Dust has fallen on the TV, maybe not many people care, but it is known that this will have a great impact on health. A study shows that dust is an important carrier of electromagnetic radiation. When the TV is turned off, the electromagnetic radiation remains in the dust Here, like killers one by one continue to cause harm to our health. The dust in the TV set contains a carcinogen. Experiments have shown that if the TV is not rubbed for 3 consecutive days, the content of this carcinogen in the air will increase sharply. Dust will also overload electronic components, circuit boards and radiators frequently, resulting in increased power consumption. It can even burn electronic components and cause fire. In addition, the human body is also an electrical conductor. When electromagnetic radiation acts on the human body, it will also produce electromagnetic induction, and some energy deposition will eventually lead to abnormal cell function and cell state of the human body, changing the electrical conduction of nerve cells and disturbing the normal human body. Physiological activities, accumulated over time can also cause neurasthenia and neurological dysfunction. It can be seen that the harmfulness of dust is so great, so we have to learn to dust the TV. Of course, it does not mean that we just wipe it with a damp rag. Although it looks clean on the surface, some stains and dirt in the gaps still remain. In the above, there is no effect of dust removal. We all know that there are some heat dissipation holes on the top and side of the TV, and dust can easily fall into these places. If dust accumulates too much, it may damage the transistor and shorten the service life of the TV. To completely remove dust, the following methods can be used: 1. Add a small amount of softener to the clear water and mix well (the ratio of softener to water is about 1: 500). Put the towel in the softener solution and soak for 3 minutes. 2. Unplug the power of the TV. Wring the towel dry and put it on the radiator of the TV. Note that all heat dissipation openings of the TV must be covered with a towel. 3. Lift the corner of the towel, use a hair dryer to blow into the TV, and then blow it in from another heat dissipation opening. Because there are cations in the softener, which are positively charged, and dust has anions, which are negatively charged. After the dust in the TV is blown up, it will be adsorbed on the wet towel blocked by the heat dissipation port, and the purpose of dust removal is achieved. â— How to extend TV life? In fact, dust removal is only a job of TV maintenance. Nowadays, LCD TVs are becoming more and more popular, but LCD TV screens cannot be protected by film like mobile phone screens. Ultra-thin LCD TVs are hanging on the wall most of the time. What kind of daily care will increase the life of the LCD TV? We must keep in mind the following six points: 1. Don't turn off the TV Here is not to let everyone waste electricity, but to pay attention to weighing the impact of turning on the power supply on the life of the TV. As we all know, the backlight is one of the most serious parts of LCD TV accessories, and it is very similar to the fluorescent tube used in our home. Therefore, its service life has a great relationship with the number of ignition. During startup, the preheating and high-voltage pulsed cathode electron material sputtering increase, shortening the lamp life. If you develop the habit of turning off the TV casually, counting on four times a day will reduce the life of the lamp to 1/2. 2. Avoid working long hours This article does not conflict with the above notes. In the case of working for a long time, heat will accumulate inside the body of the LCD TV, which is not a big threat to other electronic components, but the LCD panel may burn out, resulting in large areas of bad spots. 3. Professional cleaning methods Due to static electricity, the screen surface of the LCD TV is easily contaminated with dust. But wiping with clean water is a very unwise cleaning method. The first is that the cleaning effect is average, and it is easy to leave water marks. More importantly, the liquid crystal is very easy to cause permanent damage due to moisture. If water droplets seep into the screen, avoid energizing and let the water slowly evaporate in a warm environment. 4. Avoid scratching or hitting the surface Many people use the habit of pointing their fingers at the screen, which is not important for CRT TVs, but it may cause fatal damage to LCD TVs. At the same time, they must take care of their children and their toys, any impact, scratch on the LCD screen Will bring direct damage, and it is very likely that the entire screen will be scrapped. 5. Water is the killer of LCD screen The LCD TV is very sensitive to humidity, and it has strict requirements on air humidity. If the humidity is maintained between 30% and 80%, the LCD can work normally, but if the indoor humidity is higher than 80%, the LCD TV has internal There may be condensation, which may cause leakage and short circuit of the LCD TV, or even burn the TV. 6. Do not disassemble without permission The high degree of mechanical precision of the LCD TV and the fragility of the core screen make the disassembly of the LCD TV unauthorized become a behavior that may cause greater damage to the TV. Even the shedding of a small metal scrap may cause serious consequences. At the same time, some of the LCD TV background lighting components will also carry a high voltage of about 1000 volts, which can also cause harm to the human body. When dust meets the TV, it will carry radiation and destroy our health little by little. Therefore, we must pay attention to the cleanliness of the TV. It is best to equip the TV with a TV cover if conditions permit, which not only prevents the entry of dust, Reducing the number of cleanings can also play a decorative role, why not do it? In addition, LCD TVs are becoming more and more popular, but if LCD TVs are damaged in any place, they will have to pay expensive fees. Therefore, we must develop a good habit when watching TV. Usually, multiple maintenances can also avoid unnecessary Troublesome maintenance.
