The computer monitor has turned on black, what's the matter?

Answer:

Recommendations: first, the power may suddenly contact bad, there is no power supply; two is possible that your graphics card may suddenly be a problem, or burned out; three is possible that your monitor is not connected to the good connection. I suggest you make a self check according to three tips! I hope I can help you!
Your computer is not lost to the display signal, no signal will display black energy, to display power out re inserted after the boot, sometimes is a digital model and simulation model is not switching over, did not show
Is the indicator light normal when the screen is black?If it is, should be the display board is not high-pressure output, so the display backlight lamp is not bright, looks like a black screen (close to the display, should be inside the image), recommended to send maintenance repair shop under high pressure plate. Generally repair the high pressure board on dozens of dollars.If the indicator light is black, then analyze the power section. Power supply may be the problem, but there may be power circuit on the power board, but also may be the driver board on the power circuit, maintenance, I would like to around 50.
