone).

If it still can't be turned on normally, there may be a problem with the system program or hardware, and it is recommended to send the phone to the nearest service center for testing.

A large number of Samsung mobile phone systems crashed overnight: black screen, garbled characters, unlimited restarts.

Hello and welcome to the Samsung Digital Services platform.

There is a problem that needs to be eliminated for this kind of problem, that is, whether there is a problem with the software control in the system, it is very simple, you put this monitor on other hosts to connect, and see if the problem still exists.

If the problem is still there, then it needs to be repaired, no way, it should be the original of the display damaged.

Yes, there is a problem with the touchpad and backlit pad. Send it for repair!

I guess there is a problem with the touchpad, take it for repair.

1.Check that the monitor cable is securely and reliably plugged into the host interface, and then check that the contact between the graphics card and the motherboard's IO slot is good

2.If the computer starts normally on a different monitor, the original monitor may be damaged;

3.Check if the CPU fan is running;

4.You can remove all components except the CPU, graphics card, and memory sticks, and then power on the computer. If there is a fault in the memory, there should be an alarm sound. If there is no alarm sound, then turn on the CPU and re-detect. If the computer screen is still black, it is recommended to replace the motherboard

5.Whether the system has installed software and update patches, and if so, uninstall the update files

6.After installing the software on the computer, restarting the update causes a black screen, just wait for the update to complete

7.You can go into safe mode to repair your computer, if you can't get into safe mode, please reinstall the system.

Judgment must be made based on the situation of the display indicator after the black screen;

1. After the screen goes black, the indicator light of the display does not light up.

1. The power adjustment tube of the switching power supply part of the display is soldered at the base pole, or the resistance is soldered

This type of failure can generally be restarted immediately after a black screen;

2. The thermal stability of the power adjustment tube and the voltage regulator diode is poor

This type of failure generally cannot be restarted immediately after the black screen, and you need to wait for a certain cooldown time

2. The indicator flashes after the screen goes black.

Generally, there is a problem with the DC DC conversion circuit of the display, or there is a short circuit in the load

3. The indicator light is always on.

Indicates that the host signal has been received by the display, and the faulty part of the (display) is:

1. The high-voltage board and its power supply circuit;

2. The backlight tube is aging, or the pin is oxidized, rusted, and soldered

3. There is a problem with the AD driver board;

The simple way to distinguish the above items is: if you can see the "display" content after the black screen under strong light (or when squinting), the fault is Article 1, otherwise it is Article 3, and the landlord can judge by himself according to the actual situation.

It should be that there is a problem with the power supply high-voltage board, and it is generally about 50 80 to repair it.

It is very likely that it is a problem with the high-voltage board My Samsung monitor 943nw also had this kind of problem Next time I will never buy something from Samsung again.

First of all, take the display apart There are only two circuit boards in it The one with the coil is the high-voltage board See if the capacitor is bursting or the coil is burned black These faults should be easy to see If you don't want to repair it, go to ** to buy a high-voltage board Plus the freight is a total of more than 30 After buying the board, you can install it and you can get it This is how I got it The monitor is easier to repair than the computer.

Problems with the monitor. It shouldn't be much.

According to your description:

1.It may be due to the installation of third-party software that conflicts with the computer and destroys some functions. Since you can't see the machine, you can't accurately judge the specific problem.

Not found : boot may be due to the boot sequence setting of the boot item is incorrect, or the hard disk is faulty. It is recommended that you reinstall the genuine operating system, and adjust the hard disk to the first boot item after installation.

If none of the above methods can be solved, it is recommended that you take a test at your local service center.
