Make sure you are using the main power button not the standby button and you should be fine

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

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 DRA397 Panel lock on.


Hello,

Denon has for some reason removed this function from their user manuals. However The manual does show how to do a manual reset of the unit. This may correct the issue.

With the Amp OFF but plugged in, press and hold the speaker A and B buttons and while still holding them press the POWER button. Continue to hold the speaker buttons for another second or so. The display should all light up and flash at 1-second intervals. If not flashing, try again.

This should reset the unit back to factory state with the front panel lock disabled.

Standby light stays red and will not turn unit on.


Try to reset the macroprocessor. Unplug the unit from AC, hold both buttons SPEAKER A and SPEAKER B and plug the cord in outlet. After display flashes several times release the buttons. No result? - repair shop.

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?
