if it goes completely dark and blank then its the monitor power cable, open it up and solder it with a conductive metal, oor just give it to a shop who has the tools. if it was the video cable it would usually give a no signal warning
My laptop used to display with the screen 45 degrees open. Now it won't. It would despaly at 90 degrees open. Now it won't. I have to have the screen as open as possible to see a display on the screen. Any suggestions on how to fix this or is the pc on it's way out? From what you've written, I believe it's my monitor power cable since the angle at which it is open makes the difference between display or no display.
