If you can ssh, this will mean kernel is still happily running, if not, then kernel might have panicked. I would do what Mark suggests: clean it to avoid overheating (but don't do it yet, until you pinpoint the place where it fails). BIOS turns the machine off completely when temperature threshold is tripped, so tripping temperature sensor threshold is not your case as your screen backlight is still on. However, overheating video chip may do what you see. And it also may open some micro crack. I also would do the following: attach external screen, make them both ON, and see if only internal panel goes black or both of them do. Tell us what your experiments reveal.
