Q: 24" Cinema display is flickering every 30 seconds or so. Has anyone found a solution?

I have a 2009 Power Mac tower with a 24" cinema display also 2009. About a year ago the display started flickering, like it was turning on and off. I've got a duel display set up and the other one (older acrylic 20") works fine. I've checked the cords, updated to the latest soft wear, at least I think I have. I see others having the same issue. Has anyone found a solution? This is really annoying when trying to do graphics work. Any help would be much appreciated
