Hi,

When I woke up one morning I always turn my monitor first and my computer second and go off to brush my teeth. Coming back, the monitor was still off it seems. I press the power button many times until I realized that the monitor is possibly broke.  If I try to power on my monitor it will either do two things:  After a few minutes without power when I press the power button it will make the kind of sound I always hear when its turn on but nothing else Or After a few minutes and pressing the power button I will create that sound and may turn the blue light for a few seconds then gone again.
I know my graphic card isn't the problem since it doesn't matter if its plugged in or not and I don't feel like buying another 19"(200$). I used my old computer's monitor on this computer to manage with my daily stuff.

Please help.

I didn't find the right solution from the Internet.
