  • Page 51 APPENDIX FUNCTIONAL DESCRIPTION 9-1-2. TV start-up and microcontroller initialisation - When SW801 power switch is pushed, main AC voltage is applied to T801 transformer (after rectification by D801...D804 diodes). Then, T801 SMPS transformer starts operating and supplies DC voltage to I823 (3.3V regulator). - This regulator provides 3.3V DC voltage to I501 microcontroller power supply pins (pins 54, 56, 61) and to the reset pulse cir- cuit which provides reset pulse to I501 microcontroller reset pin (pin 60).
  • Page 52 APPENDIX FUNCTIONAL DESCRIPTION 9-1-4. Reset pulse circuit operations description - When DC supply voltage from I823 regulator starts rising (from 0V to 1.2V), no current flows through D591 zener diode. So, Q510 is in off mode. Also V =Vcc/2 -Vcc = -Vcc/2 > -0.6V. So, Q511 is in off mode. be Q511 Then, no voltage reaches I501 pin 60.
  • Page 53 APPENDIX FUNCTIONAL DESCRIPTION In normal run mode, I501 microcontroller pin 63 (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 11V 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.
