I hope it can be solved as soon as possible!!!Unplug the monitor power supply, can be restored, but less than 2 minutes, and the emergence of a black screen, can vaguely see the black screen flashing white light, do not look carefully, see, hope someone can guide, see what the problem is, thank you
How do I know the screen is normal?Is the screen normal when you enter BIOS?
If the power of the display can switch off the power, direct repair. Yes, the power panel is out of order.
First of all, is your video card driver normal? Second, your graphics card hardware is normal enough? Third, if you have the motherboard integrated VGA interface, then pull out the card, plug in the motherboard, VGA interface test, to see if normal. The above, if you exclude, then the display of high voltage board problems, high voltage instability led to display failure, the need for professional maintenance department monitoring, this if you are not professional, can not give accurate solutions.
