New TV / Loud whining sound from external speakers when turned off
I just bought a new Samsung 20" slimfit TV model tx-t2082.
I hooked a pair of external HK695 Harmon Kardon speakers to the headphone jack, as I have always done with any of my televisions, because I really like how they sound without having a fancy hookup. (These are powered speakers, with a sub woofer and two satellites.) Aside from being less than impressed with the picture (some bowing and blurring in the corners) there's a very loud whining sound coming from the external speakers when I turn the unit off. It varies in intensity while it's off. When I turn the unit on the sound is normal. These speakers work fine in any other TV I've tried, and I've used them daily in my JVC TV that needs to go out for repair. Does this sound like something wrong with this specific unit or something inherent with the design of this particular model TV? I didn't hear any whining when listening with headphones. This model has a red light in the front that lights up when the unit it Off and is not lit when the TV is On. (Opposite of what I would have wanted.) Could this have anything to do with it? Thank you- Vickie |
