Replacing the matrix on a laptop :
Screen matrix – an integral part of any modern laptop , dual cavity with liquid crystals inside. The matrix is considered to be its most fragile part . Repair of the matrix itself in its physical damage is not done. But problems such as faulty voltage converter loop or backlight can be overcome by means of repair. Used today in modern laptops LCD, and , unfortunately, poorly resist shock, vibration and pressure , they are vulnerable and easily fail. If you can not fix it, then the choice is made for the replacement of the matrix of the physical size and connection sockets on the motherboard .
