Question about Denon AVR-3300 Receiver

AVR-3300 Static and Sound Loss

I have had this receiver for about 10 years now (same one my father has, of which he has no problem of course), and about a year ago it started to make static noises (crackling also) and would start to loose sound.

The input does not matter and also the sound output (stereo, DTS, Dolby, 5 channel). I can literally type the front of the receiver (no harder than a flick) and the sound will come back on for a short period of time.

Also, I took the casing off and noticed that the fan is not running which I assume is not good, but that aside, whether it is 3 minutes in or 3 hours in the problem still persists....any ideas? thanks

Re: AVR-3300 Static and Sound Loss

The Denon Curse.......the connectors that the input boards ( up and down if your receiver is in the normal position ), plug into one of the 2 main boards on the bottom. These connectors are suspect and need to be cleaned and re-soldered. Same with the board that runs from the input side of the unit ( right behind the front panel, running across the unit ) to the amplifier board. Denons were HORRIBLE for bad connections with these. This is an involved repair requiring the entire thing to be pulled apart. It is not an afternoon job for a do-it-yourselfer, take it to an authorized Denon repair shop, as I GUARANTEE that they have seen this problem many times for all models from 2000-01-02-03. Good luck..... Rob

I have a buzz / static that appears for the first 15 minutes.


I just opened up an AVR3300..It's trouble is that it goes into stndby
at once.
The BIG power supply caps are VERY swelled at the top.

That would be my informed view on why it's bad.

I suggest you look at that being your possible trouble too.

Denon AVR-3300 Center Chanel Sound Problem

My guess is You have dried out electrolytic capacitors causing failure. These receivers when they get over 6 years old start drying out fluid in capacitors especially on regulator p.c.b. causing noisy supply lines. I work for Authorized service center in Michigan If you need repair and Shipping to Michigan is economical let me know

The AVR-3300 power-off to stand-by mode

You have a blown amp or a leaky cap and the unit is going in to save mode to avoid destrying the unit.

Take it in for a repair. I don't think it should run more than $50-$75 for a fix depending on what component is bad.
