Temporary Turn On at Plug-in
When the A board receives the STB5V at pin 1 of connector A7from the power supply, it outputs the
“TV_SUB_ON” command for approximately 15 seconds.
This command is applied to the power supply board to generate the F15V. The F_STB15V is applied to
the A board.
The A board has a DC-DC converter circuit that generates the SUB voltages used by signal processing
circuit.
