Are you a technician?

First place to look is for open fuses. Next, does a relay click, and then
the unit depowers ? If so, primary of main ( not standby ) power transformer
may be open. It's quite common for primaries to fail open on Denons of
various models. Fault monitoring circuitry checks rails after main power
relay closes, and if any ( or all ) are missing, unit drops back to standby.
Failing this, it's going into output protect. As Mark says, you might
struggle, particularly with a Denon, if you are not an experienced engineer.
They are not the most fix-friendly of designs ...
