Power On Operation

The power command from the power switch on the S board or the remote control receiver on the K board is
provided to the CPU in the A board. The CPU on the A board outputs the “PANEL_STB_ON” command and
the “F_STB_ON” command. The “PANEL_STB_ON” is provided to the D board to turn on the STB3.3V
regulator. The output voltage is applied to the CPU in the D board. The “F_STB_ON” command is provided
to the power supply to develop the F_STB+15V.
When the CPU on the D board is energized, it outputs the “PANEL_MAIN_ON” command to the power
supply. This command turns on the power supply circuit that outputs the Vsus, Vda, 15V, and 5V.
