The flashing power button is an indication that the power supply has failed. There are parts called capacitors that filter the output power and when they short out the power supply can't start up correctly os it tried over and over, this make the power light flash each time it tries to start up. The monitor is easy to repair if you can do a little soldering. Here is a link to a repair guide that will show you how to dis-assemble the unit and what to look for and replace to get it back going again. Te guide also has videos showing the steps.

I hope this helps, if so please rate my solution.

This type of monitor problem is usually cause by a failure of the capacitors in the power supply board. What is happening is the power supply is not starting up correctly so the back lights are not coming up to full brightness. Here is a link to a repair guide that will show you how to dis-assemble the unit and repair the power supply board.
If you can do a little soldering then you can do the repair yourself.

When a monitor goes black and the solid green starts flashing it normally means the computer is sleep mode the screen saver blanked out the display the comp is off ect... However in this case since i assume you allready tried wiggling the mouse tapping the spacebar pressing the resume button ect... It is one of 2 things either the video card is going bad.( perhaps the computer has been on for a while and it is getting hot.

No matter which part solves the problem I reccommend you do the other maybe premaintenance things I suggested. Good Luck.
