Field excitation pulse input N402 (TA8859) 2 foot parabolic wave output voltage is amplified by the V401 ~ V403, and outputs the parabolic wave by V403 collector. It will be sent to the line deflection coil and change the flow through the line deflection coil current. That is, completion of the East / West pincushion correction. The east / west pincushion correction is sent to bus adjustment mode. Pin 1: 3.7V-- high stability detection input Pin 2: 1.1V-- something the school pillows parabolic wave output Pin 3: 12.0V-- +12 V voltage input Pin 4: 5.5V-- something the school pillows feedback input side Pin 5: 0V - to Pin 6: 4.2V-- the input field scanning FeedbackPin 7: 0V Pin 8: 2.1V-- Field sawtooth voltage output Pin 9: 4.8V-- Bus cable connector Pin 10: 4.8V-- Bus clock line Pin 11 connector: 0V- - empty pin Pin 12: 0V - to Pin 13: 4.4V-- field excitation pulse signal input Pin 14: 3.8V-- external pulse shaping filter side Pin 15: 6.0V-- field scanning ramp voltage to form side Pin 16: 3.0V-- end automatic gain control filter
