We had bought the set as a complement to our Sony Bravia KDL-40EX525 and the initial enthusiasm about the aesthetic look of all components and the amazing 5.1 sound was gone within seconds, because the unit is continuously a very loud whistling sound by itself. It sounds like the typical condenser pipe, which one knows of cheap or defective capacitors and is a real teeth on edge -. And finally belonging to the nerves
There is the Internet a series of reports on this issue, and apparently there is no repairing it. We have also in various local electronics stores different versions of this set tested (790, 590, etc.) and all fiepten!
Certainly that is a question of the distance to the unit, the individual spatial textures and ultimately ensure also the private hearing, but we found it intolerable and are totally amazed that you sold these devices as simple. So if you have sensitive ears, should think twice about buying this product!
