What to do if the monitor does not turn on

Often the reason for the malfunctions lies not in the display itself, but in the computer. Check each option and solve the problem on your own.

Before proceeding to further diagnosis, you need to make sure that the monitor receives food. This is indicated by the LED on the front panel, which should burn or blink one of the colors.

If the indicator does not shine, check the power buttons on the monitor and the extension cord: perhaps someone or you yourself accidentally pressed them during cleaning and did not notice.

If everything is in order there, then the reason may be in the cable. From the side of the fork, it is fixed in the outlet quite clearly and reliably, but in the monitor power connector it is simply inserted. Perhaps the wire shifted slightly in the nest and the contact was violated.

Try to insert it a little stronger into the connector and check the indicators. Charges can be with the cable itself. To exclude them, replace the wire to others, for example, from a computer power supply. they are suitable (unless this is a model with an external adapter).

Checking the monitor

If your monitor is working after steps in method 1, then the monitor may not display when turned on due to a faulty VGA cable. Try to replace the cable itself and inspect its chips, are they clogged with dust or whether the maples are bent.

What to do?

First of all, it is necessary to find out whether in the monitor is the matter. How to do it?

  • Earlier, when everything was in order, there was one short squeak when the computer is turned on? Is there now? No. you need to look for a problem in PC.
  • Previously, when downloading Windows, a welcome melody played? Is it playing now? No. a problem with a computer.
  • A good option is to connect the monitor to another computer (if you have a laptop or netbook, then it is almost guaranteed to an exit for the monitor). Or another monitor to this computer. In extreme cases, if you do not have other computers, taking into account the fact that the monitors are not very bulky now. contact your neighbor, try connecting to his computer.
  • If there is a short squeak, the sound of Windows loading is also working on another computer, you should look at the computer connectors on the back side and, if there is a connector for connecting the monitor on the motherboard (built.in video card), try to connect it there. If everything works in this configuration, look for a problem in the video card.

In general, these simple actions are enough, in order to find out if you really do not turn on the monitor. If it turned out that the breakdown is not at all in it, then you can contact the PC repair master or, if you are not afraid and have some experience to insert and remove boards from the computer, you can try to correct the problem yourself, which can be read in a separate instructions : What to do if the computer does not turn on.

Hello. Tell me what could be the matter, transporting the computer to a new place, I launch, it gives out 2 short and 6 long sounds. The monitor does not turn on. I did not find in the internet what this mistake means. I don’t know the BIOS version

Hello. Different values ​​are. Re-check that the monitor is well connected to the desired output (if there are outputs of an integrated video card and discrete), and also try to turn off the keyboard and mouse (these sounds can be due to problems with them or with their connection).

Thanks for the answer. In general, the problem was in the culer on the video card. He spun poorly, and sometimes he began to spin only from the push. I tried to lubricate YouTube rollers, but he came to an end) in general I decided to buy a new one

Hello. I have an old computer. After the voltage outbreak, he stopped working, took the service to the service. it turned on the day worked normally the next day turned on, but the black screen and asks to install or download the damaged wines 32 kr.Dll something like that. and in addition, the drive for some reason does not work. How to understand all this I will be grateful for your advice

Hello what exactly is written on the black screen? In general, according to the description, most of all, it is similar to the result of your actions, and not some kind of breakdown. And about the disco: how exactly does not work? It opens at least?

If possible, then do the following: take off the HDD, insert it into another computer as a second disk, put a jumper from behind on SLAVE, download the computer (main) as usual, if there is then from the installation disk (for your Windows, or from NTE), download the required file and copy it in a folder required by Windows, put the jumper in place, as you initially stood, put the railway in your computer, try to load (but carefully look from what contacts on the train you turned it off, for example, if you put it on the last settlecock, then then Do not boot, I don’t know why but by experience it is checked.

Hello, please tell me, if it turns on PC everything works only there is no signal and melody of views. What could it be?

According to the description, it seems that it does not turn on just: t.e. The fact that he makes noise fans and light bulbs burn does not mean that he turned on. Read more here: https: // Remontka.pro/Computer-ne-Vklyuchaetsya/

Hello, I faced such a problem by Disk Boot Failure. INSERT SISTEM DISK. I threw BIOS through the battery and now the monitor has stopped to tear down. Please tell me how to solve these two problems

Hello. And if you connect the monitor to the integrated video output? (if there is such an opportunity).

Hello. The problem is what. When the PC is launched, the monitor sometimes turns on (the standard launch of PC occurs). and sometimes it does not turn on. but the system unit is safely launched with all the signals of the bios. I should pull out the network fork of the monitor from the outlet and immediately turn on how the monitor begins to work, showing the desktop. t.to. The systematic manner had already started by this time. (probably something with the GTX 650 video card ? maybe there are any assumptions)

Hello. If you have Windows 10, 8.1 or 8 for starters, try turning off the quick start and check if the problem will be preserved. Disconnects like this: https: // remontka.pro/Fast-Startup-Windows-10/

Hello, I turn on the PC all the fans spin and there is no sound boot sound and the monitor writes that there is no signal. What could be the problem?

monitor, does, turn, first

Check the voltage on the BIOS battery for starters, 3 volts should be

Hello! Such a problem. the monitor does not turn on. The story is: changed thermal grease, after which the monitor stopped working. I took off the processor and saw that a couple of drops of thermal paste got on the process. deleted it, put it again and everything worked. Worked until the first shutdown. After which the monitor stopped turning on again. Again did not shoot the process, t.to. Already worked with him. I tried to connect to a built.in video card. it works. How to fix the problem.

Hello. But nothing more was done inside the case? Power cables did not turn off?

Not. When replacing, thermal paste took off only the cooler and that’s it.

The processor is noisy, the indicators are burning, the drive opens, but the monitor does not react in any way. Perhaps the problem is in the processor? What to do?

No Signal or No Display in Monitor || Computer turns on but no display

Hello! After pressing the power key, the PC begins to rustle slightly as usual, but the monitor does not turn on. Pressing the key off./VCL (power) on the monitor, on the monitor writes that there is no signal. At the same time, pressing on the system key and rebooting is without useful, zero reaction. You can disable PC only from the network.

It is possible not only from the network, but also a long retention of the power button (provided that everything is correctly connected there). 2. See the article: https: // remontka.pro/Computer-ne-Vklyuchaetsya/

I installed Windows 10 and the computer stopped turning on 1-2raz turned on and stopped showing the image at all, but the sound and the LEDs work. The monitor works 100%.

The monitor does not turn on due to problems with the settings

Problem. Incorrect monitor settings can become a real reason for its inoperability. For example, the user sets the screen resolution unreserved by the device or the update frequency. On some monitors, unsupported settings will be dropped automatically, on some this problem will become a real headache, as the device will refuse to turn on.

Decision. This problem is also solved by happiness. If you are incorrectly settled, you need to start the computer in safe mode and reset the monitor settings, or the restoration of the system. How to start a computer in safe mode on Windows 8, Windows 7 and XP we have already told.

After starting a safe mode, we move to the Start menu and set the “Restoration of the System”.

We launch the recovery process and follow all the instructions.

Make sure that the power voltage switch is installed correctly

If the input voltage for the power source does not correspond to the norm (depending on the country), PC turns on, but does not display the work on the display or keyboard.

When this switch is installed incorrectly, it is quite possible that the PC will not turn on at all. Therefore, the improper voltage of the power source may prevent the correct launch.

When the computer is turned on, the monitor does not work due to its own malfunction

The monitor may stop working for reasons beyond us. It can be a voltage jump, and fatigue of materials, or just a failure of any electronic component. This can explain why the monitor does not work when you turn on the computer. At home to fix a broken monitor is unlikely to work. Of course, if you are an employee of the service center with experience, you can cope with the monitor repair and with your own hands. But most people are ordinary users. Therefore, it remains only to correctly diagnose the problem and transfer the device to the service center.

It is logical that the screen can be considered the conditions when it is generally “silent”. That is, indicators do not burn and there is no image, and the monitor does not turn on either the first time or subsequent. To establish whether the monitor itself is to blame for this, in fact, in two ways: check the power cable and video. The whole check comes down to find a similar wire and test it on our suspect. If you are familiar with other methods of diagnosing and eliminating problems in monitors, you can share them in the Комментарии и мнения владельцев.

How to reset BIOS settings?

When there are two video cards (integrated and external) on a computer or laptop, problems with the monitor often arise due to incorrect bio settings. That, in the configurations, the device is automatically installed. The user needs to return the default parameters. There are two ways to do this.

The first method is the CLEAR CMOS function

  • After turning off the device from power supply, we find the Clear CMOS jumper on the motherboard (usually located near the battery, as it looks shown in the screenshot);
  • It is required to rearrange the jumper in a neighboring place;
  • Press the Power button, then insert the jumper into the starting position and turn on the PC;
  • After that, the password and settings will be dropped in the bios.
monitor, does, turn, first

If you have not found a jumper, we proceed to the next instruction.

The second option is to disconnect the battery

  • Turn off the computer and find the battery on the motherboard;
  • Pull it out of the bar and press the power button;
  • It remains to wait from 30 to 180 minutes;
  • Now the battery should be inserted back, connected to the computer to electricity and turn it on;
  • The system will start loading, the display displays the message “CMOS Checksum Error. Defaults Loaded. Press F1: To Continue “;
  • Confirm the reset of the settings by pressing the F1 key.

How to eliminate problems and fix the screen

The bad news is that some of the problems cannot be eliminated independently, so the help of a specialist may be required. But before that, you need to understand exactly what the problem is. If you have a second monitor and a system unit, you need to perform the following actions:

  • Connect another monitor to your PC. if it does not work, then there is much more chances that the problem is on the PC or cable side;
  • Connect your monitor to another PC. if in this case the monitor also does not work, then with a high degree of probability the problem is in it, and not in PC.

As a rule, in one family there is only one computer. But you can beautifully get out of this situation. if you live in an apartment building, you can ask your neighbors to help you in this matter. In this case, make sure that their system unit and monitor have the same connectors as your devices, otherwise such a text is difficult to consider relevant.

Problems with power supply

The power supply is a component installed inside your system unit. This component looks like this:

It is important for you to know that the current that enters your PC is distributed by a power supply between all components of your device. Each device has its own consumption, and if the total power of the power supply is not enough to power all components, then problems arise.

You can independently calculate how much the power supply should be in your PC to nourish all the components normally. But keep in mind that cheap models often do not correspond to the declared power. For example, 500W PSU in a low price category can issue 340-370W in practice. Therefore. you must have a reserve.

If you recently connected new components, and after that you have problems with the screen, then return everything to its original state, and then test. If you really do not have enough power, then the only option for solving this problem is to buy a new, more powerful power supply.

If the power supply does not launch the entire PC, and not just the computer, then the problem is in it. You do not need to be a professional to figure it out. Draw a simple test. pay attention to the indication of the block, as well as the coal. if it starts. If this test has passed, then look at the mother card. It has special indicators that show LEDs that food acts:

If one or more bulbs do not burn, this is a clear signal about the problems with this component. The bulbs are associated with components such as CPU, GPU, etc.D Sometimes the problem is not in the PSU, but in the components themselves, but here without special equipment or the use of the old BP on a new, 100% of the working PC, it will not work.

RAM problems

It is no coincidence that we take out problems with RAM higher than problems with the video card. since according to our own statistics, problems with the RAM are more common than with Vidyuha ”.

You need to conduct a visual inspection of the RAM plank. To do this, carefully unscrew the cover of the system unit and study the component. It should be densely placed in the mother map. If not so, then remove and place the component again.

Also check if everything is in order with contacts. Over time, they tend to block. They can be cleaned with an ordinary eraser:

If you have several ranges of RAM, then conduct the system test of the system alternately taking out one of them. Sometimes, if one bar has broken, and the second works, then there are problems with the monitor, it does not turn on when starting a computer. If you find this particular solution to the problem, replacing RAM, since, as a rule, such components are not amenable to repair and they are only replaced by new.

Problems with a video card

When the monitor does not turn on when the computer is turned on, it seems that it is impossible to find the causes and eliminate problems. but this is not so.

Most modern computers have two video cards at once. one built.in, the other external. As a rule, everyone uses external, since it is faster and more powerful. For the test, what went wrong, switch your monitor from an external card to a built.in. You can check the presence of a built.in card literally a simple inspection of your PC from the connectors:

If everything works with the built.in card, then consider that you have found the source of the problem. If there is no built.in card, but you need to find out the problem, then conduct an elementary test. start the system and pay attention if your PC has a culler at the video card. Often, when it fails, it is he who breaks.

Also check all the resistors and capacitors on the map. they should not be torn or swollen. This is a primitive test that will allow you without a specialist to identify most problems.

As well as in the case of RAM, do not forget to check the contacts. that the card is correctly installed and that the contacts are clean. Clean the connector if necessary and reinstall the card. Despite the fact that “yesterday” the card worked perfectly, it can accidentally “jerk” and this will be the reason why the work card does not work.

Problems with a chipset

This problem can be identified only in the service center. It is associated with the chipset of your processor.

We have encountered such a problem only once in a life of more than 10,000 devices with which we worked. Therefore, the chance that you have failed the processor. so minimal that you can discard it as an error that can be neglected.

As a rule, only very old processors break, but they also work for decades.
