The TV is always affected by the magnetic force when it is used. Under normal circumstances, the TV can automatically degauss, but when the TV is not protected, the internal magnetization of the TV needs to manually degauss the TV. , then how does the TV degauss? The following decoration home decoration network Xiaobian will bring you a detailed explanation of the TV degaussing method, I hope to be helpful to everyone.
What is the reason for the magnetization of the TV?
It is necessary to know that the TV can automatically degauss under normal conditions. However, when the TV is too strong, it will easily cause the TV to be automatically degaussed. The circuit components of the TV are again magnetized by the external strong magnetic field. . The occurrence of remanence in the process of degaussing the TV also causes magnetization of the internal magnetoresistance of the TV. The magnetization of the TV set can easily cause the magnetization of the TV picture tube, and the color and color deviation of the TV screen appear.
Introduction to the principle of TV degaussing:
Generally, when the television is in the process of degaussing, its degaussing circuit is composed of two parts, which are respectively a degaussing coil and a degaussing resistor. The degaussing resistance of a TV set is a kind of non-linear resistance, which we usually call "PTC resistance". The Curie point of the degaussing resistance of a television set is generally several tens of degrees, and its blocking at normal temperature is generally ten or more ohms.
During the booting process, the TV will have a large current flowing through the degaussing circuit of the TV, and a demagnetizing magnetic field is generated in the degaussing circuit. When the degaussing magnetic field stops working, the PTC resistor will still have a residual current. During the shutdown process, the residual current will magnetize the picture tube at the moment of shutdown. This phenomenon is very harmful to the TV's phenomenon tube. Therefore, the TV usually turns off the degaussing when the computer is turned on, disconnects the circuit and the power supply, and avoids the magnetization of the TV.
How to degauss the TV?
The method of degaussing the TV is very simple. We also need to pay attention to the use of the TV when using the TV every day. When the TV shows magnetization, we can disconnect the TV power for about 20 minutes before turning on the TV. Usually this method can reduce the color shift phenomenon of TV caused by the magnetization of the TV to some extent.
A special degaussing coil can also be used when solving the magnetization phenomenon of the TV. At this point, you need to turn off the power of the TV set for a few minutes and then turn it on again. After the TV is turned on, the degaussing coil is inserted into the power supply, and the degaussing coil is slowly approached to the TV screen, the degaussing coil is moved toward the screen, the spots appearing on the TV are eliminated, and finally the degaussing coil is away from the TV. The above method can be repeated when the degaussing effect of the TV is not obvious.
The above is how the TV set that Xiaobian brings to you degaussing? For the detailed explanation of the TV degaussing method , I believe that everyone has a basic understanding of how to degauss the TV after reading this article.
