Just measured mine. It fluxuates quite a bit depending on brightness, but it averaged around 75W. 1W when turned off. Its a 27" Panasonic flat screen (not flat panel).

160~180 watts with satellite receiver + DVD player.

All three of my (free) 19" CRTs are around 55-65W IIRC. My (free) 27-32" CRT TVs are around 60-85W and my 37" is around 95-100W. What really knocked my socks off was a brand new ($600) 42" LCD TV I just got. Turned off the back-light and the SOB uses ~65+W! It's freakin' huge, and uses the same amount of power as my 19" CRTs! Full HD and all that crap. Kind of a splurge, but daym HD look good, at ~20-50W (24/7 because there's no standby and I don't need my old VCR for inputs anymore) less too.

It's a shame the 360 is such a power hog.

I monitored my 30" widescreen CRT HDTV a little last night. I saw between 100w and 180w depending on brightness and aspect ratio of content. It was hard to tell if high definition content used more power than standard def wide screen.

My 20" CRT tv uses about 50w when turned on, 3w in standby. It's pretty consistent regardless of what's actually showing - TV show or static.

We had 27" CRT, used about 60-75W, 5W in standby. Plus sat+dvd+other gizmos we had about 25W going into the RTV cabinet when everything was off. So I introduced something called a "powerstrip with off switch". This was hard on Dad-in-law, he still often forgets to kill it when he's done watching TV late in the evening. Killing a 25W phantom load saves a lot, but...
One day the Wife and I come home and there is a 37" LCD. Uses 10W in standby, 180W when on. Since it's HD, Dad-in-law gets a new HD sat tuner, which also needs more juice, be it on or standby. This set-up pretty much kills any savings we would have had with the previous set-up. Wife and I still turn the powerstrip off whenever we can (I sometimes get up at night, go downstairs and kill it, since Dad-in-law didn't), but Dad complains that this constant switching on and off is bad for the electronics (plus it takes his sat a whole 30 seconds longer to warm up).
