Protection error in denon avr-3000
Do you know what caused the protection shut down in the first place? Did you short your speaker wires even briefly?
You could try to Unplug the Unit for Few Minutes, say 30 minutes and then turn it back ON.Usually that would fix the issue.
If you are going into protect mode with no speaker attached,chances are that your output Ic is in need of replacement .This is the most likely cause of a protection error that you are experiencing.I am having a bit of difficulty in locating specific part numbers but feel confident that replacing outputs will remedy your concern.For further info and parts or authorized service locations in your area I suggest to contact mfg at www.usa.denon.com/ .Click on support or call(201)762-6500.I believe that they have a flat rate service and will give you an estimate.
Still, on the remote possibility that it is just a glitch caused by momentary power interruption or fluctuation, try to re-initialize the microprocessor, a hard reset (not unless this is what you were referring to as rebooted). The reset should force the AVR-3300 to revert back to factory defaults removing glitches, errors in settings & configurations, memory & presets as well as user preferences.
* turn OFF the unit using the POWER button;
* press and hold both SPEAKER A and SPEAKER B;
* without releasing the 2 buttons, press the POWER button;
* release the 2 buttons only when the display starts to flash;
* in the event of no display flashing, repeat the process.
Should the above be not corrective, then it would be a hardware fault and not just a glitch.
Let me know, if needed further assistance.
