If the unit is under warranty, DO NOT open it up. Bring it in for an exchange or warranty service. Explain that the unit makes noise during use and it will be serviced. This could be as simple as a bad connection in the power supply area and you are hearing oscillations or it could be a defective power transformer. Either case will be covered under warranty so there should be no charge to you.
