@mzacharias, thanks for the reply
@CharlotteSwiss, I'm still here
here is what the manual says in attachment, I think there is a mistake in the workflow at the step "Is the fuse bown" between YES and NO, do you confirm ?
And here is some precisions on the behaviour of my Denon (test done without any wires connected, except for the power) :
1) With the button ON/OFF on OFF position : I put this button to ON => the denon starts, the ON/STANDBY button is fix red (in standby mode and it's normal !)
2) I push the ON/STANDBY button, it blinks green during 7 seconds and after a click sound it stops and the ON/STANDBY button is blinking RED quickly
