BDVN7200w High Pitched noise

[rosgaly]

Hi,

I was wondering if anyone one else is having the same thing. Recently bought the all in one BDV N7200w suround sound system, and everything works as it should however, the Amp that powers the rear surround speakers makes a really annoying high pitched whine when I turn on the main head unit. Even if theres no content playing through the speakers the whine is there and you can really hear it durring the quiet scenes in a film for example.

I have tried different sockets to see if its maybe that particular socket in the room is cousing the noise but its the same in every socket.

Is there a solution for this or is my amplifier faulty?

Many thanks!
