Hello,

This is a common indication of a failure in the power supply. There are parts called capacitors that are used in the filter section of the power supply, when they go out the power supply can't properly turn on so you get no picture and a flashing power light. Here is a picture of the power supply board with the problem filter capacitors circled in yellow and below the picture in a link to a repair guide with details dis-assemble and repair instruction along with parts list for the Dell 1905FP and 1907FP models.

Sounds like it is in StandBy. You should be able to press & HOLD the power button to shut it down completely.

Dell 1905FP powers up but screen goes black after a few minutes
The monitors inverter seems to be failing. If you look up close, can you see a very faint image of the desktop?

You should think about getting a new monitor it might be cheaper than repairing.

Dell monitor flashing green power button black screen.
Your computer is in sleep mode, a low power mode that conserves power by turning off the screen and hard drive.

Push the power button on the system and the computer will resume.

If you don't like this feature, you can turn off sleep mode in the power options in Control Panel

You may have bad caps (leaking/bulging tops) in the power supply or blown fuse. This is what the board looks like.

1905FP Monitor Powers up, briefly shows logo, blacks out.
Look inside for bad caps with bulgng tops, worst case will be shorted out transistors in the backlight inverter circuits or bad lamps. Check to see if you do have he 12vdc for the inveter circuits. See example of failed monitors with bad caps here: http://s807.photobucket.com/home/budm/allalbums

Pop goes the weasel...
Chances are a capacitor has blown. They normally make such lovely poping noises when they die.
What will of course now be happening is the voltage inside where that capacitor was will be unstable and it could very well completely fail in the near future.
I would reccomend you get it to a repair shop sooner rather then later for a cheap simple repair rather then an expensive monitor replacement.
