I used to be fairly aware of what an LCD television's pros/cons were compared to a plasma but these new super flat LED televisions seem to be the best of both worlds. Can someone out there explain to me the pros/cons of the LED tvs compared to LCD/plasma? Thanks!

LED TV Technology Pros and Cons
by Robert Wiley

PROS

The viewing angle on LCD Televisions with LED back lighting has improved dramatically to plasma-like levels of 75 degrees with no contrast level degradation on some of the best ones.
The black levels on the best new LED TVs has improved to plasma like black levels while contrast levels still lag the best plasmas buy hundreds of post calibration points
Brightness on LED based LCDs is better than the traditional flourescent bulbs
LED TVs will have better consistency of color information over time than traditional LCDs
LED backlit Televisions should in theory have a better lifespan than traditional LCD TVs or plasmas.
CONS
LED TVs with local dimming use more energy than traditional LCDs. It's not much, about 100W for a particular size range.
LED Televisions with discreet backlighting can have lots of dimensional depth to the cabinet. We recently reviewed one with a 6" depth to the cabinet â making it less wall mount friendly.
LED TVs are quite a bit more expensive than traditional LCD TVs. See our article titled "LED TV â Is it worth it?" or our "LED vs LCD" coverage.

What is the average lifespan of an LED TV viewed under the following settings?

I watch a ton of Blu-Rays, HD cable and video games kn mh Samsung 46" LED TV. It is now over a year old. I run it about 4-5 hours a day, backlight set to 7, brightness at 40, contrast at 100, dark levels at darkest. These settings look outstanding with what I watch and play.
Based on these settings, what would the approx. lifespan of my TV be?

Answer
Most tv in the market today are rated at 60,000 to 100,000 hours before they go half it's brightness. This also depends on the brand that you get. Any bargain price tv are not very reliable. Go online to Home Theater Magazine and read the reviews on tvs along with the pro and con of each technology. You will notice that Panasonic dominates the list with a Plasma tv. In November issue of the magazine it named the Panasonic Plasma tv model VT25 as the best tv for 2010. If you read yahoo questions, you will notice that 95% of tv problems comes from LCD tv and 95% of those are the bargain price tv. Keep in mind, you get what you pay for. I still have my first Pioneer Plasma tv model 4330 purchased in 2002 and have had no problems (purchase price was $6,400). Hope this will help you out.
