Try a different monitor and cable if you have it to make sure it's not a problem with the PC, but it sounds like the backlight inverter in the monitor is going.

I'd check the power cable, I've seen a similar issue with that in the past.

this just happened to me with 2 different monitors , they would power on ,act like they were on . but no image, even had the green light. one of the monitors had a bad inverter. and the other one had an external psu , and it went bad. one is a little easier to fix then the other , lol. shine a flashlight on the monitor , and see if you cant still see a faint image of whats on your desktop. if you can then you might be able to fix it

Weird - I have exactly the same issue with a 17" Belinea with an external power pack - comes on on initially and goes off within a second or two. I took it apart and couldn't see anything obviously wrong inside. Now I'm wondering if it's the power pack....
