Televisions: 4-6 years
With the rapid changes in the way video is transmitted to your TVs and the ever-increasing resolution jumps (4k-8k-16k!), TVs start to show their age around the 5-year mark. Time to failure is typically 8-11 years or about 50,000 hours of use.
The generally accepted method for measuring lifespan is the number of hours of use until the TV is half as bright as it was when new ("half brightness"). The TV is still watchable, it's just not as bright.
