* Schematic diagram for start-up operations
* TV start-up and microcontroller initialization.
- When AC POWER is on, rectified voltage is applied to transformer. T802. That voltage is rectified by
D801, D802, D803, and D804. T802. transformer is controlled by I802 and makes DC 5V at pin 11.
- When POWER SWITCH(SW01) is pushed on, voltage (5V / 3.3V) are supplied at I501 (pin3, 15 /
25,54).
- Reset voltage is applied at RESET pin(58) of I501.
- Microcontroller(I501) starts a initial operation, POWER(pin5) is high. Then the secondary voltages of
the T801 are applied.
- The microcontroller consults I502 EEPROM via IIC bus to know the last TV set mode (normal run
mode or stand-by mode) before switchins off.
