Please log in for more thread options and some not-so-great things about Plasma units though. Is there anyway to determine how much a specific unit has been used/viewed... for example... do any particular brands/models have a built-in, unmodifiable timer that can be selected from a menu to show how long the unit has been on over it's lifetime?... Any other suggestions would be greatly appreciated as well! TIA, Chip | |||||||||||||

Recently, several manufacturers, most notably Sony and Panasonic, have begun to claim that their newest plasma display panels now have half-lives of 60,000 hours. I, for one, am a bit skeptical of such assertions, if only because this would represent a 100% increase in the life of the product. While I realize that much is being done to increase the life spans of plasma TVs (such as increasing the resiliency of green phosphors), I'll believe these figures when I see them achieved in real life, not just theoretically. From the consumer's perspective, though, the 30,000-hour figure should be comforting, since this is about how long CRTs last. Let's put all this in perspective: Assuming the average American household watches 4 to 6 hours of television per day, a plasma display will last between 13 and 20 years. If you think about it, that's quite a bit of bang for your buck." | |||||||||||||
