str-dn 1080 stand-by high power-consumption

mirrormurr — Thu, 31 Oct 2019 08:33:17 GMT

Hi all,

Finally had the chance to measure the power-consumption on this receiver, whooping 59 watts in stand-by, and while playing loud around 75-90 watts. This cant be normal..?

Also noticed a slight 50 Hz hum from what I presume is the transformer, regardless in stand-by or on mode. Have read another thread regarding the Wake-up-LAN feature missing on European models and high power-consumption, but I thought this deserved its own thread.

Have to add, that I've opened a ticket to the support, I will keep you all posted

59 watts in standby mode, wow! My APAC region model uses 31w to 35w with Network Standby enabled. Alot higher than the advertised 1.5w (now removed from the Sony website):

This will be my 3rd attempt to continue this thread, previous updates were, weirdly enough not posted, but here we go:

Long story short: receiver is going to rehab, Sony support acknowledged the problem after a couple of emails with the usual attempts: reset, unplug all devices, update software etc. which had no effect, with this reply:

" Kindly note that the unit now will need to be inspected by an engineer as the explanation you provided does not look within the specification of the product.

In this case, you may refer to your local Sony support for further assistance with the product."

"Not within parameters" is in my opinion, quite an understatement; the specifications on any European site still states the 0,4 w consumption on standby and 1,5w on network-standby as opposed to my device using 59w!

And then follow gloomy days while waiting to get that crispy sound back in our living room..

Thanks for the update. Sony tech support are not replying to my support ticket. It's been 3 months since their last reply!

I would be interested to see if they can fix it, because there a bunch of other people whose receivers most likely use more than 20x the advertised specifications!!

little update for you waiting to see if the power-beast can be tamed;

device is now waiting for a new transformer to arrive from Belgium, so it's gonna be another week or so until I can give a full report on how it all went,

After 3 months of silence on my support ticket (Sony engineers were supposed to be investigating the issue), I chased the ticket up. Guess what? They started the whole troubleshooting steps script from the very beginning again!!?? So I answered their questions and now dead silence again!!

How frustrating, after the last report I got on my repair, I don't have high hopes to resolve the high consumption issue. I didn't pick up the device yet, but the tech-guys in elvia.cz had the transformer replaced and claimed the high standby power-consumption is like this by design. To me it looks, Sony made an error while having the str-dn 1080 on the drawing-board and chose to lie about it afterwards.

Gonna do a few tests and give a full report in a couple of days when the receiver is back from rehab..

Somehow I'm not at all surprised. Thanks for the update.

Got the receiver back from the local authorized repair-centre (elvia.cz) and after a replacement of the transformer, I can sadly confirm that the Sony STR-DN1080 has a serious design-flaw.

The stand-by consumption has been reduced from 60w to around in 30w, in any stand-by mode, with or without hdmi-pass-through and the hum is fortunately less present as before the repair, but still audible in a silent room.

The repair-centre confirmed that the part replaced was an original, had to be ordered from Belgium, which indicates it had to be some kind of a no-standard transformer and that the unusual high stand-by consumption was as they put it "due to the construction of the device"

Now I am actually wondering if this device actually should be allowed sold on a European market, as it must be in violation of all kinds of EU-regulations.

Re: str-dn 1080 stand-by high power-consumption

grolschie — Sat, 23 Nov 2019 09:19:57 GMT

That is probably why (in my opinion) Network Standby is missing from the Settings menu on the EU version of this receiver, i.e. to avoid using more than 12w (or whatever the EU regulation says, I forget) when on Network Standby.

This makes me suspect that they knew all along. Because if the receiver only used the advertised 1.5w on Network Standby, then there would be no point in disabling this feature on EU models because it would be well within EU regulations already!

Just my personal opinion/guess.

Re: str-dn 1080 stand-by high power-consumption

mirrormurr — Sat, 23 Nov 2019 09:46:22 GMT

Yeah, I also suspect there is some shady decisions concerning the network-standby and EU-devices.

Nevertheless, 30w is still 60 (!) times more than allowed for a device that has been shut down or is at low-power-mode, at least taking these regulations into consideration:

Here it says 3 to 12 watts for Network Standby depending on the device:

I really wish I could get my money back on this amp, it's not fit for purpose in my opinion. It might sound great but it has so many bugs that it needs an overhaul. Wake on lan doesn't work, idle standby is 30 watts if you enable remote start or whatever it's called and now the HDMI-CEC issue with it always opening up the Home screen for no obvious reason.

Exactly, it's a great sounding amp but just massively let down by the software inside that Sony seem to have no interest in fixing. By using the HDMI-CEC feature I thought I'd got around the nonsense of having no wake on lan available ( like my 6+ year old Yamaha amp did flawlessly while using virtually no power in standby...) but now with the stupid thing of it opening up the home screen instead this amp is just infuriating.

(Just registered to post here)

I bought my STR-DN1080 early 2018, and noticed a similar issue late last year. I expect it had be sucking 60W permanently for a 18 months by that point, so already costing me some £100 in wasted electricity!

I have a Sony TV too and I know that did all manner of tricks to pass the EU 1.5W directive, constantly disconnecting from the network and reconnecting once per 5mins, and gives a warning if you connect an amp to it that standby power usage will increase, so thought maybe they intended similar in the amp but failed.

I did do one complete master reset and got it back to 1W draw in standby, but as soon as I use any of the network services it permanently switches to drawing 30W in standby, 60W when 'on'. (So better than before the master reset, but not as good).

@mirrormurr do you have yours connected to the network via wired erthernet or Wifi? I did read some people find the wifi connection is lower power (BUT it disables all Chromecast / remote streaming function when in standby). I've not been able to recreate that though.

(Also, many thanks for sharing your encounter with attempting to get it addressed)

> Now I am actually wondering if this device actually should be allowed sold on a European market, as it must be in violation of all kinds of EU-regulations.

I definitely agree. There's numerous independent reports of this on different forums now. I also think What HiFi should strike it from the best-buy list, and moreover start measuring standby power consumption as a matter of course as the network AV receivers are increasingly going to be "always on" devices and the sum of wasted energy across all the devices sold doesn't bear thinking about.

mirrormurr — Wed, 04 Nov 2020 14:45:38 GMT

An old thread, but I realized the latter post deserved an update. Any network standby keeps consumption around 30 w. Bluetooth standby measures around 1.5 w. The new firmware has somehow messed up Chromecast and Bluetooth receiver-functions, though.

Re: str-dn 1080 stand-by high power-consumption

grolschie — Wed, 04 Nov 2020 18:54:19 GMT

New update uses the same 30w to 31w on Network Standby for me. No problems with the built-in Chromecast for me. Maybe do a factory reset - it solves as multitude of problems.

Re: str-dn 1080 stand-by high power-consumption

mirrormurr — Tue, 01 Dec 2020 18:20:39 GMT

A factory-reset did the job, the receiver now ticks like it should.

I also have a slight impression that the Chrome-cast-part of the system reacts slightly faster, although it might be the expectation-bias playing with my mind...
