LCD vs. LED

[Blueface]

My 32" Samsung LCD in my bedroom is taking a fit.
Some shadow like lines/markings are showing up on my picture that appear to be permanently burned in.
At times it is becoming annoying so I have been looking around to replace it and just go bigger to a 40".

I recently saw the LED version of mine and the image is unreal as compared to an LCD. Not to mention the TV is supposed to be much more energy efficient and is practically just slightly thicker than paper.

I am a member of Consumer Reports and searched but can't find too many LED models and can't find the Samsung 40" I am looking at.

Anyone know if aside from a much better picture, if LED is more reliable? I can't phantom buying another TV for over $1,000, to see the price later drop by 2/3's, to then have it break down. I guess that is what modern technology is all about.
