How to demagnetize a TV screen

Disconnect the TV from the mains and wait until the PTC (a thermistor with a positive thermal coefficient of resistance) in the circuit loop of the demagnetization cools down. It may take up to half an hour. Then restart the machine. There will be an automatic demagnetization. If it does not work, repeat the procedure several times.

The monitor is usually a relay that disables the connection and the coil from the mains once carried out its demagnetization. So it cools even when the monitor is enabled. Again to demagnetize the picture tube, it is sufficient to select the menu display option called Degauss. Remember, again successfully demagnetize the mask of the tube will be only half an hour (until the connection is hot, when you select the corresponding menu item, the relay is clicking, but the demagnetization is not performed, and moreover, every such attempt to re-warm up the connection).

If the picture tube is magnetized so much that demagnetize its internal loop fails, use an external demagnetizing inductor. Take it for a while in teleatele. Remove from the room at the time of any diskettes, audio and videotapes, Bank and discount cards, tickets with magnetic stripe - all of which can be degaussed with your TV or monitor. Turn on the TV or the monitor, put the throttle a few meters away from him, then turn in too. Slightly moving the throttle from side to side, slowly put it close to the machine, it will cause severe color distortion. As slowly take it back, and only a few metres from him off. Then the color distortion should disappear. If not, repeat the procedure several times. Do not hold the throttle for a long time included to exclude heat.

In the case, even if the demagnetization of the external choke is not led to the desired result, the apparatus is disturbed convergence. The adjustment entrust to a specialist. This is connected not only with a TV or monitor high voltages, but with the complexity of the procedure - it will take not even just the technician.
