Is it true that plasma Tv's deteriorate over time, and if so what is the life expectancy?

Question

...also what can be done to slow or reverse this?

Answer 1

check out this webpage...its a plasma tv buying guide and this page tells life spans of tv models and such. also has "saving tips."

here is part.

Plasma TV life span expectancy has long been a hot topic and rightly so. Most early plasma monitor models from 1999 and early 2000 have already been delivered to the electronics graveyard.

However, improvements in the longevity of plasma TVs and displays have been rapidly effective. The green phosphors are claimed by some manufacturers as the reason behind the incredible increase. Lower power usage and motion adaptive anti burn-in technology are also contributors.

In fact, many plasma manufacturers boast a life span of 60,000 hours to half life! This is a longer life than a tube based television. The specification is somewhat suspect since the process of determining longevity of the product is based on deductive mathematical calculation of phosphor dissipation, and does not take into account the electronic components and the myriad of problems that can occur. Panasonic was the first to claim the 60,000 hour life span, up from a previous 30,000 just a year prior.

Panasonic: States in new specifications that new plasma TVs and monitors are good to 60,000 to half life.

Sony: Now out of the plasma market. Does not list a figure for LCD lineup.

Samsung: Lists 60,000 hours for plasma lineup.

Pioneer: States 60,000 hours of use in their new 2005 models.

Sharp LCD panels: States 60,000 hour life.

For consumer use these numbers should be comforting. Plasma Displays are now about equivalent in longevity to LCDs, which typically state 60,000 hours. Consider that these figures are a great amount more than old CRTs, which regularly post life span to half brightness at 25,000 hours. Let's put these hours in perspective. The average U.S. household watches 4 to 6 hours of television per day. Staggering. Taking a mean time manufacturer stated longevity of 50,000 hours of usage, times our average 5 hours per day, calculates to over 27 years of usage.

Now, there are varying degrees of phosphor ignition along the way (the same way a CRT fades). Dissipation begins the moment you turn the set on. After 1000 hours of usage a plasma monitor should measure around 96% of its original brightness, which is barely noticeable to the naked eye. At 15,000 to 20,000 hours the monitor should measure around 80% brightness, or to state is technically, 80% of the original phosphors (gases) are being ignited.

Answer 2

After about 16 years.

Answer 3

it is true.....depending on it's use the color will begin to fade to a point where it's noticable from 2 years (with constant use) to about 4 or 5 years.....kinda expensive for a product with a short lifespan...if you're looking for a tv 42" or under you should go with an LCD tv if a flat pannel tv is what you're looking for...anything over 42" you want to go plasma.

Answer 4

Over time all items tend to deteorate but it's more common for plasma television monitors to do this due to the usage of the gasses and the burn in effect which plasma causes.

Answer 5

Not anymore. It will easily last 20 years.
