Question about Denon DRA-397

1 Answer

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

My Denon DRA-397 display reads "Panel Lock On", and the REC, Z2 & Z3 are on, too.

The stereo comes on, but without any sound, then the display becomes blank; however, the power button remains on (green). I have attempted to contact the Denon tech assistance in NJ, but they are only open M-F.

    Same problem here.  My grandson came over and BAM! Display and Remote Control got "Locked"


    I've even unplugged and attempted resetting the "microprocessor" although that won't work as the display and panel are locked.


    Any help out there?

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

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?

Denon DRA-397 - the stand by button light is blinking red and I have tried the reset but it did not work. Does anyone have any other ideas?


You may want to check your output transistors,They are the ones mounted to the big heat sink.With a ohm meter measure across one of the legs to another there should be no shorts.If you see anything burnt that channel will be bad causing the unit to stay in protect mode to prevent futher damages

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

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?
