I own a ASUS K52JR-X5 laptop, and sometimes the screen flickers or freezes and fades away. When it flickers, horizontal lines of gray flash over the screen. In order for it to display correctly, I have to hit the screen lightly which can't be good for the computer.
I found one other person who had a similar problem, but since it happens sporadically, Asus technical help said nothing was wrong. He ended up giving up on the computer.
I figure it's something wrong with the connection , and I am tempted to open it up to see if there are any loose connections, but seeing that I haven't openned up a laptop before, I figure I'd ask for your opinions before I do that.
