1-2. Horizontal and Vertical processor IC03
1-2-1, Horizontal processor
IC03 performs following functions.
Horizontal Oscillstor
Sync Seperator
Horizontal Predriver
Horizontal AFC
Shunt regulator
This sync signal is inverted by inverting transisot 0601 and is fed back into pin 15 of IC03, and flyback pulse
into pin 14 of IC03. This two signal are compared and the circuit is locked to a correct frequency and phase.
1-2-2, Vertical processor
IC03 performs following functions
- Vertical oscillator
- Vertical predriver
- Vertical output
- Flayback generator
These are two vertical controls. One is V-size control VR502, The other is V-linearity control VR503.
