The fan only kicks in when a threshold current is drawn by the system. under normal operation it is not turning. Crank up the volume and you'll notice the fan fires. You wouldn't notice this since the system is so friggin loud!!

Sound volume knob does't respond

Chances are that it's a digital volume control.

The fact that it turns down again means it's probably fixable.

Open it up (switch it off first), and fetch a soldering iron. Look around for wires that go from the volume control and see if any are loose connections/broken wires etc etc. Solder these again, and it should work.

If you don't fancy this, take it to a hifi shop and they'll fix it for you (there'll probably be a fee involved)

Have you unplugged it from wall since ?
and, do you know if maybe the speakers are blown?
Bad speakers will make it stay in "protect"
Try other speakers after the unplug-plug back in routine.
Try the Denon website for a manual

SA-AK95 volume control problem

This volume controls is actually what is called an encoder. The control itself needs to be replaced. Figure on $5-$10 for the part plus the local labor rate for the total repair cost.

Sound setting

There are several complaints in FIXYA and they are all about this same fault conndition....the volume is too high when turned on...

Because of the high number of complaints about this same fault I would suggest that its a manufacturer fault.

So the manufacturer should be contacted about it to ask for your money back..

Cheers From YUBEUT..
