The lifespan of a television: How important is it?

Wondering about the lifespan of your new TV? Should lifespan be a factor to influence your purchase? Get the deals and learn more!

What does “TV lifespan” even mean?

When we talk about how long a TV will last, or its lifespan, we’re really talking about how long the lamp inside it will last. Over time, the backlight in your TV will get dimmer. The lifespan of a TV refers to how many hours of use it will be until the lamp is half as bright as when it was brand new.


Is your old TV still working today?

To help lengthen the life of your television, lower the brightness levels. The lamps in a brighter TV have to work harder and will burn out sooner.

How long will your TV last?

TV lifespan varies between plasma, LCD and CRT televisions.

In the past, CRT TVs lasted the longest. As new technologies emerge and improve, the lifespans of plasma and LCD televisions are now comparable to a CRT TV.

When plasma TVs were introduced, they had a very low lifespan. Some lifespans were even as low as 8,000 hours of TV use. In recent years, plasma televisions have greatly improved and now boast a lifespan of up to 100,000 hours.

LCD and LED LCD TVs


How long will a new LED LCD television last?

Different brands and types of LCD and LED LCD televisions are marketed with a range of lifespan hours. Most LCD TVs claim a lifespan of 40,000 to 60,000 hours, but some go much higher.

Forty thousand hours is at the bottom of the range, but that’s still a long life for a television. Here’s 40,000 TV hours broken down. If you leave your TV on 24/7, its full brightness will last for about 1,666 days, or four and a half years. Most people won’t leave their television on nonstop. Let’s say you have it on for eight hours a day. With a 40,000-hour lifespan, a TV left on for eight hours a day will last for 5,000 days, or 13.7 years.

What about 60,000 TV hours? With 24/7 usage, the TV should last for 2,500 days, or 6.8 years. At eight hours a day of TV time, it will last for 7,500 days, or 20.5 years.

Verdict: Your LCD television should last for years – or at least until you’re ready to upgrade to a new one.

Plasma TVs claim a 100,000-hour lifespan


A plasma TV should last you for years, so make your purchase count.

With the upgrades in technology, plasma televisions generally have the longest lifespan now: as much as 100,000 hours.

At minimum, a plasma TV with a 100,000-hour lifespan should last for 4,166 days, or 11.4 years. If the TV is on eight hours a day, its lifespan is 12,500 days, or a whopping 34.2 years.

Verdict: The lifespan of a TV is a good thing to consider when you’re shopping. But, will you really want the same TV still in 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 nice to know.

Shopping based on TV lifespan?

How important is TV lifespan? It depends on your plans and what type of TV you’re buying. As technology keeps improving, televisions last longer and longer, so you can buy with confidence.
