Dieing monitor? D:

I'm using a Samsung SyncMaster 906bw monitor and lately the monitor won't display an image after being asleep for a few hours. There aren't any dead pixels and the monitor works fine when awake. The monitor power button flashes as if there wasn't a signal, i've turned off the monitor, unplugged the vga cord from the monitor and computer, unplugged teh monitos power cord, the only thing that will turn it back on is hard shut down of the computer. If it matters i'm using Windows 7 Home Premium 64bit, its on the balanced power option..
turn off display: 10min
put the computer to sleep: 30min
turn off hard disks: 20min
I haven't recently changed any hardware or any settings in my bios.
