Buzzing heard when using the Oppo 105

[little wing]

Hi Folks,
I am hoping someone can help me.

I recently purchased my first blue ray player (Oppo BD105) my receiver does not support HDMI, so my connections are as follows: HDMI out of the Oppo directly to the TV. 6 analog cables out of the Oppo to my receiver for 5.1 sound. I am also using the dedicated stereo output for CD playback. I noticed last night when watching Skyfall, that during quiet passages of the movie I heard a buzzing. When I paused the movie and listened, the buzzing becomes audible from my listening position at about -25.0 db. The buzzing is heard from all speakers when my receiver is in Multi-channal mode. The same buzzing is heard from the dedicated stereo outputs. I tried moving the player as far away as I could from my receiver (about 6 inches) They are side by side. I tried a heavy duty power cord I have. I also tried separating the cables behind the stand as best I could but it is still somewhat jumbled. I have everything plugged into a Monster Power Center HTS 2000. Anybody have any ideas?? Thanks.

You did not have this problem previously or perhaps did not notice it? It almost sounds like a ground loop issue. A power conditioner will not prevent ground loops. It ONLY happens with the Oppo or if you disconnect the Oppo and leave everything else as is also?

I did not have this problem before I installed the Oppo. My last DVD player was a 10 year old Onkyo that I had connected to my receiver via coaxial cable. My CD player was a Jolida, and the CD input on the receiver was dead quiet with nothing playing. I purchased the Oppo to replace both units. I hear the buzzing now when the Multi-channal or CD input is engaged on the receiver, even if the Oppo is powered off.

What do you use for TV? I know I had a nasty humming and buzzing noise and it turnout out to be from my cable line. That's usually a pretty good place to start if you have one of those. The humming and buzzing is there no matter what as long as there is power to the thing powering your speakers (receiver or amps).

My TV is the Sony HX850. I have a Comcast cable box. Hdmi out direct to TV and coaxial out of cable box to receiver.

Try unscrewing the incoming cable line (the one that goes into the cable box) and see if that removes the noise. If so, that would be good and bad. Good in that you've identified the cause, but sort of bad because it means you need to buy a jensen transformer TRD something or other. If this doesn't help with the noise then it means you have ground loop hum and you'll have a lot of plugging and unplugging to do.

Looks like I got some work cut out for me tomorrow. Thanks! I appreciate it!

Btw, I'm not sure if you know what I was talking about, but the Jensen thing is small, costs about $50 and takes about 45 seconds to install.

Thanks, no I was not aware of this. Is this device installed between the cable line in and the cable box?
