Kryptview A750 wont boot up.

Anyone had this problem? When I turn the box on it wont load up and there's just a blank screen. The display on the box just shows a 6 which I guess is some sort of error code but I dont know what it means. Anyone know how to fix it or whether it can be fixed. I presume its not because of the new encryption either as that would just scramble the channels not stop it turning on.

Any help is much appreciated.
