LED vs. LCD: Save Energy with a LED TV

I live off-the-grid. A couple years ago, we purchased a Sony LCD television, and we were shocked to see the amount of power this TV actually used. It wasn't a huge set, but it did pull a lot of juice out of our batteries. When we had the opportunity to try a LED TV, we wanted to see if it actually did use less power.

We tested out a VIZIO TruLED. According to the manufacturer:

VIZIO's Eco HD models exceed the current Energy Star guidelines by 56% below Energy Star 3.0, which saves you money on your utility bills while limiting the impact on our planet.

In addition to the fact that LED HDTVs are more efficient than standard LCDs, the display's LED backlights do not utilize mercury, an environmentally harmful substance used in other backlights.


Some reviewers on Amazon have complained about the sound on the Vizio, and straight out of the box, I couldn't agree more. There was a strange sort of buzz and the volume needed to be cranked up for watching. The Vizio came set to "flat" in the audio settings. Switching this to "rock" fixed the problem.
 
Even thought this TV is larger than our TV, we noticed it uses less power. Obviously, that's a good thing for all consumers, not just those making their own power like we are. In fact, earlier this year California looked at regulating energy consumption of TVs.  LED TVs appear to be the solution, but I am not sure it warrants buying a new TV.  All of the energy and resources used in manufacturing a new set may not be offset by the energy savings.
