How do i reset avr-1705 denon amp?
Before you reset, are you doing this because the amp went in to some sort of protection mode?
Resetting will allow the amp to redo the self diagnosis. But if the problem remains then the amp will shut down again. Resetting doesn't fix things like bad wiring or blown output transistors. So only reset once you are sure you've checked through the system for any problems.
As a safety measure, disconnect your speakers before doing the reset. If the amp goes in to protection again then it is an indication that there are either shorted speaker outputs inside the unit.
Unplug the unit from AC power for 30 minutes, and disconnect all of the speakers and other associated equipment. Upon plugging back in, press and hold the power button at the same time for 5-10 seconds to force a hard reset.
If the unit starts up normally start connecting the speakers one at a time (shutting the power down before connecting each one), until one of the speakers causes the receiver to shut down. This speaker is faulty and would need to be replaced.
If the unit does not power up with NO speakers connected, then it needs the output transistors replaced inside the unit. These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink. In this case, the unit is in need of service.
