I know you have probably already done this but my amp did the same thing one time. My problem was my aftermarket Audience Power cord was had pulled away just far enough out of the IEC receptacle. Pull your power cord out of the amp and plug it back in. Also check the source it is plugged into.
If this doesn't do the trick. You have probably blown a fuse.
