Have you wondered; how long do Tv’s last?

Back in the days of cathode ray tube televisions, a good, sturdy set from a respectable manufacturer could easily last 20 years.  In the late 90’s, plasma display technology matured enough to make it a viable commercial TV option. Although prices were initially very high, they dropped steadily over the next few years and by the middle of the first decade of the new millennium they were also an affordable option. However, this older generation of plasma TVs had an expected lifespan of 20,000 to 30,000 hours, or even less.
The most significant problems were those of screen-burn-in and reduction in the intensity of the image over time as the gas “wore-out.” Screen burn-in was the phenomena that a prolonged single image would result in a ghost of that image being “burned-in” to the screen permanently.
Actually this happened, though not to the same extent, even in other display technologies. Decreasing screen intensity was another problem too.

When flat-screen televisions first appeared on the scene, they drew upon relatively new and unrefined technologies, meaning high failure and defect rates. Over time the technology has matured. LED sets promise to be some of the most long-lived televisions on the market. It is an open secret that the latest LED/LCD/plasma TVs are expected to last only around 4 -5 years. Much has been made of the longevity of LCD TVs, at least compared to plasma TVs. The conventional wisdom is that LCD/LED televisions last longer than their plasma TV counterparts, which was true.

LED televisions are a special class of LCD televisions. They differ in that the older LCD technology uses cold cathode fluorescent lamps to light up the liquid crystal screen, while LED sets use thousands or millions of tiny LEDs, or light-emitting diodes. LEDs consume significantly less power than CCFLs. They generate less heat and don’t burn out nearly as quickly as CCFLs, meaning that LED sets tend to last much longer than LCD sets. Some manufacturers, claim that the actual LEDs in some of their LED television sets will supply approximately 100,000 hours of useful life. At six hours of use every day, that works out to approximately 45 years of service. In other words, it’s likely that your LED television will fail because of some other component instead of the LEDs themselves.

One must bear in mind that excessive heat kills electronics. Theoretical lifespan projections assume that you will keep your LED television well-ventilated and protected from heat sources such as sunlight, heating vents, lamps and other large electronics. To prolong the lifespan of your LED television, avoid these heat traps; keep the ambient room temperature between 25 to 30 degree Celsius.

Verdict: The lifespan of a TV is a good thing to consider when you’re shopping. But, will you really want to use the same TV for the next 30 years? Or even 10? Keeping these things in mind, the lifespan of a TV probably won’t have much impact on your purchase, but it is always nice to have this information at hand.
