Power Consumption (8.91)

HDTvs can be power hogs, with some larger sets costing up to a hundred dollars a year to run. So, we test how much juice every TV that we review uses, and calcualte what the typical running costs might be, including how much power they use while they are on standby, assuming an average of 5 hours of use per day. We found that the LT-42WX70 did pretty well here: we calcualted that it would cost a typical user about $21.83 a year to run at our standard brightness level. If you like to crank the backlight all the way up for the brightest possible screen, the cost rises to $32.13, and with the backlight on its lowest setting, the cost falls to $10.79 a year.

To adjust for the different screen brightness that we see from different TVs, our score is based on the screen being adjusted to a standard brightness of 200 cd/m2, which is bright enough to be seen indoors on a typical day. We also test with the backlight at the maximum and minimum settings so we can see the range of how much the TV costs to run.
