Audio Systems: home theater system, denon adv, internal fuse

Question
I have a Denon ADV-M51. Will not turn on,when I try to turn on power light turns to flashing orange and no display or anything at all.

Answer
When did it start doing this? Have you changed anything in your system recently (speakers?)...

There may be an internal fuse blown... I would contact Denon, as there is probably a code in the flashing orange (different malfunctions might have a different flash pattern)
