Since the computer works fine with another monitor, now try the defective monitor on another computer.
Problem persists, you got a failing electronic part inside or the monitor cable.
SOURCE: Screen is dark or dead on my 17" Macbook Pro
This could be a backlight issue, a board issue or an inverter issue. Look at the screen closely, if there is a faint image it's either a backlight issue or inverter issue. To weed out between the two you can just order on inverter, they're 20 bucks on ebay, if that doesn't work, replace the backlight. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, you'll most likely have to google for guides that show you exactly how to replace the backlight or bring it in for repairs.I work for Mac Repair NYC and i have to fix this problem a lot.
