Laptop troubleshooting - Display Problem.
Those LCD screens look
nice, but they and the components that connect them to the motherboard
are relatively delicate. Any drop or jolt can cause display damage.
Screen problems come in a variety of types, each one indicating a unique cause. A completely black display indicates that the connection between the screen and the motherboard is loose or disconnected. Thin lines across the display are caused by a slightly loose connection to the motherboard. A dim image is most likely due to a failing backlight. Growing stains or blotches are a sure sign you need to replace the screen. If the display degenerates or scrambles after you have been working for a while, the computer is overheating. Dead pixels, which show up as tiny black, white, or solid-colored dots on-screen, are common, but there is no fix. However, many manufacturers will replace a notebook’s display after a certain number of pixels die.

these problems need the attention of a professional technician.
Attempting to fix screens is a difficult and delicate process and may
require substantial disassembling of the notebook, which could void laptop warranty.
