There is an internal ribbon cable that has given trouble in the past. If you or a friend are handy you could open the box and fiddle with it, in case it is loose or has a bad connection.
But, if the unit is still in warranty, probably better that you return it for replacement.
It could also be a faulty power supply – if you are not using the official one, give it a try.
