(1) Video signal and Y/C signal The LINE A/B video signal that is selected by the VIDEO switch on the Q board, or the Y signal from the Y/C input of LINE A connector, is input to the B board from CN103 pin-1, and then to IC104 (CXA2163AQ) pin-1.
  • Page 52 2. CXA1739S peripheral circuit IC231 (CXA1739S) accepts the Y/Cb/Cr signal from 1. -(2) at pin-1 (Cr), pin-2 (Cb) and pin-3 (Y). It also accepts the RGB signal from 1. -(4) at pin-10 (R), pin-11 (G) and pin-12 (B). Either one of these two input signals is selected inside the IC.
  • Page 53 5-2. Defection and High Voltage Circuit 1. Sync Signal Processing Circuit The horizontal and vertical sync signals that are input from the G board CN1502 (pin-4/pin-12), are sent to the defection signal processor IC1551 (pin-26/pin-28). In IC1551, the horizontal drive waveform, dynamic focusing parabolic waveform, picture distortion correcting parabolic waveform, vertical drive waveform and H/V blanking waveforms that are required by the deflection circuit, are generated and output.
  • Page 54 5-3. Power Supply Circuit The power supply block consists of the following two switching regulators. 1. The power regulator for improving power factor to conform to the power supply harmonics regula- tion. 2. The power regulator for the main power supply that supplies the necessary voltages to the signal system circuit and to the deflection and high voltage circuits.
  • Page 55 3. Overvoltage protection and over-current protection circuits The +115 V power line of the main power regulator has the over-voltage protection and over-current protection circuits in order to protect the power supply circuits and the loads in the case of abnormal load and when the voltage-feedback system becomes defective.
