I bought a 20 inch lcd tv for my room by sony ( I;m starting to had sony) but to the point i've had th tv for about a month and I also use the tv as a moniter too for my pc and now to top of the screen is light or white. It's weird... The screen looks ok at first but the top is a bit white. I have no idea why it is but is there any way to get rid of this. It seems like every sony product i buy always screws up.
