My Toshiba L455-S5009 laptop is only three months old and already it had developed a yellowish orange cloud over much of the display. This type of display uses led's to illiuminate each pixel, so there is no need for a lamp. I was told by a repair service in Mexico that the display needed to be replaced. Later that day I saw an identical Laptop at WalMart. Guess what? STAY AWAY FROM TOSHIBA LAPTOPS!
