There are a lot of flickering silver dots on the laptop screen, what s going on?

1.Call 800 first to inquire about how to deal with this situation.

2.**Screen detection in Optimizer (free green software) to see the highlights (see if there is only 1 or several), the software Sky Pacific Software Park can be planted for free. If the information is a display failure, it is recommended that you immediately call 800 warranty, and then send it to the local service center to change the screen for free after testing, and the general manufacturer is 2 years warranty.

If you have passed the warranty period, it is estimated that it will cost about 1500 yuan (original) to replace the screenIt also takes more than 1,000 to get the computer city of parallel goods. After changing the screen, the warranty period is only 3 months.

3.All manufacturers have regulations, and only when the highlights reach a few or more can the screen be replaced for free, and 1 can not be replaced. However, if you say that the bag is good and there are no highlights when you buy it, you can insist on changing it.

4.Remember: the notebook three packs --- have quality problems, and they will be repaired in 2 years.

I hope you solve it soon.

Check the graphics card, whether the display cable is loose, and reinstall the driver, otherwise there will be a dead pixel.

Graphics card issues. Refresh more and more, right? Update the driver to try it out.

What's the deal with a splash screen on a laptop?

Splash screens and snowflake screens are mainly caused by graphics card problems, so let's take a look at three reasons for splash screens.

1. Splash screen caused by screen backlight.

Fault manifestation: The backlight of the notebook flashes from time to time, and the frequency is very fast, sometimes it flashes several times, sometimes it lasts for several minutes.

This situation is due to the instability of the high-voltage board that supplies power to the backlight of the screen or the ignition of the solder joint at the lamp joint is not firmly connected.

Fault performance: When the battery and power adapter are used at the same time, the laptop will flash from time to time, and the charging indicator in the lower right corner of the screen will be switched constantly, and the fault phenomenon will disappear when a single power supply is used.

This fault is mainly caused by the instability of the non-component of the battery switching circuit on the motherboard, and the fault can be repaired by repairing the components of the motherboard charging circuit. Don't be greedy to use dozens of dollars of power supply, this kind of power supply in the hand is fluttering, and the material used can be imagined.

3. Screen flickering caused by the defect of the screen itself.

The fault manifests itself as follows: Generally, there will be a bright line under the laptop screen at first, and after a short time, the bright line will evolve into a full-screen flash.

PS: The flicker screen fault indicates that the following delicate parts of the computer have been touched, and professional maintenance personnel need to deal with it, so as to avoid manual attempts.

Here's how to solve it:

1. If the display resolution and refresh rate are too low, reset it.

2. If the connection cable between the monitor and the host is loose, check the connecting cable.

3. If the driver is caused by a driver problem, update the graphics card driver.

4. If the graphics card is in poor contact or there is a problem with the display chip, plug and unplug the graphics card and wipe the gold finger part of the graphics card with an eraser.

5. Caused by signal interference, such as the speaker and mobile phone are too close to the display.

6. If the display hardware fails, this can only be sent for repair.

7. If the system is poisoned, it is recommended to reinstall the system.

Presumably a backlight issue.

If it is an LED backlight, then it is likely that there are LED strips with bad lamp beads or poor driving circuits;

If it is a CCFL backlight, then it may be that the lamp is aging or the driving circuit is poor.

In recent years, notebook screens have LED backlights; In the early years, the backlight of the notebook screen was CCFL backlight.

It may be caused by the graphics card. It could also be that there is a problem with your screen.

The common causes of screen failures such as screen flickering and screen shaking are: first, the quality of the screen itself, screen aging or inferior products, second, the screen line contact will not be damaged or damaged, and third, the motherboard screen power supply is abnormal or the screen failure caused by the virtual soldering of the graphics card BGA packaging chip, it is recommended that you send it for repair and testing.

During the warranty period, send the customer service for maintenance, free of charge (except for man-made damage) After the warranty period, I can help you in Beijing.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

Since the XP will not fail, it must be a software problem, and the hardware is fine, just change the driver.

It's over, the LCD screen is leaking.

It will be very soon, and that place will not be displayed.

But congratulations, the rest of the place will be fine.

Screen cable problem, LCD screen capacitance aging.

Let's change the screen !! That's called bright line machine as long as it's within the warranty range! Take it to an after-sales repair station for repair.

Cause.

1. Subject to external interference.

It is due to strong electromagnetic interference in the vicinity where the display is placed, such as electric sparks and high-frequency electromagnetism. If the intensity of interference is very high, it will cause the entire screen of the monitor to produce white horizontal streaks; If the intensity of the interference is not high, it can be characterized by a severe change in one corner of the display.

Solution: When these two situations occur, we must first focus on checking the surroundings of the display site to eliminate the equipment with strong magnetic interference, and in general, the problem can be solved.

Cause. 2. Subject to internal interference.

The performance of internal interference is very different from that of external interference, and if the display is interfered with, it will make the display screen of the monitor appear black horizontal stripes, and it is more serious.

Solution: In this case, we can open the case to check whether there is any bad contact inside the display, whether there is any problem with the output end of the power supply or the output transformer.

Cause. 3. The service life of the display is too long.

If the internal capacitor is too old, it will deteriorate and fail, resulting in too slow start-up, a dull screen, and blurred fonts. At this time, as long as the aging capacitor is replaced, the fault can generally be eliminated, but because it is also a very high-tech work, it is recommended to send it for repair.

Problem analysis: If the laptop screen is streaked, and the screen keeps flashing or even black, it is likely that the memory or screen cable is in poor contact, and it is not ruled out that the graphics card or display has a hardware failure.

Solution: 1In the current state, turn off the computer (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord), power off, disassemble the memory card cover on the back of the computer, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), and then turn it on after installation.

2.If the above operation is invalid, check whether there is a break at the screen shaft, you can try to pull the display screen to make it at a different angle to see if the screen has changed, if there is a change, it may be that the screen line is broken or loose, and professional repair is required.

3.If none of the above operations work, then connect the laptop to other monitors, if it can be displayed normally, it means that the monitor may be damaged and needs professional repair.

This is the reason for the poor contact of the screen power supply or signal line:

The upper cover of the notebook (i.e., the display part) is made up of an LCD screen; Screen drivers and high-voltage components, these circuits must have a stable power supply to work properly.

Now the screen of the notebook will flash and sometimes the normal means that the notebook and the screen circuit are not faulty, the fault is caused by the poor contact of the screen power supply or the display signal line, the power supply and signal of the notebook display screen are realized through the cable in the hollow shaft at the upper and lower cover connection shafts, and the interface of the line is loose or the power cord is damaged, and there is a fault phenomenon of irregular flashing or black screen.

Such a fault can only be solved by repair, and it is also easy to fix.

The power adapter has nothing to do with this failure, as long as it is a qualified power supply, although it can be used with confidence, the scrapped battery (such as a full use of power) such a battery is best not to use, otherwise it will sometimes damage the charging circuit of the notebook, so it is recommended to replace, the dimming and brightening of the backlight is just a role in the feeling, and there is no practical significance, so my suggestion is to repair it as soon as possible to avoid the expansion of the fault in the future, I hope it can help you.
