I measured my TV's electricity consumption a couple of weeeks back. It's a 37" LCD. It uses ~160W at full brightness and ~80W at 50% brightness. It uses 7W when "off". I usally keep the power bar it's plugged into turned off (along with the settop, Wii, DVD player, etc.).

AIUI, there are newer energy star rated TVs that use 1W when off but spend about 25% of their "off" time time powered up and downloading channel guide data. The screen is off but the tuner is still fully powered. The one Sony model mentioned 20W of usage when grabbing guide data.
