TV power consumption/longevity
by KeraptisBlah - 9/9/12 4:04 PM
So my dad's birthday is coming up and I figured it's about time my parents get a high def tv. They don't have a lot of money (hence still having an old standard def tv), so I don't want get them something that's going to have much/any impact on their power bill, especially since their tv is running almost non-stop (usually fall asleep with it still on).
Conventional knowledge is that an LCD or LED screen would be the best bet here, but when poking around I noticed several plasmas in my price range like the LG 42PA4500, Samsung PN43E450, and Panasonic TC-P42X5, all with energy guide stickers suggesting $14-$17 annual power usage - very competitive with similar-sized LCD/LEDs!
So my question is twofold. First, are those estimates realistic? Has there been some recent breakthrough in plasma technology that has drastically reduced its power consumption? Or are they using some parlor tricks like turning the default brightness way down and in reality it'll be substantially more? And second, given that the tv will probably be almost always on, are there concerns about longevity with plasma vs LCD/LED?
Thanks for your help!
