PINK VERTICAL LINE APPEARS ON LCD

FOR LAST FEW DAYS A PINK VERTICAL LINE APPEARS ON THE LCD SCREEN OF MY LAPTOP.
THE LINE DISAPPEARED IN BETWEEN BUT IT IS AGAIN APPEARING FOR LAST TWO DAYS.
THE LINE OCCURS AS SOON AS I BOOT THE LAPTOP.
I HAD GONE THROUGH THE PREVIOUS POSTS WHICH GIVES IDEA OF CORRUPTION OF PIXELS.
PLEASE SUGGEST SOMETHING TO OVERCOME THE PROBLEM.
