What causes the screen to remain black with power on?
I recently replaced my laptop LCD screen and it was working fine until today the screen remain black with power on. So I opened both casing (screen and base) to see if there is any loose connection but all connection is fine. I put the casing back, start the computer and I have picture in the screen. To test if the screen is working properly I closed my laptop and reopen it, the result is black screen with no picture.
Is this a good question?
