Hello, Please reply back with what is connected to the receiver for sources (DVD, TV, Cable Box, etc.), and is there no sound regardless of which source you select?
Also, what is the brand and model of the speakers you're attempting to connect to the HK receiver?
Lastly, if you select the built in FM tuner- is there still no sund (not even static) coming from the speakers?
Please reply back and we can proceed.
