Probably damaged by power surge. If you do not have experience diagnosing and repairing electronic circuits as well as having access to schematic diagrams then this is not a repair for you. Failure to replace all damaged components may result in damaging new parts.
Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck
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.
I have a Denon AVR-3000 and want to turn on the B Speakers. I have hooked up my subwoofer to the B connections on the Denon since there is not a subwoofer connection. How do I turn the B speakers on without a remote
Your unit was probably damaged in shipping. Denon is a nice unit! Do you hear any clicks when you hit the power button??? You should hear two relay clicks. You should hear the power relay click at power on and 3 to 5 seconds later you should hear the speaker protection relay click if your audio amp section is ok. If you hear both relays click then your display circuit is at fault. Open the unit and look for breaks on the front pcb (behind the display) and on the main board in the power section ( where the fuses are ). Good Luck!
Does it still power up for a little bit or so with no sound what so ever?....I there is no dents in it or metal pushed in causing cracked connector boards....I can take it off you hands for a couple parts I need ...because your transformer and 2 resisters are shot and it will cost almost as much as the unit cost's.
I do have a brand new never opend $649.99 Denon AVR-788 for $365.00.
And 2 used AVR units Denon and Onkyo.....ALL HDMI
Psgolfer ...I pretty shure you dont need that. It just needs to be reset, its in protect mode.....hold the power button down and the A n B speaker buttons down at the same time for 30 sec.....ok , Radricktip
I have one and the same thing happened. try resetting your microprocessor and if that does not work, then check the wiring of the speakers. if that is working fine and no wires are touching then I unplugged everything and was still having the issue. took it in for service and it was found that the transmitor was shorted as the speakers that I was using was too high in ohms. it is possible that it could be your caps also if resetting the microprocessor does not help. You can find out how to reset the microprocessor from your manual. If you have the Denon avr 887 with the system turned off hold the power on button and the speaker A and B at the same time for a few seconds. This is compatible to rebooting your computer. Hope this works for you as this was and is my husbands favorite past times.
