Why is there no sound from my Sony Stereo Receiver?
If you're not getting any sound from your Sony Stereo Receiver, make sure both the receiver and all connected components are powered on. Check that the MASTER VOLUME isn't set too low (at –? dB). Ensure the SPEAKERS ON/OFF setting isn't set to OFF. Verify all speaker cords are correctly connected. Finally, press MUTING on the remote to disable the muting function.
What to do if there is no sound or only a very low-level sound from Sony STR-DB780 Stereo Receiver?
If you're experiencing very low or no sound from your Sony Stereo Receiver, start by checking that the speakers and components are securely connected. Make sure you've selected the correct component on the receiver. Also, ensure headphones are disconnected and the SPEAKERS ON/OFF setting isn't set to OFF. Press MUTING on the remote to cancel the muting function. If a short circuit has occurred, the receiver's protective device may have been activated. In this case, turn off the receiver, resolve the short-circuit issue, and then turn it back on.
