Dear Frustrated,

Luckily, the problem is not your HDTV; it is the power being supplied to it, which is an easy fix. AC lines are contaminated by RF and EMI noise that affects the picture on plasma and other high-resolution TVs. When you turn on your new HDTV, this noise ends up masking much of the detail needed for the best possible resolution.

To fix this problem, I would recommend adding a power conditioner to your home theater, as demonstrated on the sketchpad. As you can see, not only will the picture on your TV be improved, but your system’s audio will be improved as well. As with video, AC noise masks detail in audio, and by adding a power conditioner you can get the most from your high-end speakers and amplifiers. As an additional bonus, all your connected equipment will also be protected from damaging surges and spikes.

Choosing the right conditioner is a little trickier, as they are not all the same. To eradicate noise, AC power must be properly filtered. Filtering means taking the noise present on an AC line and lowering it in level to such a dramatic degree, and over such a wide range of frequencies, that it cannot contaminate a signal being captured or reproduced. The majority of products on the market either don’t provide filtering or have antiquated designs that have not been linearized.

I would recommend Furman Sound’s low-cost Elite-15, which features Linear Filtering Technology™ (LiFT), a special Furman technology that assures even and consistent filtering for crisp, clear sound from amplification systems and intense visual displays. In addition, the Elite-15 offers Series Multi-Stage Protection (SMP) to clamp and dissipate damaging transient voltages without sacrificing itself, and Extreme Voltage Shutdown (EVS) to protect against accidental connections to 208 or 240 VAC.

Give the Elite-15 a shot and I’m sure you’ll be enjoying your new plasma HDTV in no time.
