So I left my PC and came back to the monitor orange standby light being on (as usual) but as when I moved my mouse to wake the monitor back up it didn't work. I tried turning my monitor off and on again but it did not work, the orange light just remained there. I tried unplugging and re-plugging in the cable but it did not work. The weird thing is that the orange standby light is still on even when the monitor has been unplugged for 10minutes, please help as I really don't want to buy a new monitor
