Chosen Solution
When all hooked up properly, I have no audio coming out of the speakers, can only hear a buzzing/hissing sound from all the speakers. It doesn’t matter which input is selected, they all have the same issue. Even before selecting any input at all, you can hear the buzzing/hissing as soon as the unit is powered up. Any help would be much appreciated.
Go through the diagnostics section of the service manual here. You can start at “Step 2: Power Supply”. Let me know where you get to.
