Deflecting yoke apparatus and television receiver

A television receiver comprising:

• a reception portion configured to receive a television broadcast signal;
• a signal processing portion configured to generate a video signal from the television broadcast signal received by the reception portion;
• a deflecting current generation portion configured to generate a deflecting current from the television broadcast signal received by the reception portion;
• a deflecting yoke portion configured to generate a magnetic field which deflects electron beams by using the deflecting current generated by the deflecting current generation portion;
• and
• a display portion configured to display the video signal generated by the signal processing portion as a screen image by deflecting the electron beams by using the magnetic field generated by the deflecting yoke portion,
• the deflecting yoke portion comprising:
• first and second frame coils configured to correct a vertical horizontal misconvergence in the screen;
• first and second main coils which are wound around a core and configured to defect in the vertical direction electron beams which have passed through a magnetic field generated by the first and second frame coils;
• first and second sub-coils which are wound around the core and configured to deflect in the vertical direction the electron beams which have passed through the magnetic field generated by the first and second frame coils;
• a first deflecting current supply portion configured to pass a serriform deflecting current to the first and second main coils;
• and
• a second deflecting current supply portion configured to supply to the first and second sub-coils through first and second diodes connected in parallel so as to have opposed directions a deflecting current which is supplied to the first and second main coils by the first deflecting current supply portion.
