DVI line leads to black screen fault handling full Raiders

If the notebook encounters a black screen, I believe that friends will think of handing over the notebook to the merchant for repair. If the warranty period is still good, the problem will be great if the warranty is over. Notebooks are highly accurate products, and replacement after hardware damage is quite expensive. In particular, the motherboard is damaged, the merchant's offer is about 2000-3000, which is unacceptable. Usually, the black screen of the notebook screen is caused by some bad habits that we usually use during the process. After debugging, we can solve it ourselves.

Computer black screen is a very common fault, and the cause of this fault is also various, but one of the reasons is that you have encountered the black screen failure caused by the DVI line. This tutorial will introduce you to this tutorial. This problem, we look at the following examples:

Failure cause

In order to upgrade, I bought a dell u2410 LCD monitor six months ago, but because the integrated graphics of the old computer only vga The interface can then only be used with the vga interface of the display.

Recently changed a new host. I was equipped to connect the monitor to the host computer. I suddenly found that the dvi line that came with the monitor didn’t know where I was thrown. I continued to connect to the vga port. After playing for a while, the more I thought about it, the more uncomfortable it was. There was a computer shop downstairs. Going to buy a dvi line is not over. Soon, buy the dvi line and connect the host to the dvi interface of the monitor. After connecting with the dvi line, the display effect is really improved, and the browsing picture is more transparent. Just smug, suddenly I feel that the monitor in front of me seems to be black, how is it going, and then look at it, the display is normal, is it that I look at it?

Fault development

Facts Proof, Xiao Zhao really didn't look at the eye. When I used the computer later, the screen was black several times, and the screen was very dark, sometimes it was black for a few minutes, sometimes it was not black for half an hour, although every time The black screen is also about a second, so the computer that will flash like this, who can stand it. I think that when I just connected with VGA cable, it seems that there is no such problem, so I reconnected with VGA cable. After a few hours, I have never seen this problem.

It seems that there is a problem with the DVI output port of the graphics card. Fortunately, the computer host just bought it, so he called the technician. Under his testimony, he managed to find a boss to change a video card. I thought the problem was solved. Soon, shortly after the new graphics card can be installed, the screen is still the same as before, and an irregular black screen will appear. The boss also called and said that the video card that was replaced was no problem at him. Previous12Next page Total 2 pages
