Think my new x4500h may have a minor fault
I'm getting a faint hum in just the left surround channel. Can't really hear it from normal listening position, but notice it every time I walk past the speaker at ear height when volume is down / surround off. Have tried unplugging unnecessary inputs, sub etc but still there. Swapped surround speaker connectors on the amp and it showed up in the right surround so its not the speaker / cable. Doesn't change with volume or mute but seems to disappear if I turn eco off. Would rather have eco on auto to keep everything cool.
I could live with it, but if its faulty would rather get it sorted. I assume this isn't normal? Some sort of grounding issue between the eco power supply and left surround channel?
