Service manual SC-150

On normal run mode, I501 microcontroller pin 1 (power) is set to high

So, I810 controlled rectifier is not conducting

-Q809 is conducting. So, Q808 is not conducting and Q807 is conducting

-So, Q807 collector is connected to the ground and I810 controlled rectifier gate pin is set to low (no conducting)

So, current from 14V DC voltage (from T801 SMPS transformer pin 13) does not flow through Q811 and Q810 transistors but flows through I806 IC error amplifier

-Q809 is conducting. So, Q810 is not conducting and no current flows from Q810 collector to the ground Therefore, the power circuit diagram is the following one :
