Cable Box issue

Cable box was unplugged to move furniture. After project was finished, cable box plugged back in to power outlet. Cable box will not turn on. Any thoughts? 

This happened 3 weeks ago (for another project) and the technician came and simply turned it on magically. Is there a secret button I should knowabout Is it a simple fix? Or must I have a technician come and charge me for them to push a button?
