PS3 ground loop?

1414 Views 3 Replies 3 Participants Last post by  S Varney
Hello, hopefully someone can help. In my theatre I have a PS3 (original model) in a system with an Xbox 360, Pioneer 82TSX receiver, Parasound amp and a Panasonic AE4000 projector. The PS3 is connected via HDMI; the Xbox by component. Note, there is no cable or satellite in the system though there is a wifi access point and switch. All are on same circuit.

When the PS3 is turned on, buzzing sound through all speakers. If I unplug the HDMI cable, no buzzing. Could this be a bad cable (don't have another to test with)? Or could this be dreaded ground loop, even without cable or sat?

Is the buzzing sound low frequency (60hz)?
The cheapest, easiest way to find the problem is to first try a different hdmi cable.

No, I would say it's midrange. Should also add that, as far as I can see, there's no video issues.
