Well I tried, but when I unplugged everything, the light still flashed and then slowly stopped. When I plugged everything back in it was just like before.
I`ll check the monitor again but I think it's fine because when I unplug this one cord from the tower and message comes on the screen about checking the connection for that cable or whatever.
The monitor has only one power button and when I turn it on the light turns green then goes to orange.
