I am using an acer aspire 5750 series laptop for the past 2 years and it has been used almost daily, when suddenly a few days ago i noticed something odd on my laptops screen it seemed like a black patch and i thought that something might have stuck on the screen. After cleaning the screen with the cloth and the liquid i couldn't see any results when i finally realized that the black spot on my screen was actually behind the screen. it seems some kind of black lines that are not very dark have appeared on a little right to the middle of the screen and now i have realized that more of these lines are coming up, even though they are not that dark but yet i am afraid about the screen. i even tried taking the screen shot but that black lining spot does not appear on the screen shots.It looks like a map of sri lanka has appeared on my screen out of nowhere. Before i go for a fix to the service place i need to know what exactly has happened. i don't want those guys to trick me and make me change my whole screen it would be very great if any one of you experts could help me out.
