then what to do?

then what to do?

Check wether the power cable goes into the avr has 2 holes or 3 holes...if its 3 holes then call in an electrician and check the earth in the home socket. Try calling denon support too....rare chances of product itself faulty!

I guess some electrical device close to the rack is emitting some emf/rf which the transformer is picking up.

Humming noise is due to electrical circuit grounding issue or any electromagnetic field close to the unit. There are ferromagnetic beads available in different sizes on amazon. Apply those to the power cable of avr .this should cancel the noise

Disconnect everything including the tv from the power source and power up the Avr alone. See if you are still getting the noise
