Power Consumption (7.65)

Not surprisingly, given that we're dealing with a 52-inch HDTV here, the Sony Bravia KDL-52V5100 consumed more power than the average television in our testing. Our estimate is that the annual cost of operating the KDL-52V5100 for the average family will work out to $47.06. This is with the backlight turned down to setting 6 so that it emmited about 200 candelas per meter squaared (cd/m2) of light. This is the standard at which we test all HDTVs. Below you can see what happens if you turn the backlight all the way up (as we do in our calibration process) or all the way down.

As we mentioned above, the Sony Bravia KDL-52V5100's performance in this test is slightly below average. Below you can see how it compares to three other HDTVs. You'll note the major outlier in this grouping is the Samsung PN50A760, a Plasma HDTV. Plasma televisions usually draw much more power than their LCD counterparts.
