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 you change it, it will be about 50.If the indicator light is black, then analyze the power section.

First, if the computer is turned on and the monitor is not on, it means there are three possibilities after the boot screen does not show any:1, check the monitor power switch is open;2, the display power cord pull out, re inserted, check the power line of the display is inserted firmly inserted;3, the display is bad, please repair or purchase of new.Two, if the "computer after the boot is not bright" refers to the black screen after the boot, but there are English shows "no signal input" (no Signal), then there are three possibilities:1. Display the data cable of the host computer, insert it again and check whether the data line is inserted;2, if it is an independent graphics card, then pull out the graphics card, wipe the gold finger with an eraser, and then plug it in again;3, if the above two steps are still unable to solve, then it is likely that graphics have been bad, can borrow a normal card inserted for testing, if borrowed graphics signal display, then you can determine the required graphics card has been bad.
