- Page 59 Service manual SC-140 When the power switch is pushed on, V increases slowly. During this time, C806 is charged through R802. As soon as V reaches 16V, the STR-F6654 control circuit starts operating. Then, V is obtained by smoothing the winding voltage which appears between pin6 and pin7 of the SMPS transformer.

Service manual SC-140 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... - Page 65 Service manual SC-140...
