I also encountered the same problem half a year ago. You can try to connect the laptop to a regular monitor to see if it is the laptop display. If it works as normal. Maybe the flex cable that passes from base to screen. Then you can try to boot to a floppy. If your laptop lcd screen works, that would be an indication of an operating system. http://www.yallstore.com/laptop-lcd-screens-c-720_1204.html
