Win7 system is a good system that everyone likes, but recently many friends have reported that their win7 system has encountered some problems of normal host but the display is not bright! Today, I bring you a solution to the problem that the win7 computer monitor doesn’t light up.
Solution for win7 display not on:
(first of all, it has been determined that the following methods can be used to solve the problem that the display does not light up when the host normally turns on and the screen does not respond.)
1. Check whether the black screen of the display is caused by the power supply problem of the display, as shown in the following figure: try to plug and unplug the power supply and data connector of the display again, so as to solve the black screen caused by the power supply problem.
2. If the screen is still in the black screen state after the monitor power is plugged in and out again, you need to try a simple cleaning of the memory module to continue to eliminate the cause of the black screen.
Note: before removing the memory module, make sure that the host is powered off
3. In the case that the memory module is also cleaned, the black screen is still not resolved. You can try to remove the CMOS battery and power it off for a few minutes before reinstalling it.
4. If all the above operations do not solve the problem of the black screen of the display! Basically, it can be judged that there is a problem with the data line!
But to be safe, we’d better clean up the video card and check if there is any abnormality in the video card in an attempt to power on!
If it is not solved, it is recommended to replace the data line to determine whether the problem is with the graphics card or the data line.
