New TV / Loud whining sound from external speakers when turned off

First of all, you bought a low end quality TV set. As far as making modifications to the set, it would not be feasible. Most of the lower cost models lack the refinements of a high end set.

Try out the middle or upper end of the models from Sony, Panasonic, Hitachi, and JVC. You will find a big quality and performance difference.

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?

I have no intentions of modifying any TV. Samsung was not my first choice, but I wanted a flat screen CRT TV, not a LCD or Plasma, and my choices were limited. This TV is in a bedroom and 20" is the maximum size, plus I wanted one with a headphone jack so I could use my HK695 speakers, so it was JVC or Samsung. I bought a JVC first but found that the JVC site had misrepresented the model and some features listed were actually only on the larger models. (Features like BBE audio, which were on my previous JVC 20" and mysterisouly missing from the new model.) From what I could tell Sony and Panasonic were no longer making CRT TVs.

I'm just trying to get an idea if exchanging the Samsung would improve the loud audio whine in the external speakers when I shut the TV off or whether it sounds as if there's something in the design of the model that would make an exchange a waste of time.

Most all the lower end models of the price range or the CRT sets will have the problems you are describing. To put it simple, the scan amplifiers, and the power supply radiate some electromagnetic radiation. There is an added cost to design circuitry that will have a high degree of isolation for noise (Radio frequency or electromagnetic radiation) between them.

With today's technology, I personaly would never buy a CRT set. You get a much better set with a much higher degree of performance for the cost in the LCD or Plasma types. You pay a little more, but it is worth the difference.

No LCD or Plasma gets near the performance of a good CRT. You've been conned by the advertisers.

When the set is off, you say.

Since in another article you mention the possibility of exchanging the set, I'd check with the store. Try this: plug headphones from a portable stereo into the set while it's off and see if you hear the whine through the headphones. If so, take them to the store where you bought the set and try a floor model.
