There is no brightness control, what could be wrong?

Monitor is Apple 30" Cinema Display, the brightness control button on the right is not working, try the the change over "display" through Mac OS, but there is no brightness bar there either. So, what could be wrong here? is this easy to be fixed?

Many thanks.
