彩电受到外界磁场的磁化时,会造成偏色、彩色失真等故障现象。如受磁化较轻,彩电内部的消磁电路会自动进行消磁。但当受磁化较严重时,则必须借助消磁器方能消磁。 笔者在实践中发现用交流接触器线圈作消磁器效果很好,取一线圈完好的220V交流接触器,取出线圈及一半“山”型铁芯,将一半铁芯插入线圈,接入 Color TV by the external magnetic field magnetization, can cause color cast, color distortion and other symptoms. Less susceptible to magnetization, color TV internal degaussing circuit will automatically degaussing. However, when the magnetization is more serious, you must demagnetize degaussing. In practice, the author found that AC contactor coil demagnetizer works very well. Take a 220V AC contactor with good coil, remove the coil and half of the “mountain” type iron core, insert half of the iron core into the coil,
