tried the hair drier.. no major effects.. I'm affraid to try another display because this one has much more live colors then the rest..
having the same issue.. used WD 40 to clean the sim slot and it deteriorated my lcd, it has been like this for some weeks, but recently i've been looking on the web and decided to try some methods, I will try the hair drier later on tonight and in the weekend ( if the problem is not fixed ) i will dunk it in a container of uncooked rice. Wish me luck! P.S.: I'll be back with the results
