Instead of letting everyone waste power, they should pay attention to the trade-offs that affect the life of the TV. We all know that backlights are one of the most expensive parts of all TV accessories, and they are very similar to the fluorescent tubes used in our homes.
Therefore, its service life and number of ignitions also have a lot to do with it. The preheating and high-pressure pulsed sputtering of the cathode electron material at the time of startup increases, shortening the life of the lamp. If you develop the habit of turning off the TV, the life of the lamp will be reduced to 1/2 of the original four times a day.
Avoid working long hours
This article does not conflict with the above considerations. In the case of working for a long time, heat will accumulate inside the body of the TV, which is not enough threat to other electronic components, but it is likely to burn, resulting in a large area of ​​bad points.
Professional cleaning method
Due to static electricity, the screen surface of the TV is very susceptible to dust. But water wiping is a very unwise way to clean. The first is that the cleaning effect is general, and it is easy to leave water marks. More importantly, it is very easy to be caused by dampness.
Long-term damage (if water droplets seep into the screen, avoid energizing, let the water evaporate slowly in a warm environment.
Avoid scratching, twisting or hitting the screen surface
Many people use their fingers to point to the screen, which is not important for CRT TVs, but can cause fatal damage to TV, while watching their children and their toys, any impact or slash on the screen will take Direct damage and the possibility of scrapping the entire screen.
Still images can also damage the screen
At present, many TVs have digital photo browsing functions, but the display of a picture for a long time will cause damage to the screen. When not using the machine for a long time, avoid making the machine display a picture, it is best to turn off the machine. Although the heat of the TV set has been reduced a lot compared to the CRT TV set, the TV temperature problem is more sensitive. Displaying the unified picture for a long time will cause the fragile components to age. This may not burn the TV screen, but it may cause There are more dead pixels on the TV. The bad point is that it can only be white or black pixels and cannot be repaired. In order to cope with this problem, some products deliberately set the function of displaying the still picture for too long, and the TV automatically dims to protect the screen.
Water is a big killer of the screen
The humidity of the TV is very clear, and its air humidity requirements are more demanding. If the humidity is kept between 30% and 80%, it can work normally, but if the indoor humidity is higher than 80% (Southern Region), the TV interior There may be condensation, and this condensation may cause leakage and short circuit on the TV, and even severely burn the TV.
Do not disassemble and repair the TV
The CRT TV can not be repaired by itself, the mechanical precision of the TV, and the fragility of the core screen make the dismantling of the TV privately a behavior that may cause more damage to the TV, even if a small metal shavings fall off. Both can have serious consequences. At the same time, some components in the TV background lighting assembly also carry a high voltage of about 1000 volts, which can also cause damage to the human body.
