3. 1. Faults caused by host power
black screen faults caused by host power damage or poor host power quality are very common. For example, when you add some new equipment, the display will appear black screen failure. After eliminating the quality and compatibility problems of accessories, the quality of the power supply is not good, and the lack of power is the main cause of the failure. At this time, you may also hear 12 continuous alarms from the internal horn. Replacing the high-power high-quality power supply is the best solution to this kind of failure. In addition, some motherboards have at / ATX al power interface, the wrong jumper setting can also cause this kind of failure
2. Faults caused by parts quality
?? Poor quality or damage of computer accessories is the main cause of black screen failure. For example, the main board (and the BIOS of the main board), memory, display card and other problems may cause black screen failure. Its fault performance, such as the display light is orange, at this time with the replacement method to replace the display card, memory, and even the motherboard, CPU try, is the fastest solution
3. Connection quality between accessories
?? The main cause of the black screen failure is the improper or loose connection between the memory graphics card and the main board. Moreover, problems with the connection between the display card and the monitor may also cause such failures, until the at power supply is not correctly plugged in. What's more, if your hard disk or CD-ROM data cable is connected reversely, it may also cause black screen failure
4. Black screen failure caused by overclocking
?? Excessive overclocking or overclocking of components that are not suitable for overclocking will not only cause black screen failure, but also cause damage to accessories. There is also excessive overclocking or to the components that are not suitable for overclocking. After overclocking, poor heat dissipation or the cooling fan is damaged in normal use, and does not rotate at all will cause the system self-protection crash and black screen
5. Black screen caused by other reasons
?? Others, such as incorrect CMOS setting of the motherboard and incorrect BIOS jumper clearing of the motherboard, can cause black screen failure. At this time, you can change the settings according to the instructions of the motherboard. In addition, software conflicts, such as driver problems, improper installation, improper DIY, such as BIOS refresh error, incorrect power management settings, hardware damage caused by malignant virus (such as CIH), and so on, may cause display black screen failure. When you encounter this kind of fault, you may as well think more carefully and consider the causes of the fault, so as to solve the problem, know yourself and the other, and get twice the result with half the effort< Second, the black screen failure caused by the failure of the monitor itself?? According to the author's common experience, the black screen failure caused by the display's own failure is mainly caused by the following reasons:
1?? The lack of external power supply causes some old displays or some displays with high power consumption can not start normally, which is one of the reasons for the black screen failure caused by the display failure. Or the external power supply voltage is unstable, too high or too low may cause the display not to work
2. The power switch circuit is damaged
?? The failure of the switch circuit is the main cause of the black screen failure. Simple, such as power switch damage or internal short circuit; Common such as switch tube damage or its peripheral circuit components damage, etc
3. Line output circuit damage
?? The main cause of display black screen failure is the failure of line output circuit or kinescope and its power supply circuit. In particular, the damage of high-voltage package is more common in some miscellaneous displays which have been used for many years or with poor quality< Third, how to solve the problem of display black screen?? For the display black screen fault how to repair, we will put forward some ideas for your reference< br />?? First of all, for the display black screen failure caused by the computer host failure, we can solve it from the following ideas:
1?? When you have a black screen failure when assembling a computer or replacing accessories, you should first check the installation quality of your accessories. For example, whether the memory mole is correctly installed, whether it is in good contact with the motherboard slot, whether the display card and other plug-in cards are installed in place, whether the relevant settings in BIOS and the jumper selection on the motherboard are correct, you can carefully refer to the relevant board instructions for setting, In addition, it is also necessary to focus on the quality problems of the board itself, as well as the related slots on the motherboard and the "golden finger" part of the card to check whether there are foreign bodies and dirt contamination< br />
?? In addition, whether the CPU is used by overclocking or "mistakenly" overclocking (especially for some motherboards with soft jumpers, the system's "automatic" error setting is more likely to cause this kind of failure), whether the hard disk or optical drive data cable is reversed, and so on, all need your consideration. And for this kind of problem, it's better to give priority to the "minimum system method" and "replacement method" for diagnosis, leaving only the main board, graphics card, memory and CPU to try, especially the high failure rate caused by the quality of the memory mole. If there is no problem, you can focus on checking the quality of other accessories, such as the black screen, Can focus on these accessories and then carefully install the connection to try to restart, if it can not solve the problem, the relevant parts can be replaced to try the quality of accessories< br />
?? In addition, it is very important that you also need to know whether the host power supply and power switch are good or bad and whether their connection is normal or not. They may cause the whole machine black screen, which you need to focus on. If there is a problem with the power supply, you can see that the indicator light on the chassis panel of the host computer is not on after you turn on the computer, and you can't hear the rotating sound of the power fan in the host computer and the self checking sound of the hard disk, etc., which indicates that your host system has not received normal power supply at all. For this kind of problem, you should first check whether there is AC coming from the outside, and use a measuring pen to see whether there is electricity on the power socket. Next, we can test whether there is electricity on the side of the power line connected to the host power supply. If necessary, we can use a multimeter to test whether the voltage is enough. If the voltage is too high or too low, it may cause the host power supply to have overvoltage or undervoltage. The automatic shutdown protection of the circuit. If there is no problem above, then you should first focus on the interior of the host and the power switch and reset key, Similarly, the minimum system method and replacement method are used to remove the power lines and signal lines of the host card and other equipment one by one, and then power on the test machine. If the host power is restored to work when a certain equipment is removed, it is the damage or improper installation of the newly removed equipment that causes a short circuit, which starts the short circuit protection circuit in the power supply and stops the power supply to the internal equipment, Then you can focus on the contact condition of it, and if necessary, replace it first and try again; In addition, it is very important to check the quality of the power switch and reset key and whether they are correctly connected with the main board, because the power switch and reset key on many inferior chassis often have the situation of power short circuit e to the fracture of the internal metal contact after several times of use, resulting in the black screen without any display. If the above inspection can not solve the problem, then please try to replace the power supply
2? When the computer has a black screen fault, the indicator light on the host panel is on after the computer is turned on, the fan in the computer rotates normally, but the alarm sound of the PC horn appears; Or in the case, such as hard disk and other related equipment normal self-test, but the display does not show. At this time, in addition to the above methods of maintenance, it is more important to learn to distinguish the PC horn error rule to distinguish the fault. In addition, it is also very good to observe the lights on and off of the host or display to judge the fault< br />
?? For example, the host normally self checks, but the display appears "black screen" fault. For this kind of fault, we can focus on the main board - display card - display connector - display. First of all, you can check whether the power indicator of the monitor is on. If it is normal, you can focus on adjusting the brightness and contrast button to eliminate the "common" false black screen fault. If there is no problem, you can focus on checking whether there is a problem with the connecting cable between the host display card and the monitor, whether the pointer in the plug on the cable is crooked and broken, and whether it is tightly connected with the display card. In addition, you can take off the cable connector to see whether the display can display normally or connect the monitor to other hosts, In order to determine whether the fault is caused by the host or the display itself< br />
?? For another example, if the display screen is black and the horn in the host computer emits a long, two or three short beeps or continuous beeps, it indicates that there is a problem in the connection between the display card and the motherboard or between the display card and the display. You can focus on checking whether the socket is in good contact and whether there is any foreign matter in the socket, and you can replace the display card to try. If it doesn't get better, it can initially indicate that the problem is on the motherboard, You can take the graphics card to other motherboards. For another example, if there is a continuous long beep, it mostly indicates that there is a problem with the memory mole. You can focus on checking the installation contact between the memory and the memory slot. If there is a continuous short beep in the aircraft, it indicates that there is a slight short circuit in the aircraft. The minimum system method and elimination method can be used to solve the problem until the short circuit part is found. In addition, if you hear two short beeps, it indicates that there may be a problem with the motherboard or the display card or the display. If you do not connect the display, there is a problem with the display card. If it becomes a short tone, it indicates that there is a problem with the display< br />
?? For the black screen failure caused by the monitor itself, we mainly provide you with more specific maintenance ideas from the following points
1?? If there is no display after the display is turned on, after eliminating the cause of the host, check whether the protection circuit of the display works e to too high or too low voltage, and check whether the voltage of the acceleration pole is normal. In addition, it is important to check the following parts that are prone to problems, such as whether the fuse is blown, whether the rectifier bridge switch tube is broken down, whether the current limiting protection resistance is burnt out, etc. sometimes these parts can be seen from the appearance that they are burned black and other fault phenomena. Then focus on checking the output tube, transformer, low-frequency rectifier tube, high-frequency rectifier tube and other key parts whether there is damage or performance degradation or false welding, general display black screen fault, as long as you start, you can quickly get rid of it< 2. Fault diagnosis of line scan circuit?? The failure of line scan circuit is an important reason for no raster and no screen display. For this kind of fault, we can focus on the line scan circuit. First, we can check whether there is a problem with the line oscillation circuit. In amateur conditions, in addition to checking whether the peripheral components of the line oscillation chip are damaged, we can also try to replace the line oscillation chip. In addition, the line drive tube is damaged or its working state is abnormal, The above faults may be caused by the damage of row output tube or the problem of row output load. At this time, you can repair and replace these parts. If there is a problem with the line output circuit, it will return to normal after maintenance and replacement
3. Fault diagnosis of kinescope and its power supply circuit?? Abnormal picture tube and its power supply circuit can also cause the black screen without grating when the display is powered on
black screen faults caused by host power damage or poor host power quality are very common. For example, when you add some new equipment, the display will appear black screen failure. After eliminating the quality and compatibility problems of accessories, the quality of the power supply is not good, and the lack of power is the main cause of the failure.

5. Where is the city center< However, those who can call the city center can be reached by subway
Tianhe City, sports center, Beijing Road, Yuexiu Park, etc.
this is the most convenient means of transportation. What's more, it's hot, so why take the bus?
Liwan pedestrian street should refer to the section from Hengbao square to the next nine. When you take the subway to Changshou Road station, the bus is very close from there, but there seems to be no through train.
by the way, I've lived in Liwan for more than two years, and I haven't heard of Liwan pedestrian street, hehe, Maybe it's because we don't call it that. There are many markets selling all kinds of specialized procts in Liwan. This is a very old city. Many things are not found in other places. There are many old alleys in Liwan District^^

The first difference between skin management and beauty salon: concept
as we all know, the general beauty salon is for the purpose of pure skin care. According to the needs of customers, combined with maintenance procts and beauty techniques, the skin surface can achieve moisturizing or whitening effect
skin management is to manage the skin, diagnose the skin of customers, find countermeasures, and use beauty instruments and skin care procts with therapeutic effect to improve the skin care through professional techniques. More than ten processes are completed by multiple professional instruments with unique probes, so that the skin can be treated and improved to the maximum, At the same time, it can also effectively prevent various potential skin problems
can be simply understood as: the difference between skin care management and treatment improvement management
In other words, long-term therapeutic management of our skin can effectively prevent skin problemssuch as acne, acne, red tide, sunburn, chloasma, acne print, coarse pores, fine lines, skin relaxation, dark yellow skin, etc
as like as two peas in skin management and beauty salons two: step
when we do beauty in beauty salons, we will choose the beauty items according to the condition of our skin. Beauty salons will provide corresponding packages for convenience and convenience, such as a 10 course of acne removal, and the procts and techniques used in each treatment course are exactly the same. Although choosing this course of treatment can achieve the effect of short-term surface treatment and protection, it can not achieve the cure and improvement of deep skin
before each skin management, we should make a diagnosis of the skin condition of the guests at that time, select the skin management that is more suitable for the day according to the skin condition at that time, formulate the most suitable management project, and select more appropriate procts
8. In order to provide comprehensive skin care for customers, beauticians need to adopt a whole set of nursing proceres. Each procere is not only interrelated, but also has its own different purposes and requirements. So, beauticians need to operate in strict accordance with the standard requirements of each procere, which is the decisive factor for skin care to achieve the best effect
1. Take the coat → help the customer lie flat on the bed → tidy up the customer's quilt, clothes and shoes → wrap the head and ask about the room temperature → check the materials again → disinfect the hands
2. Remove the eye and lip makeup with key makeup remover → gently clean the facial cleanser (pay attention to the proct flow in the corner of the eye, and wipe it in time)
3 Take photos (do not take photos with a mobile phone with beauty function) (make the customer's skin problems clear when taking photos) → analyze the photos
4. Conct skin detection for new customers for the first time (find out the problems according to the data analysis and give scheme suggestions)
5. Analyze the customer's skin problems through facial CT instrument and give appropriate nursing scheme
6 Make standard service process according to different nursing plan
