What's wrong with a computer monitor without a signal?

Often have friends will encounter a monitor without signal, compared to display without any display, monitor no signal computer failure is easier to solve. Why do you say that? In fact, the reason is very simple, if the monitor does not show any, we can not easily judge whether the problem is a monitor or computer host problem, and when we connect the power supply to the monitor, the monitor can quickly know that there is no problem with the monitor, so the problem is mainly in the computer host or connection The following article I will share with you under the computer monitor signal-free solution.

First, let's talk about the reasons why the computer shows no signal:

⒈) Monitor Data cable host connection is loose or has fallen off

⒉) Monitor data cable damage (this is rarely the case, mainly to note that the pins are not bent or broken pins)

⒊ Computer Host internal problems (such as loose memory, graphics loose, poor video output interface, etc.).

Next we introduce the computer monitor signal-free solution:

For computer problems, we generally start from simple to complex, first of all the more common connection between the monitor and the computer host data line exists loose, bad contact, when we encounter a computer monitor without signal should first look at the monitor data line is good, in addition if the computer using a single display platform, The data cable should be connected to the video output interface of the graphics card, instead of the motherboard's video signal output interface ' another more common is the computer memory strips loose or too much dust caused, causing the monitor no signal, the most obvious situation is that the computer inside as if everything is working normally, but the monitor is not signal. This problem is more than a long time in computer use, for a long time did not clean up the dust is likely to appear, the solution is to remove the memory, with a paper towel to clean up the memory of the gold fingers, and then install back to it; another is that if the video card, the card loose will also appear similar problems, it is recommended to reinstall the video card can

There are some other reasons that happen less, for example, the data line is bad, data line pins or memory or video card damage, etc., the last case is the computer boot without any response, open the chassis to see what is not running, this situation may be the host power is not connected or power supply or motherboard failure caused, this problem is more serious , need to take to repair and solve.
