Volume decreases by itself - tx-nr808

My avr has just started to decrease the volume from my setting (last 24 hrs only, to my knowledge). I start it at 50 and then it slowly goes down to 0. All remotes have been removed from the room so it appears to be the Onkyo itself. I've only had the unit for about a month and the D. equaliser and D. volume have never been switched on (I'm still installing speakers; 2 more to go to a 5.1 system). Reading the manual, D. vol would appear to be the only thing likely to set a change in motion. Would you advise pls. I have not updated the firmware since purchase. That is next on my list but am loathe to do so just now due to this issue perhaps interfering. No settings on peripherals have been altered in the last 24 hrs.

I did a factory reset and the problem still occurs. In addition I note that the Master Volume on the unit does not respond either. This is the first time I've tried the master volume as I have always used the remote for volume changes.

Pls - any assist

Hi Peter,

This sounds like it may be an issue with the receiver. Please contact our product support department at 1-800-229-1687 option number 3 for further instructions with your issue.

Hi, thank you for your previous reply. I didn't mention it earlier but I live in Brisbane, Australia. I did try and phone your number during your office hours but you had a holiday on Monday and on Tuesday I only got as far as the recorded message. I didn't stay on for long as it is expensive. Would you be able to have the appropriate support people contact me by email at the address in my profile.

I know this may take a bit longer but the unit in question still provides entertainment despite the issues it exhibits.

Thank you

Peter

Hi Peter,
Where did you purchase your unit?

Hi, I purchased it locally in Brisbane from Sunnybank HiFi.

Peter

I found this at another site OnkyoUSA (I don't know if that is yours or not).

My problem sounds like this; especially as mine has extended its issues to the following:
1) The source switches automatically through vcr to cab to dock and back again (why dock I don't know, never used such a thing)

2) Remote use receives no response at receiver

3) Master Volume no response

4) vcr, cab buttons no response although hitting standby button invokes factory reset

5) Unit switches it self off and on

6) Now almost unusable, problems recur too frequently now

Hope to hear from you soon

Peter

Hi Peter,
Yes, that is a press release from us, but we are Onkyo USA and you purchased this unit in Australia. Here is a service center that may be able to help you out located in Australia, but unfortunately, we only deal with the US and Canada here: http://www.intl.onkyo.com/support/local_support/australia.html I hope this link helps you out. Thank you for choosing Onkyo.

Ok for that. However, I would like to know the nature of the fix pls. Some detail on software/hardware/replacement method used to fix the issue. I think that info would be of use to me from here on in, dealing with local support.

Thanks

Peter

Hi Peter,
I am, unfortunately, not a technican so I do not know the answer to your question. Product Support is meant to troubleshoot the issues, we don't actually go into the hardware of the receiver. Also internal specs may vary from country to country. Since the information in the link I gave you is an authorized service center they should be able to help you out with all the information you need. I am sorry for any inconvenience this has caused you.
