How can I demagnetize the TV?

The problem of color distortion and the appearance of increasing bands of different colors along the edge of the screen usually occurs in TV sets with a CRT (CRT). Many believe that their TV has completely broken down, and they are buying a new one. But in fact, this defect can be easily eliminated, since these problems are a consequence of the excessive magnetization of the television picture tube, that is, we simply have to demagnetize it.

Why is the TV screen magnetized?

This happens if electrical appliances are located near the TV, creating a magnetic field in their work. This is a column, and a music center, and a computer.

How can I demagnetize the TV screen?

There are two ways to demagnetize a kinescope:

1 way - automatic

You simply turn off the TV, disconnect it from the electrical network and leave it at rest. Due to the fact that the demagnetizing loop of the tube is located inside the TV, the defect should be eliminated the next time it is turned on. The period of rest period for each TV is different.

In more modern models of TVs in the monitor menu there is a demagnetization function. To use it, you just need to find this function and enable it. After that, the screen turns off for a few seconds.

If this method does not work, you need to use the following.

2 way - with the help of a demagnetizing choke

Remove all electrical appliances near the TV.

1. Turn off the TV and unplug the power plug.
2. Take the throttle.
3. Turn it on at a distance of 50 cm from the screen.
4. Performing circular motions in a spiral, you need to bring the device closer to the center of the tube by 2 cm.
5. We move the throttle from the edge to the center (concentrically), and then in the reverse order.
6. We move it away from the TV in a circular motion for some distance.
7. Turn off the device.

All of the above should be done in 40 seconds.

Before you start demagnetizing the TV screen with a throttle, be sure to consult a specialist. You should know that you can only demagnetize the CRT TV, but not the LCD , since its operation is arranged in a different way.
