Have you check all connection to see if they are right, check if no cable was unplug, if you have and yet no picture display, It could be that the picture board on your monitor has started malfunctioning, since the power led or button is on, it means the picture board of your monitor has developed fault.
The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.
