How to independently demagnetize the TV

Many owners of outdated TVs are wondering: how can you demagnetize a TV at home? People are faced with this problem when the device starts to malfunction, showing a distorted picture. This problem is inherent in most devices with a cathode ray tube and is called "magnetization."

Why is this happening

The main reason for the magnetization of the kinescope is the long presence of electronic devices in its immediate vicinity. In modern homes, this situation is not uncommon: microwaves, computers and telephones are present in almost every apartment. There is often a situation when the TV is put on the microwave, without thinking about it, but can i do it? If your unit has suffered from a regular stay in electromagnetic field - Do not rush to carry it to the workshop. You can solve the problem yourself. Depending on how strongly your TV is magnetized, you can repair it using one of two options:

• activate built-in magnetization protection;
• use a device called a choke.

Important: never use a permanent magnet for degaussing a kinescope.

We activate the built-in protection

Each CRT TV has, in its arsenal, built-in protection against magnetizing the screen - the so-called demagnetization loop. To put it into action, it is enough to turn off the device for a while and let the loop do its work.

You need to know that this loop starts working only when the device is disconnected from the power supply. The thing is that when the power is turned on, the voltage on the posistor goes continuously, and it cannot limit the power supply to the demagnetization loop. In this case, the demagnetization system remains inactive. Experts recommend periodically disconnecting the TV from the mains to prevent possible problems with the kinescope.

When choosing this option, it should be borne in mind that the loop cannot cope with the strong magnetization of the kinescope. In this case, you will have to resort to the second method.

Throttle degaussing

How to degauss TV at home with the help of a choke? To begin with, it is necessary to prepare the device for this process:

• disconnect the TV from the network;
• remove all electrical devices from the demagnetization site.

After the above steps, turn on the choke in the power supply and begin to carry out circular movements in a spiral, bringing it closer to the center of the kinescope. By carrying out such manipulations, pull the throttle away from the TV screen at a sufficient distance and turn off the device.

Important: the whole process of demagnetization should not take you more than 40-50 seconds, otherwise you can harm the kinescope of the TV.

Homemade choke

How to make a choke at home

You can assemble an electric magnet at home using an electric wire with a plug, an iron arc and a winding.

Take iron arc and connect it to the electrical network by connecting to a 220V wire. Insulate the device and turn it on.The sequence of actions is no different from the process of demagnetization by a special choke.

If you exactly followed the instructions in the article, but your device for watching television channels still shows poor-quality images or doesn't show it at all, possible reason - Shift Mask Kinescope Shift Mask. This fault cannot be repaired, and the only solution to the problem is to buy a new kinescope or TV. Now there are many models on the market, and in order not to be mistaken when buying, you need to know TV selection options. The best solution would be choice of modern TV with Smart TVworking on LED technology.
