@pavan60346 connect an external monitor to your Asus and see if that displays. If so, you know that it is your LCD that has failed. . It could be the backlight. Try this. In a darkened room take a flashlight and with your computer turned on etc. shine the flashlight beam at an angle against the screen. See if you can make out shapes of your desktop etc. If so, it's your backlight. If not then we have to dig a lot deeper
