low-power televisions?

[castiron]

Our current television is an old CRT that's doing just fine with a converter box. It produces a lot of heat, though, and presumably is drawing a fair amount of current.

If your main criterion for a television was minimal power consumption, what kind would you get?
(Yeah, yeah, "no television" is the optimal solution to that one.) LCD or LED, or wait for something else coming down the road?
