Q: cinema display tally light flashing

My 30 inch Apple Cinema Display keeps trying shut down my computer; the tally light is intermittently flashing, off, and then flashing, and then off. Is there a hardware test I can do? A way to reset the monitor?

OS X Mavericks (10.9.1), Attached to Mac Pro 3,1
