6-11 HORIZONTAL DRIVE & OUTPUT CIRCUIT SECTION
Horizontal drive receives pulse from TDA9102C Pin 6 (varies according to frequency) and
applied to Q401 base. Then Q401 repeats on and off according to the pulse. At this time,
pulse is generated in T401 and operates T401.
When T401 operates, pulse separated from the secondary side of T401 can drive horizontal
so that it supplies pulse to Q402 base, and repeats on and off by pulse and the operation
can drive FBT. C402 and C403 generates pulse and supplies it to horizontal deflection, and
900V~1000V Vcp voltage is applied to T402 Pin 1 and this voltage varies with voltage
supplied to T402 Pin 2 (this voltage is supplied from SMPS according to horizontal
frequency). The supplied Voltage is raised in T402 and output as high-voltage, screen
voltage and focus voltage.
V/R401, horizontal raster position control VR, receives - voltage from T402 Pin 3 and +
voltage from Pin 4, and varies DC voltage with Q403 and Q404 to move horizontal raster
toward the right and left side.
