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.

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
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.
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
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?
