I had recently bought a new laptop screen to replace the broken one. I connected the video cable and everything. I plugged in the laptop and all I get is a black screen. I tried turning it off then on. I can't remove the battery. I unplugged, turned off then on, then turned off then plugged it back in, and turned on. It still makes the sounds it normally makes when its working. My laptop is a Acer Aspire E15 E5-553G-F55F with windows 10. I don't have a disk for repair. I tried an external monitor but that shows up black too.
