The lifespan of a TV backlight depends on the type of TV and how much you use it.
LED backlights usually last 4.5 to 6.8 years when used at maximum or near-maximum brightness (40,000 to 60,000 hours).
If you use lower brightness settings and use the TV moderately, they can even last over 10 years, reaching up to 100,000 hours.
LCD TVs, which also have LED backlights, typically last about 5 to 10 years, while plasma TVs last around 5 to 7 years.
The industry standard for LED lifespan is 100,000 hours or about 10 years, but how long your TV lasts can be affected by factors like brightness settings and how often you use it.
With regular use and proper care, many TVs can easily last over 10 years.
