Is that really a lot in the scheme of things? I don't have CFL backlit LCD TV info handy since they've been supplanted by LEDs, but I looked at Best Buy (a big US seller of these sorts of things) and found a popular $500 65" and their most insane 98" $15,000 Samsung ones, 190 and 360 watts respectively.

I'm old and by my family's standards 65" diagonal would be questionable at best, so I checked in the vicinity of 48", 43" and 50" only gets you down to 120-5 watts. Add probably not very many watts for whatever's supplying the signal and it doesn't sound like a big deal, although of course everything adds up.
