(Fig3. Block Diagram of IC201.)
Horizontal Scanning Section
The horizontal drive signal send out from pin 56 of IC201, Q401 is horizontal driving transistor,
coupled by horizontal driving transformer T402 , to control the horizontal output transistor
working in switch on and off situation, get good linearly and enough amplitude of saw-tooth wave
current to drive horizontal deflection yoke scanning. L456 is horizontal width coil and L458 is
horizontal linearly coil. D455 is damping diode, C453,C455,C457 are retrace capacitors. T401 is
FBT. Pin2 of T401 is B+ voltage input, Pin 10 of T401 get 200 Volt video amplifying voltage
supply for CRT board. Pin11 of T401 sends out heater voltage supply for CRT heater.
