What is the life of TV?

　In July 2011, it was completely shifted to "terrestrial digital broadcasting", and more than 10 years have passed.It is said that the useful life of TV is about 10 years, and from 2010 to 2011, some people who purchased terrestrial digital TVs are considering replacement due to breakdowns.I asked Mr. Koyamataka Koyamataka, a digital and consumer electronics writer, whether there was a tips for replacing a TV or a useful life of TV for about 10 years.[Table] How many years can you use TV?A guide to the life of the main parts

The life of the display is 50,000 hours

Q.It is said that "the service life of TV has about 10 years", is it true?Koyama "It's true. The biggest reason is that the life of LCD displays and organic EL displays is generally said to be 50,000 hours. 10 hours a day, 36,500 hours in 10 years.If you leave it on a holiday, you will be closer to 50,000 hours. Of course, the shorter the time you are wearing the TV, the longer the dose of the display will be calculated, but electronic parts such as condensers other than the display.There is also a lifespan, and if you look at the whole TV, it is often the case that some parts may be defective around 10 years. Therefore, the life of TV is generally said to be 10 years. However, more than 10 years of problem.There are many products that operate without it. "Q.After the purchase, the TV that had been used for about 10 years broke down, so it seems that there were cases where it was refused when asked a contractor to repair it.Is it often not possible to accept repairs after 10 years after manufacturing or after purchasing?Mr. Koyama "It will often be excluded from repair. Because the Nippon Electric Industry Association (JEMA), a general organization in which home appliance manufacturers participate, set the holding period of repair performance parts for each home appliance.The TV parts are set for eight years. This is a regulation in groups, so some manufacturers may hold it for a longer period of time. However, basically, products are sold.After a certain period of time, the repair parts often disappear, so in that case, it will not be possible to repair it within the holding period. "Q..More than 10 years have passed since it was completely shifted to terrestrial digital broadcasting, so I think some people buy a TV due to failures. Please tell me the tips for replacing a TV. Koyama: "It is recommended to decide what to focus on when you buy a new TV. If you enjoy sports and movies, you will focus on image quality, and if you are mainly watching information programs and variety programs, A low -cost model with excellent cost performance is the best. Also, it is also a checkpoint that also has a recording function and whether it supports the flat -rate distribution service. If you value image quality or use many functions, the latest. The model is an option, but after about 10 years after use, the brightness of the screen may decrease. Let's choose it in consideration of aging. ".There are liquid crystal TVs and organic EL TVs on TV, but what is different? Please tell us about the advantages and disadvantages of each. Koyama "The LCD TV is a TV with LCD materials that change depending on the current on and off before the backlight (lighting on the back of the liquid crystal display). It is a low price, but it is black. The color is not good at expression and the color development is modest. OLED TV is a TV that uses spontaneous OLED material. The organic EL material shines, so you can draw a tight black color, always contrast (bright part. It is characterized by a high difference in light and dark from the dark part). Also, it has a high color reproducibility and is good at expressing fast -moving images. Instead, it is more expensive than the liquid crystal display. If you value image quality, it is recommended to choose an organic EL TV. ".Some electronics retailers offer paid long -term warranty services.Should I join a paid long -term warranty service when purchasing a TV?Koyama "Television is rarely moved, and there are not many fragile parts such as motors and inverters. Therefore, it can be said that it will be broken within the warranty period. However, LCD TVs and organic EL TVs broke down.In many cases, the substrate and panel are replaced during repair. At this time, replacement of the board costs at least tens of thousands of yen, and in the case of panel replacement, it may take the same amount as the purchase price of the TV itself.If you buy an expensive TV, it is recommended to enter a long -term warranty. "Q.Is it possible to have a TV that is no longer needed at a recycle shop due to replacement?Koyama "If there is no problem in operation within 10 years after manufacturing, there is a recycling company that will buy it. It is a good idea to check the purchase price on the website., Some major mass retailers also have a relatively new model and are in good condition, but if there are not enough accessories or failure or failure, it will be treated as a paid recycling.Television is a target item of the Home Appliance Recycling Law and cannot be used in general home garbage, so let's consult a new TV (such as a consumer electronics retailer).
