Today, the small lemon green to tell you some smart boxes, smart TV maintenance methods, allowing you to effectively extend their life and maintain the quality of use.
Most of the smart TVs and smart boxes in the market today use Android. Just like Android phones, they don't know how to use them for a long time. 
Hardware aspects:
Remember to shut down properly
There are many pros who use smart boxes. When you are used to turning off the TV, you are not connected to a smart box. The damage to the smart box is so great that your computer is always on without stopping. So be sure to turn off the smart box and turn off the TV.
Today, many smart TV box manufacturers have eliminated the power switch function, but they still can find physical switches on the old smart TV boxes of Kaibol and Haimeidi. If your home smart TV has a physical switch, remember to turn it off.
Remote shutdown is not a complete shutdown, it is equivalent to standby, so be sure to turn off the physical switch.
The above behavior not only consumes energy and wastes resources, but also is very dangerous. There have been news reports and news that televisions have been on standby for a long period of time. Therefore, whether it is power saving or security, when smart TVs or smart boxes are not suitable, they must be Remember to turn off the power really. 
Because the sudden change of current can easily damage the fragile circuit of the equipment, although the probability of such damage is relatively small, the damage to the equipment is usually irreversible. If it happens, it can only be changed again.
2. Do not use in extreme environments/states
Although technology is very advanced today, high-tech products are still fragile. Just like mobile phones, you fall several times and then go into the water, and you are almost taking its life. Smart boxes and smart TVs are also high-tech products. They also need to be used carefully to better extend their life. 
Keep smart TVs or boxes in a dry place in a cool place to avoid direct sunlight, away from water sources and wet environments. Especially during rainy days, special treatment should be done, such as standby for a while.
In bad weather, such as typhoon days, when lightning is severe, it is better not to use it, so as to avoid circuit damage when power is cut off.
Smart TVs and smart boxes need to be placed in a stable place. If they cannot be protected with a dust cover, they must be wiped regularly.
Although the wall-mounted smart TV saves space, it is less effective than the TV cabinet.
3. Avoid collisions and beats
For any smart product, collision and beating are the worst. In particular, the screen of a smart TV has direct damage to any impact or scribing of the LCD screen, and it is very likely that the entire screen will be scrapped.
Smart boxes also try not to beat and collide, especially if there are children at home, they may not understand it, they can use it, and if they accidentally shake off or beat them with their hands, they will not only hurt the smart box, but also have security risks. 
With the demand of the market, the interfaces of smart TVs and smart boxes are becoming more and more abundant, and attention must be paid to the insertion and extraction of these interfaces.
Smart TVs and smart boxes generally do not support hot plugging. Whether you unplug the U disk or unplug the cable, do not operate it at boot time. The correct method should be pulled out after the system is set up or shut down, if you are reading Unplugging the memory card while taking the contents of the storage device can also cause the system to crash or even destroy the main board of the box! 
The above is the maintenance of the hardware, in fact, this is also the use of habits to develop, to develop such a habit, whether it is a computer or a mobile phone, can be better protected, extend the service life, the machine is also a person, remember gentle treat!
Software:
1. Third-party applications, install cautiously
One of the reasons for the popularity of smart TVs and smart boxes is precisely because they are open-ended. In addition to the original features, it is also possible to add content or functionality by installing third-party applications.
This naturally brings us a lot of convenience, but the forest is big, what birds have, not all applications are safe and legal, in particular, many people will get outcast resources in the future, casually find a bunch of live sources on the Internet, and then install the application , insert the source of live broadcast, and found that it is a virus. 
2. Regular cleaning of garbage
Just as mobile phones and computers need to regularly clean up memory and garbage, smart TVs and smart boxes also require you to clean up spam on a regular basis. Otherwise, these spam will occupy your memory, boot time will be slow, and you can easily use it. People familiar with electronic products can easily understand this.
3. Ensure good network connection and use high quality network
Smart TVs and smart boxes are nothing different than traditional TVs if they are not connected to the Internet. Most of the time, you don't watch smart cards or smart boxes. The current smart product configuration is very high. Unfortunately, the quality of the Chinese network is still not keeping up. Caton is really because the Internet can't keep up. 
Jailbreaking sounds great, but if you don't specifically understand it, it's not an easy attempt at ROOT cracking. Although ROOT crack, the user has the highest authority of the smart TV device, you can optimize the device for any streamlined optimization, but there is a saying "do not die will not die", many users of smart TV and TV box are The ROOT cracking process leads to a brick...
Although many smart TVs or TV boxes have a lot of “junk†content built in at the factory, Xiao Bian still has to advise everyone to try to avoid ROOT cracking if it is not necessary!
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
Smart boxes and smart TVs are prone to becoming dull for a long time, or they are prone to crash. Sometimes they even hang directly. This is like a cell phone, electronic products do have such problems, but if you know how to maintain, then you can greatly delay its life and maintain quality. Therefore, we can maintain smart TVs and smart boxes from two aspects, "Hardware" and "Software". Also, if a short circuit or thunderstorm occurs in your home, the correct method is to turn off the smart TV and the box system first, and then disconnect the power of the equipment. The so-called extreme environment, that is, the environment that is not suitable for the use of smart TVs, including wet, gray, overheating, bumps, strong magnetic fields, and continuous use for a long time, etc., will aggravate the wear and deterioration of smart TV electronic components. 4. Do not plug in or pull out the switch If it is not an old TV, please use the HDMI HD cable as much as possible to connect the TV. This will not only ensure the clarity of the video transmission, but also reduce the energy consumption of the box motherboard. Therefore, before choosing an application, be sure to choose safe as much as possible and try not to use applications of unknown origin. Therefore, choosing a quality network is one of the quickest shortcuts for smart products. The same high-quality network can also reduce the damage of smart TVs and smart boxes. When it comes to cards, smart TVs and smart boxes are doing their best. 4. The so-called crack, you are not an expert, do not just crack ROOT
