I bought a Sony Vaio Vgn-FS640 laptop months 18. I noticed on the LCD screen screen that appears in the right corner of the LCD 1 vertical line that moves between the colors yellow, white, and sometimes appeared blue.Then 2 lines then 3, then 4 times getting thicker. Someone please help. Thank in advance.

This is a common problem known as dead pixels ... "Before trying to capture the meaning of a dead pixel, first you need to understand the technology behind LCD displays. An LCD is essentially composed of pixels. Each pixel is composed of red, blue and green valves. The valves in each color either block or pass the source of light. By manipulating the amount of light passes through, each pixel shows a distinctive color on the screen. Pixels consisting of these valves are what make up the image that finally appears on the screen. A typical monitor has millions of pixels. A dead pixel refers to a pixel with a defect in the ability to display the correct color output. May seem like a small black dot on the screen, or any other color that does not correspond with what the actual image should look like. A typical 17 inch monitor contains up to 4 million pixels. Even a small particle of dust in one of the pixels during the manufacturing process can create a dead pixel. Or a slight bump during shipping can break one of the pixels highly sensitive.
