I have occasionally encountered the problem of a malfunctioning screen. At home, if you do not have enough experience, opportunity, and special desire to go to the service center, you can try to make an initial diagnosis of the problem. For this purpose, you will again need an external monitor. Connect your notebook to the DVI or VGA ports of the monitor. If after that, on the monitor screen will be visible a familiar picture - most likely the problem with the matrix, matrix connector for the plume, or the plume itself. Another way out is replacing the RAM line, which may also be the cause. But all the same, solving this problem by yourself will be difficult!
