I was reading a review of the Samsung 63 inch plasma and I came across this quote... "Samsung claims a 1000:1 contrast ratio. I dont have a way of measuring this, but it does seem reasonable in comparison to other sets I have seen and their reported stats. About the highest I have seen claimed is 3000:1 by Panasonic, and their sets do seems to have great contrast. Industry conjecture is that Panasonic achieves this by driving their phosphors harder, which gains extra contrast but at the cost of screen life. A typical plasma TV has a life expectancy of 30,000 hours, but a Panasonic supposedly has one of 15,000 hours." Full review: http://www.revolutionhometheater.com/equip/samsung/index.html Is this true as I've never heard of Panasonics having half the life of other plasmas? If so, that's pretty poor.
