Anybody help me please? A detailed do it yourself will be appreciated. i dont know much about hardware. thank you.

Your early reply will help me out greatly, please.

update: Just checked the display by connecting another monitor, display was fine. But at my own laptop, screen is pink and vertical patches fluctuating.
