If the screen is still doing it then it seems likely that it may be caused by random power fluctuations or something in the monitor itself - obvious solution is to turn it off.
If it stops doing it then it's possibly getting random signals over the monitor lead from the gfx card that cause it to wake up. Try a different lead, (shielding maybe a factor), rerouting it away from power leads, etc.
Or the simple solution, turn the monitor off.
The Event Log on the computer will show if it's the computer powering on at random times which causes the monitor to wake up.
If the monitor is lighting up without the computer being on then it's a hardware issue.
