With the strong involvement of Internet companies, the products on the smart TV market are changing with each passing day, and their prices have entered the era of parity. However, for consumers, buying TV back is a big object anyway, and it will be carefully considered when buying. Today's profiteers have many tricks, shoddy, and old things are constantly emerging, the most common is to fake the hardware parameters of smart TV. Or if the old TV in the home has blue screens, screens, or system crashes, they are afraid to get it, and the maintenance personnel are simply restoring it through the “factory/engineering modelâ€. In view of these circumstances, today's sofa assessment team will discuss how to enter the "factory/engineering model" for several branded smart TVs currently on the market, and view the hardware information and recovery system of the TV. 
Consumers who know TV know that every TV can enter the "factory/engineering mode", and in the "factory/engineering mode", users can watch the TV's running time and use panel type information, The system performs reset recovery and so on, so as to avoid being deceived by individual unscrupulous merchants.
Although the method is very practical, entering the "factory/engineering mode" requires a specific "password". The method of different CPU chips is also different. The average consumer really does not know. Today, Xiao Bian has collected all the major brand TVs that need to be put into the "factory/engineering mode". If everyone has plans to buy TV, they can learn about it.
Millet TV 
First of all, let's take a look at Xiaomi TV, which everyone is very concerned about. Take Xiaomi TV 2 as an example:
Enter factory mode steps:
1. In the system menu, enter "Settings" - "About" - "Contact Customer Service";
2. In the "Contact Customer Service" interface continue to press the "down" direction key of the remote control, you can see the "factory mode" entrance; 
It should be noted that the "factory model" of Xiaomi TV is to bring out the ADB mode and use it by professional programmers for testing and maintenance. The average user does not need to enter the "factory mode."
Enter engineering mode steps:
1. Shut down first
2. Press and hold the “Home†and “Menu†keys on the remote control at the same time, and aim at the millet TV infrared receiver;
3. Touch the millet TV switch (breath light), and the remote control buttons should not be loose;
4. Until the screen appears the following recovery interface, select to enter (careful operation); 
It can be seen that the millet TV is a dual system, which is a native system and a recently updated system, and one dead one can be re-elevated by another.

LeTV has recently accumulated good popularity among consumers, taking LeTV S50c as an example:
1. While opening the LeTV S50c, press and hold the "source button" of the remote control;
2. Under the premise of not releasing the "source button", press "2", "5", "8", "0" in sequence; 
However, LeTV's method of entering engineering mode cannot be applied to all models. It is recommended that users confirm whether their models can enter before actual operation. Detailed LeTV usage experience can be communicated with LeTV users in the corresponding forum of the sofa forum ( Http://bbs.shafa.com/forum-93-1.html)

1. Press the four keys “Displayâ€, “Projectâ€, “Muteâ€, and “Power†in the power-on standby mode, and wait for a while to enter the project mode.

3. Press the number key "5" on the remote control;
4. Press the Volume - button on the remote control.

Last but not least! All the above operations must be completed in "2 seconds"! 
Don't you know that the users of Sony TVs do not want to cry at the moment they see the project interface? After a few trials, it is easy to operate after being familiar with it.
to sum up:
In the process of editing, how different brands of different types of smart TVs enter the “factory/engineering model†is just a matter of fighting with the engineers... But it's easy to think back when you think about it again. The “factory/engineering model†was If you enter the TV system layer, if you can enter it casually, ordinary users will cause irreversible losses due to hand misunderstandings. Therefore, Xiaobian also cautioned everyone here that the “factory/engineering model†still has to be tried on the basis of certain theory and practice.
