Problem with my CDJ 1000 not switching on.

Hi, I went to switch on my CDJ 1000, it wouldn't switch on like it normally would, I pressed the on and off switch, but there were no signs of it switching on, so, I decided to switch the Digital Out button, then, on the screen it said "d-out" , but nothing would work! I switched back to CDJ mode, but, still nothing would work! Does anyone know the problem? As I thought a fuse might have blown, but if it can still display the "digital mode", then this can't be the problem. Any help would be much appricated. Thanks.
