Question about Harman Kardon AVR-630 7.1 Channels Receiver
I have a HK AVR 630 and everything powers up and functions perfect except I have no sound coming from speakers. I have tried all troubleshooting advise (Volume, mute, no headphones plugged in and etc). Any help would be greatly appreciated. Thank You

Ensure that your speakers are connected to the terminals that you have your speaker selector switch turned to.
Then check that you have your device, whether it be a CD or DVD player, or turntable, plugged into the correct input and that you also have the correct input selected on the receiver.

In my case the buzz was only on front speakers. There are 3 capasitors (100uF/25V) very close to the cooling ribs of 3 regulators in the power supply. In my case the C922 was bad.
