This problem started occurring recently and I do not recall making any changes to my system that would cause such a problem. My Sony flatscreen/widescreen monitor will not turn off even after I shut down Windows. The monitor's on/off button doesn't respond no matter how many times I press it or how hard I touch it. The on/off button simply remains an orange color when I shut down the pc and the screen goes blank. It turns green when I turn my pc on. It seems like a hardware issue with my monitor but I'm hoping others can give me their opinion on this too. Thanks!
