1. Structure of the Pick-up
SF-HD67 is consist of monitor diode for DVD laser and CD laser.
When DVD laser is ON, CN101 20 Pin is need to connect GND for getting monitor voltage.(CN101 22 pin).
When CD laser is ON, CN101 19 Pin is need to connect GND for getting monitor voltage.(CN101 22 pin).
This control is done by handling Q102,Q104 from CD signal (IC201 175 pin output).
