The screen goes black after more than ten seconds of booting, and the desktop can be displayed after

Hello. Is it normal for the indicator light to be black when the monitor screen is black?

If it is, it should be that the high-voltage board of the display is not output, so the backlight tube of the display is not lit, so it looks like a black screen (look close to the monitor, there should be an image inside), it is recommended to send it to the repair shop to overhaul the high-voltage board. Generally, it costs dozens of dollars to repair high-pressure plates.

If the indicator light is also black, then it is necessary to analyze the power part. It may be a problem with the power supply, but it may be the power circuit on the power board, or the power circuit on the driver board, and I think it will be about 50 if it is repaired.

I've had a similar problem with my Samsung, it seems that the panel is aging.

Is it when the hardware is tested or when it first enters the system?

There may be several aspects to judge:

1. Whether your PC is running normally and whether it is booting normally.

State. There is no access to the operating system, if there is a condition you can change a monitor and see. Also check if your PC has a screensaver?

Or auto-hibernation! Setting the screen saver is too short, only a few seconds (very unlikely). Graphics card issues:

2. Eliminate the problem on the PC side.

Or is it a problem with the monitor side, a cable problem: plug it back in, check the VGA or DVI interface. The back end of the monitor is not connected to the PC

Plug it directly into the power supply.

See if the monitor will light up, and whether the power light of the monitor will be red or something else, if it is red, it means that the power is on.

And normal. When the PC is connected, the power light turns green as normal. If the screen doesn't light up, the light won't light up when the screen is black. If you try to change the power cord again, then there must be something wrong with the display end, and the power cord inside can be poorly contacted.

3. No more, check that the system is free of viruses. It can only be a heat dissipation problem, after a long time, you can open the case to carefully sweep the dust inside, add a little high-grade oil to the fan, and the main problem is to reduce the temperature in the case.

4. It is not possible to restore with one click, if you do not prepare a system CD, the optical drive can be used. Start the computer and press the DEL key, set it to a disc boot in the BIOS, insert the system disk and reboot, basically complete it automatically according to the steps.

5. If it is other problems with the PC.

Then you need to find a computer repairer to deal with it.

The computer display screen went black after three seconds of turning it on, and it was a mistake in judgment.

When the display is displayed normally, some parts will heat up and expand, and then the place of virtual welding will be disconnected, and it will naturally stop working. Therefore, your monitor needs to find someone to check the corresponding solder joints, but the workload is too large, and it is difficult to ensure that the virtual solder joints are accurately found, and the asking price will be relatively high.

There are many reasons why a computer has a black screen, and the common ones are:

Shows poor contact of the data cable; There is no power supply to the motherboard; Poor graphics card contact or; Poor CPU contact and overheating; Poor contact of memory modules; poor power performance; The machine is infected with the CIH virus and the BIOS is refreshed destructively. Microsoft black screen, please patch Most of these problems are the relationship between memory and graphics card, loose or poor contact, just move it or use the eraser to erase the gold finger of the interface.

System problem:Boot loaded with multiple software,For example, QQ Thunderbolt pps or something is loaded on boot.。。 In this way, it will take a long time to enter the system.

After entering, use 360 or the like to optimize the boot, and then check the hardware installation problem.

Shows poor contact of the data cable; There is no power supply to the motherboard; Poor graphics card contact.

The system boots too slowly, you can reinstall the system, presumably it won't be so stuck for you.

There are many reasons for a black screen.

1) The monitor is powered off, or the monitor data cable is in poor contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break;

2) There is no power supply to the motherboard;

3) Poor contact or damage to the graphics card;

4) Poor CPU contact;

5) Poor contact of memory modules;

6) The machine is infected with CIH virus, and the BIOS is refreshed destructively;

7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger;

8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, and the computer will have a black screen and cannot enter the system. To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

The first method: start-run-msconfig and disable igfxpers. The second method:

Start-Run-Enter regedit in the runtime, and delete the key igfxpers in the hkey local machine software Microsoft Windows CurrentVersion Run in the registry (i.e., do not run the igfxpers program when you start the system).
