How long will your LCD/LED TV last?

November 2015

Most LCD/Plasma TVs last for a few years before problems such as loss of color, brightness, black spots begin to show. The life expectancy of an LCD/LED TV can be between 4 to 10 years depending on usage and maintenance as well as other factors such as type, brand, location and environment. Branded TVs from multinational companies such as Sony, Samsung or LG tend to last longer as the hardware components used in the TVs are more expensive and thus more reliable. In general, the life expectancy of an LCD or LED TV is a few years after the expiration of the warranty.

How long will your LCD/LED TV last?

Flat screen TV life expectancy!

According to manufacturers, a TV has a lifespan of approximately 40,000 to 90,000 hours (continuous use), representing between 4 and 10 years (active use). Of course, this remains theoretical.

In fact, these estimations do not mean much. The lifespan of your device will evolve according to its type, its brand, its use, its location/environment ...

The type of flatscreen


  • LCD: neon lighting
  • LED: LED lighting

Note that the cheaper a TV is, the harder it is to repair it. Indeed, the technology is much more complex than the plasma system.

LCD TVs use liquid crystal displays. These crystals (commonly called "Pixels") each reproduce a tiny piece of your image. Thus, their timings have to be perfect to render sharp images.
  • First issue: the response time. The device has a small "processor" that coordinates its activities (synchronize pixels) and over time, the images may show sudden streaks, color changes etc. In short it may be a real pain to recalibrate the image.
  • Second issue: although these screens are described as "tough" compared to plasma screens, they are not indestructible; the pixels, trapped between a layer of silicone and a layer of plexiglass may die (apparition of black spots).
  • Third issue (only LCD): LCD TVs are known for excessive brightness, but over time they may experience a drop in brightness (but's that not a big deal).

In contrast, LED TVs have no (or very little) related issues...

Plasma TVs

In a plasma screen, the pixel structure consists of encapsulated gas (phosphorus), trapped between two glass plates. By applying an electrical current the gas will undergo some chemical reaction, resulting in the creation of the "Plasma".

The plasma emits ultraviolet light which changes color upon hitting the phosphorus layer of the capsule.
  • First problem: loss of color. The radiation emitted by gases (especially xenon) tends to change (a natural phenomenon) because the chemical reactions are not always the same.
  • Second problem: loss of brightness. Same as with LCDs.
  • Third problem: fragility. plasma TVs are more fragile. Indeed, if the glass is damaged, the gas may gradually escape ...


Often, brands like Sony, Samsung or LG will last longer than most other brands ...
This is because these companies invest in more reliable components. However, they each have their flaws.
Please note that products of this type rarely last more than a few years after the warranty.


Again, if your screen is constantly turn on, it will quickly is to better turn it off (when not in use) than leaving it on standby mode.


The location of your TV is very important. Depending on where you place it, the life span will change:
  • Near a window, ... the sun will quickly warm up the (television) and may damage the components.
  • Near a wood stove: wood dust and ash, and the heat generated will really shorten its lifespan.
  • Too close to the ground: the dust will settle there.

If you can, mount it on the wall ...


Besides manufacturing defects that come with each TV, you can use it up to 5 years under normal operation (4/5 hours a day), before experiencing the issues mentioned above.
