PROBLEM TO BE SOLVED: To provide a demagnetizing circuit which is capable of carrying out a necessary demagnetization process when a television set is deteriorated in color purity in the case that the television set is brought in by a user as its power supply is kept in an on-state. SOLUTION: The demagnetizing circuit is equipped with a demagnetizing coil connected to a DC power supply, a parallel circuit unit composed of a capacitor and a resistor and connected to one end of the demagnetizing coil whose other end is connected to the power supply, and a manual switch which is connected to one end of the parallel circuit whose other end is connected to the demagnetizing coil. The one side of the manual switch whose other side is connected to the parallel circuit is connected to the ground. COPYRIGHT: (C)2007,JPO&INPIT
