How long does a TV set last?

Television is one of the necessary household appliances in today's family. There are many brands and models of TV sets on the market. So how long can a TV set last? Which TV has the longest life?

The life of a TV set is generally calculated by the hour. The life span of traditional CRT TV is 20,000-25,000 hours, which is only theoretical data. At that time, TV was one of the four necessities for families, so every family cherished it. It's not fresh after 20 years. Even the TV box takes a long time, almost as long as the TV. It's on almost every wardrobe.

The screen life of plasma TV is 40,000-50,000 hours, but the popularity of plasma TV is very short, and the price was very expensive at that time.

LCD TV has a life span of 60,000 hours and is the most popular TV set at present. The most popular one now is curved.

At present, China is formulating the national standard for the safe service life of household appliances, that is, determining the actual service life of household appliances from the perspective of safety. In other words, enterprises should ensure the actual service life of household appliances for the sake of consumption safety, and should scrap them after reaching the service life. It is preliminarily determined that the minimum safe service life of TV sets is 12 years. If the technical level of the enterprise is high and the safe service life of the product is longer than 12 years, the safe service life of the product shall be clearly stated in the appliance or instruction manual.

The service life of a normal LCD screen is generally around 50,000 hours. Suppose we watch it for 6 hours every day, a screen can last at least 22.8 years. If the hardware and sound system of a TV are kept at a backward level through extensible split or modular design, then the service life of this TV can be greatly extended. If you are an enthusiast who doesn't pay much attention to display technology, then split TV is definitely a good choice.

At present, the average service life of LCD TV sets is eight to ten years. In contrast, there are refrigerators. According to the national standard, the safe service life is ten years, air conditioners are twelve years, washing machines are twelve years, electric water heaters are six years, and so on. In a word, they are not as durable as you think.

Back to TV, in fact, the size of flat-panel TV is positively related to power and calorific value. The larger the size, the greater the power and calorific value. Therefore, in order to prolong the service life of TV, we should put it in a dry and ventilated environment.

If the picture of TV picture tube is not clear and the picture is trembling, it has already shown that the related components are aging, not only the radiation increases, but also the explosion may occur when it is hot or cold.

Some people may say that my TV has been used for more than ten or twenty years, and it is still no problem. It should be noted here that this is only a theoretical value. For example, TV is most afraid of uncontrolled switches. Every time the CRT filament is turned on, it will preheat, which will accelerate its aging, but it will be well maintained and can be extended. It's just that its best service period has passed, and it may stop working at any time, just like the next year.
