What is the average lifespan of Plasma TV?

When I used to sell TVs, manufacturer's claimed 30k hours, eventually Panasonic claimed 60k hours. But until plasma is left on for 6.8 years (60k hours 24 hours a day)... how can anyone know for sure? I saw a few fail on the showroom floor. Many were sold, a few came back, it's like any other electronic... they last 3months to 10 years, there are no guarantees.

until a wiimote goes through it

around 60,000 hours,of course theres other factors involved like leaving the tv on all the time, but of course that is rare so is around 50,000 to 60,000 hours

when I went to buy a plazma I was told that panasonic's now can last over 20 years

I've heard a few years.

Minimum is 15 years and the maximum life span I can say is 25 years. It all depends how it is maintained.

well mine about 6 months haha. it was a dell and didn't last very long at all. So don't get a Dell.

5 years

3-4 years so you end up also with a high end electric bill as well, so it will cost you an adverage of 20-30 a month to own one an extra 10 on the payment for electrical use if there bigger then 30 inches
