Ask for help What is the reason for the temporary black screen of the monitor, the intermittent blac

I change the sponsorship battery to a new one.

Failure Probability Analysis and Solution:

1. Problems with the link line of the monitor.

If it is a DP cable, if the display supports HDMI, you might as well use the HDMI cable to test it, many netizens on the Internet have encountered the problem that the DP cable appears that the display screen is black and bright, and there are still many problems that the HDMI cable has been replaced.

2. Problems with graphics card drivers.

It may also be a problem caused by the graphics card driver, you can try to update the graphics card driver, or uninstall the graphics card driver, and reinstall the graphics card driver. It may also be caused by the loss of the graphics card driver, the problem of the graphics card itself or the problem of the graphics card driver; You can use 360 Driver Master or Driver Wizard software to drive, and then try again.

Routine check-up methods

For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing the most suspicious parts first. For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine. If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Update your next PC management software.

The landlord seems to be an expert in the display.,But if the expert can't check the cause of the problem.,I think it's better to send it for repair.。 Before sending it for repair, please take this monitor to another computer to test whether it is normal, if it is still not normal on another computer, it means that the monitor is malfunctioning. If it is normal on another computer, it means that the host (graphics card) is faulty.

First of all, use another host to determine whether it is a problem with the graphics card, if it is determined to be a display problem, then it is necessary to check whether the secondary power supply filter capacitor and the data synchronization circuit are faulty.

Look at the VGA plug, is it disconnected, have you checked the power supply of the monitor? Is the performance of the switch module poor? The performance of the line pipe is also poor?

First of all, let's take a look at the system, if it doesn't work, it can't be explained, I've encountered a lot of this inexplicable problem recently, I guess, probably AMD's CPU cooling problem
