Vs Samsung LN40B650
Power Consumption Summary
• The LT-42WX70 would cost about $21.83 a year to run
• With the backlight on maximum, that would rise to $32.13
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.
| Setting | Average Watts | Cost per Year |
| Backlight +10 | 111.6 | $21.83 |
| Backlight +30 | 164.4 | $32.13 |
| Backlight -30 | 55.1 | $10.79 |

Samsung UN32D5500 LED LCD HDTV Review
The D5500 has a rather high MSRP of $699, considering it’s only a 32-inch TV. There are some “premiums upgrades,” a term we use with some dubiousness, knowing that these features can be far less valuable than they appear. Nevertheless, at its core this is a good television. If you can find it a significantly reduced price it would make a great addition to a home theater. Read More...
