I replaced my the laptop screen on my son's Asus FV503VM, and now it's black. The old screen had a crack, but there was some image on it. Now...nothing, on either screen. I pulled the new screen out and tried it on another laptop, and it is working, so I know it's not a screen issue. I'm worried that I burnt a connection or blew a fuse. Whatever I did, I don't know where to go next and any suggestions (even if it's "time to take it to a professional!") would be appreciated.
