I've restarted the computer both from the hd and start-up disk. STill no display. Also reset PRAM/NVRAM. Computer seems to be running based on hd sounds. Caps lock key lights when pressed. But no display.

I reset SMC as well. No effect. Wondering about the video card. The unit date is 2008. Not sure if repair is advisable.

That I can't ascertain, since it's something you need to ponder. I personally have no use for the new machines that can't be serviced by users.

Right. It just seems like the computer is running normally, but there is no display. Like it's stuck in sleep mode. Is there a way to output to another video display so I can do a complete back up? Most recent about 10 days ago.
