How Long Should You Expect Your Television To Last?

Erick R Williams (2012)

The old-fashioned tube televisions that we used to buy could last 25 years or longer.  This is not the case for the flat panel display televisions of today.  These televisions use LED/LCD or plasma displays and these displays do not have a life of anywhere near 25 years.  We accept the trade-off of HDTV and very large screens for a shorter life span.  A rule of thumb has been five to ten years with plasma televisions at the higher end of that range.  Life-span also depends on how many hours per day your television is on.  50,000 to 100,000 hours of service are oft quoted as expected service from flat panel televisions.

Life span does not mean the time until your television ceases working, but, rather the time until your screen only reaches half the brightness that it did when it was new.  CRT (tube) televisions did not appreciably decrease in brightness though it was possible to get "burn in" if there was a stationary image that was left on the screen for a long period of time (in that case the phosphors were essentially burned."

Another variable is when you bought your television.  Recent improvements in technology has lengthened the life span of flat panel screens.  If you bought your HDTV, say, five or more years ago, you might expect five to ten years of service.  If you bought your HDTV in the last year or two you might expect 10 or more years of service.  Another variable is how many hours per day that your set is on.  Many manufactures base life span on five hours a day of use and that number seems rather conservative.

Recently manufactured televisions promise 100,000 hours of service.  You can divide that by the number of hours per day that you use your television to get the number of years that your set might last.  However, when you do that, you get very large numbers that simply do not make sense.  I would stick with five to ten years for an older set and perhaps ten to fifteen years for more recently purchased sets.

Good article! I didn't know that life span meant a reduction in brightness.

My New Haier lasted 15 minutes before it lost picture. Luckily, we were able to return it under warranty...although it took 45 days to arrive....

Most electronics fail quite quickly if they are going to. It's one of the reasons I am not in favor of extended warranties.

It isn't the screen that will go bad first.... the hardware ( power supply and motherboards ) that will go bad long before the screen brightness. and let's face it 5 years from now your new TV will not be worth anything anyways. So there isn't any reason to care, it is just like PC's, 5 years is all you need......
