Answer to: Nexus 7 (2013) Screen is Black. (Can still hear notifcations)This will one of two thing. 1) The LCD cable is not in place right. 2) The LCD has gone bad. I am thinking your issue is the first one. If you can open the back you see a gold cable. This is the LCD cable. First make sure it is making a good connected to the main board. If it is then take a small Philips screwdriver and look under the charge port board to see if the cable is connected the right way. If this cable is connected the right way on both end then it's the LCD and it will need to be replaced.
