Denon avr-2310 strange sound

[admin_exported]

I have a b-stock avr-2310 which was sent out to me by Denon as a replacement for my old reciever. The unit has what I believe to be a fault.

When I power up the unit from standby sometimes it turns on with the light flashing green and the unit making a click sound which is the same as my old 1909 and other times it will flash green but when it clicks on the sound will be much louder and sound in between something snapping and the case vibrating.

The unit was sent off through Denon to SST in west drayton last week who sent it straight back saying no repair was required. When I spoke to there engineer he informed me that the vibrating sound was coming from the mains transformer and is caused by power surges within the transformer which he said was quite normal.

I have owned 2 other denon recievers and about 15 integrated amps but never heard a start up sound like this. I have emailed Denon's engineer in Germany but he hasnt got back to me yet probably due to it being over the weekend. I am hesitant with this unit as Denon can not confirm its history or what it was previously used as or why it was sent back to them after a few weeks use. I spoke to a friend of mine who has a 1910 and his reciever makes the same click sound everytime he turns it on and off and his unit does not make the sound mine is.

Has anyone else experienced this with there units? Any advice is appreciated.

OK, just tried mine for you, using remote, one click, unit turns on, display is white, then does a bit of diagnostics, another slightly louder click and it shows last input used, screen stays white, no vibration. I would send it back.

I have an old demo 1906. It has been doing exactly the same thing, with the loud click and then sometimes a loud woof. I spoke to the shop that I bought it from way back when; they assured me that it was normal...

Anyway I have had it for just over 4 years now with almost continual usage and no problems yet. I will probably be upgrading to a Denon 2310 soon. Will let you know if it also has the weird clicks.

kiba have you bought the 2310 yet?

Thanks to Denon they have exchanged the unit for a brand new 2310. However the woof type vibration on power up is still intermittently present. It was not for the first few days but has come about again.

I can only imagine this to be something with the newer power supplies they are using. the sound still seems a little odd but as long as the unit keeps working properly I cant complain.
