Question about Denon AVR-3300 Receiver

1 Answer

Denon AVR-3300 has a buzz from all 5 speakers during warm up.

After the unit has been off for a while it will emit a 60 cycle hum and crackling sound from all 5 speakers (no matter what DSP/mode it is in) for about 10 minutes when turned on. Once the unit has been warmed up, it is quiet and exhibits no more problems. I have already had to re-solder several traces and am fairly familiar with the layout, but do not have a schematic or much of a clue where to start.

Hum created by Denon AVR-3300


Look for bad electrolytic capacitors. Swollen up on top or leaking, puffed out on bottom. If they look alright, you will need a capacitor tester to see if any have dried up. That's the first thing I check for hum.

Denon 1513 overheating


It's possible that it might be a fault on the unit. One or more of the output devices could have a thermal problem. However at 80 watts it might be driving the amp a bit too hard, maximum for it seems to be between 75 and 110. Are all channels capable of delivering the 80 that is the question? If one is capable of only 75, then the answer will be that channel is the one overheating.
If that is the case you would be better with an AVR that can deliver 100 watts on all channels. As for the choice go for what you can afford and look at the customer reviews closely. They are the best guide to a decent bit of kit.

My Denon AVR589 just started crackling like rice krispies, I've tried resetting the microprocessor, but no luck it still crackles. Is my unit fried?!


Is the sound from the unit itself (airborne) or is it through speakers only?

If the former, turn it off and take it to a tech to figure out what's sizzling in there.

If the latter, is it specific sources and/or specific speakers?

Humming sound (speakers)when HK AVR is powered up.


In my case the buzz was only on front speakers. There are 3 capasitors (100uF/25V) very close to the cooling ribs of 3 regulators in the power supply. In my case the C922 was bad.

Unit''trips'' off shortly after powering up


Disconnect ALL of the speaker wires from the back.  Turn it on again, if it still trips, then the unit needs to be repaired.  If it does not trip with no speaker wires connected, turn it back off, connect 1 speaker at a time and turn it on, when it does trip, that speaker that you just put on has a short somewhere, it could the be the wire or in the speaker.

Denon avr-1909 crackling sound while watching Uverse HD.


It may may the the AT+T box is really not compatible with the AVR or the Pioneer.

Check the specs on those input/outputs for the Ubox and the receiver.
See if they agree. If so, try another hookup method like HDMI ( which carries the audio too)

My guess would be +and -12v supply to preamp opamps has ripple. (drycaps or bad solder). I may be able to get you a pdf service manual if needed. kstahl65@att.net

Static from right from speaker


The noise is in the pre-amp stages of the Denon AVR. It might be caused by bad capacitors.
