Answers :

Black screens can be caused by many things the first bit of video runs through the ram, so try changing the ram or swaping it. the next thing that causes a black screen is the LCD Inverter or the back light bulb to test this is take a flash light and shine it on the screen at an angle and see of you can make any faint images out. Next dis-assemble the laptop and see if the processor is heating up or staying cool.
