I have replaced a friend's laptop screen and the computer is acting strange. I have done this several times before and I have not encountered anything like this before. This computer is running on Win 8, not 8.1, he was using his computer through his HDMI since he dropped it and cracked the screen. When I installed the new screen it came right on with no problem and when it go to the display screen (where u hit any key and it brings up the login screen to input your password) whenever I tap the keyboard or mouse the screen out dark!!! and it will stay that way whether it is connected via HDMI or not. You can still look at the screen and make out what is on the screen but its working without the screen being lit!! When the HDMI is connected it works but only shows from the start the second screen and not the main screen like its set to dual screen. The Model laptop that he has is NP350V5C-T02US
Does anyone have any idea why this is happening? I'm thinking that its the drivers....
Thanks for all your help
Here's proof that the screen works!!!
