HK 7200 Unexpected Volume Increases

I was moving cables and adding banana plugs and now my HK experiences occassional volume increases. Volume will jump from -35db to -19 or 0 with no contact to the receiver or remote. Has anyone else experienced this?

I'm assuming its a contact problem with my cables but I thought I read something about this a while back. Anyone?

Thanks

I have not expericed that or read that before. I have changed a lot of cables around too. If you were messing with digital inputs, could it be jumping to a remembered mode with cranked speaker settings? Let us know what it is when you figure it out.

Also do you have any other remote device that could be interfering with the 7200? Or could the batteries in the remote cause it to do something weird? Was it facing the receiver when it happened? The batteries that shipped with my 7200 remote were no good.

NC AV Man, thanks for the response. Here is a thread with some others having the issue.

I'm going to try a few things tonight to reporoduce or eliminate it. Dont think any remotes were in the vicinity.

Thanks for the link. I think I would jump out of my skin in my AVR went to 0db. I have very efficient speakers with powered woofers (94db), if the AVR went to 0db by itself it would be deafening. Let me know if you figure out what might have caused it.

I will keep you posted. It's so sporadic it may be hard to pin down. I reset the receiver yesterday and it hasnt happened since. I want to play around with "Surround Off" because this is the mode it seemed to occur in.

Interesting response from Harman Kardon:
>>>
Thanks for your inquiry to us. We have not seen this with the newer receivers...However, if there are any florescent lighting in the room with ballast (e.g. small lamb energy saving bulbs). We have seen them interfere with the receivers and sometimes causes the volume to ramp up without
notice. This issue is very random and if you find the symptom occurring quite often the problem may be microprocessor related and it should be
checked out by a service center.
Hope this helps.

I do have energy saving fluoruescent bulbs in the adjacent room within site of the receiver. I wonder if there is something to this. It hasnt happened since I reset the receiver. I prefer the static electricity explanation since the receiver is sitting in the bottom of my old rack which I was sliding across the rug to reconnect cables.

Hmmmmmmm...

Just an update. It hasn't happened since. I have to believe it was static electricity from sliding my old rack across the rug while moving cables.

KidA - That's good to hear. Let's hope that was all it was. If you ever see anything else strange though let us know. I am still seriously enjoying this AVR more and more every day.
