My p3 screen locked

I am the user of power plant 3, my power plant screen is locked, there isn’t any response with touching the front switch and remote, and neither my router couldn’t detect the power plant, but all the socket on the back is working and always on, I have no idea when this happened since I was using the hc socket in the past 2 week, after today I have move the device to new area and found out this problem. And because this p3 is not in warranty, with this situation, what can I do to this.
