Just a suggestion this.
Could you connect your LapTop to a seperate Monitor. If you can you will then see if it is your screen or not. If you get a good picture on the Monitor then the problem would be with your Screen. If you still had the problem on the Monitor then it would be a Problem within you LapTop.
If you can do this then at least you would know where your problem lay.
Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before.
Edgar Allen Poe
