CDJ-900 NXS won't start properly

So the 900 nxs we have at work decided to not start up past the flashing lights in the buttons like normal when you start the cdj up. The screen doesn't glow at all and nothing happens past the on/off flash of buttons, in, from what I can tell, the normal order.
It was serviced by an authorized professional just a month ago and I have never seen anything like it. The other player works just fine. What might the problem be and how do I fix it?
Thanks in advance.
