Power Consumption (8.76)
When checking for power consumption we adjust the backlight of the television until we get a peak brightness of 200 candelas per meter squared (cd/m2). At this setting the JVC LT-42P300 used an average of 125.33 watts, which works out to an annual cost of $24.75. This is for five hours of television viewing a day using the national average for energy cost. We should also note that unlike most HDTVs the LT-42P300 also draws a trickle of power when the television is turned off, although this didn't make a huge difference in the final cost. We als ran our testing with the backlight turned up to maximum and down to minimum. You can see all of our results in the table below.

The JVC LT-42P300's power consumption is significantly above average for all televisions, and is as good as or better than even smaller HDTVs, as you can see below.
