    1. Power Circuit 1.1 General Description This power unit uses a switching power supply. The switching frequency is synchronized within the range of the horizontal frequencies (31kHz to 96kHz). 1.2 EMI Circuit The EMI circuit comes in a two-stage configuration. The first stage is composed of the choke coil in the common mode and the capacitor X.

  • Page 113: Starter Circuit

    1.7 Starter Circuit When the power switch is turned ON, Q102 is turned ON and a charging current flows into C111 through R102, R103, Q102, and D105. When the voltage at U101 Pin 7 reaches 16V, the U101 begins to oscillate. When the U101 begins to oscillate, the currents consumed in U101 and Q101 increased.

  • Page 116: Deflection Circuit

    3. Deflection Circuit 3.1 Deflection Control IC (IC501) IC501 is in charge of the horizontal width control and the generation of vertical pre-amplifier output. This IC follows the input frequency and generates a proper output of horizontal drive pulses. For the screen size control, this IC also generates the B+ output drive pulses.

  • Page 117: Horizontal Deflection Circuit

    3.2 Horizontal Deflection Circuit 3.2.1 Horizontal Oscillator Circuit The outputs of the horizontal oscillator drive pulses (Pin 8 H_DRV) and the Power B drive pulses (Pin 6 B_DRIV) are generated from the U501 (TDA4856). The horizontal drive pulses of about 10Vp-p are output from Pin 8 (H_DRV) in the open collector mode. The duty cycle is about 50% and its frequency is dependent on the input horizontal sync frequency.

  • Page 118: Horizontal Width Control Circuit

    3.2.3 Horizontal Width Control Circuit Q314 is controlled by the horizontal drive pulses from IC501. While Q314 is turned ON, the energy is stored in the horizontal deflection yoke. When it is turned OFF, the stored energy flows into C331 and C332. This operation is repeated to maintain the horizontal deflection.

  • Page 119: Horizontal Output Circuit And Horizontal Feedback Circuit

    3.2.5 Horizontal Output Circuit and Horizontal Feedback Circuit The horizontal output circuit is composed of the horizontal transistor Q314, the damper diode D317, the resonance capacitor C332 and the deflection yoke (H_DY). When the base current fed from the drive circuit is turned ON, a deflection current flows into the horizontal transistor Q314 for the specified time period.
  • Page 120 3.2.6 Linear Correction Circuit and “S” Correction capacitor Circuit The horizontal linearity correction circuit uses a variable linear coil (T303). The variable linear coil T303 is used to control the current with the aid of Q310, R339, C322, and C323 which flows in the primary side of the coil.

  • Page 121: Centering Circuit

    3.2.7 Centering Circuit The horizontal raster centering circuit is inserted between the horizontal deflection source circuit and the horizontal deflection output circuit (H_DY). This circuit is used to assure a current flow of the DC current bias component in order to shift the deflection current waveform toward the horizontal deflection circuit. The inflow current is controlled through the adjustment of VR501.

  • Page 122: Vertical Deflection Circuit

    3.3 Vertical Deflection Circuit 3.3.1 Introduction The vertical deflection circuit gains an input of vertical saw-tooth wave signals generated from the oscillator IC501 Pin 13 Vout1 and Pin 12 Vout2. The resultant output signal is converted into a current that drives the DY (V) through the use of the U401 (TDA8172) driven by +14V and -12V of the power supply.
