I have a Denon DRA 397 receiver and when I power it up the standby light goes on but nothing else powers up?


If you are not pressing the power button on the remote that may be the problem

Denon dra 397 shuts done if I turn on both zone a & b. Have a 100 watt volume control on each pair of speakers. Works fine with only zone a or zone b on, but not both.


Let's understand this - you have an external volume control wired in series with each front speaker set?

Can you elaborate on their electrical characteristics?

The scren says panel lock on. how do i get out of this mode


Denon panel lock was not supposed to be supported on this model, somehow yours is. We need to reset the microprossessor.
as denon manual states:
switch off the unit by pressing power.
keep both speaker a and b pressed and turn on the unit by pressing power.
check that the entire display is flashin at 1 sec intervals and release buttons.
the mircoprossor has been reset.
if step 3 does not work start over again.
the receiver will go back to factory defaults.
let us know if further troubleshooting is needed.

Cheers!

Denon receiver (DRA 397) will not speak to iPod dock


IF YOUR NOT USING A DENON IPOD DOCKING STATION IT WILL NOT FUNCTION CORRECTLY.
YOU CAN CONNCET OTHER TYPES OF IPOD DOCKING STATIONS BUT YOU WILL NOT HAVE CONTROL THROUGH THE DENON AND ONLY CONNECT THE AUDIO FOR THAT DOCKING STATION TO THE DENON AS ANOTHER SOURCE INPUT

Stereo receiver is in a Panel Lock On mode and will not stay on


Hi, Press the B and the Mode buttons and then hit the power button.  This should unlock the panel....it worked for me.

Remote lock on


This worked for me, but I'm sure tired of constantly searching for ways to fix the problems I encounter with my Denon DRA-397. When it works, it's great, but I don't have a degree in electrical engineering. Why can't they produce a user friendly trouble shooting guide?
