This article mainly explains "what to do if the signal line is not connected by the computer". Interested friends might as well take a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what to do if the computer shows the signal line without connection".

The computer shows that the lack of connection of the signal line is due to poor contact of the memory bar or display data cable, or damage to the memory, graphics card, monitor and data cable. The solutions are as follows: 1, disconnect the chassis and reseat the memory bar; 2, replace the memory bar; 3, replace the new data cable or graphics card; 4, carry out professional maintenance.

Operating environment of this article: Windows7 system, DELL G3 computer

What does it mean that the computer shows that the signal line is not connected?

Is the memory bar or monitor data cable contact is poor, or memory, video card, monitor, data cable damage.

Suggestions for handling:

1. If the monitor is powered on but shows no signal, turn off the computer (if the short press of the power switch is invalid, press the switch long until the power indicator goes off or directly unplug the power cord), turn off the chassis, reseat the memory stick, and use the rubber to wipe the gold finger in one direction (or scrape the nail back of the thumb), install it and then turn it on (release your own static electricity by touching the wall with both hands or wear antistatic gloves before operation). If you can't operate, make it simple: just slap or kick the chassis (attention: the center of the shell on the left and right side of the chassis where there is no interface behind; attention: don't push too hard). The above may need to be repeated, and if it is not valid, you need to replace the memory stick. If you have more than two sticks of memory, you need to test them one by one.

two。 If the above operation is not effective, power off and open the chassis, reseat the video card, and tighten the data cable between the monitor and the video card. If it is still invalid, consider that the data cable or video card is damaged, then replace the new data cable or video card.

3. If the host is connected to other monitors and can be displayed, or if the local monitor is connected to other normal hosts and still cannot be displayed, it means that the monitor is damaged and needs professional maintenance.
