He strikes me as an Me guy <| sep |> These LCD screens are made up of several different layers of polarizers , diffusers , etc . Sometimes , one or more of these layers can get dirty from external elements water , rust , etc . These kinds of things are usually fixable . What you want to do is take the screen apart and clean any dirty layers . To do this , look at the screen , you will see the metal shield holding it together has some tabs . Gently pry the tabs up so you can unsandwich the screen . At this point you wanna be careful , since you ' re now inside the screen . Also , be very careful not to rip the little ribbon cable going from the screen to the back metal plate . Now , REMEMBER or write down the ORDER and DIRECTION of layers not only do they need to be in the right order to work properly , but also some layers only work when placed in the right orientation . Once you are confident you know the order and position of layers , go ahead and take them out one by one . The layers are not glued in any way , so this is very simple . Make sure to grab them by the edges so as not to leave any fingerprints behind . Find whichever layers has the dirtstains , and try removing these . Make sure to take your time and not scratchbendbreak any of the layers . A microfiber cloth and compressed air work best for cleaning the different layers . Once you ' re done , put it back together in the right order and test . If you ' re satisfied , make double sure all layers are properly seated and close it back together ! I ' ve done this a few times to clean dirty screens , has never failed to work . Its a really simple procedure too , so don ' t feel intimidated by it .
