All,
I've recently been getting a hum/buzz through my home theatre system. When I installed it early last year everything was fine, no noise. Recently I have noticed a hum. Originally I thought it was a ground loop. So I did an isolation test. No change. I also tried a new PowerPoint via a extension cord with everything connected from my home theatre to it. Noise still there.
The loudness of the hum is becoming unbearable to a point where I have to turn the volume up to drown out the hum. Which is no good at night with the bub asleep.
I have also noticed sometimes when I turn my receiver off and leave it off for a minute or so. When I switch it back on the hum is very slight and barely noticeable, unless I put my ear to the speaker.
With all this in mind I believe there is a fault somewhere in the VSX-920k, something inside is causing this hum through the speakers.
Thoughts?
