Why is there no sound or only a very low-level sound heard from my Sony Stereo Receiver?

  If you experience no sound or very low sound levels, first check that all speakers and components are securely connected to your Sony Stereo Receiver. Ensure that you have selected the correct component on the receiver. Confirm that the SPEAKERS selector is not set to OFF and that headphones are not connected. Press the MUTING button to cancel the muting function. If these steps don't resolve the issue, the protective device on the receiver may have been activated due to a short circuit. In that case, turn off the receiver, resolve the short-circuit, and then turn the power back on. If the sound is just very low, verify that NIGHT MODE is not activated.

  If there is no sound from your Sony Stereo Receiver, ensure that the receiver and all connected components are turned on. Check that the MASTER VOLUME control is not set at its minimum (–? dB). Verify that the SPEAKERS switch is not set to OFF. Make sure all speaker cords are correctly connected. Also, press MUTING to disable the muting function.
