My laptop screen in the last day started getting a silver tint with a white border that covers approximately 70 % of the screen.  I cannot see into the silver tint.  This tint will go away for a few minutes and will always come back.  I had to connect to an external monitor.  Any idea on how to fix without replacing the monitor....or should I say buying another laptop due to the expense of a new screen?  Any help would be appreciated.
