Hi,

After doing all this troubleshooting on your receiver, Check if master volume on the surround levels are too low. Adjust master and surround level.

There may aIso incorrect selection of the input source. Select the correct input source.

If after doing this the problem still continue, it means the sound ic in the receiver is damage. the sound ic brings out the sounds from the receiver. You will have to open the receiver to locate the sound ic in the receiver and use the multimeter to read capacitors and change the damage ones.

Thanks for using Fixya.
