The monitor can t show it today, so it s urgent

Take it to the warranty. I bought it back and found that it was the whole house without power", when I plugged in the power supply this morning, a small spark came out just after plugging in the power strip, and then I found that the wiring board light was not on, and the wiring board had a jack in a little black, and one of the stainless steel gusses of the host plug (I don't know what to call it) was a little burnt, and it was a little unsmooth to wipe it with paper. ", the obvious phenomenon:

Short circuit. The monitor just lights on, but it can't be started, and the keyboard doesn't respond to the light not on. The mouse light is on. ”

The keyboard light is not lit, which means that the system has not even started the BIOS (generally when the BIOS starts, the keyboard light will flash for a while, and if it does not flash, it means that the BIOS has not even started.) ）

So, the failure possibilities are:

The motherboard was burned. (This is a possible factor for the BIOS not getting in.) Since it will flash for a while, it means that the BIOS is still in, but the monitor is not responding.

And, after flashing a bit, can the keyboard light come on again? (For example, can the caps lock light be on?) )

So I hope the landlord goes to the warranty.

Hardware problems,No network master can do it.。。。

Hehe, you're very good at narrating it, possible causes, your host problem, the simplest way to discharge the motherboard BIOS may be good It is estimated that you can't operate, please be a master, or the motherboard or CPU in your host is burned Hehe, then you will break the bank.

It should be caused by a short circuit! Your monitor's display tube may be burned out.

It is recommended to fix it! It shouldn't be much of a problem, just a spark, it doesn't matter!

It is recommended to find a monitor to connect it to try first.,Confirm whether it's a monitor or not.,If so, it may be burned.。

It shouldn't be that the display is bad.

When you encounter the issue that your monitor won't show, there are many possibilities that can cause this issue. Here are a few problems and possible solutions::

1.Make sure the power and data cables are connected correctly.

This is the simplest solution. Make sure your monitor is properly connected to the power and data cables.

2.Adjust the resolution of your display.

In some cases, your display may not recognize your computer's resolution settings. Try changing your computer screen resolution or refresh rate. You can try changing the resolution setting by right-clicking on an empty space on the desktop and selecting Display Settings.

3.Change the cable or interface.

Sometimes there may be damage to the cable or port. Changing the cable or using a different connection port may solve the problem.

4.Update the display driver.

5.Check for hardware issues with your monitor.

The power supply of the internal power board of the display is insufficient, and it is mostly a problem with the filter capacitors on the power board of the display! If you don't understand electronic circuits, it is recommended to send it to a local professional maintenance station for repair!

You can use the elimination method to see, and most of it is a display problem.

Obvious problem,2 years ago, I also encountered the same situation.,Turn on a few more times and sometimes it can be displayed normally.,Then it doesn't show directly.,The light keeps flashing.,It's just not an image.。

I went to Samsung customer service to check, and the result was that the power supply of the display was broken, and I changed it to an original 150The man recommended that I buy a new one directly.,Anyway, it's not expensive now.,But I bought the original imported Samsung display at that time.,The display effect is completely different.,So I decided to change the power supply.,Now it's easy to use.。

However, we still have to pay attention to maintenance in daily life, especially after shutting down, we must turn off the power of the display, it is hot in summer, and it is easy to break if the power is not turned off.

Therefore, it may be helpful to advise the landlord to check the power supply.

One: I still think the graphics card is quite a problem.

The first step is to replace your original monitor with another computer.

Check to see if it's the condition of the monitor itself.

If it is on, there is a problem with the host. Turn to the second step.

If it doesn't light up, the monitor is wrong.

Step 2: Because you hear a "drop" sound, it means that the hardware self-test is normal.

Sometimes you can see a hardware self-test message on a black screen. But it can't get into the Windows system. You can see if you can enter safe mode (f8).

If you can get in, there is a problem with the system.

If you can't get in, it may also be a hardware problem. Turn to the third step.

Step 3: Enter BIOS (press DEL) on boot

If you can get in, there is a problem with the system.

If you can't enter, you just can't see the BIOS interface. It's a hardware problem. Turn to the fourth step.

Step 4: If this happens after you accidentally touch the case, open the case, unplug the hard drive strap and plug it back in. By the way, unplug the graphics card and carefully wipe the gold finger with an eraser.

If the problem persists, the graphics card is most likely to fail. Replacement graphics card test.

Two: If you say that your monitor has a red dot, the graphics card is very likely to have a problem, but by saying that the windows display has a blurred screen, it is possible that the graphics card driver is damaged. Generally speaking, if the display still has red dots in the BIOS or safe mode or in the black screen state before entering Windows, it is a problem with the graphics card hardware.

If the display is normal in the above three states, but after entering the system, there is a serious blurred screen, it must be the graphics card driver. Now your keyboard is not good, so I can't help, however, there is a keyboard option in the device manager, you try to uninstall it, and then restart it to let the system automatically reinstall, can you solve the problem of the keyboard is not good. By the way, when I used to solve this kind of problem for other friends, I encountered a situation where his graphics card slot was AGP, and I asked him to change to a PCI graphics card, and the problem was solved, only to learn later that his agp slot was loose.

I don't know, can he give you some hints in this situation.

If you don't know where to start, it is recommended that you go to a small computer repair station and let a professional help you solve it for 10 yuan.

Hope it helps.

It can only be displayed after n times, which means that there is no problem with the three hardware of your host, graphics card, and monitor.

The problem is that there is a problem with the connection or setting, maybe the data cable is loose, remove it and plug it back in, after restarting, enter the window safe mode, try it.

It's simple

When you move, the host is going through**. Loosen the hardware inside.

According to what you said, I judge that your memory is loose, and the contact is poor, which causes you to not be able to turn on.

The solution is to remove the memory, wipe the gold finger clean with an eraser, and install it! That's it!

Hehe! Let me tell you.

This is the problem of your power board voltage regulator circuit, it should be out of the 5V circuit that supplies power to the main control board, take it apart to see if the capacitor on the power board is bulging, the general capacitor bulging is the performance of the internal electrolyte dry, and the capacitor is a component of the DC flow AC, when the DC is large, the voltage is extremely unstable, the above problems will occur, and the general repair is 60 yuan for one month. And the repair rate is high. If you know what to say, you can take it apart and take a look.

Is the VGA cable loose?

Look. The one in the back plugs in the computer and monitor cables.

Try again.

I was sturdy...

Your problem should be a common problem with the computer, it's very simple, first check the problem, see if your power supply is charged, whether the fan is turning.

If it's not a problem with the wiring, then that's it, you unplug all the cables on the motherboard that can be pulled out, and some hardware such as graphics cards are pulled out, wipe them clean, stay for a few minutes and then plug them back in place, if not, then please remove the motherboard standby battery, and install it again after a few minutes. Almost everything can be solved in this way.

If you turn on the computer and see that there is a lot of English, it means that you have succeeded, and you can not restart it when the English does not enter, keep pressing the "delete" key to set the system time, because you unplugged the motherboard battery so you have to reset it. Generally, it is below or above the first line, press the "F10 key" to save the settings after setting, and then restart the computer to be OK.

It's definitely not a problem with the display.,It's either a problem with the cable connecting your host to the monitor.,Or it's a problem with your socket.,,I'm guessing too.。

If the previous few can't solve the problem, it is recommended that you check the capacitance inside the monitor! There is aging, and the one that changed the drum is replaced....Personal opinion, for reference only....

Well, there are many reasons for this situation, most of them are caused by memory modules, graphics cards, moisture, dust accumulation, poor contact, you can get it yourself a little bit, if it doesn't work, it may be a broken motherboard or something... That can only be taken and repaired...

The bright orange light is in the power-saving state, plug the signal cable connected between the host and the monitor again, (VGA is blue, DVI is white) Replug both ends, and lock the screws. If it's not good, go to after-sales! Good luck.

The cup hasn't started up for a long time and can't work all at once, or the CPU is too hot.

Change a VGA data cable, about 10 yuan.

It may be that the VGA plug of your monitor and the socket on the graphics card are not in good contact, and it was not a collision before the break.

According to your description, the display is almost certainly normal.

You need to observe that when it doesn't show up, you need to make sure that the computer console is turned on properly. You can simply judge whether the power fan behind the computer is turning after turning on the computer.

Most of your cases are that the computer can't turn on normally every time, resulting in no display. This situation is basically caused by the leakage of capacitance in the power supply of the computer host or the motherboard, and this capacitor failure will cause a situation that is sometimes good and sometimes bad. You can find someone who is more familiar with the computer to try it, change the power supply of the host first, and see if the problem is solved.

You're sure the console is on, then the problem goes back to the monitor. "The plug of the monitor should be fine, unplug the cable that connects it to the host, and it will respond", the power supply of the monitor should be there, right? If the power light of the monitor is on, but the screen is black, check whether the signal cable connected to the monitor and the computer is broken, and check the circuit.

The backlight circuit or input AD conversion failure, for the sometimes good and sometimes bad faults, most of them are caused by a slight break of the signal line or a device soldering on the circuit board.

1 The power supply to the monitor is not plugged in.

2 It may be that the computer and monitor are not plugged in.

3 Then there's the computer problem.

The place where the power cord is plugged into is not in good contact, so adjust it.

It should be a problem with the host computer.
