Question about Harman Kardon AVR 500 Receiver
Of late I have been getting an annoying hum on the RLC channels of AVR500. The SRSL channels seems to have no hum.
I have replaced the power strip with a high quality Belkin power strip
I have removed all the input sources and it still appears
When switching from source to source, the hum disappears briefly
I have uncoiled all the wires and laid it out straight
I have tried grounding the unit properly
I have tried grounding the Black terminal of the speaker
I am willing to open the Revceiver and replace any parts myself if I have enough info to try it out.
