Consumer electronics/energy efficiency

I've researched this a bit and discovered that I can save quite a bit of energy by replacing my old CRT computer monitor and TV with similarly sized LCD monitors. My 17" CRT computer monitor uses well over 100 watts, while a similarly sized LCD monitor would use about 30. The savings with my TV wouldn't be as dramatic, but still pretty impressive: my 19" TV uses 80 watts, while a similarly sized LCD TV would use about 40. So it's obvious that replacing them would cut down on my energy consumption. But I'm wondering if anyone knows how manufacturing plays into it? For example, if I buy the LCD TV, and say it lasts 10-15 years, would the CO2 generated during manufacturing outweigh the savings from the TV itself? Assuming the TV is turned on for maybe 2 or 3 hours a day, over 10 years I would save around 8 or 9 kilowatts. Would that savings be enough to justify the purchase, in terms of carbon savings?

There was a similar thread about dishwashers recently, which branched out into other household appliances. It might be nice to consolidate this whole discussion.
