Question about Harman Kardon AVR 340 Receiver
I have a new unit that was bought on a buyout not sure if warranty would be avaialble. It appears to be a simple problem with the unit. The unit comes on and the display appears to be normal but when the amp comes on the speakers are hissing or sounds like a radio station without an antenna. No matter what input you select the sound output is the same.
I have the same problem. Only one speaker is hissing and only for analog sources. No hissing when I select Coax.
