Yep, my 40" Samsung LED backlit TV is rated at 40W. To give you an idea of how much energy that is, the Samsung soundbar + subwoofer is rated at 180W. That's 4x more energy consumed (at peak) by the barely-midrange soundsystem than the display. It's 8x more than my 5W rated Amazon Fire TV (streaming media device),
but, running my electric oven for 20 min to make my pizza uses more power than my TV, Speakers and streaming media device do in a month.
Shrug. There are bigger, better fights to pick than LED backlit TVs.
