* power supply functioning during TV set normal run mode<br />
- I801 transmits controlled pulses to T801 which generates DC voltages after rectifications by secondary part diodes<br />
and electro capacitors (by example by D820 and C813 on 143V supply voltage line).<br />
- 8V, 5V, 3.3V supply voltage lines have stabilized voltages obtained by I820, I822, I823 voltage regulators.<br />
- On 143V supply voltage line, R823 resistor has been chosen to reach exact DC voltage required on this line.<br />
- 143V supply voltage line includes an IC error amplifier (I806) which corrects unexpected DC voltage variations on<br />
this line.<br />
