@susu23 first you want to make sure that it is your LCD. Connect an external monitor and see what that shows. Should that show the same defect as your laptops LCD then you know that you are having a GPU (motherboard) issue. If the external shows a normal image, consider replacing your LCD. Take a look at [http://www.myfixguide.com/manual/razer-blade-2014-disassembly/|this guide] and [https://www.youtube.com/watch?v=yyl02BzLL-A|this video.] Combined you see how to remove and replace the LCD.
