Hi David,
I haven't been able to confirm this elsewhere, but I've read on one site that "very early tube TVs from the 1950s produced (sic) well over 400 watts" (source: http://www.ehow.com/info_7795151_hd-tvs-vs-older-tvs.html). Today, a 42-inch Panasonic TC-L42D30 consumes just 91-watts.
Hoping for something even better? The LG 47-inch LCD HDTV reportedly consumes just 28-watts (source: http://www.electronichouse.com/article/lg_display_offering_worlds_most_energy-efficient_47-inch_lcd_hdtv/).
Cheers,
Paul
