After turning on, there is a spark behind the monitor, and then the display does not light up, where

That's a phenomenon of ignition, and if there is no high pressure, there will be no picture. This problem sometimes protects, sometimes burns out. You open the back cover of your monitor and see if there is any dust inside, blow it clean with a pump bucket.

See if there is a black place, if there is a must go to the maintenance department to repair, if you don't try it will not be fired, if you will, see if it is ** in the fire, wipe the place where the fire is lit, and seal it with silicone. If you don't have it, you can go to the maintenance department to get a little, and the cost of going to the maintenance department is much less. Hehe.

1 It may be that the picture tube is burned, 2 The simple point is that a chip on the motherboard is burned, (I forgot the name).

You find a professional to repair it for you

Sparkling? Hehe, I want to ask the landlord, how did you see the spark, disassemble the shell?

It is suspected that the landlord may have seen the bright light from the electron gun behind the CRT through the air vents.

Upstairs is recommended to blow dust, this is not a professional don't do it, because it's too dangerous, if you don't get the machine to destroy people, let people blow after all, it won't cost a few dollars,.

If the monitor doesn't light up, there are generally a few reasons, and the cost will not exceed 50 yuan.

It must be an ordinary monitor, so you don't have to ask. The boards inside the monitor should all be burned out.

The luminous tube burned out, go back and report it for repair.

Hurry up and fix it!

What display, LCD, or ordinary?

Hehe, the fireworks that I bought for thousands of dollars.

This is a CRT monitor that you have been using for more than five years.

The common problem, in fact, is the same as the failure principle of the TV, the sound you hear comes from the high-voltage ignition, which is usually the dust that collects near the high-voltage pack, and the dust in humid weather enhances the performance of the computer (conductance.

Caused by the reduction), the high-voltage current through the dust to form a loop to produce arc discharge, high-voltage ignition greatly reduces the electronic energy required for the working of the picture tube, so there will be no grating fault, and in serious cases, the failure of the chain will cause the fault of the output transformer or the line tube breakdown. You are still able to plug in the power supply, which means that it is only a high-voltage leakage ignition and has not damaged other components.

The solution is to open the back cover, then remove the dust and use a hair dryer.

Dry, but be careful not to use too much force or blow hot air on a certain place for a long time.

Otherwise, the fault surface will be increased, and it is necessary to pay attention after removing the dust to prevent the zero device from being damaged or the lead wire from falling off.

By the way, a monitor like yours, even if it's not humid weather, the usual brightness should be much better than before, and the colors are not as bright as before.

The monitor leaked and burned.,Still use to look at it.。。。 Estimate the capacitance problem.

I guess it's damp.,You smell it separately.,Do you connect the power of the monitor to see if there's still a picture? If there is no picture, it's a matter of the display.,If it's the host burned.,It may be the power supply or the motherboard.,That's it.,The probability of power supply is greater.。

Supplement: The power supply is better, the Great Wall can be, you must pay attention to it in the future, and you must not be damp.

As you mentioned, it's definitely the computer that's sparking because you haven't plugged in the power cord of the monitor yet.

The monitor doesn't show, it can't catch fire, not necessarily! It may also be shown.

The display screen doesn't respond.,The first consideration is to show that I'm out of power.,Secondly, consider whether the display screen is a phenomenon.,If there's a problem, if these two sentences are not,Then you can only throw it away.。

Are you saying that the host can't get up, so the monitor will not be displayed, my computer has had such a situation before, my husband removed the memory module and brushed it with a brush, and the carriage was blown with a fan, and it can be used, I hope it can help you.

You can try the elimination method:

1. The display screen does not display when it is turned on, it is not a blue screen, there is no self-test and no output, which means that the new graphics card is not recognized, or the graphics card is broken, and it is not a system driver and hardware conflict.

2. The new graphics card can be used when inserted into other computers, and it is obvious that the card is good.

3. GF8600GT can be plugged in and can be used, indicating that the hardware connection is normal (memory and other hardware are not plugged in well may also cause no display of the boot graphics card), there is no dust pressing problem, HD5450 power consumption is a small water pipe compared to 8600GT, not a power supply problem.

4. The motherboard graphics card interface is incompatible, but PCI-E and are compatible, it should not be this problem Conclusion, it may be that the motherboard is too old and cannot recognize and support the new hardware, you can see if the motherboard manufacturer has a new BIOS, refresh the BIOS and try it.

1. Restore the monitor to factory settings, as shown below, press the auto button of the monitor, so that the monitor will automatically adjust the display screen to the best state.

2. The display mode is adjusted incorrectly.

Some monitors have both widescreen and square display modes. If you select the wrong mode, the display will be incomplete or unable to display the full screen. Solution: Press the MUNE menu key to bring up the display adjustment menu.

Find the options for "Widescreen Display Mode" and "Square Display Mode" among the options. to achieve full screen display.

Different monitors are different.

You mean you want to burn the monitor, just set it on fire, but don't burn the house hahaha!

Get a new graphics card, and again.

Broken, right? What does it mean?

(especially if the interface is not plugged in or loose), there may be a problem with the data cable of this connection, so there will be no signal input to the screen, no display, black screen, solution: just re-plug the data cable of this connection.

2.The second reason: due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, the memory and the memory slot are in poor contact, and the graphics card and the graphics card slot are in poor contact, resulting in a black screen, none.

3.The third reason is that the graphics card's video memory is soldered, the performance of the main chip is degraded, and the graphics card BIOS is wrong.

Computer display.

Libra Composite Index Three Stars Today's Libra, after the water retrograde, you are not in a very good mood, and you always feel insecure in your heart. The advice to you is that inner firmness can make you feel more secure, and the way to do it is to focus on one thing.

Reasons: 1. The display is broken;

2. If the connecting line is broken, if it is broken, replace the connecting line;

3. The memory module is too dusty;

4. There is a problem with the battery;

5. The motherboard is broken.

Here's how:

1. If something goes wrong, analyze it from the outside in. First of all, see if it is a simple display problem, plug in the power supply of the monitor separately, and see if there is a response. If it's just that the monitor is broken, you can replace it with another one;

2. If there is no problem with the monitor, check the connecting cable, whether it is connected, if it is broken, change the connecting cable;

3. There is no problem with the connecting cable, open the case, carefully take out the memory stick with your hand, when you take it, just press and hold the things on both sides of the card, and the memory stick will automatically come out, and then use the eraser to remove the dust;

4. If the dust of the memory module is removed and there is still no response, remove the battery of the motherboard, leave it for about a minute, and then install it;

5. If none of the above operations are performed, it means that the motherboard is broken, and the motherboard should not be disassembled by yourself, in case it cannot be dismantled.

That does not rule out that it is a lack of power Try charging.

You should check it out with customer service.

This type of failure includes not only the failure caused by the display equipment or components, but also the abnormal display caused by the defect of other components. In other words, the failure of the display is not necessarily caused by the display equipment, and should be comprehensively observed and judged.

2. Possible fault phenomena.

There is no display when the computer is turned on, and the monitor sometimes or often cannot be powered on;

Display color cast, jitter or scrolling, display blurring, blurred screen and other search types;

Under a certain application or configuration, the screen is blurred, dimmed (or even black), ghosted, frozen, etc.;

Screen parameters cannot be set or modified;

The brightness or contrast is not adjustable or the adjustable range is small, the screen size or position cannot be adjusted, or the Fan Shichai circumference is small;

abnormal after waking up from sleep;

The monitor smells or has a sound.

3. Components that may be involved.

displays, graphics cards, and their settings; Main wide board, memory, power supply, and other related components. Special attention should be paid to the interference of other equipment around the computer and geomagnetic fields.

It should be the aging of the motherboard. Most of them are caused by moisture.

How long has it been? Bad contact.
