After the monitor turns black, try to light up the screen with a flashlight. You'll see the picture on the screen if the back light is broken. If this is the first time you do DIY backlight replacement, watch this Youtube tutorial: https://www.youtube.com/watch?v=jApBXLs-YmM

Please remember that it could be dangerous if the mercury vapor inside the back light breaks. And wear grounding straps etc so you won't damage the circuit boards.
