Hey rkrone,
That's the dilemma I had. I picked up two .co's and didnt know what to do with them. Your keywords here are awesome as 3D LED tv's are the latest and greatest. I don't see why you couldn't turn it into a profitable site with some SEO and development work. I like the name personally, and .co's have been selling lately. You could flip this for low $xxxx if you ask me. SE's are treating .co's pretty fairly I have noticed, so it might be worth developing first, see how it does, then go for a flip as opposed to just flipping it.
Just my .02
