If it is either a black or white nowtv box make sure that the power lead is fitted tight into it's socket at the rear of the box.
Also try a factory reset to see if the box restarts (see link below how to carry out a factory reset).
Try these two things first.

If it's another nowtv device, then just ignore my post.
