It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.
SOURCE: stuck on standby
Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know [email protected]

Needs to be reset or fuse blown. Take to repair shop, cover has to be taken off and fuse replaced. You could fix it yourself but the warranty won't be honored. Do it yourself electronic shop should have a replacement fuse, may have to be soldered in place. Repair shop, should cost around $30.00 to $45.00 to fix, price of fuse $4.00 to $6.00. Your choice.

You're drawing too much power from it. Sounds like maybe your sub is hooked up wrong, double check that.
SOURCE: Denon DVD 910 won't power up. Light goes off then on.
Possibly a power supply problem, not enough power.
Could be these:
- dried up filter capacitors (electrolytic) - these include: main filter capacitor (the biggest one),
any final filter capacitors at each voltage output section, also at the oscillator end.
Check for any blown up, leaked or (partially) shorted capacitors.
- burnt out components (resistors, diodes).
Replace these (assuming you can still determine the proper value or type).
- poor solder contacts.
Remove the old solder and resolder the pins.
Dried, leaked or blown up capacitors may cause the power supply to crash down (or cycle with very low power output).
Burnt out components may act as a short circuit line, a change in conductivity (resistance) or as an infinite resistance (open contacts).
Poor solder contacts (so called "cold contacts") originate from bad soldering (at the factory), being further loosened by component overheating and tensile stresses (moving your equipement from place to place causes the circuit board to bend a little bit each time, and this, in turn loosens the solder contacts even further, causeing more overheating which may melt the solder, and so on).
You can tell a poor solder contact from a good one: bad ones will have a circular crack in the solder around the pin - try moving the pin a bit with a pair of tweezers - if it moves, there's your bad contact (you'll need a good light source and possibly a magnifying lens to spot these).
hopefuly you can get closer to a solution using these hints.
