The STB5V from pin7 of connector P2 is applied to the Analog ASIC (IC5000) for
supplying power to the Main CPU/PEAKS (IC8000) on the A board. The Analog ASIC
(IC5000) converts the STB5V to STB3.3V. This voltage energize and prepare the
microprocessor (CPU) for program execution. The STB3.3V from the Analog ASIC (IC5000)
is also applied to the remote control receiver and the power LED on the K board through pin
5/8 of connector A11/K10.
When the Power Switch on, the key3 signal is grounded. (#1)
The IC8000 lights on the RED LED and is ready to power on the TV by receiving the Power
switch on, Remote on, Viera Link and so on. This is a standby state.
(#1)Only North America model:
When the power on command coming from the power switch (or remote control) is
provided to IC8000 PEAKS, the IC8000 first outputs the "TV_SUB_ON" command. The
"TV_SUB_ON" command is provided to power board via pin 9 of connector P2.
(#) Just after transition to Stand-by mode, the TV_SUB_ON(16V) is output for few minutes.
