Hello! I am glad to assist.
The only thing you can try is to unplug the power cord from both ends and plug to a new outlet, then plug in the power to the printer.
Try to turn the printer on. If that works, then it might have been a loose connection or bad outlet.
If that does not work, then the power supply has gone bad and will need to go to a service center for repair.
Let me know how it goes.
