I have a VGN-FJ270 Sony Vaio Laptop. The problem is that suddenly while i'm using the laptop, the screen appears all in read or blue or green, it happened to me in three times in different days. I do not know what could it be, so please if u do, let me know.
The first thing to do is to plug it into an external monitor or TV to see if it happens on that too. If it does, then your graphics chipset is faulty which will mean you need a new motherboard. If it doesn't then you most likely need a new screen.
