Anonymous users2024-02-04Cause of the failure. The first is a system problem.
The second type is a software problem.
The third type is the residual file of a software virus.
Fourth, the software is incompatible.
Fifth, the cache settings are unreasonable.
Sixth, the system is under-resourced.
Seventh: viruses and Trojan horses.
Eighth, the hardware is overheating.
The ninth type of hard disk.
The tenth type is hardware quality.
Type 11 Hardware overclocking.
The twelfth type is the hardware environment.
Pseudo black screen workaround.
1: When you want to boot the computer, restore the BIOS to its factory state first.
2: Close all startup items. (msconfig) in Run (tick) ctfmonand anti-virus software.
3: You copy the following command. At the command prompt, type:
regsvr32 /s
regsvr32 /s
regsvr32 /s
regsvr32 /s

4: Update the graphics card (or sound card. mouse, etc.) drivers. Restart your computer again. Do a comprehensive antivirus.

Anonymous users2024-02-031. Hardware failures can only be judged by the elimination method. If the black screen is ruled out as a software problem, it will focus on the cables, lamps and high-voltage boards of the display.
2. It is best to change the cable and the lowest line, and give priority to replacing the line. Moreover, the cable replacement time is very short, and it does not need to be fully disassembled, and the screen can be turned on after the replacement line proves that the cable is faulty.
3. It is easy to judge that the lamp is broken. Even if all the lamps are damaged, the screen still has a slight light when changing the viewing angle, and when the wallpaper is white or yellow, you can see the wallpaper color. In the dark, you can see the glimmer of the screen very clearly. From this, it can be judged that the lamp is faulty.
4. If the above two are tried, the rest is the high-voltage plate failure, and this kind of failure is the least encountered in daily life.

Anonymous users2024-02-02The pseudo-black screen may have something to do with the wiring, high-voltage board, lamp, etc. A true black screen is a problem with the graphics card or screen display.

Anonymous users2024-02-01This contempt needs to be disassembled to know,The easiest way is to take a good screen to your computer to confirm whether it's OK,If not, it proves that your motherboard is broken,Defying what you said about the normal system proves that there is a problem with the display module,For example, the graphics card or backlight signal, etc.; If it's OK,Then you need to rule out whether it's the wire of the screen,In the same way, you can take out the screen cable in your screen and replace it with a good screen to try,If the good screen is not displayed after replacing the screen cable, then it's your cable that is broken......Otherwise, there is a display to eliminate the problem of the cable, which is the problem of your screen......If the screen is broken, it may be that there is a problem with the converter circuit of the DC-DC circuit, which causes the screen to be unable to light up (the so-called high-voltage board, in fact, the current LED screen voltage is already very low, not the previous LCD screen needs to be high-voltage to light up the lamp), and now laptops use LED lights to emit light, so there is no lamp situation, and the PCBA design in the screen is a ...... in series, so if you don't disassemble the machine to judge it, it's basically impossible to ......It is recommended that you send it to the customer service department....

Anonymous users2024-01-31To test the quality of the lamp, you need to use a special test board to test!
According to your description. The monitor suddenly goes black;
It's most likely the display itself;
It is still recommended that you use the elimination method to confirm the problem first, and first move your monitor to a friend's computer to try it out to see if the screen will go black!
Or press the monitor on/off button, if the monitor will glow or there are characters displayed, it means that the monitor is OK, otherwise the problem is in the graphics card.
1.The problem with the display should be between the high-voltage board or the lamp tube!
Specific points: due to the ignition of the lamp to the overcurrent protection of the high-voltage board and the aging of the lamp, or the instability of the components on the high-voltage board to the black screen! In your case, the possibility of the high-pressure plate being broken is relatively high!!
2.If it is a problem with the graphics card, you can check whether the fan rotation of the card is normal or remove the graphics card to clean and wipe it before installing it, if it is not possible to quietly argue, then replace the graphics card.
There is also a VGA output next to the notebook Take a VGA data cable and connect it to another monitor to see if there is an image If there is, there is a problem with the laptop screen But it may also be the cable of the notebook The contact is not good If there is no image, it means that it has nothing to do with the screen of the notebook, it is likely that there is a problem inside the notebook But no matter what kind of phenomenon it is, you can't get it yourself Even if you can get it right, then you have to disassemble it, but there is no warranty in this way, you still have to find customer service directly.
Summary. The solution to the Dell laptop with a black screen and 7 consecutive alarms is as follows: >>>More
Wrap a protective film.
But in fact, you can also do without it, at most the screen is dirty, go to the general computer supermarket and buy a cleaning kit to get it. >>>More

There are several reasons that can cause this situation, unplug the graphics card, wipe the gold finger on, and try to update the graphics card driver.
