I might have missed the beginning of this thread: when the screen goes
black can you still ssh to the machine (you may need to enable ssh, and
switch from DHCP to static IP for this test). 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.
